Hand numbness is a relatively common phenomenon, partly due to nerve compression in the arm, such as prolonged lifting of heavy objects or prolonged arm to maintain a posture, can cause hand numbness. However, in general, if the hand numbness in older people is caused by cerebrovascular disease or stroke, patients with cerebrovascular disease may experience numbness in one side of the hand and numbness in one lower extremity, which may be accompanied by symptoms of cerebrovascular disease, such as dizziness, headache, dumbness or aphasia. Numbness in older hands can also be seen in cervical spondylosis, which is one of the most common diseases in middle-aged and elderly people. As we age, cervical disc degeneration leads to pressure on the surrounding dural sac and nerve roots, which can lead to numbness in the hands. Numbness in the hand in older people can also be seen as a result of nerve entrapment in the upper extremities, for example, patients can experience numbness and pain in the thumb, index finger, and middle finger, and usually wake up with numbness at night, and it is recommended that patients can undergo further examination.
