- Decreased information processing speed (mental slowing) is a known sequelae of many brain disorders, and can be assessed by continuous naming tasks. Functional imaging studies have shown that pause and articulation times in continuous speech are normally associated with different brain regions, but knowledge about such association in dementia is lacking. We therefore tested the hypothesis that perfusion deficits in Alzheimer's disease (AD) are not only associated with slower processing, but also with these speech measures. Using regional cerebral blood flow (rCBF) measurements during the performance of a continuous colour and form-naming task, we found that naming speed was substantially slower in AD patients than in controls. This slower naming was exclusively determined by an increase in mean pause time, and only to a limited extent by articulation time. The increased pause time was uniquely associated with temporo-parietal rCBF reductions of the patients, while articulation was not. By contrast, the rCBF of healthy elderly control subjects was consistently accompanied by substantially shorter articulation and pause times, although the naming measures were not statistically associated with rCBF. These findings suggest that pause time (in contrast to articulation time) may serve as a sensitive measure in the assessment of information processing speed deficits in dementia, by virtue of its close association with brain pathology.

- Previous publications have shown a high diagnostic sensitivity and specificity of three short clinical rating scales for Alzheimer's disease (AD), frontotemporal dementia (FTD), and vascular dementia (VaD) validated against neuropathological (NP) diagnoses. In this study, the aim was to perform an exploratory factor analysis of the items in these clinical rating scales. The study included 190 patients with postmortem diagnoses of AD (n = 74), VaD (n = 33), mixed AD/VaD (n = 31), or FTD (n = 52). The factor analysis produced three strong factors. Factor 1 contained items describing cerebrovascular disease, similar to the Hachinski Ischemic Score. Factor 2 enclosed major clinical characteristics of FTD, and factor 3 showed a striking similarity to the AD scale. A fourth symptom cluster was described by perception and expression of emotions. The factor analyses strongly support the construct validity of the diagnostic rating scales.

- The aim of this study was to describe the occurrence of vitality affects and basic affects and to shed light on their importance in terms of patients' inner change through art therapy. In an earlier study, where 17 women were interviewed about inner change through art therapy, a secondary deductive content analysis of images and statements was performed exploring the presence of vitality affects and basic affects. Nine of the 17 interviews contained clear descriptions of vitality affects and basic affects in the intersubjective communication between the patient and the therapist, these affects were also mirrored in the patients’ painted images.Three cases are used to illustrate the result and how affects were related to inner change. These three cases differ from each other in that they described vitality affects either arising from the art therapist’s empathetic verbal or non-verbal response, from a particular experience in nature, or from the interpreted symbolic language of the image. The common denominator uniting the three cases was the intersubjective communication with the therapist. This study indicates that image making in art therapy gives rise to vitality affects and basic affects that contributes to inner change. It also indicates the importance of having trust in both the method and the art therapist.

- This study aimed to identify preclinical Alzheimer's disease (AD) in patients with mild cognitive impairment (MCI) using measurements of both regional cerebral blood flow (rCBF) and cerebrospinal fluid (CSF) biomarkers. Baseline rCBF assessments ((133)Xe method) were performed in 70 patients with MCI who were cognitively stable for 4-6 years, 69 patients with MCI who subsequently developed AD, and 33 healthy individuals. CSF was collected at baseline and analyzed for beta-amyloid(1-42), total tau and phophorylated tau. In contrast to patients with stable MCI, those who subsequently developed AD had decreased rCBF in the temporo-parietal cortex already at baseline. The relative risk of future progression to AD was particularly increased in MCI patients with decreased rCBF in parietal cortex (hazard ratio 3.1, P<0.0001). Subjects with pathological levels of both CSF tau and beta-amyloid(1-42) were also at high risk of developing AD (hazard ratio 13.4, P<0.0001). The MCI patients with a combination of decreased parietal rCBF and pathological CSF biomarkers at baseline had a substantially increased risk of future development of AD, with a hazard ratio of 24.3 (P<0.0001), when compared to those with normal CSF biomarkers. Moreover, decreased parietal rCBF (but not CSF biomarkers) was associated with a more rapid progression to AD. In conclusion, the combination of rCBF and CSF biomarkers improves the risk assessment of progression to AD in patients with MCI.

- Aim: This study investigated the relationship between sexual debut before 14 years of age and socio-demographics, sexual experience, health, experience of child abuse and behaviour at 18 years of age. Methods: A sample of 3432 Swedish high school seniors completed a survey about sexuality, health and abuse at the age of 18. Results: Early debut was positively correlated with risky behaviours, such as the number of partners, experience of oral and anal sex, health behaviours, such as smoking, drug and alcohol use, and antisocial behaviour, such as being violent, lying, stealing and running away from home. Girls with an early sexual debut had significantly more experience of sexual abuse. Boys with an early sexual debut were more likely to have a weak sense of coherence, low self-esteem and poor mental health, together with experience of sexual abuse, selling sex and physical abuse. A multiple logistic regression model showed that a number of antisocial acts and health behaviours remained significant, but early sexual debut did not increase the risk of psychiatric symptoms, low self-esteem or low sense of coherence at 18 years of age. Conclusion: Early sexual debut was associated with problematic behaviours during later adolescence, and this vulnerability requires attention from parents and healthcare providers.

- <i>Background/Aim: </i>The aim was to identify subjects with incipient Alzheimer’s disease (AD) among patients with mild cognitive impairment (MCI) using brief cognitive tests. <i>Methods: </i>A total of 147 MCI patients were followed for 4–6 years and the incidence of AD was 11.6%/year. At baseline, the cube copying test, clock drawing test, MMSE and measurements of regional cerebral blood flow (rCBF) and cerebrospinal fluid (CSF) β-amyloid<sub>1–42</sub> (Aβ<sub>42</sub>) were performed. <i>Results: </i>The cube copying test, but not the clock drawing test, could predict AD among MCI patients with an area under the receiver operating characteristic curve of 0.64 (p < 0.01). The relative risk for future AD was increased in MCI subjects with impaired cube copying test (sex- and age-adjusted hazard ratio = 1.8, p < 0.05) and the incidence of AD was 18.2% in this subgroup. Combining the cube copying test with either rCBF or CSF Aβ<sub>42</sub> had additive effects on the risk assessment for future development of AD. MCI patients achieving high scores on both MMSE and cube copying test had a very low risk of developing AD (incidence of AD = 1.6%). <i>Conclusion: </i>In conclusion, combinations of the cube copying test with MMSE, rCBF and CSF Aβ<sub>42</sub> measurements can identify subgroups of MCI subjects with either substantially reduced or increased risk for future development of AD.

- BackgroundPartners of patients with heart failure provide both practical and emotional support. Many partners assume caregiving responsibilities without being aware of the burden related with this role.ObjectiveOur work has established that a psycho-educational intervention has benefits at 3, but not at 12 months for patients with heart failure. Further we had not described the long-term effects in caregivers. This study aimed to determine the 24-months effects of a dyadic psycho-educational intervention on caregiver burden and morbidity in partners of patients with heart failure and study factors associated with a change in caregiver burden.DesignA randomized controlled study design, with a follow-up assessment after 24 months.Setting and participantsPartners to patients with heart failure were recruited from two hospitals in the southeast of Sweden.InterventionA three session nurse-led psycho-educational program was tested and included psychosocial support to maintain the partners’ physical and mental functions, and perceived control. Several instrument were used to measure caregiver burden, perceived control, physical and mental health, depression and morbidity.ResultsOne hundred fifty-five partners were included. There were no significant differences in any index of caregiver burden or morbidity among the partners in the intervention and control groups after 24 months. Overall, the mean total caregiver burden was found to be significantly increased compared to baseline (36 ± 12 vs 38 ± 14, p < 0.05). A younger partner, less comorbidity, higher levels of perceived control, better physical health and less symptoms of depression in patients, and better mental health in the partners were factors associated with absence of increased caregiver burden over time.Discussion and conclusionOur intervention did not significantly decrease caregiver burden or morbidity. Over time, several aspects of burden increased in both groups. To improve outcomes, individualized and targeted interventions might be beneficial.

Trends in treatment with antipsychotic medication in relation to national directives, in people with dementia : a review of the Swedish context
- 2017
-
Ingår i: BMC Psychiatry. - London : BioMed Central. - 1471-244X. ; 17, s. 1-9

Forskningsöversikt (refereegranskat)abstract
- Background: The aim of this study was to explore trends in treatment with antipsychotic medication in Swedish dementia care in nursing homes as reported in the most recent empirical studies on the topic, and to relate these trends to directives from the national authorities. Methods: The study included two scoping review studies based on searches of electronic databases as well as the Swedish directives in the field. Results: During the past decade, directives have been developed for antipsychotic medication in Sweden. These directives were generic at first, but have become increasingly specific and restrictive with time. The scoping review showed that treatment with antipsychotic drugs varied between 6% and 38%, and was higher in younger older persons and in those with moderate cognitive impairment and living in nursing homes for people with dementia. A decreasing trend in antipsychotic use has been seen over the last 15 years. Conclusions: Directives from the authorities in Sweden may have had an impact on treatment with antipsychotic medication for people with dementia. Treatment with antipsychotic medication has decreased, while treatment with combinations of psychotropic medications is common. National directives may possibly be even more effective, if applied in combination with systematic follow-ups.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION Families may benefit from increased focus on partner emotional well-being during pregnancy and the perinatal period. Our aim was to explore the risk for depression and anxiety during pregnancy and one year postpartum in relation to partners' self-reported health, sense of coherence, social support, and lifestyle factors. METHODS This is a longitudinal cohort study using three questionnaires that were answered twice during pregnancy and at one year postpartum. Participants (n=532) were recruited between April 2012 and September 2013, and follow-up was between April 2012 and March 2015, in Sweden.RESULTS In late pregnancy, 8.9% of the prospective partners were at high risk for depression and 8.3% one year postpartum. An increased risk for depression was found amongst those reporting 'fair or very poor' sexual satisfaction and those reporting 'fair or very poor' health during pregnancy and postpartum. High anxiety was reported by 10.8% during late pregnancy and 12.4% one year postpartum. Partners who were unemployed, had financial difficulties, and who scored low on a Sense of Coherence scale, showed significantly higher anxiety in late pregnancy and postpartum. Social support has a significant and positive impact concerning signs of depression and anxiety, both during pregnancy and postpartum. CONCLUSIONS More than 10% of partners in this study showed depressive symptoms and anxiety, indicating a problem in need of attention by stakeholders. Strengthening social support is of greatest importance. It is time for the introduction of family-focused care aimed at prevention of depression and anxiety, and maintenance of family well- being.

- Major depression occurs in 5-10% of pregnancies and is associated with many negative effects for mother and child, yet treatment options are scarce. To our knowledge, this is the first published randomised controlled trial on Internet delivered Cognitive Behavior Therapy (ICBT) for this group.Objective: To test the efficacy of a pregnancy adapted version of an existing 10-week ICBT-program for depression as well as assessing acceptability and adherence.Design: Randomised controlled trial.Setting: Online and telephone.Population or sample: Self-referred pregnant women (gestational week 10-28 at intake) currently suffering from major depressive disorder.Methods: 42 pregnant women (gestational week 12-28) with major depression were randomised to either treatment as usual (TAU) provided at their antenatal clinic or to ICBT as an add-on to usual care.Main outcome measures: The primary outcome was depressive symptoms measured with the Montgomery-Asberg depression rating scale-self report (MADRS-S). The Edinburgh Postnatal Depression Scale and measures of anxiety and sleep were used. Credibility, satisfaction, adherence and utilization were also assessed.Results: The ICBT group had significantly lower levels of depressive symptoms post treatment (p < 0.001, Hedges g = 1.21) and were more likely to be responders (i.e. achieve a statistically reliable improvement) (RR = 0.36; p = 0.004). Measures of treatment credibility, satisfaction, utilization, and adherence were comparable to implemented ICBT for depression.Limitations: Small sample size and no long-term evaluation.Conclusion: Pregnancy adapted ICBT for antenatal depression is feasible, acceptable and efficacious. These results need to be replicated in larger trials to validate these promising findings.
