A stroke is a brain attack. The precursors of stroke may include numbness and weakness of the limbs, or there may be no precursors.
Strokes have a rapid onset and may be asymptomatic before the onset of the disease, or they may present with symptoms, such as numbness and weakness of the limbs. If recognized early and treated actively and effectively, the harm caused by stroke can be reduced.
Stroke is mainly due to ischemia, hypoxia and necrosis of brain tissues, resulting in corresponding clinical symptoms, which can be manifested as sudden crooked mouth, drooling, speech dysfunction, weakness or impaired mobility of one side of the limbs, etc., and in severe cases, there will be impaired consciousness.
Therefore, when the above abnormal symptoms occur, you should go to the hospital in time, under the guidance of the doctor for examination and treatment.
