Molecular Genetics of Attention-Deficit/Hyperactivity Disorder

TLDR
Family, twin, and adoption studies provide compelling evidence that genes play a strong role in mediating susceptibility to ADHD, and seven genes for which the same variant has been studied in three or more case-control or family-based studies show statistically significant evidence of association with ADHD.

Validity of the executive function theory of attention-deficit/hyperactivity disorder: a meta-analytic review.

TL;DR: Difficulties with EF appear to be one important component of the complex neuropsychology of ADHD, and moderate effect sizes and lack of universality of EF deficits among individuals with ADHD suggest that EF weaknesses are neither necessary nor sufficient to cause all cases of ADHD.

The role of the posterior cingulate cortex in cognition and disease.

TL;DR: A novel model of the posterior cingulate cortex's function is synthesized into a model that influences attentional focus by 'tuning' whole-brain metastability and so adjusts how stable brain network activity is over time, and is tested within the framework of complex dynamic systems theory.

Discovery of the first genome-wide significant risk loci for attention deficit/hyperactivity disorder

Ditte Demontis, +126 more
- 01 Jan 2019 - 
TL;DR: A genome-wide association meta-analysis of 20,183 individuals diagnosed with ADHD and 35,191 controls identifies variants surpassing genome- wide significance in 12 independent loci and implicates neurodevelopmental pathways and conserved regions of the genome as being involved in underlying ADHD biology.
Journal ArticleDOI

SeminarAttention-deficit hyperactivity disorder

TL;DR: Converging evidence from animal and human studies implicates the dysregulation of frontal-subcortical-cerebellar catecholaminergic circuits in the pathophysiology of ADHD, and molecular imaging studies suggest that abnormalities of the dopamine transporter lead to impaired neurotransmission.

Influence of Life Stress on Depression: Moderation by a Polymorphism in the 5-HTT Gene

TL;DR: Evidence of a gene-by-environment interaction is provided, in which an individual's response to environmental insults is moderated by his or her genetic makeup.

Genetic dissection of complex traits: guidelines for interpreting and reporting linkage results

TL;DR: Specific standards designed to maintain rigor while also promoting communication are proposed for the interpretation of linkage results in genetic studies under way for many complex traits.

The BDNF val66met polymorphism affects activity-dependent secretion of BDNF and human memory and hippocampal function

TL;DR: A role is demonstrated for BDNF and its val/met polymorphism in human memory and hippocampal function and it is suggested val/ met exerts these effects by impacting intracellular trafficking and activity-dependent secretion of BDNF.
Journal ArticleDOI

The prevalence and correlates of adult ADHD in the United States: results from the National Comorbidity Survey Replication.

TL;DR: Efforts are needed to increase the detection and treatment of adult ADHD and research is needed to determine whether effective treatment would reduce the onset, persistence, and severity of disorders that co-occur with adult ADHD.

Hyperlocomotion and indifference to cocaine and amphetamine in mice lacking the dopamine transporter

TL;DR: In homozygote mice, dopamine persists at least 100 times longer in the extracellular space, explaining the biochemical basis of the hyperdopaminergic phenotype and demonstrating the critical role of the transporter in regulating neurotransmission.
