Improvement of cognitive skills in elderly undergoing vestibular rehabilitation

Abstract

AbstractBackgroundstudies that used vestibular rehabilitation (VR) found improvement in cognitive abilities of spatial memory, visuospatial function, executive functions, attention and a decrease in psychological distress. However, these studies only used cognitive screening tests or did not include comprehensive neuropsychological assessment.Methodlongitudinal, observational, analytical and quasi‐experimental 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. The Geriatric Depression Scale ‐ short version (GDS‐15) was used to assess psychological distress and cognition was assessed using the Brief Neuropsychological Battery (Neupsilin). Psychological distress and cognition were assessed before and after eight sessions of vestibular rehabilitation according to the Cawthorne and Cooksey method (customized). Pre and post VR variables were detected using the Wilcoxon test. A significance level of 5% was adopted (p< 0.05).Resultafter vestibular rehabilitation, there was improvement in general cognition ‐ Neupsilin (142/145) and its subscales orientation (8/8), attention (12/20), memory (24/26), arithmetic skills (5/7), oral language (20/21), written language (28/29), praxis (12/14.5), executive functions (5/6) and decrease in psychological distress ‐ GDS‐15 (5/3).Conclusionafter vestibular rehabilitation, the elderly showed improvement in general cognition, orientation skills, memory, arithmetic skills, oral and written language, praxis and executive functions. Also note the decrease in psychic suffering.
