[Research progress on the screening questionnaire related to benign paroxysmal positional vertigo]

Benign paroxysmal positional vertigo（BPPV） is the most common peripheral vestibular disease in clinical practice, which can easily lead to missed diagnosis and misdiagnosis. Many guidelines have emphasized that detailed medical history and Dix-Hallpike test are sufficient to complete the diagnosis of BPPV. However, when the patient is unable or refused to undergo the displacement test due to obesity, physical weakness, cervical or lumbar dysfunction, fear of dizziness, and the displacement test does not induce nystagmus or weak nystagmus, the detailed medical history provides a supplementary basis for the diagnosis of BPPV, and compulsive posture therapy and drug treatment can be carried out accordingly. In order to standardize consultations, shorten the time for patients to visit, and help clinicians make more accurate diagnoses, many scholars at home and abroad have designed relevant screening questionnaires based on the history of BPPV, which has achieved good results.This article is summarized as follows, in order to provide ideas and references for clinical inquiry.
