Authors studied the degree of atrophy of alcoholics by measuring ventricle size, cortical sulci size and bifrontal cerebroventricular index. Subjects were consisted of 34 chronic alcoholics and the control group of 25 non-alcoholic neurotics, who were treated at the Department of Neuropsychiatry at Maryknoll Hospital from Mar. 1, 1982 to Aug.8, 1983. The results were as follows: 1. Cerebral atrophy was found among 24 cases (70.Q%) of chronic alcoholics. However, only 1 case of cerebral atrophy was found among the control group. 2. For chronic alcoholics sulci was 6. 64± 1.48mm ventricle size was 17.14±2.37mm and the bifrontal cerebro ventricular index, was 35. 6 ±5.3% , which suggested statistically significant cerebral atrophy, as compared to the control group (p<0,05).
