目的：分析迟发脑病临床表现、脑电图及CT改变特征、影响预后的因素。方法：对35例迟发脑病临床表现、脑电图、CT改变进行比较分析。结果：迟发脑病．植物神经功能紊乱、痴呆、精神障碍及震颤麻痹综合征多见，CT显示以苍白球、皮层下白质低密度改变为主，临床表现、脑电图与CT改变并不完全一致。以植物神经功能紊乱、精神障碍、痴呆为主者预后佳，去皮层状态预后差。急性中毒昏迷时间、头颅CF改变严重程度与预后密切相关（P＜0．05或P＜0．01）。结论：昏迷时间、临床特征、CT改变对判断预后有较重要的参考价值。
Objective: To analyze the clinical manifestations of delayed encephalopathy, EEG and CT changes in the characteristics of prognostic factors. Methods: 35 cases of delayed encephalopathy clinical manifestations, EEG, CT changes were compared. Results: Delayed encephalopathy. Autonomic dysfunction, dementia, mental disorders and paralysis syndrome more common, CT showed globus pallidus, cortical white matter low density changes mainly clinical manifestations, EEG and CT changes are not exactly the same. With autonomic dysfunction, mental disorders, dementia-based prognosis is good, poor prognosis of the cortical state. Acute poisoning coma time, the severity of head CF changes and prognosis are closely related (P <0.05 or P <0.01). Conclusion: The coma time, clinical features and CT changes have important reference value in judging the prognosis.
