A 21 year-old man presented with a history of sudden onset of aphasia and headache. CT showed a left parietal hypodensity and pallidal calcifications. The ECG showed a Wolff-Parkinson-White's syndrome. The patient then developed successively focal epileptic seizures, temper disorders, a cardiomyopathy, a pepper and salt retinopathy with hemeralopia, a left hemiplegia, deafness, and fever of unexplained origin. Left carotid angiography showed thin, irregular or occluded branches of the middle and anterior cerebral arteries. Blood muscle enzymes, lactate and pyruvate, were elevated with acidosis. Muscle biopsy revealed a mitochondrial myopathy and blood chemistry showed a severe deficiency of respiratory chain enzymes. Death occurred after 28 months. This case showed the diagnostic features of Melas, with some elements of the Kearns-Sayre syndrome. To our knowledge, this is the first case were serial angiographies allowed demonstration of arterial changes capable of explaining cerebral infarctions.

The records of 68 patients with hemoglobin SC disease and 68 age- and sex-matched control patients were reviewed for neurological problems. A significant increase in retinopathy, stupor/coma, and seizures was noted in the hemoglobin SC group. Hemiplegia, noted in two young patients, was probably also secondary to hemoglobin SC disease. Hemoglobin SC disease may often go unrecognized as a cause of stupor and coma in older patients without other obvious manifestations of a sickling hemoglobinopathy. Factors known to precipitate sickling crisis and the associated neurological complications should be avoided, especially in patients undergoing surgery or parturition.
