In patients with dizziness, it is possible to determine whether the dizziness is related to cervical spondylosis by determining whether the patient has cervical spondylosis, by ruling out causes other than cervical spondylosis, and by trying treatments. The specific ways of judgment are as follows 1. Determine whether the patient has cervical spondylosis: At this time, it is necessary to combine the patient’s symptoms, medical history and physical examination to make a preliminary diagnosis of the patient. After that, it is also necessary to combine the cervical spine X-ray, CT or MRI and other auxiliary examinations to confirm whether the patient has cervical spondylosis, and whether vertigo will occur. 2. Rule out other causes: After confirming the presence of cervical spondylosis, it is necessary to clarify whether the patient has other causes of vertigo, such as hypertension, cerebral infarction, etc. 3. Pilot treatment: If it is clear that cervical spondylosis is the main cause of the disease after the preliminary examination, then the patient can try the relevant treatments for the disease first. For example, it is necessary to keep the patient in bed, traction, and the application of some drugs to improve the blood circulation of the brain, such as hemosiderosis. If the treatment is effective, the condition can be finally clarified. The use of these medications should be done under the guidance of a doctor, and should not be self-administered. It is recommended that patients with vertigo should go to an orthopedic clinic in time to clarify their condition.
