Can cervical vertebra oppress nerve to cause cerebral blood supply insufficient

In general, cervical compression of nerves does not cause cerebral insufficiency. If the patient's cervical spine shows compression of the vertebrobasilar artery, it may show arterial insufficiency. Generally speaking, cerebral insufficiency is caused by decreased blood flow to the nerve cells in the brain. If the cervical spine compresses the nerve, it only affects the nerve conduction, but it does not produce obvious pathological changes or effects on the blood vessels. However, if the cervical spine compresses the blood vessels, the patient may show signs when turning his head. After compressing the blood vessels, it will lead to relative insufficient blood supply.
