Effectiveness of vestibular therapy as an adjunct to cognitive therapy to improve cognition in elderly with mild cognitive impairment (MCI)

The rapid global increase in aging populations is leading to a rise in age-related conditions like mild cognitive impairment (MCI), necessitating new treatment strategies. This study will conduct a double-blinded, three-arm, randomized controlled trial to evaluate the effectiveness of adding vestibular therapy to cognitive therapy (VT+CT) compared to cognitive therapy (CT) alone and a control group. Participants will be assigned to one of three groups: VT+CT, CT only, or a control group. The VT+CT group will receive vestibular rehabilitation exercises along with a computerized brain program, while the CT group will get only the computerized brain program. Primary outcomes will include electroencephalography (EEG), the Digit Symbol Substitution Test (DSST), and event-related potential (ERP-P300). Secondary outcomes will be the Stroop Color Word Test (SCWT), Trail-Making Test (TMT), and European Quality 5 Dimensions (EQ-5D-5L). This research aims to determine if VT+CT improves cognitive function in elderly individuals with MCI.
