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.
维生素E缺乏所致共济失调很重要,因为补充治疗可阻止疾病进展。少数研究和病例系列表明,该病主要局限于小脑和脊髓束,且在北非国家似乎更为常见。我们报告了一名来自挪威北部的患者,从5岁起出现进行性共济失调、双侧足下垂、巴宾斯基征、构音障碍和早期癫痫。检测到两个突变,即513insTT和p.Arg134x。症状出现25年后开始治疗时,患者只能依靠轮椅行动。在3年的随访期内,未观察到瘫痪、共济失调或癫痫发作有进一步进展。该病例表明,维生素E缺乏患者可能存在脑部受累情况。如果这一观察结果得到证实,则有必要进一步探索该病的临床表现、解剖学受累情况及地理分布。
