Many patients come to the clinic and say, “Doctor, I’m dizzy and I have insufficient blood supply to the brain.” It has been explained to him or her that the expression “insufficient blood supply to the brain” has been abolished for many years, but many patients still feel suspicious and think that the doctor does not know how to see the patient. In fact, upon careful inquiry, many patients suffer from otoliths or psychogenic dizziness. There are several causes of dizziness, such as: psychogenic dizziness, otolithiasis, Meniere’s disease, and dizziness caused by other diseases. In order for the doctor to determine the specific cause, it is recommended that you give the doctor as much detail as possible about the onset of the disease when you visit the clinic, such as: how long you have had the disease, under what circumstances the dizziness occurred, whether it is related to the change in position, how long each dizziness episode lasts, and whether it is accompanied by tinnitus, ear congestion, or headache. The doctor will be able to provide reasonable treatment only if the cause of the disease is clear.
