We studied three patients with metachromatic leukodystrophy, two with late infantile onset and one with juvenile onset. Auditory brainstem responses were abnormal in all patients, including a 14-month-old child who was asymptomatic, with normal neurologic examination and peripheral nerve conduction studies. Auditory brainstem responses therefore indicated early pathology. A new high-performance liquid chromatography assay was used to quantitate the urinary sulfatide excretion at the picomole level.
