Introduction: The mechanisms involved in the association between vestibular dysfunction and cognitive impairment are still unclear. Objective: to verify the correlation between vestibular exams and tests with cognitive abilities, functionality and depression in elderly people with vestibular dysfunction. Methods: cross-sectional, observational and analytical study. The sample consisted of 50 elderly people of both sexes, aged between 60 and 86 years. Elderly people with vestibular dysfunction confirmed by the Vestibular Evoked Myogenic Potential (VEMP) and Video Head Impulse Test (v-HIT) tests were included. Balance and the impact of dizziness on quality of life were assessed using vestibular tests and scales. Cognition, functionality and depressive symptoms were assessed in a quiet room using tests and scales. Univariate analysis was performed using the Spearman test. Variables that presented correlation ≤ 0.2 were selected for multivariate analysis by linear regression. A significance level of 5% was adopted (p< 0.05). Results: There was a correlation between vestibular dysfunction and imbalance with the results of the neuropsychological assessment (p=0.000), depressive symptoms (p=0.001) and functionality (p=0.002). Conclusion: In the present study, a correlation was found between vestibular dysfunction and imbalance with the worst clinical and functional indices, worse functionality, depressive symptoms and visuospatial function skills, executive functions and praxis.
