Buzzing inside the head, medically known as cranial tinnitus, is a common neurological disorder whose causes are mainly anxiety disorders and chronic cerebral blood supply deficiency. Most anxiety disorders are caused by the patient’s abnormal emotions, and are related to the patient’s personality as well as the environment he or she is in and the things he or she encounters. The manifestations are often thinking about things, the brain cannot be quiet, easily losing temper, irritability and fear of noise. Chronic cerebral blood supply deficiency is related to the patient’s age, living habits and underlying diseases. It is recommended that the patient improve the relevant examination of cerebral blood vessels to clarify whether there is atherosclerosis with plaque formation. Generally, atherosclerosis is the basis of cerebrovascular ischemia, and most patients can be found to have plaque formation in the blood vessels, which affects the blood flow, resulting in long-term ischemia and hypoxia in the brain, causing chronic demyelination of nerve cells or ischemic damage, and then cranial tinnitus can easily occur.
