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… Expand
Attention deficit hyperactivity disorder (ADHD)
Attention deficit hyperactivity disorder (ADHD or AD/HD) is a neurobehavioral developmental disorder, primarily characterized by the co-existence of attention problems and hyperactivity. It affectsExpand
Evaluation of Attention-Deficit Hyperactivity Disorder Risk Factors
TLDR
Findings of the study suggest that maternal and paternal adverse events were associated with ADHD symptoms, but breast feeding is a protective factor. Expand

TLDR
This review addresses the diagnostic difficulties of ADHD and considers some steps that would make ADHD a more easily identifiable disorder. Expand
Attention-deficit hyperactive disorder presenting with school truancy in an adolescent: a case report.
TLDR
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. Expand
Enuresis and Attention Deficit Hyperactivity Disorder (ADHD) in Children and Adolescents Department of Psychiatry
TLDR
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. Expand
Prognostic Factors for Improvement of Attention Deficit Hyperactivity Disorder (ADHD)
TLDR
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. Expand
The effects of risk factors on EEG and seizure in children with ADHD
TLDR
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. Expand
The role of iron deficiency in children with attention deficit/hpyperactivity disorder.
TLDR
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. Expand

  • 2012
TLDR
Findings from structural and functional neuroimaging suggest the involvement of developmentally abnormal brain networks related to cognition, attention, emotion and sensorimotor functions in ADHD, which is confirmed by neurophysiological findings. Expand

Current concepts on the neurobiology of Attention-Deficit/Hyperactivity Disorder
TLDR
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. Expand
Attention deficit disorder: association with familial-genetic factors.
TLDR
The hypothesis that familial-genetic factors are contributory to attention deficit disorder and hyperactivity is supported, and no correlation was found between ADDH and IQ, parental age, years of education, profession, and language spoken at home. Expand
Etiologic Subtypes of Attention-Deficit/Hyperactivity Disorder: Brain Imaging, Molecular Genetic and Environmental Factors and the Dopamine Hypothesis
TLDR
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. Expand
Neurobiology of ADHD
TLDR
How dopamine cell firing activity is normally associated with reinforcing events, and transfers to earlier time-points in the behavioural sequence as reinforcement becomes more predictable, is described and proposed that methylphenidate might act to compensate for the proposed dopamine transfer deficit.

TLDR
Investigations using traditional methods of behavioral genetic analysis impairments have supported a significant role for genetic influences in autism, and patterns of relative risk across relative pharmacological intervention is available that ameliorates all aspects of this condition. Expand
Environmental influences that affect attention deficit/hyperactivity disorder
Three independent complex segregation analyses found that the cause of Attention Deficit/Hyperactivity Disorder (ADHD) was the presence of major genes interacting with environmental influences. InExpand

TLDR
There is strong evidence of genetic involvement in this condition, although a clear-cut mode of inheritance and specific genetic abnormalities are yet to be determined. Expand
Iron deficiency in children with attention-deficit/hyperactivity disorder
TLDR
The results suggest that low iron stores contribute to ADHD and that ADHD children may benefit from iron supplementation. Expand

  • 1996
TLDR
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.
TLDR
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.
