Electrophysiological data were examined in control adults and adults with ADHD during a cued visual spatial selective attention task where in addition to directing attention, the cue probabilistically predicted the presence of a distractor. Late activity following the cue (ADAN) showed attention modulation for all participants. However, only ADHD participants showed additional significant distractor anticipation modulations. Stimulus related activity showed modulations of early visual processing (P1) as a function of attention and anticipated distractor presence for all participants suggesting functional facilitation and suppression. Findings suggest functional visual spatial selective attention in adults with ADHD.展开更多

It is not known if psychostimulants decrease symptoms of both ADHD and alexithymia. This relationship is examined in a small naturalistic and longitudinal study. Participants: Ten consecutive stimulant-naive college students seek assessment and treatment for ADHD during the academic year. Method: Participants completed three self-report instruments quantifying ADHD symptomatology, alexithymia, and psychological mindedness prior to initiation of stimulant pharmacotherapy and after three and six months of medication treatment without formal psychotherapy. Results: ADHD symptoms decreased significantly from baseline to three months and remained low at six months. Decreases in alexithymia and increases in psychological mindedness changed more slowly, with significant differences occurring at six months compared to baseline. Conclusions: This study suggests that stimulant pharmacotherapy in college students with ADHD decreases ADHD symptoms and alexithymia while increasing psychological mindedness. These results have implications for untreated adult ADHD patients seeking psychotherapy.展开更多

Furthermore, we examined to what extent adults with PDD think that they exhibit ADHD symptoms. Methods: We developed an original Japanese self-report questionnaire to determine the presence or absence of 18 symptoms from the diagnostic criteria for ADHD in the DSM-IV-TR. We administered the questionnaire to 64 adults with high-functioning PDD (45 men and 19 women) and 21 adults with ADHD (10 men and 11 women), aged 18 to 59 years, with a full-scale intelligence quotient ≥75. Target patients were evaluated for ADHD by their psychiatrists. Results: Twenty-nine (45.3%) adults with PDD also had ADHD. The percentage of these adults who had over six perceived inattention symptoms from the DSM-IV-TR was 96.6%. The percentage of these adults who had over six perceived hyperactivity-impulsivity symptoms was 65.5%. Thirty-five (55.6%) adults with PDD responded that they were aware of having ADHD symptoms at the level of the relevant diagnostic criteria. Conclusions: The present study is the first to examine the frequency of objective and perceived ADHD symptoms in adults with PDD in Japan. Our results show that both objective and perceived ADHD symptoms frequently appear in a large number of adults with PDD. This suggests that it is necessary to attend to concomitant ADHD symptoms in the medical care of adults with PDD.展开更多
