- Importance: Individuals released from prison have high rates of violent reoffending, and there is uncertainty about whether pharmacological treatments reduce reoffending risk.Objective: To investigate the associations between major classes of psychotropic medications and violent reoffending.Design, Setting, and Participants: This cohort study included all released prisoners in Sweden from July 1, 2005, to December 31, 2010, through linkage of population-based registers. Rates of violent reoffending during medicated periods were compared with rates during nonmedicated periods using within-individual analyses. Follow-up ended December 31, 2013.Exposures: Periods with or without dispensed prescription of psychotropic medications (antipsychotics, antidepressants, psychostimulants, drugs used in addictive disorders, and antiepileptic drugs) after prison release. Prison-based psychological treatments were investigated as a secondary exposure.Main Outcomes and Measures: Violent crime after release from prison.Results: The cohort included 22 275 released prisoners (mean [SD] age, 38 [13] years; 91.9% male). During follow-up (median, 4.6 years; interquartile range, 3.0-6.4 years), 4031 individuals (18.1%) had 5653 violent reoffenses. The within-individual hazard ratio (HR) associated with dispensed antipsychotics was 0.58 (95% CI, 0.39-0.88), based on 100 events in 1596 person-years during medicated periods and 1044 events in 11 026 person-years during nonmedicated periods, equating to a risk difference of 39.7 (95% CI, 11.3-57.7) fewer violent reoffenses per 1000 person-years. The within-individual HR associated with dispensed psychostimulants was 0.62 (95% CI, 0.40-0.98), based on 94 events in 1648 person-years during medicated periods and 513 events in 4553 person-years during nonmedicated periods, equating to a risk difference of 42.8 (95% CI, 2.2-67.6) fewer violent reoffenses per 1000 person-years. The within-individual HR associated with dispensed drugs for addictive disorders was 0.48 (95% CI, 0.23-0.97), based on 46 events in 1168 person-years during medicated periods and 1103 events in 15 725 person-years during nonmedicated periods, equating to a risk difference of 36.4 (95% CI, 2.1-54.0) fewer violent reoffenses per 1000 person-years. In contrast, antidepressants and antiepileptics were not significantly associated with violent reoffending rates (HR = 1.09 [95% CI, 0.83-1.43] and 1.14 [95% CI, 0.79-1.65], respectively). The most common prison-based program was psychological treatments for substance abuse, associated with an HR of 0.75 (95% CI, 0.63-0.89), which equated to a risk difference of 23.2 (95% CI, 10.3-34.1) fewer violent reoffenses per 1000 person-years.Conclusions and Relevance: Among released prisoners in Sweden, rates of violent reoffending were lower during periods when individiduals were dispensed antipsychotics, psychostimulants, and drugs for addictive disorders, compared with periods in which they were not dispensed these medications. Further research is needed to understand the causal nature of this association.

- Objective: (1) investigate the associations of attention-deficit/hyperactivity disorder (ADHD) with systolic and diastolic blood pressure, resting heart rate, pulse pressure (PP), physical fitness, and BMI; (2) explore whether cardiovascular risk factors and ADHD share genetic and environmental influences; (3) assess if pharmacological treatment for ADHD influences these associations.Methods: We identified 395,978 individuals born between 1973 and 1991 who had military conscription examinations at a mean age of 18.3 years (SD = 0.57) and their full-siblings within the same cohort (N = 208,060) by linking population-based registers in Sweden. Results Significantly increased risk of ADHD was observed in individuals with low systolic blood pressure (SBP) and PP, low physical fitness, and in those who had overweight or obesity after adjustments (adjusted Odds Ratio [OR] ranging from 1.10 to 1.45). Full siblings of individuals with low SBP, low physical fitness, and obesity were more likely to receive an ADHD diagnosis compared to full siblings without those risk factors (OR ranging from 1.17 to 1.31). Additionally, analyses showed robust associations between ADHD and low SBP, low physical fitness, and obesity, even in ADHD medication-naïve individuals.Conclusions: Individuals with several cardiovascular risk factors are more often diagnosed with ADHD, regardless of psychiatric comorbidity. These association are not explained by ADHD pharmacotherapy, rather, they are in part due to shared familial risk factors.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Medications that are used for treatment of metabolic disorders have been suggested to be associated with the development of amyotrophic lateral sclerosis (ALS).METHODS: To examine the associations of antidiabetics and statins with the subsequent risk of ALS we conducted a population-based nested case-control study of 2,475 Swedish residents diagnosed with ALS during July 2006-December 2013, and 12,375 population controls (five for each ALS case). We extracted from the Swedish Prescribed Drug Register information on filled prescriptions of antidiabetics and statins for both cases and controls during the years before ALS diagnosis. Conditional logistic regression was used to calculate odds ratios (ORs) for the associations of these medications with ALS risk.RESULTS: ALS patients were less likely to have been prescribed with antidiabetics, compared to controls (OR=0.76, 95%CI=0.65-0.90). Conversely, statins were not associated with ALS risk overall (OR=1.08, 95%CI=0.98-1.19), although a positive association was noted among women (OR=1.28, 95%CI=1.10-1.48). The latter association was mostly explained by ALS cases being more likely to have a first prescription of statins during the year before diagnosis, compared to controls (OR=2.54, 95%CI=1.84-3.49).CONCLUSIONS: The inverse association of antidiabetics with ALS is consistent with the previously reported inverse association between type 2 diabetes and ALS risk. The increase in prescription of statins during the year before ALS diagnosis deserves attention because it might reflect an acceleration of the course of ALS due to statin use.

How is ADHD associated with comorbidities and health related outcomes? : The role of familial factors and ADHD during pregnancy
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder characterized by impaired attention and hyperactivity/impulsivity. ADHD is associated with several comorbidities and health-related outcomes. However, it is uncertain whether ADHD is more strongly associated with certain disorder domains, and whether ADHD-related comorbidities and health-related outcomes is important to consider during pregnancy. Aims: To expand the knowledge regarding the genetic overlap between ADHD and other psychiatric disorder symptoms, and to increase the awareness and understanding related to ADHD in women, with a focus on adverse health behaviors, mental health problems, and pregnancy outcomes. Methods: The present thesis includes one systematic review and metaanalysis (Study I), and three studies based on population-based register data from Sweden (Study II, III, and IV), and Norway (Study II).Results: Individuals with ADHD have an increased liability to meet criteria for externalizing, internalizing and neurodevelopmental disordersymptoms, and these co-occurrences are partly due to shared genetic risks. Further, ADHD is an important risk factor to consider before, during and after pregnancy, as ADHD increases the risk of smoking during pregnancy, mental health problems postpartum, and adverse pregnancy outcomes.Conclusions: The genetic overlaps between ADHD and other psychiatric disorder symptoms were similar across disorder dimensions. Further, results demonstrated that ADHD is an important risk factor to consider in women surrounding pregnancy. These findings point towards the importance of recognizing that women diagnosed with ADHD need to be prioritized and allowed more attention and support by the healthcare system, specifically during their fertile years.

- Objective: To investigate the association between drug treatment for attention-deficit/hyperactivity disorder (ADHD) and risk of concomitant suicidal behaviour among patients with ADHD.Design: Register based longitudinal study using within patient design.Setting: Linkage of multiple national registers in Sweden.Participants: 37,936 patients with ADHD born between 1960 and 1996 and followed from 2006 to 2009 for treatment status by ADHD drug treatment and suicide related events (suicide attempt and completed suicide).Main outcome measure: Incidence rate of suicide related events during ADHD drug treatment periods compared with that during non-treatment periods.Results: Among 37,936 patients with ADHD, 7019 suicide related events occurred during 150,721 person years of follow-up. At the population level, drug treatment of ADHD was associated with an increased rate of suicide related events (hazard ratio 1.31, 95% confidence interval 1.19 to 1.44). However, the within patient comparison showed a reverse association between ADHD drug treatment and rate of suicide related events (0.89, 0.79 to 1.00). Among stimulant users, a reduced within patient rate of suicide related events was seen during treatment periods (0.81, 0.70 to 0.94). Among non-stimulant/mixed users, no significantly increased within patient rate of suicide related events during non-stimulant treatment periods was seen (0.96, 0.72 to 1.30).Conclusions: This study found no evidence for a positive association between the use of drug treatments for ADHD and the risk of concomitant suicidal behaviour among patients with ADHD. If anything, the results pointed to a potential protective effect of drugs for ADHD on suicidal behaviour, particularly for stimulant drugs. The study highlights the importance of using within patient designs to control for confounding in future pharmacoepidemiological studies.

Attention-Deficit/Hyperactivity Disorder (ADHD) Beyond the Young Age : Investigation of the Prevalence of ADHD in Older Adults and the Risk of Age-related Disorders
- 2023
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by impairing levels of inattention and/or hyperactivity-impulsivity. Symptoms of ADHD, which typically emerge in childhood, may persist until older age with a substantial adverse impact on health and functionality. Yet there is a notable knowledge gap in research on ADHD in older age and the potential associations of adult ADHD with disorders that are common in older age (i.e., age-related disorders). Thus, this thesis aimed to investigate the prevalence rates of ADHD in older age and whether ADHD in adulthood is associated with an increased risk of age-related disorders. Study I, a systematic review and meta-analysis, suggests that a considerable number of older adults report elevated levels of ADHD symptoms, while the prevalence of treated ADHD is less than half of the prevalence of clinically diagnosed ADHD. In Studies II, III, and IV, we used data from Swedish population registers. We found that ADHD is associated with an increased risk of dementia and mild cognitive impairment (Study II), which substantially attenuates after controlling for psychiatric comorbidity. Further, ADHD symptoms in adulthood are associated with an increased risk of subsequent cardiometabolic disorders (Study III). The associations attenuate after controlling for educational attainment, psychiatric comorbidity, and lifestyle factors, and they are confounded by genetic factors. Finally, the prediction of cardiovascular risk in adults initiating pharmacological treatment for ADHD may improve by considering novel risk factors (i.e., psychiatric comorbidity and use of other psychotropic medications) in addition to traditional predictors (Study IV). Overall, the findings indicate that a substantial number of older adults have increased levels of ADHD symptoms and that ADHD in adults is associated with an increased risk of age-related disorders. Further longitudinal studies, based on both community samples and epidemiological data, are needed to explore the risk of age-related disorders in ADHD, and the underlying mechanisms, until a more advanced older age.

Antipsychotics, mood stabilisers, and risk of violent crime
- 2014

Ingår i: The Lancet. - London, United Kingdom : The Lancet Publishing Group. - 0140-6736 .- 1474-547X. ; 384:9949, s. 1206-1214

Tidskriftsartikel (refereegranskat)abstract
- Background: Antipsychotics and mood stabilisers are prescribed widely to patients with psychiatric disorders worldwide. Despite clear evidence for their efficacy in relapse prevention and symptom relief, their effect on some adverse outcomes, including the perpetration of violent crime, is unclear. We aimed to establish the effect of antipsychotics and mood stabilisers on the rate of violent crime committed by patients with psychiatric disorders in Sweden.Methods: We used linked Swedish national registers to study 82,647 patients who were prescribed antipsychotics or mood stabilisers, their psychiatric diagnoses, and subsequent criminal convictions in 2006-09. We did within-individual analyses to compare the rate of violent criminality during the time that patients were prescribed these medications versus the rate for the same patients while they were not receiving the drugs to adjust for all confounders that remained constant within each participant during follow-up. The primary outcome was the occurrence of violent crime, according to Sweden's national crime register.Findings: In 2006-09, 40,937 men in Sweden were prescribed antipsychotics or mood stabilisers, of whom 2657 (6·5%) were convicted of a violent crime during the study period. In the same period, 41,710 women were prescribed these drugs, of whom 604 (1·4 %) had convictions for violent crime. Compared with periods when participants were not on medication, violent crime fell by 45% in patients receiving antipsychotics (hazard ratio [HR] 0·55, 95% CI 0·47-0·64) and by 24% in patients prescribed mood stabilisers (0·76, 0·62-0·93). However, we identified potentially important differences by diagnosis-mood stabilisers were associated with a reduced rate of violent crime only in patients with bipolar disorder. The rate of violence reduction for antipsychotics remained between 22% and 29% in sensitivity analyses that used different outcomes (any crime, drug-related crime, less severe crime, and violent arrest), and was stronger in patients who were prescribed higher drug doses than in those prescribed low doses. Notable reductions in violent crime were also recorded for depot medication (HR adjusted for concomitant oral medications 0·60, 95% CI 0·39-0·92).Interpretation: In addition to relapse prevention and psychiatric symptom relief, the benefits of antipsychotics and mood stabilisers might also include reductions in the rates of violent crime. The potential effects of these drugs on violence and crime should be taken into account when treatment options for patients with psychiatric disorders are being considered.Funding: The Wellcome Trust, the Swedish Prison and Probation Service, the Swedish Research Council, and the Swedish Research Council for Health, Working Life and Welfare.
