What symptom does ischemic headache have?
summary
Cerebral ischemia can be seen in the pathological process of a variety of neurosurgical diseases, such as cerebrovascular disease, brain tumor, etc., and also in the systemic pathological process of cardiac arrest, shock, etc. Cerebral ischemia can be manifested in different forms, including focal and diffuse cerebral ischemia, permanent and temporary cerebral ischemia. However, no matter how it appears, the pathophysiological mechanism and biochemical changes of cerebral ischemia are basically similar, and are related to the degree and duration of cerebral ischemia. What symptom does ischemic headache have? Let's talk about it
What symptom does ischemic headache have?
(1) TIA of internal carotid artery system: sudden transient hemiplegia, hemiparesthesia, unilateral facial and hand involvement are common, and monocular transient blindness or amaurosis may also occur. The patients with primary hemisphere involvement had speech dysfunction, transient dyslexia, agraphia and aphasia.
(2) Vertebrobasilar artery system TIA: the symptoms are more complex than internal carotid artery system. Vertigo and hemianopia were the most common symptoms. In addition, facial paralysis, tinnitus and dysphagia can also occur. Headache, diplopia and ataxia can also be the chief complaints of patients. Perioral sensory disturbance is the manifestation of brainstem involvement. Bilateral temporal internal ischemia can cause sudden memory impairment, which is more common in the elderly. Anterograde amnesia is more common than retrograde amnesia, which can last for several hours. In the short term after TIA and rind, the incidence of cerebral infarction is high. 9% - 20% of TIA and rind patients eventually develop into cerebral infarction. Among them, 20% occurred within one month and 50% within one year.
The former refers to the condition is stable without progress, lasting 24-72 hours, also known as complete stroke. 11% - 13% of the patients had occult onset, no clinical symptoms and signs, only ischemic focus was found on imaging.
matters needing attention
Active prevention and treatment of atherosclerotic plaque, prevent embolus fall off, pay attention to the prevention and treatment of etiology.
