A significant number of patients with epilepsy fail to respond to currently available antiepileptic drugs. This suggests a need for alternative approaches to reduce the occurrence of seizures in these patients. Recent data have shown that in addition to well-known neuronal mechanism, seizures may be a consequence of misguided inflammatory response and blood-brain barrier disruption. Both peripheral and brain proinflammatory events have been demonstrated to govern the onset of status epilepticus. Evidence deriving from the experimental and clinical realms supports the notion that a role for proinflammatory and cerebrovascular events in seizure disorders is broader than previously suspected. As a result, methods to pharmacologically reduce blood-brain barrier permeability and reduce inflammation have emerged as means to reduce seizure burden. For instance, corticosteroids have been shown to be beneficial and the same agents may be able to further reduce seizure burden in conjunction with currently prescribed antiepileptic drugs.
相当数量的癫痫患者对目前可用的抗癫痫药物没有反应。这表明需要采用替代方法来减少这些患者的癫痫发作。最近的数据表明,除了众所周知的神经元机制外,癫痫发作可能是错误的炎症反应和血脑屏障破坏的结果。已经证明外周和脑内的促炎事件可以控制癫痫持续状态的发作。来自实验和临床领域的证据支持这样一种观点,即促炎和脑血管事件在癫痫发作中的作用比以前怀疑的更为广泛。因此,出现了一些药理学方法来降低血脑屏障通透性和减少炎症,以减轻癫痫发作的负担。例如,皮质类固醇已被证明是有益的,并且相同的药物可能能够与目前规定的抗癫痫药物一起进一步减轻癫痫发作的负担。
