Stroke is a group of diseases in which the blood vessels in the human brain, for one reason or another, cause impairment of the intracranial blood supply, resulting in damage to brain tissue, and can be divided into acute and chronic according to the course of its onset. The first line of defense in stroke prevention is to control high blood pressure, which should be kept stable within a certain range. If you experience a transient cerebral ischemic attack (sign), you should immediately go to the hospital for examination and treatment. The general risk of stroke is within 2 to 4 weeks after a transient ischemic attack. Pay attention to the treatment of diabetes, heart disease and arteriosclerosis, which are the basis for the development of stroke.
