OBJECTIVE In children with attention-deficit/hyperactivity disorder (ADHD), an increased theta/beta ratio in the resting EEG typically serves as a rationale to conduct theta/beta neurofeedback (NF) training. However, this finding is increasingly challenged. As NF may rather target an active than a passive state, we studied the EEG in a condition that requires attention. METHODS In children wi...

OBJECTIVE Attention deficit hyperactivity disorder (ADHD) is a common, complex and highly heritable disorder, characterised by inattentive, impulsive and overactive behaviour. Evidence for the heritability of ADHD measures in twin population samples has come from the analysis of total scores that combine inattentive and hyperactive-impulsive symptoms subscales. This study investigated, in a com...

ADHD is one of the most widely studied conditions in schoolage children, and a major reason for referral to health care services due to the multidimensional nature of the impairment experienced by patients with this disorder [1]. The prevalence of ADHD in the pediatric population is estimated to be 7% [2]. ADHD is characterized by symptoms of inattention, hyperactivity and impulsivity, with ons...

This study evaluated the social perception and social functioning of children with Attention Deficit Hyperactivity Disorder-Combined (ADHD-C), ADHD-predominately inattentive (ADHD-PI), and controls. Two-hundred and seventy children with ADHD-C, ADHD-PI, or controls were evaluated using direct and indirect measures of social functioning. The ADHD-C and ADHD-PI groups showed significant differenc...

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...

The prevalence of attention-deficit/hyperactivity disorder (ADHD) has been estimated at 3-7% in the population. Children with this disorder are often characterized by symptoms of inattention and/or impulsivity and hyperactivity, which can significantly impact on many aspects of their behaviour and performance. This study investigated the characteristics of the SWAN Rating Scale and its discrimi...

Objectives: This study performed a statistical analysis comparing adolescents with Attention Deficit Hyperactive Disorder (ADHD) and a control group in the Conners’ Continuous Performance Test (CCPT) 5 factor model, proposed by Egeland and Kovalick-Gran (2010a). Methods: The clinical group was composed by 28 participants with ADHD (17 male). The adolescents were divided in two groups regarding ...

This is the first study to evaluate ADHD-hyperactive/impulsive subtype in a large clinical sample of adults with ADHD. The Quality of Life, Effectiveness, Safety and Tolerability (QuEST) study included 725 adults who received clinician diagnoses of any ADHD subtype. Cross-sectional baseline data from 691 patients diagnosed with the hyperactive/impulsive (HI), inattentive (IA) and combined subty...

Attention-deficit hyperactivity disorder (ADHD) is a complex neurodevelopmental disorder that implies several-step process, and there is no single test to diagnose both ADHD and associated comorbidities, such as oppositional-defiant disorder (ODD), anxiety disorder, depression, and certain types of learning disabilities. The purpose of the present study was to examine correlations between behav...
