The early symptoms of cerebrovascular disease may include dizziness and headache depending on the size of the lesion and the degree of vascular damage, followed by abnormal changes in intelligence or consciousness and focal symptoms. The early symptoms of cerebrovascular disease are associated with abnormal brain cell function due to cerebral ischemia and cerebral vascular spasm. If cerebrovascular disease progresses further, it may show more severe symptoms such as reflexive increase in blood pressure, headache and vomiting, abnormal sensation in the extremities, and immobility. Other patients may experience choking and coughing, suggesting paralysis of the nerves in the throat; more severe cases of cerebral hemorrhage may also show respiratory and circulatory failure and fecal incontinence. Patients with transient cerebral ischemic attack may exhibit transient hemiparesis, numbness of limbs, or even sudden fall, but they will recover on their own within a short period of time. Patients with large cerebral infarction can fall into coma, seizures, and further development of elevated cranial pressure can lead to respiratory failure and circulatory failure at an early stage. If a patient shows early symptoms of cerebrovascular disease, he or she should pay high attention and seek medical attention as soon as possible.
