Alcohol use disorders in cognitively impaired patients referred for geriatric assessment

Alcohol Use Disorders are thought to be underdiagnosed in the geriatric population. A retrospective medical record review was performed on 383 patients who presented for outpatient geriatric assessment from 1985-1990. The record review included data on the alcohol consumption history, age, sex, presence of alcoholic beverages in the home, geriatric psychiatry evaluation, and alcohol-related diagnoses. Alcohol Use Disorders were recognized as contributing to medical problems in 10% of patients having a mean age of 78 years. All except one patient were found to be cognitively impaired. In addition, 9% of patients consumed alcohol on a regular basis and this consumption was not considered in the diagnosis, despite the presence of cognitive impairment. Twenty-five percent of cognitively impaired patients were consuming alcohol at the time of evaluation. These results indicate that alcohol consumption and AUD are common in cognitively impaired patients presenting for geriatric assessment. Recognition of Alcohol Use Disorders is essential, as chronic alcohol toxicity represents one cause of potentially reversible dementia. Because there are no validated instruments for alcoholism screening in cognitively impaired elderly patients, evaluation should include a past and present consumption history, a search for alcoholic beverages at the home visit, and possible psychiatric referral.
