    Abstract:
    Chronic alcohol consumption results in considerable damage to many of the body's organs, and particularly to the brain. Beyond the confusional state occurring with acute intoxication or withdrawal, alcohol abuse is responsible of a constellation of neuropsychiatric syndromes including cognitive dysfunction, Wernicke-Korsakoff Syndrome, alcoholic cerebellar degeneration, Marchiafava-Bignami disease and alcohol-related dementia, ARD. ARD would account for nearly 20% of all admissions to state mental hospitals in the United-States. According to the DSM-IV, ARD is defined by a dementia associated with alcohol abuse. However, the concept of a dementia directly related to the neurotoxicity of alcohol for brain neurons is still a matter of debate. Several hypotheses have been proposed to explain the mechanisms of cognitive deficits related to chronic alcohol intoxication. This paper presents the epidemiological, neuropathological, neurochemical and clinical data on ARD. Alcoholism is responsible for cognitive deficits of various severity, which could be reversible or not with alcohol abstinence, but can also participate to the cognitive impairment related to other pathologies, such as Alzheimer disease. On account of this review, it is suggested that the term alcohol-related cognitive impairment should be more convenient than that of ARD, more restrictive and more confusing. Presently, there are no established treatment for alcohol-related cognitive impairment. Alcohol abstinence is a most important step. Psychosocial interventions are essential to support the patients in the daily life.
