Signal 1: “Drooling mouth and difficulty in speaking”. Motor nerve malfunction causes, most commonly, mouth drooling, aphasia or incoherent speech, difficulty in swallowing, weakness or immobility of one limb, falling down from holding objects, unstable walking or sudden fall, and also limb spasm or jumping. Signal 2: “Persistent headache and dizziness”. The headache that occurs during stroke is different from ordinary headache, with obvious pain, changing from intermittent headache to persistent headache; if the patient’s headache is fixed in a certain area, it may be the aura of cerebral hemorrhage or subarachnoid hemorrhage. Signal 3: “Numbness of the head and face, hemianesthesia, sudden difficulty seeing”. This is sensory dysfunction, caused by insufficient blood supply to the brain of the patient, and also a sudden feeling of vertigo, or tinnitus, hearing loss, and spontaneous pain in the limbs. Signal 4: “Mental decline”. Now mental consciousness is abnormal, personality changes, becoming withdrawn or indifferent in expression, multilingual and impatient; there is also transient loss of consciousness or mental decline. Signal 5: “Vain sweating, low fever, chest tightness and palpitations”. A small number of patients, due to cerebrovascular lesions caused by plant nerve dysfunction, will appear general weakness, sweating, low fever, palpitations or chest tightness; appear erratic, nausea and vomiting, etc. Grab the “golden emergency 2 hours” Generally speaking, the best time to save a stroke is within four or five hours; if we count the time to do the relevant examination after the patient arrives at the hospital, the best time to send the actual patient to the hospital should be controlled within 2 hours. Resuscitation time is crucial for stroke patients; brain cells are fragile and will necrotize once there is no blood supply. For stroke patients, cerebral thrombosis blocks the blood supply pathway to the brain. If the pathway is not opened before the cells die, patients may suffer from sequelae such as limb weakness, aphasia, or even death due to coma, vegetation or even death. In general, stroke “prefers” people over 40 years old, especially those with high blood pressure, diabetes, coronary heart disease and so on. In recent years, the younger stroke is more common, most of them have poor living habits, alcohol, smoking, low exercise, high-calorie diet, excessive nightlife, etc., while work stress, mental tension, emotional agitation will also increase the risk of disease. Therefore, it is important to develop good lifestyle habits. People with high risk of hypertension and diabetes, under 50 years old, can take aspirin daily for prevention.
