Part One: The Brain’s “Blood Supply Channel” Is Being Pinched by the Cervical Spine

1. The vertebral artery – the lifeline of the posterior cerebral circulation

To understand the relationship between the cervical spine and brain blood supply, you first need to know an important blood vessel – the vertebral artery. The vertebral artery arises from the subclavian artery, travels upward through the bony “tunnels” formed by the transverse foramina on both sides of the cervical vertebrae, and eventually joins the basilar artery. It supplies blood to key regions including the cerebellum, brainstem, and occipital visual cortex. When the cervical spine develops structural abnormalities due to degenerative changes, bone spurs, disc herniation, or other reasons, the vertebral artery can be compressed, twisted, or even occluded – leading to insufficient posterior circulation blood flow.

2. Typical symptoms of posterior circulation ischemia

When vertebral artery blood flow decreases, the brain regions most sensitive to ischemia – the cerebellum (responsible for balance), brainstem (controls heartbeat and breathing), and occipital lobe (processes vision) – are affected first. As a result, you may start feeling dizzy and unsteady; your vision may black out when turning your head; you may see blurry or double images; you might even experience brief episodes of confusion or memory decline. These symptoms closely resemble common cerebrovascular disorders, but the cause is completely different – the problem is not in the brain, but in the cervical spine.

 

Part Two: Identifying Vertebral Artery Cervical Spondylosis and Its Risks

1. The close relationship between symptoms and neck movement

Cervical spine lesions causing insufficient brain blood supply are medically termed “vertebral artery type cervical spondylosis.” An important characteristic is that symptoms are closely related to neck movement – they worsen when bending the head down, turning the head, or looking up, and improve with rest in a stationary position. You should be highly alert if you frequently experience the following:

• Vertigo is one of the most typical manifestations. This vertigo is often related to positional changes – when getting up, turning over in bed, or looking up at something high, you suddenly feel as if the surroundings are spinning, sometimes accompanied by nausea and vomiting.

• Drop attacks are a sign that requires serious attention. While walking or standing, you suddenly feel your legs give way and fall, but you remain conscious and can stand up again within seconds. This usually indicates a transient episode of cerebral ischemia.

• Visual disturbances are also common – sudden blurry vision, blackouts, or double vision, often transient.

• Headaches and insomnia – throbbing pain at the back of the head, memory decline, and persistent difficulty falling asleep.

2. The combined risk of cervical degeneration and cerebral atherosclerosis

What deserves even more attention is that cervical spondylosis is not simply a problem of insufficient blood supply; it may also create a risk combination with cerebral atherosclerosis. Chronic cerebral hypoperfusion caused by cervical degeneration can damage the vascular endothelium, making it easier for lipids to deposit on vessel walls. At the same time, sustained sympathetic excitation increases vessel wall pressure and accelerates vascular fibrosis. Therefore, middle‑aged and older adults with cervical spondylosis should pay greater attention to comprehensive management of cerebrovascular health.

 

Part Three: Qiteng Therapy – Clearing Obstacles in the Brain’s Blood Supply Channel

1. Three mechanisms by which Qiteng Therapy improves vertebral artery blood supply

When these troubling symptoms persist and neurology examinations find no clear cause, it may be time to look at your cervical spine. Qiteng Therapy, as an external TCM technique focused on opening the neck passages, can improve vertebral artery blood supply on multiple levels:

• Relieves mechanical compression: Deep herbal heat penetration reaches the deep soft tissues, alleviates cervical muscle and fascia spasm, and reduces compression on the vertebral artery.

• Improves the circulatory environment: The warming effect promotes cervical blood circulation, accelerates removal of metabolic waste, and reduces blood viscosity.

• Restores neural regulation: Releases adhesions around the sympathetic nerves, removing the abnormal excitatory effect that causes spasmodic constriction of the vertebral artery.

2. The complete pathway from “opening the neck” to “nourishing the brain”

When qi and blood flow freely, the brain is nourished. As the “stagnant waste” in the neck is gradually broken down and expelled, the cervical channels reopen, the vertebral artery is no longer compressed, and blood supply to the brain improves accordingly. Symptoms caused by insufficient blood supply – dizziness, blurred vision, memory loss – will naturally ease as the blood supply channel is restored.

3. Special note: first rule out acute or severe cerebrovascular disease

If you have long been troubled by unexplained dizziness, blurred vision, or memory decline, and routine tests have not identified the problem, consider shifting your focus away from the brain itself and looking down at your cervical spine. After excluding cerebrovascular pathology, systematic therapy targeting the cervical spine can often yield unexpected improvements. However, the prerequisite for treatment is always to first undergo a standard evaluation at a regular hospital’s neurology or emergency department to rule out acute serious conditions such as cerebral hemorrhage, cerebral infarction, or intracranial space‑occupying lesions.

The brain’s distress signal does not always come from the brain itself. Sometimes, the answer lies hidden in your neck.
