Due to insufficient blood supply to the brain affecting the analysis of the brain area, sensory and sensory fibers, often manifested as facial anesthesia, tongue anesthesia, labialis and limb numbness or foreign body sensation; some into the visual unclear, or even Sudden temporary blindness; many people have a sudden dizziness; some spontaneous pain; there are sudden onset of tinnitus, hearing loss and so on.
Motor nerve dysfunction
This type of warning sign is the most common. Due to lack of blood supply to the brain in charge of motor function of human nerve failure, common manifestations such as sudden mouth crooked, drooling, speaking difficulties, unclear articulation, aphasia or language is not satisfactory, dysphagia, limb weakness or movement is not working, Drops, walking instability or sudden falls, and some appear to convulsions or beating.

(1) The main reason
Cervical atlantoaxial joint and cervical 5 neck 6 joints dislocation, stimulate the vertebral artery causing arterial stenosis or vasospasm, decreased blood flow through the resulting supply of brain area insufficiency;
(2) hemodynamic disorders
When the blood pressure is reduced, the amount of heart stroke is reduced when the brain tissue insufficiency;
(3) increased blood viscosity
Some causes of increased blood viscosity, slow blood and blood composition changes can occur and lack of blood supply;
Micro-thrombosis that arterial atherosclerosis plate off, the formation of micro-emboli in the bloodstream, with the blood flow to the arteriole and occlusion of blood vessels, there will be partial cerebral insufficiency.
1, neck type
Occipital and neck pain, cervical activity is limited, stiff neck, a corresponding tender point.
2, nerve root type
Cervical spine with upper extremity radiating pain, aggravate neck posterior extension, pressure nerve root skin segment distribution decreased, tendon reflex, muscle atrophy, limited mobility. X-ray will show vertebral hyperplasia, hook joint hyperplasia obvious, intervertebral space narrowing, intervertebral foramen smaller.
3, spinal cord type
Early lower extremities tightening, walking instability, paralysis of the lower extremity or limbs in the late stage, incontinence or urinary retention, the following sensory disturbances in the compression spinal cord segments, increased muscle tone, hyperreflexia, vertebral body bundle signs positive, and X-ray There will be narrow intervertebral space, more serious posterior vertebral hyperplasia and protruding into the spinal canal.
4, vertebral artery type
Headache, dizziness, tinnitus, deafness, blurred vision, catastrophic cataclysms, and aggravating symptoms of cervical scoliosis. CT may show asymmetric size of transverse cranial foramen, relatively narrow side, narrowing of transverse process, Spinal hyperplasia.
5, sympathetic type
Face weakness, blurred vision, headache, dizziness, occipital neck pain, CT showed color vertebral hyperplasia, foraminal stenosis, cervical dislocation in varying degrees, vertebral artery compression phenomenon.
