in the recent years, the coherence index is used in many electroencephalographic studies for investigation of brain connectivity in children with adhd disorder. it is suggested that the coherence is a useful index in discrimination of adhd subjects from normal subjects. however, a few studies are accomplished in subtypes of adhd to identify of differences in functional connectivity between adhd...

adenotonsillar hypertrophy and obstructive sleep disordered breathing can lead to attention deficit/hyperactivity disorder (adhd). the purpose of this study was to evaluate effect of adenotonsillectomy on improvement of adhd symptoms in a quasi-experimental (before and after) study. the efficacy of adenotonsillectomy on improvement of adhd symptoms of 35 children aged 5-12 years with adenotonsi...

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...

conclusions inattentive type and hyperactive-impulsive type of adhd are more prevalent in children with esrd undergoing capd. therefore screening methods for adhd is necessary in these patients. background attention-deficit/hyperactivity disorder (adhd) is the most common childhood psychiatric disorder. this disorder is more prevalent in some chronic disease. objectives the aim of this study wa...

The behavioral difficulties of children with attention-deficit/hyperactivity disorder (ADHD) inattentive type differ from those of children with ADHD combined or hyperactive/impulsive type. Existing evidence-based interventions primarily target the disruptive and impulsive behaviors exhibited by children with ADHD combined and hyperactive/impulsive type. A number of recent advances have been ma...

Previous research investigating attention and impulse control in individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) has largely ignored the symptomatic differences among the three subtypes of ADHD: ADHD-Inattentive Type, ADHD-Hyperactive/Impulsive Type, and ADHD-Combined Type. The present study examined attention and impulse control by focusing on these subtypes. Based on their se...

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...

This study investigated a diverse sample of girls (6-12 years of age) with attention-deficit/hyperactivity disorder (ADHD), combined type (n = 93) and inattentive type (n = 47), plus age- and ethnicity-matched comparison girls (n = 88), who participated in research summer programs. Speech and language problems, grade retention, and adoption characterized the ADHD sample; documented abuse charac...
