前颞叶和海马切除治疗难治性颞叶癫痫对认知功能影响的研究

目的 探讨前颞叶和海马切除治疗难治性颞叶癫痫对认知功能的影响.方法 19例难治性颞叶癫痫患者接受前颞叶和海马切除手术,手术前和手术后3、6月进行认知神经心理学测评以了解认知功能的变化.结果 19例难治件颞叶癫痫患者接受了前颞叶和海马切除术后取得了良好的疗效,术后1例有-过性的言语障碍,2例有-过性的欣快等精神症状.难治性颞叶癫痫患者存在严重的认知功能障碍(特别是智力、注意力、记忆功能障碍),前颞叶和海马切除手术没有加重认知功能障碍.在手术后6月一些认知功能反而有改善的趋势.结论 难治性颞叶癫痫患者存在认知功能障碍,采用前颞叶和海马切除能治愈或减少颞叶癫痫发作,并且对认知功能障碍有一定的改善作用.

Effect of surgical excision of the anterior temporal lobe and hippocampus on the cognitive function of patients with refractory temporal lobe epilepsy

Objective To evaluate the effect of surgical excision of the anterior temporal lobe and hippocampus on the cognitive function of patients with refractory temporal lobe epilepsy. Methods Nineteen patients with refractory temporal epilepsy received surgical excision of the anterior temporal lobe and hippocampus, and cognitive neuropsychologieal assessments were conducted, 3 and 6 months after the surgery, to evaluate the changes in the patinets' cognitive functions. Results Satisfactory effects were achieved in these patients after the operations. One patient showed temporary speech disorder, and two exhibited temporary euphoria. Patients with refractory temporal lobe epilepsy had severe cognitive dysfunctions involving especially in the intelligence, attention and memory, which were not aggravated after the operation, Conversely, the operation resulted in gradual improvement of some of the cognitive functions in these patients. Conclusion Patients with refractory temporal lobe epilepsy have cognitive dysfunction, and surgical excision of the anterior temporal lobe and hippocampus can cure or reduce seizure of temporal lobe epilepsy and improve the cognitive dysfunctions to some extent.
