[Clinical, CT and electrophysiologic studies of alcoholics with special reference to the cerebellum].

Comprehensive clinical examinations and laboratory investigations were carried out in 20 alcoholics (Group III according to Jellinek's classification) with particular reference to the cerebellum. Clinical cerebellar signs were found in 4 cases, and in 3 of them atrophic changes of the cerebellum and cerebrum were demonstrated in CT examinations, and in 3 electrophysiological changes compatible with neuropathy were found. Evoked auditory potential from the brainstem was changed in 12 cases, which might be explained as impairment of the cerebellar function. In 12 cases signs of polyneuropathy were disclosed, in 5 of them they were evident clinically and electrophysiologically, and in 7 they were found only in EMG. Changes in somatosensory and visual evoked potentials were less evident, but in connection with abnormalities in other investigations they suggested presence of diffuse or disseminated nervous system damage. These investigations suggest that cerebellar signs in alcoholics are not isolated and are a manifestation of a more generalized damage to the nervous system.
