Dizziness is a very complex disease. If no clear disease can be found after doing all neurological or complete physical examination and auxiliary examination, it is important to consider whether it is a neurological dysfunctional disease. In case of anemia, hypertension, various metabolic toxic encephalopathies, or intracranial organic diseases above the vestibular, brainstem, or vestibular nuclei, the diagnosis can usually be confirmed by blood tests or related ancillary examinations. However, if the disease is neurological dysfunctional, it is easy to be ignored by patients. Patients can be asked whether they have anxiety or depression, whether they are always tense, worried or afraid, or whether they often have symptoms such as depression, negativity, frustration, disinterest in anything, physical fatigue, weakness or insomnia. If there are these symptoms, consider the possible combination of neuroendocrine disorders, which can be considered as anxiety and depression disorders, and dizziness can be one of the manifestations of anxiety and depression disorders.
