How to quickly identify if you have had a stroke? This is a question that needs the attention of everyone in the community as well as learning. Quickly identifying a stroke will help to get the most timely treatment in the shortest time and avoid crippling tragedies. Stroke is divided into ischemic stroke and hemorrhagic stroke. Among them, ischemic stroke includes transient ischemic attack (this is considered by neurologists as a more dangerous state than cerebral infarction because it is a precursor manifestation of cerebral infarction), cerebral infarction and venous sinus thrombosis. Hemorrhagic strokes include cerebral hemorrhage and subarachnoid hemorrhage. The symptoms of ischemic stroke are mainly neurological deficits and usually do not include severe and intense headache. In case of severe, intense and persistent headache with nausea, vomiting, altered level of consciousness (loss of consciousness or blurred consciousness, etc.) and some corresponding neurological deficits, be alert for hemorrhagic stroke. If you or someone close to you has any of these symptoms, whether they are persistent or intermittent, please go to your local hospital as soon as possible. If you are eligible for thrombolytic therapy and are lucky enough to receive thrombolytic therapy and regular antiplatelet and rehabilitation treatment within the time window (within 4.5 hours after the onset of anterior circulation infarction and within 24 hours after the onset of posterior circulation infarction), the disability and death caused by stroke can be greatly reduced.
