Eligible studies needed to use any form of cognitive or psychosocial rehabilitation or treatment for alcohol-related cognitive impairment. In addition, studies were included if they reported experimental manipulations of conditions leading to better performance in alcohol-related brain damage. Studies were excluded if they focused on pharmacological treatments or related to treatment of Wernicke's encephalopathy alone.
Most of the studies focused on memory rehabilitation alone. A smaller number considered executive functioning, mood, other aspects of cognitive functioning, social functioning and improvement in health. Some studies used healthy controls.
The authors stated neither how studies were selected for the review nor how many reviewers performed the selection.
