The two main types of cervical spondylosis that cause dizziness are vertebral artery cervical spondylosis and spinal cord cervical spondylosis. Vertebral artery cervical spondylosis is mainly caused by the compression of the vertebral artery for various reasons, which leads to dizziness due to insufficient blood supply to the brain, especially after turning the head and moving around. Some patients with spinal cord cervical spondylosis may also experience dizziness, mainly due to a herniated disc caused by various reasons, which leads to cerebral circulation disorders due to pressure on the spinal cord and transient increase in intracranial pressure when the cerebrospinal fluid in the dural sac cannot maintain circulation, resulting in dizziness in a rotational pattern. Other types of cervical spondylosis do not cause dizziness, but of course dizziness is not necessarily caused by cervical spondylosis, and cranial and ear lesions need to be excluded.
