The present study includes scalp electrophysiological data.

Converging evidence from these studies point at alterations in fronto-striatal networks (for an overview, see Bush, 2010) which are essential for regulation of attention and behavior, and influence inhibitory control ( Durston et al., 2002, 2003). Recent neuroimaging studies of individuals with ADHD indicate that multiple brain regions are involved in the pathophysiology of ADHD. These symptoms can lead to poorer neuropsychological performance, emotional reactivity, and motivation ( Haavik et al., 2010), and may thus interfere with academic, occupational, and social functioning ( Halleland et al., 2012). Even more commonly, adults with ADHD describe difficulties to sustain and direct attention toward relevant stimuli and, at the same time, ignoring other information that distracts them from focusing on relevant items ( Bush, 2010 Hasler et al., 2016). Symptoms in adults include increased impulsiveness and activity levels, as well as a feeling of inner restlessness. Associations between ADHD symptom scores, event-related potential amplitudes, and poorer task performance in the ADHD group further support this notion.Р”Р„ttention-deficit hyperactivity disorder (ADHD) is a frequent neurodevelopmental disorder in children, and recent research has shown that ADHD symptoms persist into adulthood in about 15РІР‚вЂњ65% of childhood cases ( Faraone et al., 2006), with a rate depending on the diagnostic criteria used to define the disorder. There were no significant differences in reaction time (RT) and RT variability between the two groups.Р”В¬onclusion: Our findings show deviations of electrophysiological measures, suggesting reduced effortful engagement of attentional and error-monitoring processes in adults with ADHD. Adults with ADHD also displayed reduced error-related ERN and Pe amplitudes. Also, we observed lower P3 amplitudes in incompatible trials, which were inversely correlated with symptom load in the ADHD group. Results: Adults with ADHD showed higher error rates in incompatible trials, and these error rates correlated positively with the ASRS scores. Adult ADHD Self-Report Scale (ASRS) was used to assess ADHD symptom load. Methods: Fifty-five participants (27 ADHD and 28 controls) aged 19РІР‚вЂњ55 years performed a modified flanker task during EEG recording with 64 electrodes, and the ADHD and control groups were compared on measures of behavioral task performance, event-related potentials of performance monitoring (N2, P3), and error processing (ERN, Pe). To test whether adults with ADHD show persisting deficits and compensatory processes, we investigated performance monitoring during stimulus-evaluation and response-selection, with a focus on errors, as well as within-group correlations with symptom scores. Evidence from neuropsychological, neuroimaging, and electrophysiological studies indicates that alterations of error processing are core symptoms in children and adolescents with ADHD. Introduction: Attention-deficit hyperactivity disorder (ADHD) is one of the most frequent neurodevelopmental disorders in children and tends to persist into adulthood.
