The numbness in the back of the head may be caused by vertebral artery cervical spondylosis, cerebrovascular disease, autonomic dysfunction, etc., and the cause of the disease should be identified in time.
1. Vertebral artery-type cervical spondylosis: herniated intervertebral disc leads to vertebral artery compression, which in turn leads to vertebral artery stenosis, causing insufficient blood supply to the brain, which may lead to numbness at the back of the head, usually accompanied by dizziness, headache and other symptoms.
2. Cerebrovascular disease: cerebral infarction may lead to cerebral nerve damage due to ischemia and hypoxia, resulting in cerebral dysfunction, which may cause numbness at the back of the head, accompanied by facial obliquity, hemiparesis, speech disorders and so on.
3. Autonomic nerve dysfunction: Autonomic nerve dysfunction caused by long-term mental stress and psychological pressure may result in numbness in the back of the head, which is often accompanied by headache, dizziness, insomnia, forgetfulness, and lack of mental concentration.
This symptom alone is not enough to diagnose the disease, and may be caused by other factors, such as intracranial lesions. It is recommended that the patient consult a doctor in a timely manner to clarify the cause of the disease and provide targeted treatment.
