Abstract:

ENG was just begun to be used to the neurologic diseases in our country. 70 patients with such diseases had been examined with ENG, we found that ENG had a hiqh positive percentagegfor detecting the early changes of vertebro-basilar insufficiency, and suggested that the abnormalities were mainly in the central portions of vestibular system. To encephalitis of brain stem, multiple sclerosis, spinocerebellar degeneration, the EEG changes were central in nature. To vestibuloneuronitis, Menier’s disease etc. it mainfested a peripheral abnormality. So we can conclude that ENG is a valuable method for examining the lesions of Posterior cranial fossa
