Stroke refers to the obstruction or rupture of cerebral blood vessels resulting in impaired cerebral blood circulation and structural or functional damage to brain tissue. The clinical symptoms are complex and the clinical manifestations depend on the size and location of the brain tissue injury foci and the blood supply vessels. Stroke can be divided into two categories: ischemic stroke and hemorrhagic stroke. Both types of stroke can have the same clinical symptoms: (1) Typical symptoms: weakness and numbness of one limb, slanting of the mouth and tongue, slurred speech or incomprehension of others’ speech, etc. These symptoms are more common. (2) Atypical manifestations: dizziness can be dizzy, dizziness can be a feeling of spinning, or just a feeling of dizziness, double vision, difficulty swallowing or choking on water, or unstable walking, slanting to one side when walking, hitting the door frame, or pain in the side, or shaking of limbs and other atypical manifestations. (3) Critical manifestations: headache, confusion or even coma, or the respiratory and circulatory center may be involved to endanger the patient’s life, which is due to the large area of brain tissue damage or damage to the respiratory and circulatory center. If the patient has slurred speech, numbness and weakness of the limbs or other symptoms mentioned above when he/she is not active or wakes up, ischemic stroke is more likely, then the patient should be kept in a quiet and flat position, avoid emotional agitation and seek medical attention at the hospital in time; if the patient suddenly develops after emotional agitation or exertion and has severe headache, nausea, vomiting or other symptoms mentioned above, then hemorrhagic stroke is more likely, call 120, avoid moving the patient before the arrival of the paramedics, loosen the collar, tilt the head to the side, avoid blocking the airway with vomit and oral secretions, ensure a smooth airway, and also pay attention to avoid bumps when transporting the patient. In summary, stroke can present with a variety of symptoms, but the etiology varies. If you suspect a stroke, you should seek prompt medical attention and professional diagnosis and treatment.
