Insufficient blood supply to the brain caused by cervical spondylosis is mainly treated by improving blood circulation. Commonly used clinical drugs include Shuxinin, Vibram, Chuanxiongzin and Pethidine, etc. Ginkgo biloba drops and Cipro can also be taken orally. In severe cases, cervical spine traction or surgery can be given. Insufficient blood supply to the brain caused by cervical spondylosis is mainly due to the compression of the transverse foramen by a herniated cervical disc, which causes impaired blood supply to the vertebral artery, and can also be caused by the straightening of the cervical curvature of the vertebral artery. Patients mainly show signs and symptoms of cerebellar ischemia, such as dizziness, nausea, vomiting, ataxia, dysarthria, balance disorder, diplopia, nystagmus, dysphagia, choking on water, etc. Ischemic foci can appear on cranial magnetic examination.
