The Incidence of Benign Paroxysmal Positional Vertigo (BPPV) in Patients Admitted to an Acquired Brain Injury Unit
Published online by Cambridge University Press: 11 August 2014
Abstract
Objective: Brain injury is described as one potential cause of benign paroxysmal positional vertigo (BPPV); however, there is little information regarding the actual incidence in people who have suffered a brain injury. The objectives of this study were to determine the incidence of BPPV in a group of inpatients with a brain injury and to document the pattern of recovery.
Methods: A retrospective chart review was used to collate data associated with dizziness and BPPV for all inpatients admitted to an acquired brain injury (ABI) unit over 1 year.
Results: Data from 89 individuals were collated. Forty-three individuals reported dizziness and 13 of these were clinically diagnosed with BPPV. All cases of BPPV occurred in individuals with traumatic brain injury (TBI) with 17.6% of this diagnostic group affected. Over half the cases were diagnosed with bilateral BPPV. Seventy per cent of individuals with BPPV required multiple treatments to resolve all symptoms.
Conclusions: Forty-one per cent of the inpatients who reported dizziness, and were able to be assessed, received a clinical diagnosis of BPPV. The study highlights the high incidence of BPPV following TBI, the importance of specifically enquiring about vertigo symptoms and undertaking appropriate assessment, and the increased complexity of treating BPPV in this group.
