If tinnitus or cerebral tinnitus occurs in young people, especially in students, most of them are caused by mental factors such as tension and stress, which are functional diseases. In some cases, the head and neck muscles spasm and cannot relax, compressing the blood vessels in the neck, resulting in insufficient blood supply to the brain, or the patient has poor physical condition and low blood pressure, resulting in poor blood circulation, affecting the blood supply to the brain and causing symptoms such as tinnitus and dizziness. If it occurs in older patients or patients with hypertension, it is mostly caused by insufficient blood supply to the brain. The patient mainly shows brain tinnitus, dizziness and memory loss, and when combined with age, it is considered that there is a deficiency in blood supply to the brain and reduced brain function activity, which can trigger the above symptoms when there is insufficient sleep, excessive brain use and exertion. It is necessary to check the risk factors for cerebral atherosclerosis, such as blood pressure, blood glucose, blood lipids and blood rheology, and also to check transcranial Doppler to understand the cerebrovascular condition. You should monitor your blood pressure regularly, take care of your rest, keep a good sleep, and combine work and rest. In addition, it is also necessary to pay attention to ear diseases, and brainstem auditory evoked potential examination can help diagnose. There are many causes, mainly the following: brain diseases such as brain tumor, inflammation, degeneration, brain atrophy, stroke, arteriosclerosis and lack of blood supply to the brain; systemic diseases such as hypertension, hypotension, anemia, kidney disease, toxemia, leukemia, hyperthyroidism, diabetes, hyperlipidemia, etc.; ear diseases: tinnitus is often present, but it is a ringing in the ear rather than in the brain, and ear examination can mostly detect the lesion. In addition to tinnitus, these patients may also have poor sleep, emotional instability, lack of concentration, lack of physical strength, panic, shortness of breath, blankness in the brain, somatic pain, dizziness, headache and many other subjective symptoms, but objective examination often does not reveal organic lesions. In the past, the diagnosis was “neurosis”, “neurasthenia”, “vegetative dysfunction”, etc. Now, after clinical psychological assessment, most patients are suffering from anxiety, depression or obsessive-compulsive disorder. Other causes, such as the use of certain drugs, can also cause tinnitus.
