The clinical neurological and electroneuromyographycal examination were performed in 75 patients with chronic alcoholism including 15 patients with abstinence (withdrawal) syndrome. The abstinence period without any alcohol consumption did not last more that 6 days before observation time. The clear, specific neurological symptoms were revealed in alcohol abstinence syndrome (AAS), exactly: the general brain disturbances in the form of headache, dizziness, horizontal small-swinging nystagmus, dynamic ataxia, the increase of tendinous reflexes preferentially from upper limbs, the tremor of head, tongue and of streched out arms fingers, the sympathic adrenal type vegetative disturbances. The increase of impulse conduction rate along the median nerve as well as elevation of craniocaudal coefficient and neuromuscular conduction disturbances were also characteristic for AAS.
