What causes insufficient blood supply to the brain? Well, for this situation, there could be multiple reasons.
Firstly, cervical spondylosis can cause compression of the vertebral artery, leading to insufficient blood supply to the brain.
At the same time, heart failure can also result in this condition.

In addition, diseases of the cerebral blood vessels themselves can also lead to insufficient blood supply to the brain.
So, the causes are quite complex, and specific circumstances need to be determined through examinations.
