Brief Summary

This randomized controlled trial aims to evaluate the effect of digital intelligence games on visual and cognitive performance in young individuals with intellectual disabilities. Participants aged 18-35 years receiving services from EÇADEM in Istanbul will be randomly assigned to either an intervention group receiving digital intelligence game training using the MentalUP application or a control group receiving routine services. Visual memory and cognitive performance will be assessed using the Benton Visual Retention Test and the Standardized Mini Mental Test at baseline, 3 months, 6 months, and 12 months. The study will investigate the short- and long-term effects of digital cognitive training on visual and cognitive functioning.

Outcome Measures

Primary Outcomes (2)

• Change in visual memory performance

  Visual memory performance will be assessed using the Benton Visual Retention Test (BVRT). The BVRT evaluates visual perception, visual memory, and visuoconstructive abilities by asking participants to identify previously presented geometric figures. Scores range from 0 to 15, with higher scores indicating better visual memory performance.

  Baseline, 3 months, 6 months, and 12 months

• Change in cognitive performance

  Cognitive performance will be evaluated using the Standardized Mini Mental Test (SMMT). The SMMT assesses orientation, attention, memory, language, and visuospatial abilities. Scores range from 0 to 30, with higher scores indicating better cognitive functioning.

  Baseline, 3 months, 6 months, and 12 months after baseline.

Study Arms (2)

Digital Intelligence Game Intervention

EXPERIMENTAL

Participants will receive digital intelligence game training using the MentalUP platform under supervision of a clinical psychologist and occupational therapist. Sessions will be conducted twice weekly and include structured cognitive exercises targeting attention, memory, and problem-solving skills.

Behavioral: MentalUP Digital Intelligence Game

Routine Care

NO INTERVENTION

Participants will receive routine services provided by EÇADEM without additional digital cognitive training.

Interventions

MentalUP Digital Intelligence Game BEHAVIORAL

MentalUP is a digital cognitive training platform designed to improve attention, memory, logical reasoning, and problem-solving abilities through adaptive intelligence games.
