Stroke, also known as cerebrovascular accident. It is generally divided into two categories: hemorrhagic stroke such as cerebral hemorrhage and subarachnoid hemorrhage, and ischemic stroke such as cerebral artery thrombosis and cerebral embolism. This disease occurs in patients over 40 years old with pre-existing atherosclerosis, hypertension, cerebrovascular malformation, and heart disease. Most of them are triggered by mood swings, worries and anger, alcohol consumption and mental overstrain.
Some typical or atypical symptoms, i.e. stroke precursors, can often appear before the stroke occurs. The common ones are
