Most of the long-term cerebral tinnitus is considered to be caused by cerebral atherosclerosis, mostly seen in middle-aged and elderly people, and most of the patients have hyperlipidemia, diabetes mellitus and hypertension at the same time. It may also be caused by mental disorders, such as anxiety and depression. If the patient has a vascular malformation, such as severe stenosis, the blood flowing through the narrowed vessel may hit the vessel wall and the patient may also develop cerebral tinnitus. The main reason for the occurrence of tinnitus is to apply some drugs to improve blood circulation and regulate sleep, and if necessary, to apply drugs to soften blood vessels for treatment, and to instruct the patient to rest properly.
