What's wrong with the brain?

The brain is not sober mainly manifested as a sense of dizziness, concentration, concentration decline, and even some people can show memory decline, slow response. First of all, we need to consider whether there is fatigue, irregular diet, too frequent smoking and drinking, anxiety, insomnia. After excluding these reasons, we need to consider the pathological reasons. General dizziness is the performance of brain hypoxia, can be divided into brain cells relative hypoxia and absolute hypoxia. Relative hypoxia, such as thin oxygen at high altitude, and anemia for a long time caused by insufficient oxygen in the blood, causing hypoxia in brain cells and brain drowsiness. Absolute hypoxia is more common in cerebral vascular blockage causing cerebral blood supply deficiency or cerebral infarction, causing severe hypoxia in brain cells, which can cause serious sequelae, such as cognitive decline, hemiplegia, aphasia, etc., requiring timely treatment.
