The occurrence of this condition of dizziness and weakness in the head needs to be further analyzed in the context of the patient’s general condition. First, if the patient has nighttime sleep disorder and dizziness and weakness appear the next day, consider it to be related to sleep disorder. Second, if the patient suffers from hypertension and the blood pressure returns to normal after giving antihypertensive treatment, and the patient’s dizziness and weakness disappear, it is considered to be caused by hypertension. Third, if the patient is elderly and has obvious atherosclerosis, persistent dizziness and dullness during the day and unclearness of mind, he may be suffering from cerebral arteriosclerosis. Fourth, if the patient also has depressed mood and decreased interest, he or she may be suffering from depression. The above possibilities do not represent all the diseases of the patient, but it is still recommended that the patient go to the hospital for further detailed examination.
