Cerebral blood supply deficiency refers to brain dysfunction caused by insufficient blood supply to a certain part of the human brain.
Etiology: The etiology of cerebral blood supply insufficiency is related to cerebral arteriosclerosis.
The main reasons are: (1) partial arterial stenosis or vasospasm, which leads to insufficient blood supply in the brain region; (2) Hemodynamic disorder, when blood pressure drops and cardiac output decreases, blood supply to brain tissue is insufficient; (3) There may also be increased blood viscosity, slow blood and blood composition changes caused by some reasons, resulting in insufficient blood supply; (4) microthrombosis, that is, microthrombosis refers to the detachment of atherosclerotic plates and the formation of microemboli in the blood stream, which will block blood vessels as the blood flows to arterioles, resulting in insufficient blood supply to the local brain.
Clinical manifestations: language disorder; Neurological disorder; Facial paralysis, hemiplegia.
Treatment principle: reduce blood viscosity and maintain the normal function of repairing blood vessels.
==========================
In life, many people, especially middle-aged and elderly people, often have symptoms of dizziness and headache, as well as upset, tinnitus, impatience and irritability, insomnia and dreaminess, memory loss, inattention, forgetfulness (for example, what happened recently can't be remembered), etc. These are the results of chronic cerebral blood supply deficiency.
Chronic cerebral ischemia was first proposed by Japanese doctors in 1990, which refers to a series of diseases with brain dysfunction as clinical manifestations caused by chronic and extensive cerebral ischemia caused by various reasons. The incidence of chronic cerebral ischemia is high. According to statistics, 2/3 middle-aged and elderly people suffer from chronic cerebral blood supply deficiency, which is a frequently-occurring disease of middle-aged and elderly people. After a lot of research, medical scientists at home and abroad also found that in the early stage of Alzheimer's disease and cerebral infarction, chronic cerebral blood supply deficiency existed for a long time. Chronic cerebral blood supply insufficiency may cause "Alzheimer's disease" and "cerebral infarction" if it is not treated in time. Therefore, chronic cerebral blood supply deficiency is called the "invisible killer" that threatens the health of middle-aged and elderly people!
Why are middle-aged and elderly people prone to chronic cerebral blood supply deficiency? As we all know, the brain is an important organ of the human body and consumes a lot of oxygen. The weight of the brain only accounts for about 2% of the body weight, but the oxygen consumption accounts for 20% of the whole body aerobic. The oxygen needed by the brain is supplied by blood, so the brain must have enough blood to function normally. The standard of measuring cerebral blood supply is cerebral blood flow. Once the cerebral blood flow decreases, the oxygen supply and energy supply of brain cells will also decrease. As long as the brain tissue ischemia exceeds 10 second, the function of the brain will change. If the blood flow in a certain part of the brain is completely blocked in a short time, there will be local brain tissue necrosis, which is cerebral infarction; If the blood supply to the brain is not completely blocked but gradually reduced, this is chronic cerebral blood supply insufficiency. With the increase of age, the blood supply to the brain will gradually decrease. The cerebral blood flow in childhood is about 100 ml (100 ml100 g brain tissue minute), and in adulthood it is 50 ml (50 ml/100 g brain tissue minute), while that in the elderly is only 35 ml (35 ml//kloc-0 g brain tissue minute). In addition, the tolerance of brain tissue to ischemia in middle-aged and elderly people is relatively low, and the automatic regulation function of cerebral blood vessels is gradually declining. Therefore, as long as the blood supply changes slightly, it will obviously affect the cerebral blood flow, which will lead to the occurrence of chronic cerebral blood supply insufficiency.
Chronic cerebral blood supply deficiency is reversible in the early stage, and correct treatment will often achieve good results; If you endure procrastination without timely treatment, it will often lead to serious consequences.
