Numbness in the back of the head may be an early manifestation of cerebral infarction (cerebral thrombosis), or it may be caused by physiological factors, such as cold, mental stress, etc., and it may also be related to cervical spondylosis and so on.
1. Physiological factors:
(1) Cold: in the state of cold temperature of the external environment, the symptom of numbness in the back of the brain can occur due to low temperature stimulation.
(2) Emotional factors: emotional tension or shock may cause sympathetic excitation, which may lead to numbness in the back of the head.
2. Cerebral infarction: If the numbness in the back of the head persists, accompanied by slurred speech, limb movement and other symptoms, it cannot be excluded that cerebral infarction develops, and it needs to be diagnosed by cranial CT or magnetic resonance imaging (MRI).
3. Cervical spondylosis: when suffering from cervical spondylosis, due to the compression of cervical nerve roots can be radiated to the posterior occipital region, and the patient will feel numbness in the back of the head. It can be diagnosed by cervical radiographs or MRI.
It is recommended that patients who experience numbness in the back of the head that is not relieved for a long time should consult a doctor as soon as possible to clarify the cause and under the guidance of the doctor.
