INTRODUCTION: This study was aimed to investigate the effect of multimodal intervention on the cognitive functions of older adults with subjective cognitive impairment (SCI). MATERIALS AND METHODS: Sixty subjects were randomized 1:1:1:1 to receive either computer based cognitive therapy (CBCT) or CBCT plus Mediterranean equivalent diet (MED) or CBCT plus MED plus Exercise regime and the control group. The intervention group received supervised CBCT twice a week to have 40 sessions, each of 40 minutes duration, and/ or supervised aerobic and resistive exercise twice a week for 24 weeks and or MED at home under the supervision of a dietician. The control group was provided with health awareness instructions for brain stimulating activities such as sudoku, mental maths, and learning music and new skills. RESULTS: Cognitive functions which was the primary outcome measure were assessed using the Post Graduate Institute Memory Scale (PGI-MS), and Stroop Colour and Word Test at baseline and after 6 months intervention period. As assessed by the PGI-MS, there was significant improvement in domains such as mental balance, attention and concentration, delayed recall, immediate recall, verbal retention of dissimilar pairs, visual retention, and total score both in the unimodal and multimodal intervention groups. However, the improvement was observed to be the highest in the multimodal intervention group as compared to unimodal group. All the participants completed the trial. CONCLUSION: This pilot randomized control trial indicated that multimodal intervention could be an effective non-pharmacological intervention in individuals with SCI for improving their cognitive functions.
