Postural hypotension: In squatting or lying position, if you get up violently, it is likely to induce postural hypotension, resulting in ischemia and hypoxia of brain tissues, which may cause sudden fainting and blankness of the brain, and it may be accompanied by transient blackness in front of the eyes.
3. Cervical spondylosis: Commonly found in patients with cervical disc herniation, the herniated cervical discs are prone to compress local blood vessels, which may cause insufficient blood supply to the vertebral basilar arteries, which may result in sudden fainting and blankness of the brain.
4. Epileptic seizures: If there is a history of epilepsy, when epilepsy focal seizures, it may cause sudden fainting, blank brain, may also be accompanied by foaming at the mouth, mouth and eyes askew and other manifestations.
