Brain damage and neuronal loss caused by traumatic brain injury, ischemic stroke, and symptomatic status epilepticus can lead to severe long-term consequences, such as impairment in learning and memory and cognitive functions, and development of chronic epilepsy. This can be the result of morphologic and functional changes underlying temporal lobe epilepsy. Epilepsy patients have increased risk of status epilepticus. It is a life-threatening condition when seizures last for more than 30 min and trigger processes leading to neuronal apoptosis and necrosis in various parts of brain. Administration of neuroprotective drugs preventing these pathologic processes could improve the prognosis for such patients. However despite of active research of neuroprotective drugs, the effective ways to prevent brain damage resulting from prolonged seizures are yet to be found. Studies of neuroprotective properties of classic and novel anticonvulsant drugs showed that most of them do not have the sufficient neuroprotective effect and are not able to prevent epileptogenesis. Thus the studies of other potential neuroprotective drugs seem to be promising.
创伤性脑损伤、缺血性中风和症状性癫痫持续状态所导致的脑损伤和神经元丢失会引发严重的长期后果,例如学习与记忆以及认知功能受损,还有慢性癫痫的发展。这可能是颞叶癫痫潜在的形态学和功能变化所致。癫痫患者发生癫痫持续状态的风险增加。当癫痫发作持续超过30分钟并引发导致大脑各部位神经元凋亡和坏死的过程时,这是一种危及生命的状况。给予能够预防这些病理过程的神经保护药物可能会改善此类患者的预后。然而,尽管对神经保护药物进行了积极研究,但尚未找到预防长时间癫痫发作所致脑损伤的有效方法。对经典和新型抗惊厥药物神经保护特性的研究表明,它们中的大多数没有足够的神经保护作用,无法预防癫痫发生。因此,对其他潜在神经保护药物的研究似乎很有前景。
