Researchers link alcohol-dependence impulsivity to brain anomalies

Researchers already know that alcohol dependence (AD) is strongly associated with impaired impulse control or, more precisely, the inability to choose large, delayed rewards rather than smaller but more immediate rewards. Findings from a study using functional magnetic resonance imaging (fMRI) to investigate the neural basis of impulsive choice among individuals with alcohol use disorders (AUDs) suggest that impulsive choice in AD may be the result of functional anomalies in widely distributed but interconnected brain regions that are involved in cognitive and emotional control.
