Domestic census reports the incidence of this disease at 3.8% to 17%. As the life expectancy increases, the problem of cervical spondylosis is becoming more prominent. There is a survey on the incidence of cervical spondylosis: about 25% by the age of 50, about 50% by the age of 60, and about 95% or more by the age of 70. Why are the majority of headaches and dizziness in the middle-aged and elderly related to cervical spondylosis? Because as we age, the human intervertebral disc (i.e., the disc-like non-bony tissue between the two vertebrae, which plays the role of cushion) gradually degenerates, decreases in elasticity, and expands around, or even protrudes, resulting in narrowing of the gap between the upper and lower vertebrae, osteophytes at the edge of the vertebral body and its small articular protrusions (including the hook vertebral joint), and instability between the vertebrae. These changes are most likely to occur in the 3rd to 5th cervical vertebrae, which have a wide range of motion, and can cause involvement of the nerve roots (whose branches are located in the ipsilateral shoulder and upper extremity) and vertebral arteries (which mainly supply blood to the posterior brain, including the brainstem). This can cause complex clinical manifestations such as headache, dizziness and/or vertigo, nausea, vomiting, eye swelling, blurred vision, ear “closed air”, tinnitus, etc., cervical stiffness, neck and shoulder pain, and numbness in the fingers (mostly in the little finger, ring finger, and small fissure muscle); some patients may also develop cardiovascular symptoms such as vague pain in the precordial region, cardiac arrhythmia, and tachycardia. Some patients may also experience cardiovascular symptoms such as anterior cardiac discomfort, arrhythmia, tachycardia, etc. As the symptoms of cervical spondylosis are related to the type of occurrence, the most common type is the neurogenic type, followed by the vertebral artery type and sympathetic nerve type, but in fact, the clinical symptoms of most cervical spondylosis attacks often involve two or three types (the so-called mixed type), such as headache, dizziness and vertigo, nausea, vomiting, numbness of fingers and cardiovascular symptoms. If cervical spinal stenosis causes spinal stenosis, compression of the spinal cord may also cause instability in walking and may lead to paralysis. Headache, dizziness and/or vertigo are the most common complaints of cervical spondylosis.
