BACKGROUND To date, nearly all research of subtype differences in ADHD has been performed in children and only two studies, with conflicting results, have covered this subject in adults with ADHD. OBJECTIVE This study examined subtype differences in the clinical presentation of ADHD-symptoms, related psychopathological features, psychosocial functioning(More)
The anterior cingulate cortex (ACC) is crucially involved in executive control of attention. Here, seven medication-naïve adult patients suffering from attention deficit/hyperactivity disorder (ADHD) were studied with 2D (1)H-magnetic resonance spectroscopic imaging (MRSI) of the ACC [Brodmann areas 24b'-c' and 32'] twice, once before initiation of(More)
BACKGROUND The German version of the Conners Adult ADHD Rating Scales (CAARS) has proven to show very high model fit in confirmative factor analyses with the established factors inattention/memory problems, hyperactivity/restlessness, impulsivity/emotional lability, and problems with self-concept in both large healthy control and ADHD patient samples. This(More)
The anterior cingulate cortex (ACC) plays a major role in modulating executive control of attention. Here, 15 medication-nai ve patients with attention deficit/hyperactivity disorder (ADHD) and 10 carefully matched healthy controls were studied with 2D (1)H-magnetic resonance spectroscopic imaging (MRSI) of the ACC [Brodmann areas 24b'-c' and 32'].(More)
OBJECTIVE This exploratory study aims to compare lifetime psychiatric axis-I-comorbidity and psychosocial functioning in a clinically referred sample of adult patients with attention-deficit/hyperactivity disorder (ADHD) with a population-based healthy control group and to examine whether patients with ADHD and lifetime comorbid diagnoses differ from(More)
OBJECTIVES This trial was performed to test the efficacy and safety of an extended-release formulation of methylphenidate (MPH ER). METHODS A total of 162 adults with ADHD according to DSM-IV were treated for 8 weeks with either two daily individually body weight-adjusted doses of MPH ER up to 1 mg/kg per day (N = 84) or placebo (N = 78). The primary(More)
OBJECTIVES Treatment investigations with methylphenidate in adults with ADHD focus preferentially on the classical psychopathology: inattention, hyperactivity and impulsivity. ADHD-associated emotional symptoms, which are frequently present at least in ADHD subpopulations, were studied rarely. The vast majority of the placebo-controlled trials had(More)
Sleep disorders are common in adults with attention deficit/hyperactivity disorder (ADHD). Two sleep questionnaires; the Brown ADD Scale, the Symptom-Checklist-90-R, and a self-developed symptom questionnaire were administered in this study. In a sample of 61 patients without comorbidity, current substance abuse and medication intake, sleep problems were(More)
The present study was intended to examine the efficacy of immediate-release methylphenidate (MPH IR) in the treatment of adults with attention-deficit hyperactivity disorder (ADHD) under consideration of subtype according to DSM-IV criteria and psychiatric comorbidity. After baseline assessment over 3 weeks, 47 patients aged 18-59 years with combined ADHD(More)
