脑部感染所致抽搐中枢神经系统感染是痫性发作的重要病因。抽搐可以发生在疾病的过程中,也可晚发于疾病后的几年。急性期引起抽搐的原因可由于局限性的皮层静脉或动脉的闭塞;细菌性毒素、发热、电解质平衡障碍、脑水肿等导致神经细胞内外化学环境的改变、破坏了细胞膜的稳定性。晚发者系由于炎症后的瘢痕。感染可以是细菌性、寄生虫性、病毒性或螺旋体性脑 Convulsions caused by brain infection CNS infection is an important cause of seizures. Convulsions can occur during the disease, but also late in the years after the disease. Acute convulsions may be due to the limitations of the cortical veins or occlusion of arteries; bacterial toxins, fever, electrolyte imbalance, brain edema and other chemical and biological changes inside and outside the nerve cells, undermining the stability of the cell membrane. Late-onset due to inflammation of the scar. The infection can be bacterial, parasitic, viral or spirochete
