    Visual evoked responses (VER) are more effective than auditory evoked responses (ABR) for diagnosing multiple sclerosis (MS). VER detected abnormalities in all patients, while ABR only found them in 9 out of 16.

    Area of Science:

    • Neuroscience
    • Clinical Neurology

    Background:

    • Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system.
    • Brainstem lesions are common in MS and can be detected using neurophysiological tests.

    Purpose of the Study:

    • To compare the diagnostic utility of visual evoked responses (VER) and auditory evoked responses (ABR) in patients with clinically definite multiple sclerosis.
    • To determine the most effective evoked response method for establishing an MS diagnosis.

    Main Methods:

    • Sixteen patients meeting criteria for clinically definite MS were evaluated.
    • Both visual evoked responses (VER) and auditory evoked responses (ABR) were performed on all participants.
    • Results from VER and ABR were compared.

    Main Results:

    • All 16 patients exhibited abnormal VER.
    • Abnormal ABR were observed in 9 out of the 16 patients.
    • A higher sensitivity for detecting lesions was noted with VER compared to ABR.

    Conclusions:

    • Visual evoked responses (VER) demonstrate superior efficacy in diagnosing multiple sclerosis.
    • VER is the recommended neurophysiological method for establishing an MS diagnosis due to its higher detection rate of abnormalities.
