title: [Correlations between changes in hearing and cerebral hemodynamics in patients with chronic alcoholism].
abstract: Seventy eight chronic alcoholics, aged 19 to 50 years, were exposed to audiologic and rheoencephalographic examinations. Tone hearing impairment was found in all subjects. The recruitment or greater than normal increment of loudness was primarily identified in patients of Group 1 that comprised those who consumed alcohol from 1 to 10 years. Rheoencephalographic examinations showed decreases of the rheographic index as well as the tone of large and medium caliber arteries in all patients. Group 2 patients who consumed alcohol for more than 10 years displayed greater changes in the vessel tone than Group 1 patients. Analysis of rheoencephalographic waves demonstrated that peripheral and venous tone was decreased in Group 1 patients and increased in Group 2 alcoholics. Visual analysis of rheoencephalographic waves showed lability in the vessel tone of Group 1 patients and a trend for a vessel spasm in Group 2 patients. The results give evidence that Group 1 chronic alcoholics develop toxic lesions of receptors of the hearing organ which is confirmed by the occurrence of recruitment, sound perception impairment, close to normal speech discrimination and insignificant changes in cerebral hemodynamics. Group 2 alcoholics develop marked disorders in cerebral hemodynamics leading to changes in central and intermediate compartments of the hearing organ.
