Alcohol-induced brain damage and liver damage in young males.

37 alcoholic males under the age of 35 were examined clinically, by psychometric tests, by computerised tomography (CT scans), and by liver biopsy. Factors other than alcoholism that might have caused brain damage were excluded. The prevalence of brain damage in this group was far greater than that of severe liver damage: 59% were intellectually impaired and 49% had cerebral atrophy on CT scan, whereas only 19% had cirrhosis. There was no significant correlations between the degree of liver damage and the degree of intellectual impairment (p greater than 0-05), nor between the degree of intellectual impairment and the presence of cerebral atrophy. The CT scan is an inadequate measure of functional brain damage, psychometric testing is preferable. Other neurological complications of alcoholism were not impressive. Disabling intellectual impairment may be the earliest complication of chronic alcoholism and may arise early in the alcoholic career.
