Biochemical studies and therapy in subacute necrotizing encephalomyelopathy (Leigh's syndrome)

The clinical course, biochemical abnormalities, and the effects of vitamin therapy in subacute necrotizing encephalomyelopathy are described in a patient who was serially evaluated from birth. Important features include increased cerebrospinal protein, elevated blood lactic acid values, and abnormal macular morphology detected when the patient was asymptomatic. Renal tubular acidosis and alaninemia were noted shortly after the onset of symptoms....
