”Dizziness” (medically classified as dizziness and vertigo) is a very common clinical problem and one of the most common reasons for patients to seek medical treatment. However, due to insufficient general education, low level of general practitioners and narrow knowledge of specialists in China, a large number of patients fail to receive timely and correct diagnosis and treatment. Many patients were arbitrarily diagnosed as “cerebral blood supply deficiency” or “cervical spondylosis”, and were treated with a lot of “blood activation” and even surgery, but the results were not satisfactory. In fact, dizziness caused by cervical spondylosis and cerebral insufficiency is not common in clinical practice. One of the most common mistakes that many patients make is to try to figure out whether the cause of their dizziness is “cerebral insufficiency” or “cervical spondylosis”, and even to see themselves and request various tests. This is because most adults, especially the elderly, have “osteophytes”, “multiple cavernous infarcts” or “insufficient blood supply to the brain”. These changes are very common in the elderly and are associated with physiological aging or other diseases (such as hypertension, diabetes, etc.), but are not the cause of dizziness or vertigo. Therefore, patients should not blindly request or expect tests, and should not read the “osteophytes”, “multiple cavernous infarcts” or “insufficient blood supply” on the test report for clinicians’ reference only, and then make their own diagnosis. Do not make your own diagnosis by reading “osteophytes”, “multiple cavernous infarcts” or “insufficient blood supply” on the examination report, and then blindly seek treatment. The most common clinical causes of dizziness or vertigo are peripheral vestibular disorders, medical disorders, and psychiatric disorders. Most of them are not caused by cervical spondylosis or insufficient blood supply to the basilar artery. Therefore, patients with dizziness should first go to neurology, cardiovascular medicine, medical otolaryngology, etc., instead of taking the initiative to go to orthopedics or rehabilitation to treat “cervical spondylosis” to avoid delaying the diagnosis and treatment.
