A Review on the Measures of Auditory Cognition in Individuals with Vestibular Disorders

Background and Aim: The vestibular system, which involves the peripheral vestibular apparatus and central vestibular pathways, is crucial for balance and posture. In addition to its primary functions, the vestibular system is closely linked with cognitive processes, as evidenced by its connections with the neocortex and limbic system. Vestibular dysfunction has been associated with cognitive impairments, particularly in areas of auditory cognition, where allocating cognitive resources for balance maintenance detracts from higher cognitive functions. This review examines the existing literature on the auditory-cognitive consequences of vestibular dysfunction. Recent Findings: This systematic review gives comprehensive information about the existing research on the impact of vestibular pathology on auditory cognitive abilities. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 226 articles were initially identified, with six studies meeting the inclusion criteria after thorough screening. The review highlights the varied effects of vestibular dysfunction on auditory cognition, revealing significant impairments in auditory working memory and attention, particularly in conditions like bilateral vestibulopathy and vestibular migraine. However, inconsistencies in the literature regarding specific vestibular pathologies and their impact on auditory cognition underscore the need for further targeted research. Conclusion: The findings suggest a complex interplay between vestibular function and auditory cognition, with implications for the diagnosis and management of cognitive deficits in individuals with vestibular disorders.
