Background and objective: Alcoholism is common and serious problem. Alcohol most commonly consumed in the form of ethanol. The effects of alcohol are mainly caused by altering the function of membrane proteins in many different cell types especially cells of GIT, urinary tract, cardiovascular and nervous system. Alcohol also causes alcoholic peripheral neuropathy. Reaction time has physiological significance and is simple and non invasive test to see the functions of peripheral as well as central neural structures. The reaction time is an indirect index of processing capability of central nervous system and also a simple means for sensory and motor performance for early diagnosis of alcoholic neuropathy. Hence we want to investigate the audiovisual reaction time in alcoholic subjects. Material and Methods: The study was conducted in the department of physiology MR Medical College Gulbarga. The study was conducted in chronic alcoholic’s subject and there age matched control and in three groups of 30 subjects in each groups. Group I – Normal healthy control, Group II – chronic alcoholic without neuropathy, Group III – chronic alcoholic with neuropathy Audiovisual reaction time was determine by using an instrument “ Reaction time apparatus” designed by Anand agencies Pune. The data was statistically analyses by using student unpaired‘t’ test.Result: auditory and visual reaction time was compared with chronic alcoholic and healthy aged matched controls. The reaction time was significantly increased in chronic alcoholic without neuropathy and with neuropathy. Conclusion: From our study we conclude that alcohol addiction has adverse effect on the audiovisual reaction time. Thus helps in early diagnosis as well as prognosis of alcoholic neuropathy
