There are many diseases that can cause this symptom, such as craniocerebral injury, encephalitis, arteriosclerosis, and poisoning, etc. It is recommended that the patient go to the Neurology Department of the hospital for further consultation, to investigate the cause of the disease, and then treat the symptoms.
