  • Open-label trial of atomoxetine hydrochloride in adults with ADHD.
  • 2010
  • In: Journal of Attention Disorders. - : SAGE Publications. - 1087-0547 .- 1557-1246. ; 13:5, s. 539-545
  • Journal article (peer-reviewed)abstract
    • Background: While atomoxetine is an established treatment for attention-deficit/hyperactivity disorder in children, few studies have examined its efficacy for adults. Methods: Open-label trial of atomoxetine in 20 individuals with ADHD, aged 19-47 years, for 10 weeks, and a total of one year for responders. Results: Ten patients met primary efficacy criteria at 10 weeks. Only one patient completed the whole study. Six patients discontinued before 10 weeks and thirteen at 10 weeks or later, mainly because of side-effects (aggression, depressed mood, raised liver enzymes, thyroid hormones, diastolic blood pressure), decreasing efficacy or non-compliance. Conclusion: Fifty percent responded to treatment, but only one patient (5%) felt sufficient improvement to continue for one year. Dosage may have been too low, and baseline impairment too high, for atomoxetine to have sufficient effect on ADHD symptoms in our group of adults. The majority had few side-effects, but several terminated treatment because of adverse effects.

  • National cohort of infants born before 24 gestational weeks showed increased survival rates but no improvement in neonatal morbidity
  • 2022
  • In: Acta Paediatrica. - : Wiley. - 0803-5253 .- 1651-2227. ; 111:8, s. 1515-1525
  • Journal article (peer-reviewed)abstract
    • Aim To describe survival and neonatal morbidities in infants born before 24 weeks of gestation during a 12-year period. Methods Data were retrieved from national registries and validated in medical files of infants born before 24 weeks of gestation 2007-2018 in Sweden. Temporal changes were evaluated. Results In 2007-2018, 282 live births were recorded at 22 weeks and 460 at 23 weeks of gestation. Survival to discharge from hospital of infants born alive at 22 and 23 weeks increased from 20% to 38% (p = 0.006) and from 45% to 67% (p < 0.001) respectively. Caesarean section increased from 12% to 22% (p = 0.038) for infants born at 22 weeks. Neonatal morbidity rates in infants alive at 40 weeks of postmenstrual age (n = 399) were unchanged except for an increase in necrotising enterocolitis from 0 to 33% (p = 0.017) in infants born at 22 weeks of gestation. Bronchopulmonary dysplasia was more common in boys than girls, 90% versus 82% (p = 0.044). The number of infants surviving to 40 weeks doubled over time. Conclusion Increased survival of infants born before 24 weeks of gestation resulted in increasing numbers of very immature infants with severe neonatal morbidities likely to have a negative impact on long-term outcome.

  • A comparison of North American versus non-North American ADHD study populations.
  • 2006
  • In: European Child & Adolescent Psychiatry. - : Springer Science and Business Media LLC. - 1018-8827 .- 1435-165X. ; 15:3, s. 177-181
  • Journal article (peer-reviewed)abstract
    • Few large, prospective clinical studies in Europe have assessed the validity and applicability of research methods used to study ADHD in North America. To assess comparability of study populations, we examined baseline patient characteristics from a group of North American studies against those of a large European/African/Australian study. All studies used identical diagnostic assessments and inclusion criteria, with ADHD diagnosis and the presence of comorbid psychiatric conditions confirmed using the KSADS-PL. Raters were trained and assessed to ensure uniform diagnostic and symptom severity rating standards. Six hundred and four patients (mean age = 10.2 years) enrolled in the non-North American study, and 665 patients (mean age = 10.4 years) enrolled in the North American study. The proportion of girls was higher in the North American studies (29.2% vs. 10.4%, p < 0.001). In both groups, most patients had a positive family history of ADHD and previous stimulant treatment. Fewer had the inattentive subtype of ADHD, and mean severity was slightly higher in the non-North American study. Results demonstrate that, when a uniform set of rigorous, standardized diagnostic criteria are used by skilled clinicians, the patient populations identified are generally similar. This supports the practice of generalizing results from treatment studies across geographies.

  • A prospective, multicenter, open-label assessment of atomoxetine in non-North American children and adolescents with ADHD.
  • 2004
  • In: European Child & Adolescent Psychiatry. - : Springer Science and Business Media LLC. - 1018-8827 .- 1435-165X. ; 13:4, s. 249-257
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE: The aim of this study was to study treatment response to atomoxetine in a large, multicenter study of non-North American patients with ADHD. METHODS: A total of 604 children and adolescents with ADHD were enrolled in a 10-week open-label trial with atomoxetine prior to randomization to a double-blind relapse prevention phase at 33 sites in the United Kingdom, continental Europe, Israel, South Africa, and Australia. All patients had ADHD symptom severity at least 1.5 standard deviations above United States age and gender norms for their diagnostic subtype as measured by the investigator-scored ADHD Rating Scale (ADHD RS). Outcomes were assessed by analysis of change in the ADHD RS; functional and psychosocial outcomes were assessed using the Child Health Questionnaire (CHQ). RESULTS: At endpoint, ADHD RS total scores decreased by an average of 56.7%, and 69% of patients were rated as having no or minimal symptoms. Significant improvement was observed in psychosocial and functional outcomes. Discontinuations attributed to adverse events were < 4%. CONCLUSION: These open-label data, gathered in an international setting, add to our knowledge of the value of atomoxetine in treating ADHD symptoms, as well as its safety and tolerability.

  • Monitoring medication response in ADHD: what can continuous performance tests tell us?
  • 2022
  • In: European Archives of Psychiatry and Clinical Neuroscience. - : Springer Science and Business Media LLC. - 0940-1334 .- 1433-8491. ; 272:2, s. 291-299
  • Journal article (peer-reviewed)abstract
    • Documenting effectiveness of ADHD medication is essential throughout the course of treatment. A rating scale and a continuous performance test (CPT) with motion tracking were used to study the effect of ADHD medication including compliance during one year. Children (N = 78, age 6-18 years) with ADHD were tested with the QbTest at baseline, visit 1 (1 month after baseline) and visit 5 (12 months after baseline). The ADHD-Rating scale was rated by investigator interview at the same visits. QbTest results and ADHD-RS ratings showed reductions in symptoms on all cardinal parameters of the QbTest and on all ADHD-RS subscales between baseline and 1 month and between baseline and 12 months. There was a weak but significant correlation between the total change scores on the two measures from baseline to 1 month. Eighteen participants dropped out of the study before visit 5; at baseline, these children showed significantly lower results on the inattention parameter of the QbTest, with faster reaction time and lower variation in reaction time, suggesting they suffered less problems with inattention. Both the QbTest and the ADHD-RS showed robust ADHD symptom improvements indicative of medication effect, and the QbTest results might also predict non-compliance of medication. Further research is warranted to increase knowledge about reliable monitoring of long-term medication and compliance.

  • Paediatric Acute onset Neuropsychiatric Syndrome: Exploratory study finds no evidence of HLA class II association but high rate of autoimmunity in first-degree relatives
  • 2022
  • In: Acta Paediatrica. - : Wiley. - 0803-5253 .- 1651-2227. ; 11:4, s. 820-824
  • Journal article (peer-reviewed)abstract
    • Aim Paediatric acute-onset neuropsychiatric syndrome (PANS) is defined by an acute onset of obsessive-compulsive disorder and/or eating restrictions and at least two other severe neuropsychiatric symptoms. The condition is suspected to have an immune-mediated pathophysiology, but reliable biomarkers have not been identified. Methods We hypothesised that PANS, like narcolepsy, might have a human leucocyte antigen (HLA) association, as found in 95% of children developing narcolepsy after H1N1 immunisation. Low resolution genotyping of the MHC class II antigens HLA-DRB1 and HLA-DQB1 was performed using two different PCR-based methods. In addition, parents were interviewed regarding a detailed family history of autoimmune diseases in first-degree relatives. A total of 18 children, aged 5-14 (mean 8.2) years at onset of PANS met symptom criteria. Results No evident association between PANS and the specific HLA alleles examined was observed. In first-degree relatives of 10 of the 18 children, an autoimmune disease had been diagnosed, and three of the 18 children themselves had an autoimmune disease. Conclusion No HLA allele association such as seen in children with narcolepsy after H1N1 immunisation could be confirmed in this group of children with PANS. However, more than half the group had a first-degree relative with a diagnosed autoimmune disease.

  • Co-existing disorders in ADHD -- implications for diagnosis and intervention.
  • 2004
  • In: European Child & Adolescent Psychiatry. - : Springer Science and Business Media LLC. - 1018-8827 .- 1435-165X. ; 13 Suppl 1
  • Journal article (peer-reviewed)abstract
    • BACKGROUND: It is only recently that "comorbidity" in ADHD has come to the forefront as one of the most important aspects of the disorder. It is agreed that, often, these problems are at least as important as ADHD in contributing to the longer term outcome in the individual child. OBJECTIVE: To provide the reader with basic information about clinics and treatment of "comorbidity" in ADHD. METHOD: Review of the empirically based literature. RESULTS: ADHD exists in a surprisingly high frequency together with a broad range of child neuropsychiatric disorders. This is accompanied with many still unresolved treatment problems. CONCLUSION: It would not be appropriate to develop ADHD-services where clinicians would only have expertise in ADHD as such. Anyone working with children, adolescents and adults with ADHD would need to have training in general neuropsychiatry. Further research in this field is urgently needed.

  • Paediatric Acute-onset Neuropsychiatric Syndrome (PANS) and intravenous immunoglobulin (IVIG): comprehensive open-label trial in ten children
  • 2022
  • In: Bmc Psychiatry. - : Springer Science and Business Media LLC. - 1471-244X. ; 22:1
  • Journal article (peer-reviewed)abstract
    • Background Treatment with intravenous immunoglobulin (IVIG) in children with Paediatric Acute-onset Neuropsychiatric Syndrome (PANS) has for many years been used on clinical indications, but the research evidence for its efficacy is insufficient. Methods Open-label prospective in-depth trial including ten children (median age 10.3 years) with PANS, who received IVIG treatment 2 g/kg monthly for three months. Primary outcomes were changes in symptom severity and impairment from baseline to first and second follow-up visits one month after first and one month after third treatment, using three investigator-rated scales: Paediatric Acute Neuropsychiatric Symptom (PANS) scale, Clinical Global Impression - Severity and Improvement (CGI-S and CGI-I) scales. Secondary outcomes reported here were changes in Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) scores, and side effects. Results All ten children received three treatments at one-month intervals according to study plan. From baseline to second follow-up marked reductions were seen in mean total PANS scale scores (p = .005), and CGI-S scores (p = .004). CGI-I ratings showed much to very much global improvement (mean CGI-I 1.8). Nine children had clinical response defined as > 30% reduction in PANS Scale scores. Improvements were also noted for CY-BOCS scores (p = .005), and in school attendance. Three children suffered moderate to severe temporary side effects after the first treatment, and the remaining seven had mild to moderate side effects. Side effects were much less severe after second and third treatments. Conclusions Considerable and pervasive improvements in symptoms and clinical impairments were seen in these ten children after three monthly IVIG treatments. Moderate to severe transient side effects occurred in three cases.

  • Retrospective evaluation of ophthalmological and neurological outcomes for infants born before 24 weeks gestational age in a Swedish cohort
  • 2022
  • In: Bmj Open. - : BMJ. - 2044-6055. ; 12:8
  • Journal article (peer-reviewed)abstract
    • Objectives To retrospectively evaluate ophthalmological and neurological outcomes in a Swedish cohort of infants born before 24 weeks gestational age (GA) and explore risk factors for visual impairment. Setting Eye and paediatric clinics in Sweden. Participants Infants screened for retinopathy of prematurity (ROP) (n=399), born before 24 weeks GA, 2007-2018. Cases were excluded if ophthalmological follow-up records could not be traced. Primary and secondary outcome measures Primary outcomes were ophthalmological, including visual acuity (VA), refractive error, strabismus, nystagmus and cerebral visual impairment (CVI). Secondary outcomes comprised neonatal and neurological morbidities. Data were retrospectively retrieved from medical records. Results The 355 assessed children had a median GA of 23 weeks and 2 days and a median birth weight of 565 g. At the last available ophthalmological examination, the median age was 4.8 years (range 0.5-13.2 years). Nystagmus was recorded in 21.1%, strabismus in 34.8%, and 51.0% wore spectacles. Seventy-three of 333 (21.9%) were visually impaired, defined as being referred to a low vision clinic and/or having a VA less than 20/60 at 3.5 years of age or older. ROP treatment was a significant risk factor for visual impairment (OR 2.244, p=0.003). Visually impaired children, compared with children without visual impairment, more often had neurological deficits such as intellectual disability 63.8% versus 33.3% (p<0.001), epilepsy 21.1% versus 7.5% (p=0.001) and autism spectrum disorders 32.8% versus 20.9% (p=0.043). Nine of the 355 children had been diagnosed with CVI. Conclusions Children born before 24 weeks GA frequently had visual impairment in association with neurological deficits. CVI was rarely diagnosed. A multidisciplinary approach for the evaluation and habilitation of these vulnerable infants is warranted. National follow-up guidelines need to be developed and implemented.

  • Efficacy and safety of extended-release guanfacine hydrochloride in children and adolescents with attention-deficit/hyperactivity disorder: A randomized, controlled, Phase III trial
  • 2014
  • In: European Neuropsychopharmacology. - : Elsevier BV. - 0924-977X. ; 24:12, s. 1861-72
  • Journal article (peer-reviewed)abstract
    • Abstract: Guanfacine extended-release (GXR), a selective α2A-adrenergic agonist, is a non-stimulant treatment for attention-deficit/hyperactivity disorder (ADHD). This study assessed the efficacy (symptoms and function) and safety of dose-optimized GXR compared with placebo in children and adolescents with ADHD. An atomoxetine (ATX) arm was included to provide reference data against placebo. Patients (6-17 years) were randomized at baseline to dose-optimized GXR (0.05 mg/kg/day- 0.12 mg/kg/day: 6-12 years: 1-4 mg/day; 13-17 years: 1-7 mg/day), ATX (10-100 mg/day) or placebo for 4 or 7 weeks. The primary efficacy measure was change from baseline in ADHD Rating Scale version IV (ADHD-RS-IV). Key secondary measures were Clinical Global Impressions-Improvement (CGI-I) and the Weiss Functional Impairment Rating Scale-Parent Report (WFIRS-P; learning and school, and family domains). Safety assessments included treatment-emergent adverse events (TEAEs), electrocardiograms and vital signs. A total of 272 (80.5%) patients from Europe, the USA and Canada completed the study. Significant differences were observed in least squares mean change from baseline in ADHD-RS-IV total score (placebo-adjusted differences) (GXR: [−8.9, p<0.001]; ATX: [−3.8, p<0.05]), the difference from placebo in the percentage of patients showing improvement (1 ['very much improved'] or 2 ['much improved']) for CGI-I (GXR: [23.7, p<0.001]; ATX: [12.1 p<0.05]), WFIRS-P learning and school domain (GXR: [−0.22, p<0.01]; ATX: [−0.16, p<0.05]) and family domain (GXR: [−0.21, p<0.01]; ATX: [−0.09, p=0.242]). Most common TEAEs for GXR were somnolence, headache and fatigue; 70.1% of GXR subjects reported mild-to-moderate TEAEs. GXR was effective and well tolerated in children and adolescents with ADHD.

  • A randomized controlled trial of a new intervention in early symptomatic syndromes eliciting neurodevelopmental clinical examinations: PR-ESSENCE
  • 2021
  • In: European Child & Adolescent Psychiatry. - : Springer Science and Business Media LLC. - 1018-8827 .- 1435-165X. ; 32:1, s. 63-74
  • Journal article (peer-reviewed)abstract
    • The need for effective intervention programs for youth with neurodevelopmental problems (ESSENCE) and challenging behaviour is great. This study examines Problem Resolution in ESSENCE (PR-ESSENCE), a newly developed model in which children and parents develop mutual problem resolution strategies. Ten-week randomized controlled trial of PR-ESSENCE for children and adolescents aged 5-18 years, compared to treatment as usual. Outcomes were assessed at baseline and randomized period endpoint. Primary outcome was the Clinical Global Impression-Improvement scale (CGI-I) rated by blinded assessors. Secondary outcomes were rated by parents-SNAP-IV, Eyberg Child Behavior Inventory (ECBI), Relationship Problems Questionnaire, Family Burden of Illness Module, and children-Beck Youth Inventories (BYI). ClinicalTrials.gov identifier: NCT03780413. The study enrolled 108 participants (active n = 72; controls n = 36, randomized 2:1), of whom 95 completed the randomized period. No clinically significant group differences were found in baseline characteristics. More than half had autism and 80% had ADD or ADHD. Large treatment effects were seen on CGI-I (ITT analysis, Effect Size 1.48). Treatment responders, much/very much improved on CGI-I, were 51.4% in active group and 5.6% of controls. Effect sizes were medium to large in parent ratings on SNAP-IV (ODD and ADHD symptoms), ECBI (behaviour problems), and in BYI child self-ratings of disruptive behaviour. PR-ESSENCE treatment improved global symptoms and functioning (CGI-I), behaviour problems, ADHD and ODD symptoms, and disruptive behaviour. Treatment effects were at least equivalent to those in previous studies of well-established Parent Management Training and Collaborative Problem Solving programs.

  • Anti-inflammatory, antibacterial and immunomodulatory treatment in children with symptoms corresponding to the research condition PANS (Pediatric Acute-onset Neuropsychiatric Syndrome): A systematic review
  • 2021
  • In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 16:7
  • Journal article (peer-reviewed)abstract
    • Objective To assess effects of treatment against a hypothesized neuroinflammation in children with symptoms corresponding to the research condition Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) which is not included in current diagnostic systems. Methods Systematic literature searches were performed (1998 to June 2020) in PubMed, Embase, the Cochrane Library, CINAHL, PsycInfo, and HTA databases. Inclusion criteria: patients (P) were children (< 18 years) with PANS; intervention (I)/comparison (C) was use of, versus no use of, anti-inflammatory, antibacterial or immunomodulating treatments; outcomes (O) were health-related quality of life (HRQL), level of functioning, symptom change, and complications. Results Four randomised controlled trials (RCTs) and three non-RCTs, including 23 to 98 patients, fulfilled the PICO. HRQL was not investigated in any study. Regarding level of functioning, two RCTs investigated antibiotics (penicillin V, azithromycin) and one RCT investigated immunomodulating treatments (intravenous immunoglobulins (IVIG), plasma exchange). Regarding symptoms, two non-RCTs investigated anti-inflammatory treatment (cyclooxygenase (COX) inhibitors, corticosteroids), two RCTs and one non-RCT investigated antibiotics (penicillin V, azithromycin), and two RCTs investigated immunomodulating treatments (IVIG, plasma exchange). Complications, reported in five studies, were consistent with those listed in the summary of products characteristics (SPC). All studies were assessed to have some or major problems regarding directness, the absence of an established diagnosis contributing to clinical diversity in the studied populations. All studies were assessed to have major risk of bias, including selection and detection biases. Due to clinical and methodological diversity, meta-analyses were not performed. Conclusion This systematic review reveals very low certainty of evidence of beneficial effects, and moderate certainty of evidence of adverse effects, of anti-inflammatory, antibacterial or immunomodulating treatments in patients with symptoms corresponding to the research condition PANS. Available evidence neither supports nor excludes potential beneficial effects, but supports that such treatment can result in adverse effects.

  • Attention-deficit/hyperactivity disorder with oppositional defiant disorder in Swedish children - an open study of collaborative problem solving.
  • 2012
  • In: Acta Paediatrica. - : Wiley. - 0803-5253. ; 101:6, s. 624-630
  • Journal article (peer-reviewed)abstract
    • Aim: To evaluate Collaborative Problem Solving (CPS) in Swedish 6-13-year-old children with attention-deficit/hyperactivity disorder and oppositional defiant disorder. Methods: Seventeen families completed 6-10 sessions of CPS training. Primary outcome measures were SNAP-IV (ADHD and ODD scores) and Clinical Global Impression - Improvement (CGI-I) scores at baseline, post-intervention and 6 months later. Secondary outcome measures were the Conners'-10-item scale and the Family Burden of Illness Module (FBIM). Results: All 17 participants completed the intervention. The whole group had significant reductions in SNAP-IV ODD, ADHD, total Conners' and FBIM scores, both post-intervention and at 6-month-follow-up. Eight of the children, although significantly improved on ODD scores and the Conners' emotional lability subscale at post-intervention, had almost no improvement in hyperactivity/impulsivity. Post-intervention, this group received stimulant medication for their ADHD. At post-intervention CGI-I scores of much improved or very much improved were reached by 53% (9/17) of all at post-intervention, and by 81% (13/16) at 6-month follow-up. Conclusion: CPS significantly reduced ODD, ADHD and emotional lability symptoms. A subgroup improved in their ADHD symptoms only after adding stimulant medication.

  • Fatty acids in ADHD: plasma profiles in a placebo-controlled study of Omega 3/6 fatty acids in children and adolescents.
  • 2012
  • In: Attention Deficit and Hyperactivity Disorders. - : Springer Science and Business Media LLC. - 1866-6116 .- 1866-6647. ; 4:4, s. 199-204
  • Journal article (peer-reviewed)abstract
    • The aim of this study was to assess baseline levels and changes in plasma fatty acid profiles in children and adolescents with ADHD, in a placebo-controlled study with Omega 3/6 supplementation, and to compare with treatment response. Seventy-five children and adolescents aged 8-18years with DSM-IV ADHD were randomized to 3months of Omega 3/6 (Equazen eye q) or placebo, followed by 3months of open phase Omega 3/6 for all. n-3, n-6, n-6/n-3 ratio, EPA and DHA in plasma were measured at baseline, 3 and 6months. Subjects with more than 25% reduction in ADHD symptoms were classified as responders. At baseline, no significant differences in mean fatty acid levels were seen across active/placebo groups or responder/non-responder groups. The 0-3month changes in all parameters were significantly greater in the active group (p<0.01). Compared to non-responders, the 6-month responders had significantly greater n-3 increase at 3months and decrease in n-6/n-3 ratio at 3 and 6months (p<0.05). Omega 3/6 supplementation had a clear impact on fatty acid composition of plasma phosphatidyl choline in active versus placebo group, and the fatty acid changes appear to be associated with treatment response. The most pronounced and long-lasting changes for treatment responders compared to non-responders were in the n-6/n-3 ratio.

  • Long-term medication for ADHD and development of cognitive functions in children and adolescents
  • 2021
  • In: Journal of Psychiatric Research. - : Elsevier BV. - 0022-3956. ; 142, s. 204-209
  • Journal article (peer-reviewed)abstract
    • Objective: Long-term effects of ADHD medication on cognitive functions are not well known. This study investigates development of cognitive functions and ADHD symptoms on well-controlled medication for 1 year in children and adolescents. Study design: This study is part of an ongoing open uncontrolled trial of long-term medication for ADHD in children and adolescents aged 6-18 years with any form of ADHD, and frequently comorbid autism spectrum disorder (ASD, 29%) or autistic traits (24%). Other comorbidities were oppositional defiant disorder, dyslexia/ language disorder, borderline intellectual functioning, developmental coordination disorder. This analysis includes 87 participants (61 boys, 26 girls) who completed Wechsler tests at baseline and after 12 months. ADHD symptoms were investigator-rated on the ADHD Rating Scale-IV at the same time points. Results: The whole group of children and adolescents showed significant improvements in Wechsler Full Scale IQ (FSIQ, mean at baseline 92.6, at 12 months 97.95), and on the Index Scales Verbal Comprehension, Working Memory and Processing Speed, after one year of well-controlled ADHD medication. Comorbid dyslexia/language impairment predicted a larger rise in FSIQ, but not gender, ADHD presentation or comorbid ASD. Robust improvements in ADHD symptoms were observed (mean ADHD-Rating Scale score at baseline 34.6, and at 12 months 18.3). Conclusions: Cognitive test scores and ADHD symptoms were improved on well-controlled medication for 1 year in children and adolescents with ADHD, autism and other comorbidities. The main study limitation is the open uncontrolled trial design.

  • Long-term medication for ADHD (LMA) trial: 2-year prospective observational study in children and adolescents. Core symptoms, daily functioning, and comorbidity outcomes
  • 2024
  • In: European Archives of Psychiatry and Clinical Neuroscience. - 0940-1334. ; 274:4, s. 879-890
  • Journal article (peer-reviewed)abstract
    • More knowledge is needed about long-term ADHD medication and symptom, daily functioning, comorbidity, and tolerability outcomes. This "Long-term Medication for ADHD (LMA) trial" was a prospective observational 2-year trial in children and adolescents aged 6-18 years (extension of 1-year trial). Participants met criteria for DSM-5 ADHD (inattentive or combined), with complex comorbidities; autism spectrum disorder (31%), autistic traits (24%), oppositional symptoms (59%), anxiety (32%), dyslexia/language disorder (16%), borderline intellectual functioning (17%). Medication was individually tailored and followed-up at clinical visits (1, 2, 3, 6, 12, 18, 24 months). Primary outcome: Clinical Global Impression-Severity and Improvement scales (CGI-S, CGI-I). Secondary outcomes: Investigator-rated ADHD-Rating Scale, Weiss Functional Impairment Rating Scale-Parent report (WFIRS-P; Family, School Learning and Behavior, Life Skills, Self-Concept, Social Activities, and Risky Activities domains), comorbidity symptoms and adverse events (AEs). One hundred twenty-eight participants were enrolled (1-year trial only n = 27, LMA trial n = 101). Of these 29 (23%) discontinued, mainly due to AEs (n = 7), moving (n = 7), or no longer needing medication (n = 6). Main AEs were poor appetite, low mood, anxiety, irritability, fatigue. Improvements from baseline to 2 years were large in CGI-S (effect size (ES) 2.28), ADHD-RS (ES 2.06), and moderate to large in WFIRS-P (ES total 0.73, learning 0.4, family 0.67). Overall, the trial showed robust and sustained improvements in ADHD symptom severity and daily functioning over a period of 2 years of ADHD medication in children and adolescents with ADHD and complex comorbidities. Most AEs were mild. Comorbidity symptoms were improved after 1 year, particularly oppositional symptoms, depression, and anxiety.

    • Summary Objective: Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) is characterized by an acute onset of obsessive compulsive disorder, combined with at least two other neuropsychiatric symptoms with acute onset. Diagnostic criteria also require that no specific medical etiology is identified. Although there are no verified etiological biomarkers, PANS is assumed to be a neuroinflammatory disorder with a possible autoimmune etiology. Neurochemical markers such as neurofilament light (NfL, a neuronal injury marker) and glial fibrillary acidic protein (GFAP, an astrocytic activation marker) have not been published for this patient group. Method: Blood samples from 17 children meeting diagnostic criteria for PANS, after assessment at a child neuropsychiatry clinic were analysed for serum concentrations of NfL and GFAP. Ten age-matched children without any neurological or psychiatric disorder served as a comparison group. Results: No difference was found in mean NfL and mean GFAP serum concentrations between children with PANS and controls. Conclusion: Neuronal injury and astrocyte activation do not seem to be a major event in PANS. The study group was small, and even if findings may be reassuring for parents and patients, they should be interpreted with caution and verified in larger cohort and possibly with other markers in both serum and CSF.

  • Non-stimulant interventions in ADHD
  • 2014
  • Doctoral thesis (other academic/artistic)abstract
    • Aim: The overall aim of the thesis was to study alternative non-stimulant treatments for Attention Deficit Hyperactivity Disorder (ADHD) in children, adolescents and adults. Method: The thesis includes four studies referring to three different treatment trials. Study 1: Randomized double-blind placebo-controlled trial of Omega 3/6 fatty acids (Equazen eyeq) treatment of ADHD in children and adolescents. Study 2: Changes in plasma fatty acid profiles in the Omega 3/6 trial, and comparison with treatment response. Study 3: One-year trial of efficacy and safety of the non-stimulant medication atomoxetine in adults with ADHD. Study 4: Study of the effectiveness of the cognitive training method “Collaborative Problem Solving” in children with ADHD and Oppositional Defiant Disorder (ODD). Results: The overall group results of Study 1 were negative, but clinical response was seen in subgroups such as those with ADHD inattentive subtype, Developmental Coordination Disorder (DCD), and reading-writing disorder. Study 2 findings suggested that clinical response to Omega 3/6 was associated with plasma fatty acid changes, especially with reduction of the n-6/n-3 ratio. Study 3 showed a moderate effectiveness of atomoxetine after 10 weeks in adults with ADHD, but the longer-term compliance to treatment was poor. In study 4 CPS showed promise in reducing problem behaviours in children with ADHD and ODD, and children with severe ADHD symptoms may be improved by combining CPS and ADHD medication. Conclusions: The trials of non-stimulant treatments included in this thesis showed some promising results and suggested directions for future research and study design.

  • Omega 3/6 fatty acids for reading in children: a randomized, double-blind, placebo-controlled trial in 9-year-old mainstream schoolchildren in Sweden
  • 2017
  • In: Journal of Child Psychology and Psychiatry and Allied Disciplines. - : Wiley. - 0021-9630 .- 1469-7610. ; 58:1, s. 83-93
  • Journal article (peer-reviewed)abstract
    • Background Previous research has shown positive effects of Omega 3/6 fatty acids in children with inattention and reading difficulties. We aimed to investigate if Omega 3/6 improved reading ability in mainstream schoolchildren. Methods We performed a 3-month parallel, randomized, double-blind, placebo-controlled trial followed by 3-month active treatment for all subjects. Mainstream schoolchildren aged 9–10 years were randomized 1:1 to receive three Omega 3/6 capsules twice daily or identical placebo. Assessments were made at baseline, 3 months, and 6 months. The primary outcome measure was the Logos test battery for evaluating reading abilities. The trial is registered with ClinicalTrials.gov, number NCT02557477. Results The study enrolled 154 children (active n = 78; placebo n = 76), of whom 122 completed the first 3 months (active n = 64; placebo n = 58) and 105 completed the whole study (active/active n = 55; placebo/active n = 50). Outcomes were assessed by per protocol (PP) and intention-to-treat (ITT) analyses. Active treatment was superior to placebo at 3 months for improvement in phonologic decoding time (PP active/placebo difference −0.16; 95% CI −0.03, −0.29; effect size (ES) .44; p = .005; and ITT ES .37; p = .036), in visual analysis time (PP active/placebo difference −0.19; 95% CI −0.05, −0.33; ES .49; p = .013; and ITT ES .40; p = .01), and for boys in phonologic decoding time (PP −0.22; 95% CI −0.03, −0.41; ES .62; p = .004). Children with ADHD-RS scores above the median showed treatment benefits in visual analysis time (PP ES .8, p = .009), reading speed per word (PP ES .61, p = .008), and phonologic decoding time per word (PP ES .85, p = .006). Adverse events were rare and mild, mainly stomach pain/diarrhea (active n = 9, placebo n = 2). Conclusions Compared with placebo, 3 months of Omega 3/6 treatment improved reading ability – specifically the clinically relevant ‘phonologic decoding time’ and ‘visual analysis time’ – in mainstream schoolchildren. In particular, children with attention problems showed treatment benefits.

    • Objective: The aim of the study was to assess omega 3/6 fatty acids (eye q) in attention deficit hyperactivity disorder (ADHD). Method: The study included a randomized, 3-month, omega 3/6 placebo-controlled, one-way crossover trial with 75 children and adolescents (8–18 years), followed by 3 months with omega 3/6 for all. Investigator-rated ADHD Rating Scale–IV and Clinical Global Impression (CGI) scale were outcome measures. Results: A majority did not respond to omega 3/6 treatment. However, a subgroup of 26% responded with more than 25% reduction of ADHD symptoms and a drop of CGI scores to the near-normal range. After 6 months, 47% of all showed such improvement. Responders tended to have ADHD inattentive subtype and comorbid neurodevelopmental disorders. Conclusion: A subgroup of children and adolescents with ADHD, characterized by inattention and associated neurodevelopmental disorders, treated with omega 3/6 fatty acids for 6 months responded with meaningful reduction of ADHD symptoms.

  • Paediatric acute-onset neuropsychiatric syndrome in children and adolescents: an observational cohort study.
  • 2019
  • In: The Lancet. Child & adolescent health. - 2352-4650. ; 3:3, s. 175-180
  • Journal article (peer-reviewed)abstract
    • Paediatric acute-onset neuropsychiatric syndrome (PANS) is a newly defined symptom-based condition that mainly occurs in children and adolescents. Few studies have described the clinical characteristics of the syndrome.We clinically assessed and reviewed the medical histories of children and adolescents (aged 4-14 years) with suspected PANS who were referred to a specialist clinic in Gothenburg, Sweden, by local paediatricians and child psychiatrists. We scored severity of symptoms and impairment retrospectively for the timepoint with the most severe symptoms using the PANS scale.Of 41 patients (37 referred and four visited upon parents' request), 23 (ten girls and 13 boys) met PANS diagnostic criteria. Mean age at PANS onset was 8·5 years (SD 3·37). 11 (48%) patients had a family history of developmental or neuropsychiatric disorders in a first-degree relative and 11 (48%) had a family history of autoimmune or inflammatory diseases in a first-degree relative. 17 (74%) patients had been previously diagnosed with a developmental disorder (n=5) or had symptoms indicative of developmental problems (n=12). A verified or suspected infection was temporally related to PANS onset in all patients; the infection was bacterial in ten (43%) patients (eight had streptococcal infection and two an infection caused by other bacteria) and viral in 13 (57%) patients. All patients had a relapsing-remitting course of illness. The mean PANS scale symptom score was 46 (SD 3·67) and the mean impairment score was 45 (2·74). Antibiotic treatment was reported as beneficial by the parents of 12 (63%) of the 19 children who received antibiotics.Our PANS cohort had severe, acute-onset, complex neuropsychiatric symptoms, a relapsing-remitting symptom course, and possible infectious triggers. Further research into the cause of, and appropriate treatment for, PANS is warranted.Swedish Brain Foundation.

  • Evaluation of C4 gene copy number in Pediatric Acute Neuropsychiatric Syndrome
  • 2023
  • In: Developmental Neuroscience. - 0378-5866. ; 45:6, s. 315-324
  • Journal article (peer-reviewed)abstract
    • Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) is an abrupt-onset neuropsychiatric disorder. PANS patients have an increased prevalence of co-morbid autoimmune illness, most commonly arthritis. In addition, an estimated one-third of PANS patients present with low serum C4 protein, suggesting decreased production or increased consumption of C4 protein. To test the possibility that copy number (CN) variation contributes to risk of PANS illness, we compared mean total C4A and total C4B CN in ethnically-matched subjects from PANS DNA samples and controls (192 cases and 182 controls). Longitudinal data from the Stanford PANS cohort (n = 121) was used to assess whether the time to Juvenile Idiopathic Arthritis (JIA) or Autoimmune Disease (AI) onset was a function of total C4A or C4B. Lastly, we performed several hypothesis-generating analyses to explore the correlation between individual C4 gene variants, sex, specific genotypes and age of PANS onset. Although the mean total C4A or C4B CN did not differ in PANS compared to controls, PANS patients with low C4B CN were at increased risk for subsequent JIA diagnosis (Hazard Ratio = 2 7, p-value = 0 004). We also observed a possible increase in risk for AI in PANS patients and a possible correlation between lower C4B and PANS age of onset. An association between rheumatoid arthritis and low C4B CN has been reported previously. However, patients with PANS develop different types of JIA: enthesitis-related arthritis, spondyloarthritis and psoriatic arthritis. This suggests that C4B plays a role that spans these arthritis types.

  • Computerized training of working memory in children with ADHD--a randomized, controlled trial.
  • 2005
  • In: Journal of the American Academy of Child and Adolescent Psychiatry. - : Elsevier BV. - 0890-8567 .- 1527-5418. ; 44:2, s. 177-186
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE: Deficits in executive functioning, including working memory (WM) deficits, have been suggested to be important in attention-deficit/hyperactivity disorder (ADHD). During 2002 to 2003, the authors conducted a multicenter, randomized, controlled, double-blind trial to investigate the effect of improving WM by computerized, systematic practice of WM tasks. METHOD: Included in the trial were 53 children with ADHD (9 girls; 15 of 53 inattentive subtype), aged 7 to 12 years, without stimulant medication. The compliance criterion (>20 days of training) was met by 44 subjects, 42 of whom were also evaluated at follow-up 3 months later. Participants were randomly assigned to use either the treatment computer program for training WM or a comparison program. The main outcome measure was the span-board task, a visuospatial WM task that was not part of the training program. RESULTS: For the span-board task, there was a significant treatment effect both post-intervention and at follow-up. In addition, there were significant effects for secondary outcome tasks measuring verbal WM, response inhibition, and complex reasoning. Parent ratings showed significant reduction in symptoms of inattention and hyperactivity/impulsivity, both post-intervention and at follow-up. CONCLUSIONS: This study shows that WM can be improved by training in children with ADHD. This training also improved response inhibition and reasoning and resulted in a reduction of the parent-rated inattentive symptoms of ADHD.

  • Blood pressure and anthropometry in children treated with stimulants: a longitudinal cohort study with an individual approach.
  • 2017
  • In: Neuropsychiatric disease and treatment. - 1176-6328. ; 13, s. 499-506
  • Journal article (peer-reviewed)abstract
    • Knowledge about the long-term effects on blood pressure (BP) and body mass index (BMI) when treating young patients for attention-deficit/hyperactivity disorder (AD/HD) with stimulants is limited. Most of the studies have reported mean and not individual values for anthropometrics and BP in treatment with stimulants. This seems to be the first study of changes based on the analyses of individual data measured over time.Seventy young patients (aged 8-18 years) diagnosed with AD/HD and responding well to treatment with stimulants were followed for a mean period of 3 years and 3 months. BP, heart rate, height, weight, and BMI were transformed to standard deviations or z-scores from before treatment to the last registered visit.The mean dose of methylphenidate was 0.95 mg/kg. The mean increase of systolic and diastolic BP was 0.4 z-score and 0.1 z-score, respectively. The systolic BP was associated with BMI; a higher BMI at baseline increased the risk for an increase in systolic BP. Ten percent of the total group had a weight at follow-up of <-1.5 standard deviation (SD) and 12% had a height of <-1.5 SD. Mean height at follow-up was -0.2 SD, but 40% had a reduced height of at least 0.5 SD during the treatment period. BMI on a group level was reduced from +0.8 SD to +0.3 SD. Of the 19 patients with a BMI >+1.5 SD at baseline, 50% had a significantly reduced BMI.Consequences of stimulant treatment must be evaluated individually. Besides significant effects on core AD/HD symptoms, some patients have lower BMI and BP and some increase/maintain their BMI and/or increase their systolic BP. The risk of reduced height trajectory needs further research.

  • Attention-deficit/hyperactivity disorder with developmental coordination disorder: 24-year follow-up of a population-based sample
  • 2021
  • In: BMC Psychiatry. - : Springer Science and Business Media LLC. - 1471-244X. ; 21:1
  • Journal article (peer-reviewed)abstract
    • BackgroundAlthough the body of research concerning neurodevelopmental disorders is vast, there is a scarcity of longitudinal studies beyond late adolescence, and of studies taking co-existing disorders into account. The present study aimed to investigate outcome in adulthood for children with attention-deficit/hyperactivity disorder (ADHD) combined with developmental coordination disorder (DCD) diagnosed at 6.6years of age.MethodsOut of a screening-based population cohort of 589 individuals, 62 (10 female) diagnosed with ADHD+DCD at mean age 6.6years naive to stimulant treatment were followed into adulthood through national registries. Results were compared to a screen- and assessment negative population matched group from the same cohort (PM group, n=51) and a registry-matched (RM group, n=410) group of the same county and age.ResultsAt 30 to 31years of age, five deaths had occurred; one in the ADHD+DCD group and two each in the comparison groups. In time to event analyses of the composite outcome of any psychiatric disorder, psychotropic prescription, sick pension or criminal sentence, events occurred at a significantly higher rate in the ADHD+DCD group (p=0.0032, vs PM group p=0.0115, vs RM group p=0.0054). The ADHD+DCD group had significantly higher rates of psychiatric diagnoses, prescriptions of psychoactive medications and occurrence of sick pension than both comparison groups. Further, the ADHD+DCD group had significantly lower educational attainment compared to both comparison groups, more years with unemployment, and overall higher welfare recipiency. Rates of pain diagnoses and analgesic prescriptions did not separate the groups.ConclusionADHD+DCD entailed a less favorable outcome in adulthood compared to a non-clinical comparison group and a registry-matched population. Neurodevelopmental disorder diagnosed upon school entry is of prognostic utility with respect to function in adulthood, and warrants early identification and management.

  • 2022
  • In: Bmj Open. - : BMJ. - 2044-6055. ; 12:3
  • Journal article (peer-reviewed)abstract
    • Objective Investigate predictors of adverse outcome in children with and without attention-deficit/hyperactivity disorder (ADHD) combined with developmental coordination disorder (DCD) at 6 years of age. Design Prospective population-based cohort study. Setting Western Sweden. Participants From a screening-based population cohort of 589 individuals, 62 (11 female) diagnosed with ADHD+DCD at mean age 6.6 years, and a comparison group of 51 population-matched (10 female) children were followed prospectively. Outcome measures Drawn from a clinical reassessment at age 9 years of 110 of the 113 individuals, neuropsychiatric symptoms, continuous performance test results and measures of motor function were used as predictors of outcome in linear regression models. Participants were followed in national registers up to 30-31 years of age for outcomes in adulthood. Predictors were regressed onto an adverse outcome score (range 0-7) comprising seven binary endpoints, and when applicable onto each continuous outcome separately (low educational attainment, low occupation level, psychiatric disorder, psychotropic medication prescription, sick pension, high dependence on social benefits and criminal conviction). Results Of the 110 individuals, 3 had died. In univariable regression onto the adverse outcome score, the strongest predictors at age 9 years were symptoms of conduct disorder, oppositional defiant disorder, ADHD and motor dysfunction, with an R-2 around 25%, followed by autistic traits (R-2=15%) and depressive symptoms (R-2=8%). Combining these six strongest predictors in a multivariable model yielded an adjusted R-2=38%. Subgroup analyses were similar, except for a strong association of autistic traits with the adverse outcome score in females (n=20, R-2=50%). Conclusion Several neurodevelopmental symptoms, including ADHD severity at age 9 years, accounted for a considerable amount of the variance in terms of adulthood adverse outcome. Broad neurodevelopmental profiling irrespective of diagnostic thresholds should inform research and clinical practice. The study highlights the importance of considering associated comorbidities and problems in ADHD.

  • In: Acta Paediatrica. - 0803-5253. ; 113:3, s. 506-516
  • Journal article (peer-reviewed)abstract
    • Aim: Assessing rates of neurodevelopmental problems (NDPs) in 11-year-old children and possible association with other health complaints and school performance.Methods: In-school study of 11-year-old children as an add-on assessment to the 4th grade regular health check-up, comprising a structured physical neurodevelopmental examination, neuropsychological assessment, behavioural ratings, maternal interview, review of medical records and academic achievements.Results: Out of 348 children recruited from eight schools, 223 (64%) participated. Any physical condition was found in 102/222 (46%), most commonly atopy (18%). One in five had a BMI z-score >2 standard deviations over the reference mean. One or more NDP was found in 86/221 (40%) children. The number of failed national tests correlated positively with NDP severity rated with the clinical global impression severity instrument (Spearman's r = 0.41, p < 0.001). The majority of participants with failed national tests, also had co-occurring health complaints (>= 2 of: stomach or extremity ache, headache, difficulties sleeping, internalising symptoms or obesity) and NDPs.Conclusion: Health complaints, physical conditions and NDPs are very common in 11-year-old children and warrant adequately staffed, thoroughly equipped school healthcare services.

  • The ESSENCE-Questionnaire for Neurodevelopmental Problems – A Swedish School-Based Validation Study in 11-Year-Old Children
  • 2022
  • In: Neuropsychiatric Disease and Treatment. - 1178-2021. ; 18, s. 2055-2067
  • Journal article (peer-reviewed)abstract
    • Purpose: To determine the prevalence of parent-rated developmental concern using the ESSENCE-Q (Early Symptomatic Syndromes Eliciting Neurodevelopmental Clinical Examinations-Questionnaire, 12-items, score range 0–24) and to ascertain the predictive validity and optimal cutoff level of the instrument in a school-based sample of 11-year-old children. Methods: In a cross-sectional, school-based study, participants underwent a clinical assessment by a physician and a psychologist, teachers and parents completed the SDQ (Strength and Difficulties Questionnaire), medical health records and national tests were reviewed, and parents independently completed the ESSENCE-Q. In a case-conference outcomes were defined as a) the need for further clinical work-up due to suspected neurodevelopmental problems (NDPs) and b) degree of investigator-rated symptoms/ impairment from NDPs on the CGI-S (Clinical Global Impression-Severity instrument, range 1–7, 4–7 defined as clinically sympto-matic). Classification and optimal cutoffs of the ESSENCE-Q were determined using ROC (Receiver Operating Characteristic) analysis. Results: Out of 343 eligible children, 223 enrolled, of whom 173 (50% of all eligible) had a parent-rated ESSENCE-Q. At least one of the 12 possible concerns was reported by parents of 36% of participants. Overall, in 101 (57%) participants a work-up was warranted, and 64 (37%) were clinically symptomatic from NDPs. The AUC of the ESSENCE-Q in detecting need for work-up was 0.70 (95% confidence interval [CI] 0.63–0.77), and the AUC in detecting clinically symptomatic participants was 0.82 (95% CI 0.76–0.88). ESSENCE-Q ratings correlated positively with CGI-S scores (r=0.48, p<0.05). A cutoff of ≥3 had the highest accuracy (78%) with a negative predictive value of 82%. Ratings >6 conferred few false positives cases with positive likelihood ratios >10 and positive predictive values of 86% or more. Significance: This study of the ESSENCE-Q in 11-year-old children suggests it might be an acceptable instrument for screening of NDPs in children in middle school, optimally in conjunction with other methods.

  • 2022
  • In: Acta Paediatrica, International Journal of Paediatrics. - : Wiley. - 0803-5253 .- 1651-2227. ; 111:6, s. 1167-1175
  • Journal article (peer-reviewed)abstract
    • Aim: This study investigated childhood diagnoses in children born extremely preterm before 24 weeks of gestation. Methods: Diagnoses of neurodevelopmental disorders and selected somatic diagnoses were retrospectively retrieved from national Swedish registries for children born before 24 weeks from 2007 to 2018. Their individual medical files were also examined. Results: We studied 383 children born at a median of 23.3 (range 21.9–23.9) weeks, with a median birthweight of 565 (range 340–874) grams. Three-quarters (75%) had neurodevelopmental disorders, including speech disorders (52%), intellectual disabilities (40%), attention deficit hyperactivity disorder (30%), autism spectrum disorders (24%), visual impairment (22%), cerebral palsy (17%), epilepsy (10%) and hearing impairment (5%). More boys than girls born at 23 weeks had intellectual disabilities (45% vs. 27%, p < 0.01) and visual impairment (25% vs. 14%, p < 0.01). Just over half of the cohort (55%) received habilitation care. The majority (88%) had somatic diagnoses, including asthma (63%) and failure to thrive/short stature (39%). Conclusion: Most children born before 24 weeks had neurodevelopmental disorders and/or additional somatic diagnoses in childhood and were referred to habilitation services. Clinicians should be aware of the multiple health and developmental problems affecting these children. Resources are needed to identify their long-term support needs at an early stage.

    • Children born before 24 gestational weeks had high neonatal morbidity and a majority had one or more neurodevelopmental disorders in addition to somatic diagnoses in childhood. Active Swedish perinatal care of infants with gestational age <24 weeks has resulted in a survival rate of more than 50 percent. Resuscitation of these immature infants is controversial, and some countries offer comfort care only. In a retrospective review of medical files and registries of 399 Swedish infants born before 24 gestational weeks, a majority had severe prematurity-related neonatal diagnoses. In childhood (2-13 years), 75 percent had at least one neurodevelopmental disorder and 88 percent had one or more prematurity-related somatic diagnosis (permanent or transient) that was likely to affect their quality of life. Long-term consequences for surviving infants should be considered in general recommendations as well as in parental information.

  • Establishment of reference values for plasma neurofilament light based on healthy individuals aged 5-90 years
  • 2022
  • In: Brain Communications. - : Oxford University Press (OUP). - 2632-1297. ; 4:4
  • Journal article (peer-reviewed)abstract
    • The recent development of assays that accurately quantify neurofilament light, a neuronal cytoskeleton protein, in plasma has generated a vast literature supporting that it is a sensitive, dynamic, and robust biomarker of neuroaxonal damage. As a result, efforts are now made to introduce plasma neurofilament light into clinical routine practice, making it an easily accessible complement to its cerebrospinal fluid counterpart. An increasing literature supports the use of plasma neurofilament light in differentiating neurodegenerative diseases from their non-neurodegenerative mimics and suggests it is a valuable biomarker for the evaluation of the effect of putative disease-modifying treatments (e.g. in multiple sclerosis). More contexts of use will likely emerge over the coming years. However, to assist clinical interpretation of laboratory test values, it is crucial to establish normal reference intervals. In this study, we sought to derive reliable cut-offs by pooling quantified plasma neurofilament light in neurologically healthy participants (5-90 years) from eight cohorts. A strong relationship between age and plasma neurofilament light prompted us to define the following age-partitioned reference limits (upper 95(th) percentile in each age category): 5-17 years = 7 pg/mL; 18-50 years = 10 pg/mL; 51-60 years = 15 pg/mL; 61-70 years = 20 pg/mL; 70 + years = 35 pg/mL. The established reference limits across the lifespan will aid the introduction of plasma neurofilament light into clinical routine, and thereby contribute to diagnostics and disease-monitoring in neurological practice. Simren et al. report age-stratified cut-offs for plasma neurofilament light, based on a large material of healthy individuals across the ages 5-90 years. The findings will assist clinical implementation of plasma neurofilament light in clinical routine, by simplifying interpretation of concentrations across the lifespan as neurofilament light increases with age.

  • 2014
  • In: Journal of Disability and Oral Health. - 1470-8558. ; 15:4, s. 5-13
  • Journal article (peer-reviewed)abstract
    • Aim and objectives: The aim of this study was to describe the oral health and dental care for a group of children and adolescents diagnosed ADHD. Design: Patients with ADHD, referred to the Gothenburg Child Neuropsychiatric Clinic, were invited to participate in the study. Thirty-one individuals responded and underwent a clinical examination and the parents answered a questionnaire and an interview. Retrospective data from dental records concerning caries, cancelled/missed appointments, treatments without notations of anaesthetics, dental trauma, dental behaviour management problems and number of prophylactic treatments, were compiled. Results: A high prevalence of caries was found in all ages. The calculated risk of developing caries showed that 100% of this group had or will develop caries by the age of 19 years. Treatment without notations of local anaesthetics, behaviour management problems, missed appointments and cancellations were common. Visual plaque was found in a majority of the individuals (17/31) despite numerous occasions for prophylactic treatment. Dental traumatic injuries (20/31) were spread over different ages and several subjects had experienced more than one. Conclusions: In conclusion, this group of children with ADHD exhibited a high number of missed appointments, cancellations and a caries prevalence.

    • Attention deficit hyperactivity disorder (ADHD) is a common psychiatric condition characterized by age-inappropriate levels of inattention, hyperactivity-impulsiveness or a combination of these. The aim of this study was to analyze parental attitudes to and experience of dental care, oral hygiene and dietary habits in children/adolescents with ADHD. Twenty-six parents of 31 subjects, 20 boys and 11 girls, aged 5-19 years with ADHD registered at the Gothenburg Child Neuropsychiatric Clinic, were invited. The parents answered a questionnaire regarding different oral problems when visiting the Clinic of Pediatric Dentistry, Gothenburg, for an oral examination of their child. The parents felt the dental care at the Public Dental Service was good, but noted a lack of knowledge regarding child neuropsychiatry among the dental staff which may influence the dental treatment. Fifteen parents reported their children had experienced mouth pain and 15 reported their child had suffered from both discomfort and pain from local anesthesia. Thirteen of the children had a dental trauma and 12 parents reported pain in connection to the dental treatment. Pain related to filling therapy was stated by 11 parents. According to the parents, five children suffered from dental fear but 15 reported the child had a general fear. Pursuant to the parents, the beverage for dinner was mainly milk or water, while sweet drinks were more frequent when thirsty. Seventeen; parents reported their children had poor oral hygiene or could not manage to brush their teeth and 14 of the 31 children only brushed once a day or less. The results show that the parents experience a lack of child neuropsychiatric knowledge, care and patience from the dental staff, which may influence the treatment. Oral hygiene/tooth brushing is neglected and the frequent consumption of sugar is difficult for the parents to handle.

    • Neuropsychiatric and neurodevelopmental disorders are often associated with coordination problems. Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) constitutes a specific example of acute and complex symptomatology that includes difficulties with motor control. The present proof-of-concept study aimed at testing a new, bespoke tablet-based motor coordination test named SpaceSwipe, providing fine-grained measures that could be used to follow-up on symptoms evolution in PANS. This test enables computationally precise and objective metrics of motor coordination, taking into account both directional and spatial features continuously. We used SpaceSwipe to assess motor coordination in a group of children with PANS (n=12, assessed on in total of 40 occasions) and compared it against the motor coordination subtest from the Beery-Buktenica Developmental Test of Visual-Motor Integration (Beery VMI) 6th edition, traditionally used to follow-up symptomatology. Using a bivariate linear regression, we found that 33s of the directional offset from tracking a moving target in SpaceSwipe could predict the Beery VMI motor coordination (VMI MC) raw scores (mean absolute error: 1.75 points). Positive correlations between the predicted scores and the VMI MC scores were found for initial testing (radj=0.87) and for repeated testing (radj=0.79). With its short administration time and its close prediction to Beery VMI scores, this proof-of-concept study demonstrates the potential for SpaceSwipe as a patient-friendly tool for precise, objective assessment of motor coordination in children with neurodevelopmental or neuropsychiatric disorders.

  • Visuomotor tracking strategies in children: associations with neurodevelopmental symptoms
  • 2024
  • In: Experimental Brain Research. - 0014-4819 .- 1432-1106. ; 242:2, s. 337-353
  • Journal article (peer-reviewed)abstract
    • Children with neurodevelopmental disorders (NDDs) often display motor problems that may impact their daily lives. Studying specific motor characteristics related to spatiotemporal control may inform us about the mechanisms underlying their challenges. Fifty-eight children with varying neurodevelopmental symptoms load (median age: 5.6years, range: 2.7–12.5years) performed an interactive tablet-based tracking task. By investigating digit touch errors relative to the target’s movement direction, we found that a load of neurodevelopmental symptoms was associated with reduced performance in the tracking of abrupt alternating directions (zigzag) and overshooting the target. In contrast, reduced performance in children without neurodevelopmental symptoms was associated with lagging behind the target. Neurodevelopmental symptom load was also associated with reduced flexibility in correcting for lateral deviations in smooth tracking (spiral). Our findings suggest that neurodevelopmental symptoms are associated with difficulties in motor regulation related to inhibitory control and reduced flexibility, impacting motor control in NDDs.
