Increased cerebral arterial blood flow rate may have no obvious symptoms, or there may be symptoms such as dizziness, headache, etc., speech disorders, and limb movement disorders.
In normal people, the cerebral blood flow is regulated by the cerebral blood vessels themselves, and when the arterial blood flow rate increases due to emotional excitement and other factors, there may be no obvious clinical manifestations. However, in cases of arterial stenosis and other pathologic factors that cause an increase in blood flow rate, some clinical signs may appear.
In mild arterial stenosis, there may be no obvious symptoms due to the compensation of the opposite side of the artery; in severe stenosis, the blood flow rate will drop sharply while the blood flow rate increases, resulting in insufficient local blood supply, headache, dizziness, and other symptoms, and in severe cases, it may also lead to speech disorders, impaired movement of limbs, and other signs of cerebral infarction.
It is recommended to go to the hospital in time when the blood flow rate of cerebral arteries is found to be increased, so as to clarify the cause of the disease and intervene in time for treatment.
