Evaluation of the Effect of Digital-based Games on the Visual and Cognitive Performance of Young Children With Intellectual Disabilities

This study is designed as an experimental, parallel-group, repeated-measures randomized controlled trial. The study aims to examine the effects of digital intelligence games on the visual and cognitive performance of young individuals with intellectual disabilities.

Participants will be recruited from EÇADEM (Engelli Çocuklar Aile Destek Eğitim Merkezi) located in Sarıyer district of Istanbul. Participants meeting the inclusion criteria will be randomly assigned to intervention and control groups using stratified block randomization according to the level of intellectual disability (mild and moderate).

The intervention group will participate in structured digital intelligence game activities using the MentalUP platform, conducted twice weekly under the supervision of a clinical psychologist and an occupational therapist. The control group will receive routine services provided by the center without additional intervention.

Data will be collected at baseline and at 3-, 6-, and 12-month follow-ups using the Benton Visual Retention Test and the Standardized Mini Mental Test. The study will evaluate both short-term and long-term effects of the digital intervention.

The study protocol follows the CONSORT guidelines for randomized controlled trials.
