Limitations of clinical manifestations of cerebral infarction

Cerebral infarction seen more than middle-aged people, the majority have high blood pressure, diabetes, heart disease or high blood lipid history, and some have already TIAs or stroke. Acute onset usually in the development of peak within a few hours. Xingzhuan part of patients in the early morning when found that abnormal. Side can be sick headache, with little drama headache, vomiting onset. Mainly in the following four categories. (A) main artery atherosclerosis in the artery wall infarction atherosclerosis on the basis of the development of thrombosis, or emboli, cause artery disease or hemisphere of the brain cortex, the cerebellum, the brain stem the loss of local functions. Specific symptoms, see above. Can have the same arterial system TIAs history. A small number of patients in the 24 hours after the onset the continued deterioration of a ladder or increase may be due to thrombosis in a loss of expansion or new emboli. (B) cardiac infarction suppository to see more young adults are sudden onset, can increase the ladder. Often have other brain artery TIAs, history of stroke or systemic embolism history. There the cause of cardiac embolism. (C) lacunar infarction or small arterial occlusive stroke development relatively slow, and some can be as long as 36-hour period and to gradually increase the peak. Infarction small in size, according to a specific location of the focal symptoms. (1) simple movement of stroke: the side, arm, leg, foot, toe paralysis, internal capsule hind legs or bridge, in the small ventral brain infarction. (2) pure feeling of stroke: the opposite feeling very good, is seen at the lateral hypothalamus abdominal lacunar. (3) ataxia of unilateral Qingtan: contralateral arm, the hand with a total economic obstacles Qingtan legs, ventral view of the bridge cerebral infarction. (4) dysarthria - clumsy hand: Speech unclear opposite hand and the activities of obstacles to bridge the ventral brain or internal capsule of the knee infarction. (5) with the unilateral expression aphasia Qingtan: internal capsule knee and forelimb infarction involving radiation near the crown white matter. (D) Other causes of cerebral infarction non-atherosclerotic vascular diseases, blood diseases, blood coagulation, and other rare causes abnormal due to ischemic stroke.
