This study will be a cross-over randomized controlled trial.~Fifty participants will be enrolled and randomly assigned to group A or group B.~Group A will self-administer Neuro-World cognitive training games for 30 minutes a day, twice a week for 12 weeks in the home setting (i.e., intervention period). For the following 12 weeks, the participants will not engage in any therapist-supervised cognitive therapies (i.e., no-intervention period).~Group B will not engage in any therapist-supervised cognitive therapies (i.e., no-intervention period). For the following 12 weeks, the participants will self-administer Neuro-World cognitive training games for 30 minutes a day, twice a week in the home setting (i.e., intervention period).~All the participants in both groups will receive phone calls twice a week to 1) provide feedback on their adherence to Neuro-World cognitive training (during the intervention period) and 2) learn any significant changes in the level of their daily activities (during the no-intervention period and the intervention period).
This study will evaluate the therapeutic efficacy of Neuro-World cognitive training games (Woorisoft, S. Korea) in patients with mild cognitive impairment.
