Vertigo is a medical condition where a person feels as if they or the objects around them are moving when they are not. Any disturbance in the functioning of vestibular organ may cause vertigo. This study aims to find the role of cervical Vestibular evoked myogenic potential in diagnosing BPPV. The study performed was a prospective study of 50 patients with the age distribution from 20 to 60 years of age, attending the OPD in ENT department of MY Hospital, Indore with complaints of Vertigo. c-VEMP test was performed. The results were evaluated to diagnose BPPV. Of all the patients with the complaints of vertigo maximum belonged to the 5th decade of life. Of all the patients, females were found to be affected more than males making the male female ratio to be 1:1.28. In our study Dix-Hallpike test was found to be positive in 38 (74%) patients. On performing cervical VEMP, 15 (30%) patients of 50 patients showed abnormal latencies and amplitudes suggesting abnormal saccular functioning on affected side. Of these 15 abnormal VEMPs, 13 patients were positive on performing Dix-Hallpike test i.e. were diagnosed to have BPPV. VEMP showed a positive correlation with Dix-Hallpike test in diagnosis of vertigo of postural origin and thus can be used as a diagnostic tool for BPPV as VEMP is found to have high specificity.

Benign paroxysmal positional vertigo (BPPV) is the most common cause for vertigo. It is diagnosed by the characteristic nystagmus induced by provocative positional tests. During these positional tests the patient experiences spinning vertigo and neurovegetative symptoms such as nausea and vomiting.

Background: Research evidence suggests the role of the vestibular system in cognitive functions like visuospatial memory, objective memory, spatial navigation, etc. Vestibular cortices send projection to the hippocampus and to the medial entorhinal cortex (MEC); the latter houses place cells, grid cells, and head direction cells, which play a major role in the formation of a cognitive map based on inputs from the vestibular apparatus. So, the present study aimed to assess cognitive functions in vestibular disorder patients.

Unlabelled: Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder characterized by brief episodes of vertigo triggered by changes in head position. Epley's manoeuvre and Semont's manoeuvre are widely used canalith repositioning procedures for the treatment of BPPV. This study aimed to compare the effectiveness of these two manoeuvres in treating post-canal BPPV in a cohort of 100 patients.

Article Synopsis
- Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness in older adults, particularly those aged 75 and up.
- A study in Gothenburg examined 887 participants, finding that 32% reported dizziness and the prevalence of BPPV was estimated at 4.5%.
- Many participants with dizziness declined testing due to fear and discomfort, suggesting that the actual rates of BPPV might be higher than reported.

: Even though BPPV is one of the most common causes of vertigo, it is often underdiagnosed and omitted in the diagnosis of patients reporting vertigo. The aim of the study was to establish a diagnostic pattern useful in patients admitted due to vertigo, based on the most common clinical characteristics of patients suffered from posterior canal BPPV (PC-BPPV), horizontal canal BPPV with geotropic (HCG-BPPV) and apogeotropic nystagmus (HCA-BPPV). : The analysis covered the results obtained in 105 patients with a positive result of the Dix-Hallpike maneuver or the supine roll test.
