Symptoms of cerebral stenosis can vary, with mild cerebral stenosis showing no symptoms and severe cerebral stenosis showing different symptoms depending on where it occurs.
Cerebral stenosis is commonly seen in patients with atherosclerosis. Cerebral stenosis reduces the amount of blood passing through the cerebral blood vessels, resulting in ischemia and hypoxia of brain cells. Generally speaking, if the cerebral stenosis is mild and the ischemia and hypoxia are not obvious, the body may not have any symptoms.
However, in the case of moderate to severe cerebral stenosis, depending on the location of the stenosis, the symptoms may vary. For example, the stenosis of internal carotid artery system can be manifested as weakness and numbness of one side of the limbs of the patient; if it is the stenosis of blood vessels of the brainstem and cerebellum, it can be manifested as dizziness, nausea, vomiting, and unsteady walking with ataxia and other symptoms.
Once the corresponding symptoms appear, you should go to the hospital in time for relevant examinations.
