Cerebral hypoperfusion is a deficiency of blood supply to the cerebral artery system due to various reasons, either transient or chronic, with different symptoms. Transient cerebral artery insufficiency is a transient ischemic attack, and its symptoms appear briefly, mostly in a few seconds to a few minutes, usually not more than an hour. The latter may cause transient vertigo, unstable walking, difficulty in swallowing, slurred speech, hoarseness, hearing impairment, and other symptoms such as visual field loss, hemiparesis, and unilateral sensory impairment. Chronic cerebral insufficiency of blood supply is generally due to cerebral vascular sclerosis or heart, blood and other reasons, causing long-term blood flow to the brain, long-term ischemia and hypoxia of brain tissue, and its symptoms are generally non-specific, mostly manifested as dizziness, headache, dizziness, accompanied by irritability, irritability, forgetfulness, lack of concentration and other symptoms. In conclusion, the symptoms of cerebral hypoperfusion are related to the site of cerebral ischemia, and timely treatment is beneficial to the prognosis of the disease, so it is recommended that patients should go to the neurology department of the hospital as soon as they are found to have symptoms of cerebral hypoperfusion.
