[Alcohol-induced cognitive impairment is reversible. Neuropsychological tests but not MRT show improvement after abstinence].

: Of alcoholic patients who underwent MRI (magnetic resonance imaging) of the brain and neuropsychological tests shortly after discontinuation of heavy drinking, a subgroup underwent repeat MRI scans and neuropsychological assessment one year later. The reduction in drinking habits was associated with cognitive improvement but no significant difference in MRI variables including T1-relaxation time.
