In general, atherosclerosis exists in middle-aged and elderly people, which leads to the loss of elasticity of the vessel wall and affects the blood flow rate, which can lead to ischemic and hemorrhagic cerebrovascular diseases. For hand numbness caused by cerebrovascular disease, it can also be accompanied by other symptoms of neurological deficits, such as headache, dizziness, aphasia and dumb speech, etc. The diagnosis can be confirmed by CT or nuclear magnetic examination of the head, and it is recommended to actively treat cerebrovascular disease and start secondary prevention of cerebrovascular disease. Secondly, hand numbness in the middle-aged and elderly can also be seen in cervical spondylosis, which can occur when the cervical spine has osteoporosis or degeneration with age, resulting in compression of the dural sac and nerve roots. For hand numbness caused by cervical spondylosis, it is usually more obvious at night and reduced in the morning after activity, so you can check the cervical spine nuclear magnetic examination to confirm the diagnosis and give the patient traction and other treatments, and if necessary, you can also do acupuncture treatment.
