OBJECTIVE The authors examined parent-of-origin effects in transmission of ADHD and neuropsychological functioning. Proof of these effects can identify more etiologically homogeneous ADHD subgroups and facilitate genetic studies. METHOD The authors included 238 ADHD and 147 control families. ADHD in children was assessed using parent and teacher ratings, while parents completed self-reports. ...

OBJECTIVE To examine the specificity of deficits in focused attention and sustained attention in adults with ADHD and to evaluate the effect of comorbidity. METHOD Twenty-eight adults with ADHD without comorbidity were compared with 28 ADHD outpatients with comorbidity. Two control groups were used: 68 adults referred for ADHD but with another psychopathology rather than ADHD (non-ADHD) and 2...

OBJECTIVE This study examined the extent to which ADHD was associated with risky sexual behaviors (RSBs) in a sample of 92 undergraduates with (n = 44) and without (n = 48) ADHD. Mother-child relationship quality was examined as a potential moderator. METHOD We conducted comprehensive assessments for ADHD and comorbid conditions and collected measures of RSB and mother-child relationship qual...

Background and Objectives: Most of the previous studies investigated prevalence of attention-deficit/hyperactivity disorder (ADHD) among university students with self report measures. Present study investigated actual prevalence of ADHD and comorbid disorders among university students in Cumhuriyet University of Sivas in Turkey. Methods: In the first stage, 980 university students filled in the...

Attention-deficit/hyperactivity disorder (ADHD) was originally defined in children but is now recognized to persist into adulthood for some patients. Despite this recognition, adult ADHD remains underdiagnosed. This narrative review describes the negative impact of ADHD across multiple functional domains, diagnostic guidelines for adult ADHD and its clinical features, the importance of screenin...

OBJECTIVES To estimate the excess costs for children in the years surrounding initial diagnosis of attention-deficit/hyperactivity disorder (ADHD) and to estimate differences in treatment costs by ethnicity. DESIGN We identified children diagnosed with ADHD and estimated their health service costs in the 2 years before and 2 years after initial diagnosis of ADHD. Costs were compared with thos...

Parents of children with attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) often have elevated ADHD and depressive symptoms, both of which increase the risk of ineffective parenting and interparental discord. However, little is known about whether child ADHD/ODD behavior and parent ADHD or depressive symptoms uniquely or synergistically predict the quality ...

Individuals with ADHD may self-medicate with nicotine, the main psychoactive ingredient in tobacco smoke, in order to reduce symptoms and negative moods associated with ADHD. ADHD medication (e.g., methylphenidate and atomoxetine) may mimic some of the effects of nicotine and may aid smoking cessation in smokers with ADHD. The present study examined if ADHD medication reduces smoking and withdr...

Attention Deficit Hyperactivity Disorder (ADHD) is characterized clinically by hyperactive/impulsive and/or inattentive symptoms which determine diagnostic subtypes as Predominantly Hyperactive-Impulsive (ADHD-HI), Predominantly Inattentive (ADHD-I), and Combined (ADHD-C). Neuroanatomically though we do not yet know if these clinical subtypes reflect distinct aberrations in underlying brain org...
