Differences between the subtypes of Attention Deficit Hyperactivity Disorder (ADHD) continue to have a place in the clinical and research literature. The purpose of this study was to examine differences specific to academic and executive function deficits in a sample of 40 children, aged 9-15 years. Although there was a tendency for the Predominantly Inattentive (PI) group to evidence lower per...

The objective of this study was to examine the relation between the 5, 10-methylenetetrahydrofolate reductase (MTHFR) gene and behaviors related to attention- deficit/hyperactivity disorder (ADHD) in individuals with myelomeningocele. The rationale for the study was twofold: folate metabolizing genes, (e.g. MTHFR), are important not only in the etiology of neural tube defects but are also criti...

  Background :Attention Deficit Hyperactivity Disorder (ADHD) is the most common childhood neurological disorder. This disorder is more prevalent in some chronic diseases. The aim of this study was to investigate ADHD in children with early stages of chronic kidney disease (CKD) and to compare it with healthy children.   Methods : Seventy five 5-16-year-old children with early stages of CKD (st...

Deletions encompassing the X-linked STS gene (encoding steroid sulfatase) have been observed in subjects with neurodevelopmental disorders, including attention deficit hyperactivity disorder (ADHD). Recently, two single nucleotide polymorphisms (SNPs) within STS (rs12861247 and rs17268988) have been reported to be associated with ADHD risk and inattentive symptoms in ADHD, respectively. Using a...

Objectives: The aim of the study was to determine the prevalence of attention deficit hyperactivity Disorder (ADHD) and associated risk factors among children were attended the general pediatric outpatient clinic of Menoufia University Hospital. Background: Attention deficit hyperactivity disorder is the most commonly seen developmental disorders, with significant impacts on the child's social,...

OBJECTIVE 342 Caucasian subjects with attention deficit/hyperactivity disorder (ADHD) were recruited from pediatric and behavioral health clinics for a genetic study. Concurrent comorbidity was assessed to characterize the clinical profile of this cohort. METHODS Subjects 6 to 18 years were diagnosed with the Schedule for Affective Disorders & Schizophrenia for School aged Children (K-SADS-P ...

BACKGROUND Very preterm (VP) children are at particular risk for attention deficit/hyperactivity disorder (ADHD) of the inattentive subtype. It is unknown whether the neurodevelopmental pathways to academic underachievement are the same as in the general population. This study investigated whether middle childhood attention or hyperactivity/impulsivity problems are better predictors of VP adole...

OBJECTIVE To psychometrically evaluate a new parent-completed questionnaire that measures the effect of attention-deficit/hyperactivity disorder (ADHD) on the everyday well-being of children and their families. SETTING Using a mail-out/mail-back method, the sample was drawn from the registry of an outpatient developmental and behavioral program of a large tertiary pediatric hospital. All chil...

OBJECTIVE OROS methylphenidate HCL (MPH) is a recently developed long-acting stimulant medication used to treat attention-deficit/hyperactivity disorder (ADHD). This study was conducted to examine dosage effects on ADHD symptoms and stimulant side effects and to explore potential moderating effects of ADHD subtype. METHODS Children with ADHD combined type (ADHD-CT) or predominantly inattentiv...
