Objective: The main aim of this study was to examine the efficacy, tolerability, and compliance of an extended-release formulation of methylphenidate (OROS-MPH) in adults with ADHD receiving immediate-release methylphenidate (IR-MPH). Method: Participants were outpatient adults with ADHD who were stable on IR-MPH-administered TID. Participants…

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder, with concomitant executive function deficits often being the focus of empirical and clinical investigation. This study explored the validity of the Behavior Rating Inventory of Executive Function Parent Form (BRIEF; Gioia, Isquith, Guy, & Kenworthy, 2000) for…

Sensory processing difficulties (SPD) are prevalent among children with ADHD. Yet, the question whether different SPD characterize children with different types of ADHD has not received enough attention in the literature. The current study characterized sensory processing difficulties (SPD) of children with different types of ADHD and explored the…

Individuals with ADHD often show performance deficits in motor tasks. It is not clear, however, whether this reflects less effective acquisition of skill (procedural knowledge), or deficient consolidation into long-term memory, in ADHD. The aim of the study was to compare the acquisition of skilled motor performance, the expression of…

Objective: The main objective of this article is to investigate the type of personality disorders and clinical syndromes (CSs) that were best related to ADHD symptoms among prisoners. Method: The authors screened for childhood and adult ADHD symptoms and administered the Millon Clinical Multiaxial Inventory-III (MCMI-III) to 196 serving prisoners.…

Objective: Iron deficiency is associated with impaired dopaminergic signaling and externalizing behavior. The authors examine, whether iron stores in toddlerhood influence later response to psychostimulants. Method: Youth participating in a study monitoring the long-term safety of risperidone were included in this analysis if they had received…

Objective: This study examined the relationship of ADHD symptoms to different aspects of close friendship quality as rated by both adolescents (target adolescent and a close friend) within a friendship dyad. Method: Participants were 41 same-sex friendship dyads who completed questionnaires about their friendship. Separate symptom dimensions of…

Objective: This study examines the relative relationships of self- and other-reports of adult ADHD symptoms to important life competencies, and also investigates whether self- and other-reports of ADHD symptoms are differentially associated with interrater differences in reports of competence. Method: A total of 91 women completed a…

Objective: There are presently almost no empirically validated treatments for adolescents with ADHD. However, in childhood, behavioral treatments for ADHD typically include behavioral parent training, classroom interventions, and intensive child-directed interventions. Method: The present investigation examines treatment gains following an 8-week…

Objective: This study examined social information processing (SIP) of events with varied outcomes in children with ADHD and conduct problems (CPs; defined as oppositional defiant disorder [ODD] or conduct disorder [CD]) and controls. Method: Participants were 64 children (46 boys, 18 girls) aged 6 to 12, including 39 with ADHD and 25 controls.…

Background: Twin studies using both clinical and population-based samples suggest that the frequent co-occurrence of attention deficit hyperactivity disorder (ADHD) and reading ability/disability (RD) is largely driven by shared genetic influences. While both disorders are associated with lower IQ, recent twin data suggest that the shared genetic…

Background: Fluctuations in attention-deficit hyperactivity disorder (ADHD) symptoms related to regulatory deficits in arousal states are themselves characterized by circadian rhythms. Although cortisol is an important circadian arousal-related marker, studies focusing on across-the-day cortisol variations in ADHD are scarce. There is no study…

Objective: Attention-deficit/hyperactivity disorder (ADHD) has been linked to deficits in the dopaminergic reward-processing circuitry; yet, existing evidence is limited, and the influence of genetic variation affecting dopamine signaling remains unknown. We investigated striatal responsivity to rewards in ADHD combined type (ADHD-CT) using…

Elevated psychological distress and concomitant dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has been implicated as one pathway that links the stress of caregiving with adverse health outcomes. This study assessed whether perceived social support might mitigate the psychological, endocrine and health consequences of caregiver…

Very few studies have prospective information, especially regarding males, on the prediction of Borderline Personality Disorder (BPD) in adulthood from psychiatric disorders in childhood. Certain childhood disorders, however, have notably similar features in common with BPD. In particular, the affective dysfunction, hostility and interpersonal…
