The sudden appearance of something invisible in one eye will recover in a few minutes or seconds, which is an early warning signal of cerebrovascular disease. Sudden choking, dysphagia, fatigue, lethargy, tinnitus and unsteady walking may also be precursors of cerebrovascular diseases. We know that for a normal healthy person, dizziness usually does not occur. Some patients with cardiovascular diseases may have similar symptoms, such as hypertension and hyperlipidemia, which will lead to dizziness. But if it is cardiovascular disease, such as hypertension and hyperlipidemia, it can be improved after people take medicine or rest.
If people find that their heads are unusually dizzy and often accompanied by nausea, they can't get rid of it after taking medicine or resting. At this point, we should pay attention to the possibility of our own cerebrovascular problems. Cerebral thrombosis is the most common condition. The reason for this is that cerebral thrombosis will make the blood circulation in the brain poor, leading to hypoxia in the brain and dizziness.
When a person's cerebrovascular thrombosis occurs, the dominant ability of the human brain will be weakened due to lack of oxygen, and the activities of human limbs are basically controlled by the human brain. Therefore, before cerebral thrombosis, people may often walk unsteadily. Usually yawning only happens when people are sleepy or tired. This is a normal physiological phenomenon. However, if people don't have the above situation, they always yawn repeatedly. At this time, it may also be a sign that brain cells have no vitality due to lack of oxygen, which should attract people's attention.
