Computerized Tomographic Scan Assessment of Alcoholic Brain Damage and Its Potential Reversibility

Abstract

The assessment of alcoholic brain damage by computerized tomographic (CT) scanning is reviewed and discussed. Alcoholics showed greater cerebral atrophy than aged‐matched neurological controls. Supratentorial atrophy measurements correlated significantly with some neurobehavioral assessment measures. The cerebral atrophy reversed in some subjects with maintained abstinence. Computerized assessment of cerebral spinal fluid volume (cerebral atrophy) and mean cerebral density showed decreased cerebral spinal fluid volume and increased cerebral density with maintained abstinence over 4 weeks in a group of 20 alcoholics. CT cerebellar measurements demonstrated atrophy in many subjects, but these measure‐menu did not correlate with measures of ataxia, cognitive impairment, supratentorial atrophy measurements, or age. An example of a magnetic resonance imaging scan of an alcoholic is given. Its advantages in avoiding bony artifact for posterior fossa atrophy estimations and its potential for in vivo description and localization of central nervous system metabolic abnormalities in alcoholism are discussed.
