PURPOSE Although the relationship between enuresis and psychopathology has been studied intensively, little is known about the prevalence of specific psychiatric disorders. We investigate the prevalence of attention deficit/hyperactivity disorder (ADHD) in children with nocturnal enuresis and correlate these data with clinical subtypes of enuresis/incontinence. MATERIALS AND METHODS A total o...

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent psychiatric disorders in children and adults. While ADHD patients often display circadian abnormalities, the underlying mechanisms are unclear. Here we found that the zebrafish mutant for the circadian gene period1b (per1b) displays hyperactive, impulsive-like, and attention deficit-like behaviors and low levels of dop...

Children with attention deficit hyperactivity disorder (ADHD) are impulsive, inattentive and hyperactive, while children with sensory modulation disorder (SMD), one subtype of Sensory Processing Disorder, have difficulty responding adaptively to daily sensory experiences. ADHD and SMD are often difficult to distinguish. To differentiate these disorders in children, clinical ADHD, SMD, and dual ...

Autism, Pervasive Development Disorder (PDD), Attention Deficit Hyperactive Disorder (ADHD), and Obsessive and Compulsive Disorder (OCD) involve significant frontal and temporal lobe dysfunction. This conclusion is based on NeuroSPECT work now in progress on children afflicted with these disorders. We have been using NeuroSPECT to image cerebral abnormalities of perfusion/function in Autism, AD...

objective: the aim of this study was to examine the differences between adhd subtypes in executive function tasks compared to themselves and normal controls. method: in this study, 45 school aged children with attention deficit hyperactivity disorder (adhd) and 30 normal children who were matched based on age and iq score in wechsler intelligence scale for children-revised (wisc-r) were compare...

introduction executive function define as ability to maintain a suitable and gool directed condition for problem solving. the results of previous studies on tourette syndrome (ts) were contradiction, but the impairment of visual-spatial performance, working memory and reaction time were shown. in children with attention defiat hyperactivity disorder (adhd) impairment of set shifting, motor inhi...

Abstract Background Attention deficit hyperactivity disorder (ADHD) is one of the most common neuropsychological disorders that affects children, adolescents, and adults.
