BackgroundLittle is known about time perception, its putative role as cognitive endophenotype, and its neuroanatomical underpinnings in adults with attention deficit hyperactivity disorder (ADHD).MethodTwenty adults with ADHD, 20 unaffected first-degree relatives and 20 typically developing controls matched for age and gender undertook structural magnetic resonance imaging scans. Voxel-based morphometry with DARTEL was performed to obtain regional grey-matter volumes. Temporal processing was investigated as a putative cognitive endophenotype using a temporal reproduction paradigm. General linear modelling was employed to examine the relationship between temporal reproduction performances and grey-matter volumes.ResultsADHD participants were impaired in temporal reproduction and unaffected first-degree relatives performed in between their ADHD probands and typically developing controls. Increased grey-matter volume in the cerebellum was associated with poorer temporal reproduction performance.ConclusionsAdults with ADHD are impaired in time reproduction. Performances of the unaffected first-degree relatives are in between ADHD relatives and controls, suggesting that time reproduction might be a cognitive endophenotype for adult ADHD. The cerebellum is involved in time reproduction and might play a role in driving time performances.

The purpose of this study was to determine whether adolescents with and without attention-deficit/hyperactivity disorder (ADHD) differ regarding their friendships. The sample comprised 107 adolescents (59 ADHD, 48 typically developing comparison), ages 13 to 18 years. Adolescents and their parents completed questionnaires that measured the number and duration of the adolescents’ friendships, the frequency of contact they had with their friends, and the characteristics of their friends. Adolescents with and without ADHD did not differ in the number of friends they nominated, the duration of their friendships, and the frequency of contact with friends. Adolescents with ADHD were more likely to have friends who were younger or older by two or more years and close friends with behavior problems than comparison adolescents. Girls with ADHD had fewer of their friendships corroborated by parents than girls without ADHD, and fewer of their best friends attending their school. Only girls with ADHD had friends whom they initially met online.
