尿毒症性脑病近年有增多之势(患病率为13～86％),本组33例报告如下。 1 先兆及症状 尿毒症性脑病多数起病隐伏缓慢,先兆有:疲乏无力,头晕头重,目眩头痛,情绪低落或内在焦虑,言语减少,行动缓慢,耐久性差注意力分散,记忆力减弱,思考迟钝,计算失误等症状,但这些症状波动性大,对此要有高度的警惕。症状主要有:焦虑易怒,失眠,嗜睡,对周围环境和自身感觉失调。扑翼样震颤是诊断本病的重要体征。脑电图检查常出现α节律失常,低电压,多数病人以弥漫性漫波为主,少数病人为高振幅慢波和锐波。近期据A—Lbeftazzi和Rizz二氏研究本症脑电图上可见到Ⅱ ⅢV波的潜伏时限延长,Ⅰ—Ⅱ、Ⅲ—V、Ⅰ—V,分别达到顶点的潜伏时限延长。
Uremic encephalopathy in recent years increased tendency (prevalence rate of 13 ~ 86%), the group of 33 cases reported as follows. 1 aura and symptoms of uremic encephalopathy most of the onset of latent slow, the precursors are: fatigue, dizziness, headache, depression or internal anxiety, speech loss, slow action, poor durability distracted, memory loss, slow thinking , Calculation errors and other symptoms, but the volatility of these symptoms, which should have a high degree of vigilance. Symptoms are: anxiety irritability, insomnia, drowsiness, the surrounding environment and their own sense of disorder. Asterixis tremor is an important sign of diagnosis of the disease. EEG often appear alpha rhythm disorders, low voltage, diffuse diffuse majority of patients with the majority of patients, a small number of patients with high amplitude slow wave and sharp wave. According to A-Lbeftazzi and Rizz’s recent study of EEG on the electroencephalogram Ⅱ Ⅱ V latency can be seen to extend the latency, Ⅰ-Ⅱ, Ⅲ-V, Ⅰ-V, respectively, to reach the peak latency extension.
