Alcohol and impulsivity can be a toxic mix, researchers reported.
In a long-running, prospective cohort study among people seeking help for alcohol-related problems, those with poor impulse control had an increased risk of dying, according to Daniel Blonigen, PhD, and colleagues at the Palo Alto Veterans Affairs Medical Center in Palo Alto, Calif.
The effect was independent of the risk associated with alcohol use disorders, Blonigen and colleagues reported online in Alcoholism: Clinical and Experimental Research.
Both impulsivity and alcohol use disorders are known to increase the risk of premature death, the researchers noted, and alcohol use increases impulsive behavior. But there has been no research on how poor impulse control affects mortality risk among people who also have problems with alcohol, they added.
