Frontal lobe atrophy and central motor conduction time in chronic alcoholics

The central motor conduction time (CMCT) was investigated in 12 cases of chronic alcoholism with frontal lobe atrophy, 12 cases of chronic alcoholism without frontal lobe atrophy, and 12 age-matched healthy controls. The CMCT was significantly prolonged in the chronic alcoholics with frontal lobe atrophy as compared to the chronic alcoholics without frontal lobe atrophy and the healthy controls. A significant positive correlation was noted between the CMCT and the degree of frontal lobe atrophy. The CMCT may be prolonged in chronic alcoholics with frontal lobe atrophy.
