Covariates of human peripheral nerve function: III. Effects of reported drinking.
Neurotoxicol Teratol 1994 Jan; 16(1):113-122
The effects of reported drinking on the covariates of human peripheral nerve function were investigated in 4,132 Vietnam era veterans using data collected by the Centers for Disease Control as part of the Vietnam Experience Study. Nerve conduction velocity (NCV) and amplitude were measured in the median motor, median sensory, ulnar sensory, peroneal motor, and sural sensory nerves of the dominant limbs of each subject using antidromic stimulation and electromyography. Vibrotactile thresholds and thermal thresholds were measured from the index finger and large toe. Serum liver enzymes were estimated. Questionnaires and interviews were used to estimate alcohol consumption. Data were analyzed using general linear models. Results showed that subjects who reported drinking less than 180 drinks per month had slightly faster mean NCVs, slightly greater evoked response amplitudes, and slightly lower vibrotactile thresholds than those who drank more or did not drink at all. Those who consumed more than 179 drinks per month had slightly slower mean conduction velocities and slightly smaller mean amplitudes than the other drinking categories. There were no consistent associations observable between thermal threshold and alcohol consumption. The authors conclude that even moderately heavy drinking (up to 6 drinks per day) does not cause a slowing of NCV, lessening of the amplitude of the evoked response, or an elevation of sensory thresholds.
