Reversability of Alcohol-Induced Dementia

There is demonstrated gradual improvement of cognitive ability with prolonged abstinence.[22] However, in an apparently clinically healthy population of abstinent alcohol-dependent subjects, deficient verbal and nonverbal abstraction, along with altered visuo-motor coordination, learning, and memory have been reported to persist despite prolonged periods of abstinence.[26] Such deficits in executive functioning, learning, and concentration may to lead to poor treatment outcomes even in alcohol-dependent individuals who appear to be healthy and wish to limit their drinking.
