Epilepsy in a patient with ataxia caused by vitamin E deficiency.
Ataxia due to vitamin E deficiency is important because disease progression can be stopped by supplementary therapy. A limited number of studies and case series suggest that the disease is mainly confined to the cerebellum and spinal cord tract and seems to be more common in North African countries. We report a patient from North Norway with progressive ataxia from the age of 5, bilateral dropfoot, Babinski's sign, dysarthria and early epilepsy. Two mutations, 513insTT and p.Arg134x, were detected. When treatment was initiated 25 years after onset of symptoms, the patient was bound to the wheel chair. No further progression of pareses, ataxia or epileptic seizures has been observed in a 3-year follow-up period. This case indicates that cerebral involvement may be present in patients with a lack of vitamin E. If this observation is confirmed, a further exploration of clinical presentation, anatomic involvement and geographic distribution of the disease is warranted.
