Background. ADHD is characterized by inattention, impulsiveness and hyperactivity, but the clinical picture of ADHD seems to be broader than these behaviors. A high rate of overlap between ADHD and psychiatric disorders, other developmental disorders (developmental dyslexia, dyscalculia, language impairments), oppositional defiant disorder and conduct disorder has been found in previous researc...

BACKGROUND The frequent comorbidity between attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) raises the possibility that ADHD+CD is a distinct and separate condition. METHODS We tested hypotheses about patterns of familial association between ADHD, CD, oppositional defiant disorder (ODD) and adult antisocial personality disorder (ASPD). Using family study methodology ...

This study examines the relationship between self-reported ADHD and adult mortality over a four-year period, and whether ADHD is associated with underlying cause of death (accidents versus all others). If ADHD increases mortality risk through accidents, then interventions may be designed and implemented to reduce risk and prevent premature death. We estimate descriptive statistics and multivari...

Introduction Contrary to Diagnostic and Statistical Manual of Mental Disorders (DSM-5), fifth edition, some studies indicate that ADHD-inattentive presentation (ADHD-I) is a distinct diagnostic disorder and not an ADHD presentation. Methods In this study, 12 ADHD-combined presentation (ADHD-C), 10 ADHD-I, and 13 controls were enrolled and their resting state EEG recorded. Following this, a gr...

Higher prevalence rates of anxiety and depression have been reported in parents of children with attention-deficit/hyperactivity disorder (ADHD). The interaction between the burden of ADHD in offspring, a higher prevalence rate of this highly inherited disorder in parents, and comorbidities may explain this finding. Our objective was to investigate levels of ADHD, anxious and depressive symptom...

The present study was designed to investigate the hypothesis that children with Attention Deficit Hyperactivity Disorder combined subtype (ADHD-C) have a generalized executive functioning (EF) [Barkley, R. A. (1997). Behavioural inhibition, sustained attention, and executive functions: Constructing a unifying theory of AD/HD. Psychological Bulletin, 121, 65-94; Barkley, R. A. (1997). ADHD and t...

BACKGROUND Comorbidity between Attention-Deficit/Hyperactivity Disorder (ADHD) and depression is high, also in older adults. Thus far it is not well understood why ADHD and depression are so strongly interrelated. One factor that may play a role in older adults with ADHD is an increased risk of experiencing adverse life events. METHODS Six year follow-up data were used from the Longitudinal A...

This study examined the association between childhood ADHD and juvenile delinquency by examining data from the Pittsburgh ADHD Longitudinal Study (PALS), a follow-up study of individuals diagnosed with ADHD in childhood (ages 5-12) and recontacted in adolescence and young adulthood for yearly follow-up (age at first follow-up interview M = 17.26, SD = 3.17). Participants were 288 males with chi...

OBJECTIVE To examine ADHD prevalence, rating scales, and relationship to nicotine use in adults with schizophrenia or Asperger syndrome. METHOD Ninety-five individuals, 41 with schizophrenia and 54 with Asperger syndrome, were included. Self-rating of adult ADHD symptoms with the Wender-Reimherr Adult Attention Deficit Diagnostic Rating Scale (WRAADDS), parent rating of proband's ADHD childho...

OBJECTIVE To determine frequency of motor alterations in children with attention deficit hyperactivity disorder (ADHD). METHOD We evaluated 19 children aged 7-12 years with ADHD classified in three sub-types: Combined (ADHD-C), with Inattention (ADHD-I), and with Hyperactivity (ADHD-H). Controls were age- and gender matched healthy children. We utilized Bruininks-Oseretsky Test of Motor Profi...
