Alcohol and cognitive impairment

Abstract

The relationship between alcohol use and cognitive impairment has been notoriously difficult to disentangle. We present what is known about cognitive impairment associated with alcohol use/misuse, covering the spectrum from mild and subtle cognitive change through to severe alcohol-related brain damage, including Wernicke-Korsakoff syndrome. We highlight aids to the diagnosis and management of these conditions, and emphasise the benefits of prompt treatment on outcome. We also review progress in understanding their neurobiology. Suggestions for possible service configuration based on both our clinical practice and national guidelines are given.
