The following reasons are considered: 1. Physiological factors, such as poor sleep, emotional anxiety and stress, may cause the feeling of dizziness, and there may be transient brain blankness. 2. Pathological conditions, patients feel dizzy mainly due to insufficient blood supply to the brain and cerebral atherosclerosis, such as cerebral vascular stenosis, slow blood flow to the brain, or due to hypotension, hypertension, anemia, etc. For example, because of cerebral vascular stenosis, slow cerebral blood flow, or because of hypotension, hypertension, anemia, etc., all can lead to the symptoms of head clouding. Chronic intracranial tumors and intracranial occupying lesions can also cause patients to feel cephalic, but their symptoms will gradually progress and worsen. If the patient is in improper posture, with stiffness and pain in the neck, it should be considered to be related to the cervical spine. Because of osteophytes or herniated discs in the cervical spine, the patient will experience dizziness, lightheadedness, and dullness when the vertebral artery is compressed, causing insufficient blood supply to the brain.
