Preferential transmission of paternal alleles at risk genes in attention-deficit/hyperactivity disorder.
Family, twin, and adoption studies have demonstrated a significant genetic contribution to the etiology of attention-deficit/hyperactivity disorder (ADHD). Pharmacological, neuroimaging, and animal-model findings suggest imbalances in monoaminergic (dopaminergic, serotonergic, and noradrenergic) neurotransmission in ADHD. We have examined monoaminergic candidate genes for possible genetic assoc...
متن کاملAssociation study of a SNAP-25 microsatellite and attention deficit hyperactivity disorder.
Several lines of evidence implicate synaptosomal-associated protein of 25 kDa (SNAP-25) in the etiology of attention deficit hyperactivity disorder (ADHD). Most notably, the coloboma mouse mutant, considered to be a good animal model of hyperactivity, has a deletion spanning this gene. Introducing a SNAP-25 transgene into these animals alleviates hyperlocomotion. We have identified a novel micr...
متن کاملAssociation of SNAP-25 Gene Ddel and Mnll Polymorphisms with Adult Attention Deficit Hyperactivity Disorder
OBJECTIVE The synaptosomal-associated protein of 25 kDa (SNAP-25) gene is a presynaptic plasma membrane protein and an integral component of the vesicle docking and fusion machinery mediating secretion of neurotransmitters. Previously, several studies reported association between SNAP-25 and attention deficit hyperactivity disorder (ADHD). We investigated whether these SNAP-25 polymorphisms (Mn...
متن کاملSuicide risk in attention-deficit/hyperactivity disorder.
BACKGROUND ADHD (Attention-deficit/hyperactivity disorder) is a common neurodevelopmental disorder that manifests itself during childhood with various combinations of symptoms, including inattention, hyperactivity and impulsivity. Research has shown that psychiatric comorbidities play an important role in the development of suicidal behavior and, recently, there has been a growing interest in a...
متن کاملAttention-deficit hyperactivity disorder.
Attention-deficit hyperactivity disorder (ADHD) affects between 1.4% and 6% of children. The importance of the role of primary care in the recognition and joint management of this disorder is being increasingly highlighted. Despite a wealth of research, the diagnosis and management of ADHD have attracted a good deal of controversy. In this discussion paper, we focus on the empirical basis for s...
