Journal ArticleDOI
The heritability of clinically diagnosed attention deficit hyperactivity disorder across the lifespan
TL;DR: The finding of high heritability for clinically diagnosed ADHD in adults indicates that the previous reports of low heritability are best explained by rater effects, and that gene-identification studies of ADHD in adult need to consider pervasiveness and developmentally informative data.
Journal ArticleDOI
Autism Spectrum Disorders and Autisticlike Traits Similar Etiology in the Extreme End and the Normal Variation
Sebastian Lundström,Zheng Chang,Maria Råstam,Christopher Gillberg,Henrik Larsson,Henrik Anckarsäter,Paul Lichtenstein +6 more
TL;DR: An etiological similarity between ASDs and ALTs in the normal variation is demonstrated and, with results from previous studies, the data suggest that ASDsand ALTs are etiologically linked.
Journal ArticleDOI
Serious transport accidents in adults with attention-deficit/hyperactivity disorder and the effect of medication: a population-based study.
TL;DR: Attention-deficit/hyperactivity disorder is associated with an increased risk of serious transport accidents, and this risk seems to be possibly reduced by ADHD medication, at least among male patients.
Journal ArticleDOI
Childhood attention-deficit hyperactivity disorder as an extreme of a continuous trait: a quantitative genetic study of 8,500 twin pairs.
TL;DR: The data suggest that ADHD is best viewed as the quantitative extreme of genetic and environmental factors operating dimensionally throughout the distribution of ADHD symptoms, indicating that the same etiologic factors are involved in the full range of symptoms of inattention, hyperactivity and impulsivity.
Journal ArticleDOI
Depression and violence: a Swedish population study.
TL;DR: Depressive symptoms were associated with increased risk of violent crime and a sensitivity analysis identified little difference in risk estimate when all crimes (violent and non-violent) was the outcome.
