title: Increased brain radiodensity in alcoholism. A co-twin control study.
abstract: Significantly increased brain density was found in the frontal lobes and caudate and thalamic nuclei of monozygotic twins who were severely dependent on alcohol when compared with their normal-drinking co-twins. No significant differences in brain radiodensity were found in a group of identical twins who were discordant for less severe alcoholism. Hemispheric differences in brain density were also examined. Right-handed normal twins had greater density in the left caudate than in the right caudate region; this difference was reduced but still present in alcoholics.
