Cervical spondylosis can cause a stroke, is it appalling? There are many people who are uncomfortable with their cervical spine, especially those who often work at a desk. 8 or 9 out of 10 people have a bad cervical spine and can tolerate neck pain, but stroke is a direct life-threatening disease. Cervical spondylosis is a clinical condition caused by degenerative changes in the intervertebral discs of the cervical spine, while stroke (also known as stroke) refers to acute cerebrovascular disease, such as transient ischemic attack, cerebral infarction, cerebral hemorrhage and other very serious diseases. These two diseases, one in orthopedics and one in neurology, may seem far apart, but in fact they are closely related. Stroke, hemiplegia, hypertension, cerebral hemorrhage and other serious diseases often have major problems in the upper cervical spine. Several studies in the medical community have also found a link between cervical spondylosis and stroke. From the anatomical point of view, for example, in patients with vertebral artery type cervical spondylosis, the vertebral artery enters the skull via the transverse foramen of the cervical spine from the foramen magnum of the occipital bone and merges around the lower edge of the pontine brain to become the basilar artery, which supplies blood to the head. The direct compression of the vertebral artery or the stimulation of the sympathetic nerve around the vertebral artery due to many factors causes the lesion of the vertebral artery, resulting in insufficient blood supply to the vertebrobasilar artery, which can easily lead to stroke. Misalignment of the cervical spine, which involves changes in the pressure of the arterial wall, causes poor blood supply to the brain. When ageing or bad posture of cervical spine use, strain and degeneration of cervical muscles and ligaments, weakening of the strength and function of fixed joints, destabilization, swing and misalignment of the cervical joints when lowering or tilting the head, will certainly stimulate the vertebral artery that travels in the transverse foramen of the cervical spine, causing spasm, contraction or distortion, and further forming insufficient blood supply to the brain. The increased degree of arteriosclerosis in the elderly, if accompanied by cervical spondylosis, will make the cerebral blood supply even more inadequate, slowing down the cerebral blood flow and making it easier to form thrombosis and induce a stroke. Therefore, the elderly should pay more attention to the prevention and treatment of cervical spondylosis. Of course, for people of any age, the cervical spine is very important.
