在肺炎时可见脑病症状,有时为脑血液循环障碍。作者在300例大叶性和局灶性肺炎中见到12例具有卒中特征的脑血液循环障碍。患者42～18岁,9例经尸解证实,6例在高血压合并全身和脑动脉硬化基础上发生脑血液循环障碍。急性肺炎的脑血液循环障碍的过程是严重的,其特征是弥散性侵犯广泛的皮层区、皮质下部和脑干。急性肺炎有大脑半球卒中时,脑电图可在弥散性改变的背景上出现固定的局限性改变,在右额—颞呈现多数高波幅慢波。治疗后神经病症状缓解,脑电图复常。在脑深部结构损害时脑电图改变具弥散性特征,呈爆发双侧对称性高波幅慢波,伴半球间不对称,此系间-中脑结构机能改变所致。这说明脑生物电活动障碍的程度反映了急性肺炎时脑卒中临床征象的严重性,及其病变部位。急性肺功能不全伴大脑不同部位局灶损害的脑血液循环障碍,其轻瘫肌肉的肌电图改变为:上下肢“静止”时电活动降低或增高,同由大脑局灶损害所致的肌张力降低或增高相一致;被动和协同运动时生物电活动增加;最大用力时,生物电活动降低和曲线结构改变,与轻瘫程度相符。在上肢肌肉:“静止”时肌反应性过高,健侧上下肢协同运动时,亦出现反
Encephalopathy can be seen in the symptoms of pneumonia, and sometimes cerebral blood circulation disorders. The authors found 12 cerebral blood circulation disorders characterized by stroke in 300 cases of lobar and focal pneumonia. Patients 42 to 18 years old, 9 cases confirmed by autopsy, 6 cases of hypertension in the body and cerebral arteriosclerosis based on the occurrence of cerebral blood circulation disorders. Acute pneumonia is a severe process of cerebral blood circulation disorder characterized by diffuse encroachment on a wide range of cortical areas, subcortical and brainstem. When acute pneumonia has a hemispheric stroke, the EEG may have a fixed, localized change in the context of diffuse changes, with most high-amplitude slow waves in the right frontal-temporal area. After treatment neurological symptoms, EEG normal. EEG changes in the deep brain tissue damage with diffuse features, was the occurrence of bilateral symmetry of high amplitude slow wave, with hemispheric asymmetry, the Department of mesencephalon structural changes due to. This shows that the degree of brain electrical activity disorders reflect the severity of clinical signs of stroke in acute pneumonia, and the lesion. Acute pulmonary insufficiency with focal brain damage in different parts of the brain blood circulation disorder, the muscle EMG changes in light: upper and lower extremity “standstill” when the electrical activity decreased or increased, with focal brain damage caused by muscle Tension reduced or increased consistent; passive and cooperative bioelectric activity increased; maximum force, the bioelectric activity decreased and changes in the curve structure, consistent with the degree of paralysis. In the upper extremity muscles: “still” when the muscle reactivity is too high, contralateral upper and lower limbs also cooperate when the movement, there are anti
