title: Usefulness of BAER studies in the early diagnosis of Pelizaeus-Merzbacher disease.
abstract: Brainstem auditory evoked responses (BAERs) were markedly abnormal in a 1-month-old infant with Pelizaeus-Merzbacher disease. Wave II occurred at a prolonged latency, and all of the following waves were absent bilaterally. BAER is useful for early diagnosis in this disease.
