Vertigo six questions - self-diagnosis of benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo (BPPV), also known as otolithiasis, is the most common vertigo disorder

Due to some reasons, the normally attached otoliths in the utricle and balloon fall off, and enter the semicircular canals with the flow of lymph fluid.

Middle-aged and elderly people aged 50-60 are the peak incidence group

BPPV is divided into posterior semicircular casts, horizontal semicircular casts and superior semicircular casts, of which posterior semicircular casts account for 60% to 90%, followed by horizontal semicircular casts, and superior semicircular casts are rare

BPPV can be spontaneously relieved without treatment, the average 7 d remission of horizontal semicircular canal BPPV, and the average 17 d remission of posterior semicircular canal BPPV

Manipulative reduction of otoliths is an effective method for the treatment of BPPV

Medications are used to relieve severe nausea and vomiting

In recent years, clinicians have made great progress in their understanding of BPPV

The use of scales or questionnaires can make the diagnosis and treatment of BPPV simple and easy.

The first three questions were used to exclude patients with dizziness/vertigo due to disorders other than BPPV

Question 4 is used to distinguish BPPV between the horizontal and posterior semicircular canals

Question 5 is used to determine which side is affected

If the diagnosis of horizontal semicircular canal BPPV is determined according to question 4, the answers to questions 5 and 6 are used to determine the affected side and subtype (geotropism vs dorsalis)

For subtype judgment, although relatively unfamiliar to neurologists, the value of this questionnaire lies in the first 3 questions
