Yaşlılarda Hafif Bilişsel Bozukluğun Vestibülooküler Refleks, Dinamik Görsel Keskinlik ve Postüral Denge ile Etkileşimi

Abstract

Approximately 30% of the elderly population is falling each year, resulting in a major health problem. Cognitive decline is an independent risk factor for fall. Mild cognitive impairment is a cognitive decline that is higher than expected in the individual's age but does not affect the activities of daily living. In the study, vestibulo-ocular reflexes, dynamic visual acuities and postural balances of individuals with mild cognitive impairment were evaluated and compared with the healthy control group. For this purpose, 10 individuals with mild cognitive impairment and 10 healthy individuals from the same age group were included in the study. After the hearing test was applied to the individuals, videonistagmography, dynamic visual acuity and computerized dynamic posturography measurements were performed. Dynamic Visual Acuity Perception Time Test scores of the individuals with mild cognitive impairment were significantly longer compared to the control group (p <0.05). Computerized Dynamic Posturography VEST parameter, SOT 2, SOT 3, SOT 6 and Composite Balance Scores were significantly lower in the MCI group. There was no significant difference between the two groups in terms of videonistagmographic measurements. As a result of the study, it was concluded that individuals with mild cognitive impairment were more prone to fall compared to their healthy peers and that these individuals should be included in fall prevention rehabilitation programs.
