Vestibular system is essential for balance control, perceptive-motor functions, it is also related to cognitive functions, which include attention, memory, visuospatial abilities and executive functions and it is very relevant to spatial navigation and spatial memory. From reviewing several studies that suggest that vestibular function is associated with several cognitive functions, in 2015 a conceptual model was proposed regarding the implications of peripheral vestibular dysfunction in the atrophy of certain cortical areas, which could explain deficits in visuospatial abilities, memory, attention and executive functions in subjects with vestibular or cognitive pathology. The objective of this study was to describe the association between vestibulo-collic activity and neuropsychological performance in a group of adults aged 65 to 84 years, with no clinical history of vestibular pathology and who performed well in a cognitive screening. Results show inverse associations between the magnitude of the vestibulo-collic activity and the performance in short-term memory, working memory and social cognition tasks; and statistical positive associations between vestibular activity and executive/visuospatial performance. In addition, statistics indicate that an altered vestibulo-collic reflex activity, measured using cVEMP, triples the probability of presenting an altered cognitive diagnosis. The results are not generalizable to the elderly population due to the size of the sample. Future research must be focused on testing vestibular function using other techniques and cognitive tests that measure spatial navigation and spatial memory abilities to assess adult and elderly population with cognitive and vestibular pathology to describe more probable associations and stablish comparisons between groups.
