Numbness of the scalp is not necessarily a precursor to cerebral infarction, but may also be cervical spondylosis, emotional factors affecting, and so on. Clinically, there are relatively more diseases that can cause numbness of the scalp, and cerebral infarction is one of the reasons, which refers to a kind of blood circulation disorder in the brain, caused by ischemia, hypoxia, limited ischemic necrosis or softening of brain tissue. Before the onset of cerebral infarction, people with cerebral infarction will first experience transient motor and sensory dysfunction, numbness in different parts of the body, and impaired consciousness. In addition, people suffering from cervical spondylosis, the cervical spondylosis will lead to neurovascular compression, resulting in scalp numbness, dizziness and other symptoms. When the general population is in a state of anxiety, tension, nerve tension can also cause scalp numbness, which is a normal physiological phenomenon. If the symptoms of scalp numbness persists and has not been relieved, it is recommended to go to the hospital brain neurosurgery examination to clarify the diagnosis.
