Abstract:
Objective To explore the value of blink reflex (BR) and brainstem auditory evoked potential (BAEP) in the diagnosis of multiple sclerosis (MS). Methods Totally 20 normal persons and 32 MS patients were examined with BR and BAEP respectively.Results 32 MS patients were divided into two groups according to the abnormalities localized to the brainstem: the symptomatic group and the asymptomatic group. The abnormal rates of BR in two groups were 85.7% and 50.0% respectively. The abnormal rates of BAEP in the two groups were 71.4% and 44.4% respectively. The abnormal rates of BR in Ⅴand Ⅶ cranial nerves were both 21.9%. The abnormal rates of BR,BAEP,BR and BAEP in finding out lesions of brainstem were 65.6%,56.3% and 75.0% respectively.Conclusions Subclinical lesions in brainstem, Ⅴand Ⅶ cranial nerves were demonstrated by BR. The combined abnormal rate of BR and BAEP was higher than either test alone.
