Subtle cognitive deficits in severe alcohol addicts--do they show a specific profile?

Although alcohol dependency is a burden to society, data on cognitive performance in therapy-resistant patients after multiple withdrawals are poor. In this study, 22 patients without reported cognitive deficits and 20 control subjects performed extensive cognitive testing and a motor task assessing short-term memory. Patients displayed subtle deficits (mainly in executive function), while memory functions were relatively unimpaired. Our results suggest that subtle frontal-executive deficits may contribute to a poor prognosis, but could be missed by routine clinical tests.
