There are several lines of evidence suggesting that the nicotinic system may be functionally significant in ADHD: (a) nicotine promotes the release of dopamine and has been shown to improve attention in adults with ADHD, smokers and non-smokers; (b) ADHD is a significant risk factor for early initiation of cigarette smoking in children; (c) maternal cigarette smoking appears to be a risk factor for ADHD; (d) animal studies in rats and monkeys also suggest that nicotine may be involved in attentional systems and locomotor activity; and (e) a central nicotinic agonist, ABT-418, improves attention in both monkeys and ADHD adults. The current study examined the alpha 4 receptor, one of the sites of action of ABT-418. A known Cfol polymorphism within the nicotinic acetylcholine alpha 4 receptor gene, CHRNA4, was studied in 70 ADHD parent-proband trios from an ongoing sample collection of children aged 6-12 with ADHD, according to DSM-IV criteria. Children with known major medical or psychiatric conditions or mental retardation (IQ < 70) were excluded from the study. The Transmission Disequilibrium Test demonstrated no evidence that variation at the nicotinic acetylcholine alpha 4 receptor Cfol polymorphism influences susceptibility to ADHD (P > 0.35). The continuing sample collection will enable further study of other potential nicotinic system polymorphisms in ADHD in more powerful samples."xsd:string |
