[Review of persistent postural-perceptual dizziness and experience of diagnosis and treatment].

The concept and diagnostic standard of persistent postural-perceptual dizziness（PPPD） improve the ability of clinical workers to recognize these diseases to some extent. However, the diagnosis of PPPD mainly depends on the identification of postural symptoms and the elimination of structural vestibular diseases, so the subjectivity is relatively strong. Moreover, the lack of objective criteria and a slight carelessness will lead to generalized diagnosis or omission diagnosis and misdiagnosis. At present, there is a lack of domestic large sample epidemiological investigation and other related studies, therefore it is a problem for diagnosing generalization of persistent posture perception dizziness and needed to be alert and corrected. Only those items meeting the criteria of the diagnostic standards can be carried out for diagnosis. The treatment needs to ensure sufficient dose and full therapy course. Generally, the medication should not be less than half a year.
