The acute impact that alcohol can have on controlling inhibitions has been well documented in healthy drinkers. On the other hand, there has been little research into the effect of alcohol on individuals with disorders characterized by poor impulse control, such as those with attention-deficit/hyperactivity disorder (ADHD). A study published in a recent issue of Experimental and Clinical Psychopharmacology tested the impact of alchohol on subjects with ADHD (n = 10) and controls (n = 12) using the cued version of the go/no-go task (a measure of implicit social cognition). The task requires quick responses to go targets and suppression of responses to no-go targets following the presentation of cues. Prior research on healthy adults has shown that valid cues can protect against alcohol impairment. Performance was tested under 3 doses of alcohol: 0.65 g/kg, 0.45 g/kg, and 0.0 g/kg (placebo). Alcohol dose-dependently increased inhibitory failures in controls in the invalid, but not the valid, cue condition. By contrast, those with ADHD displayed significant alcohol impairment regardless of cue condition. Thus, unlike controls, valid cues offered little protection from the disinhibiting effects of alcohol in drinkers with ADHD, suggesting an increased sensitivity to alcohol impairment of inhibitory control. The authors conclude that adults with ADHD exhibit an increased sensitivity to alcohol impairment of basic acts of inhibitory control, and this may contribute to the high incidence of impulsive behaviours observed in individuals with this disorder.
