A random sample of 241 patients from General Practice registers in London were interviewed to assess alcohol consumption, cognitive impairment, depression and other factors. Fifty-one per cent of men and 22% of women reported use of alcohol in the previous 3 months. No significant association was found between reported drinking status and age, score on a depression scale, falls in the previous 3 months, attendance at outpatient clinics or inpatient care in the previous year. In the men abstainers were significantly more likely to show cognitive impairment than were drinkers. Amongst those respondents who admitted to drinking within the previous 3 months, total stated weekly alcohol consumption was not associated with age, cognitive impairment and scores on the depression scale, and there was no association with falls, or with outpatient or inpatient care. Only three men (3.6%) and five women (3.2%) admitted consuming more than 21 and 14 units of alcohol per week, respectively.
