Resumen

Cognitive stimulation in older adults can improve cognitive performance and help reduce the risk of developing cognitive decline. Objective: To analyze the effectiveness of computerized cognitive stimulation (CCS) on memory, attention, processing speed, and problem-solving in cognitively healthy older adults (OA). Method: The sample consisted of an intervention group (IG = 47, M = 76.02, SD = 3.37 years) subjected to 42 CCS sessions using Lumosity software three times per week, and a control group (CG = 52, M = 74.12, SD = 2.86 years) from the community, who did not receive any intervention. Both groups were medically evaluated and assessed using the Modified Mini-Mental State Examination (MMSEm), the Photo Test (PT), the Clock Test (CT), and the Trail Making Test (TMT A and B), before and after training. Results: At baseline, significant intergroup differences favored the CG in all cognitive tests (MMSEm: d = 0.92; TMT-A: d = 1.12; TMT-B: d = 1.14; PT: d = 0.55; CT: d = 0.50). Despite these disparities, post-intervention analysis showed significant improvements in the IG across all domains except the CT (t =-1.43, p = ns), with large effects in MMSEm (d = 0.86) and moderate effects in PT, TMT-A and B. Conclusions: CCS improved the cognitive performance of the evaluated older adults, demonstrating its feasibility and relevance as a digital strategy for cognitive health. © Medicinska naklada – Zagreb, Croatia.
