Vestibular system in alcohol and drug addicts.

The study was carried out on 223 alcoholics, 96 drug addicts and 50 healthy persons as a control group. Clinical otolaryngological examination, ENG examination, and audiometry diagnosis were made. The results showed lesions of the central part of the vestibular system in alcohol and drug addicts which are much more evident on ENG examination than in clinical otolaryngological findings. We have observed that trauma capitis does not cause increased vestibular disturbances in addicted persons. Audiologic findings indicate significant hearing loss in both groups.
