To assess the effects of chronic alcohol ingestion on the faster and slower nerve fibers (alpha fiber group) in the peripheral nervous system, the distribution of nerve conduction velocities (DCV) and conventional maximal motor and sensory nerve conduction velocities (MCV and SCV) in the median nerve were measured in 23 male patients with severe alcoholic dependency (DSM-III-R), aged 30-64 (mean, 50) years, and in 23 age-matched healthy men. The DCV was expressed by the conduction velocities below which 10, 20,..., 80, and 90% of active fibers lie (V10, V20,..., V80, and V90 velocities). The V40 to V90 velocities of the DCV were significantly slower in the alcoholics than in the control subjects; the SCV and MCV in the alcoholics were also significantly slowed. These findings suggest that the faster large myelinated nerve fibers are more sensitive to chronic alcohol ingestion than the slower large myelinated nerve fibers.

D008297 Male Males
D008475 Median Nerve A major nerve of the upper extremity. In humans, the fibers of the median nerve originate in the lower cervical and upper thoracic spinal cord (usually C6 to T1), travel via the brachial plexus, and supply sensory and motor innervation to parts of the forearm and hand.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D000437 Alcoholism A primary, chronic disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. The disease is often progressive and fatal. It is characterized by impaired control over drinking, preoccupation with the drug alcohol, use of alcohol despite adverse consequences, and distortions in thinking, most notably denial. Each of these symptoms may be continuous or periodic.
