Attention-deficit/hyperactivity disorder is a neurobiological syndrome with an estimated prevalence among children and adolescents of 5%. It is a highly heritable disorder, but acquired factors in etiology are sometimes uncovered that may be amenable to preventive measures or specific therapy. Early reports have described symptoms similar to attention-deficit/hyperactivity disorder that followed brain trauma or viral encephalitis, and recent MRI studies have demonstrated brain volumetric…

Evaluation of Attention-Deficit Hyperactivity Disorder Risk Factors

Findings of the study suggest that maternal and paternal adverse events were associated with ADHD symptoms, but breast feeding is a protective factor.

Childhood Physical Health and Attention Deficit/Hyperactivity Disorder: A Systematic Review and Meta-Analysis of Modifiable Factors

Light is shed on the importance of physical health in understanding childhood ADHD and possible etiologic links between physical health factors and ADHD are discussed, as are implications for prevention efforts by providers, systems, and communities.

This review addresses the diagnostic difficulties of ADHD and considers some steps that would make ADHD a more easily identifiable disorder.

Attention-deficit hyperactive disorder presenting with school truancy in an adolescent: a case report.

An adolescent who presented to a primary care clinic with school truancy was initially treated for depression with oppositional defiant disorder and sibling rivalry and showed a positive improvement with the use of methylphenidate for his ADHD and escitalopram for his depression.

Enuresis and Attention Deficit Hyperactivity Disorder (ADHD) in Children and Adolescents Department of Psychiatry

It is observed that nocturnal enuresis is a significant and common comorbid condition with ADHD (OR=2.27), and ADHD is associated to a greater probability of lack ofNocturnal sphincter control at 4 years of age [OR: 5.39 95%CI: 3.70–7.86; p<0.05]; this association is both age- and sex-dependent.

Prognostic Factors for Improvement of Attention Deficit Hyperactivity Disorder (ADHD)

The clinical severity of ADHD at baseline, logarithm of dosage of M methylphenidate, and time duration of receiving the Methylphenidate were associated with improvement of ADHD.

The effects of risk factors on EEG and seizure in children with ADHD

History of asphyxia and prematurity do seem to increase the risk of EEG abnormality in patients with ADHD, and modification of these environmental risk factors by evidence-based prevention programs may help to decrease the burden of ADHD.

The role of iron deficiency in children with attention deficit/hpyperactivity disorder.

In conclusion, iron deficiency is an etiologic factor in Attention DeficitHyperactivity Disorder but the severity of the symptoms on admission did not correlate with serum ferritin levels.

Current concepts on the neurobiology of Attention-Deficit/Hyperactivity Disorder

Although not entirely sufficient, changes in dopaminergic and noradrenergic function appear necessary for the clinical efficacy of pharmacological treatments for ADHD, providing support for the hypothesis that alteration of monoaminergic transmission in critical brain regions may be the basis for therapeutic action in ADHD.

Etiologic Subtypes of Attention-Deficit/Hyperactivity Disorder: Brain Imaging, Molecular Genetic and Environmental Factors and the Dopamine Hypothesis

Critical issues about etiologic subtypes of ADHD that may involve dopamine are identified, methods that could be used to address these issues are discussed, and old and new theories that may direct research in this area in the future are reviewed.

Attention‐deficit Hyperactivity Disorder (ADHD), defined as a disorder of awareness with impul‐sivity, has lately been characterized as a dysfunction of the striatum, a structure in a unique position for contextual analysis and samples information from almost the entire cortex through its spiny neurons.

Cytogenetic abnormalities in attention-deficit/hyperactivity disorder.

Blood samples obtained from 100 children with combined type ADHD and normal intelligence are analyzed for the presence of fragile X mutation expansions, the 22q11.2 microdeletion associated with velocardiofacial syndrome, and cytogenetic abnormalities that would be detected with high resolution chromosomal banding.
