BACKGROUND AND PURPOSE To examine the neurophysiological basis for the pronounced differences in hyperactivity and impulsiveness that distinguish the predominantly inattentive type of attention-deficit/hyperactivity disorder (ADHD-PI) from the combined type of the disorder (ADHD-C). METHODS Event-related brain responses to a go/no-go test of inhibitory control were measured with functional ma...

Objective: To compare performance of children with attention deficit hyperactivity disorders-combined (ADHD-C) type with control children in multi-source interference task (MSIT) evaluated by means of error related negativity (ERN).Method:We studied 12 children with ADHD-C type with a median age of 7 years, control children were ageand gender-matched. Children performed MSIT and simultaneous re...

background: there have been several studies conducted on the relationship between bipolar mood disorder and attention deficit hyperactivity disorder ( adhd) during the recent years, and in most of them the rate of this association had been estimated as 22-90% and had been reported as noticeable. the goal of this study is to determine the prevalence of adhd in patients with bipolar mood disorder...

OBJECTIVE To determine whether acetyl-L-carnitine (ALC), a metabolite necessary for energy metabolism and essential fatty acid anabolism, might help attention-deficit/hyperactivity disorder (ADHD). Trials in Down's syndrome, migraine, and Alzheimer's disease showed benefit for attention. A preliminary trial in ADHD using L-carnitine reported significant benefit. METHOD A multi-site 16-week pi...

BACKGROUND This study was performed to determine the lifetime prevalence of psychiatric disorders concomitant with attention deficit/hyperactivity disorder (ADHD) among primary school students. METHODS One thousand six hundred fifty-eight primary school students (781 females and 877 males) were selected in a cluster random manner in 2010. The first screening was performed by the Conner's teac...

This study explored various feature extraction methods for use in automated diagnosis of Attention-Deficit Hyperactivity Disorder (ADHD) from functional Magnetic Resonance Image (fMRI) data. Each participant's data consisted of a resting state fMRI scan as well as phenotypic data (age, gender, handedness, IQ, and site of scanning) from the ADHD-200 dataset. We used machine learning techniques t...

It is known that childhood attention-deficit/hyperactivity disorder (ADHD) persists into adulthood. Previous studies have demonstrated that gender, ADHD symptoms, functional impairment severity, medication treatment, IQ, comorbid with oppositional defiant disorder, conduct disorder and follow-up periods were associated with ADHD persistence in longitudinal samples of western population. In this...

Neuroimaging evidences have shown the association of intelligence with several structural brain properties in normal individuals. However, this association for attention deficit hyperactivity disorder (ADHD) is need to be investigated. we estimated grey matter density of the brain using MRI scanning on 56 ADHD individuals comprising 30 combined (age=10.44±2.41, IQ=112.13±13.15, male, 24 right h...
