Introdução: As intervenções multidomínios no âmbito da prevenção da demência têm demonstrado resultados consistentes e têm sido uniformizadas através do modelo FINGERS, sendo a dimensão cognitiva particularmente relevante. O treino cognitivo computorizado tem sido cada vez mais utilizado, mas a sua viabilidade em Portugal - onde a maioria das pessoas idosas tem baixo nível educacional e baixa literacia digital - continua a ser pouco estudada. Este estudo analisa a componente cognitiva do estudo DemenPrev, um estudo de viabilidade que adota o modelo FINGER.
Objetivos: Avaliar a adesão ao programa de treino cognitivo computorizado Brain HQ; avaliar a usabilidade do programa e a satisfação com a utilização do mesmo; avaliar as diferenças entre
a avaliação inicial e final.
Metodologia: O estudo decorreu com uma amostra de 21 pessoas idosas com média de idades de 71,9 (DP=3,58) com risco de demência, tal como avaliado pelo CAIDE. 18 participantes eram mulheres e 3 eram homens. A média de anos de escolaridade é de 9,7 (DP=4). As
avaliações iniciais geradas pelo programa eram compostas por 3 exercícios: Mind Bender (funções executivas), Target Tracker e Double Decision (atenção). Com base nesses resultados, os exercícios foram individualmente planeados pelo programa. Foram realizadas sessões
bissemanais com duração de 45 a 50 minutos durante 12 semanas. Pós intervenção, as reavaliações foram compostas pelos mesmos exercícios.
Resultados: A taxa de adesão ao estudo foi de 100% e a taxa de retenção foi de 95,2%, tendo os participantes expressado muita motivação para continuar este tipo de intervenção.
Observaram-se melhorias significativas nas avaliações pós intervenção nas áreas de funções executivas (Mind Bender, p=0.006) e atenção (Target Tracker, p=0.004; Double Decision, p<0.001). Os parâmetros de satisfação (motivação, participação, exigência, tempo e
esclarecimento de dúvidas) foram todos muito bem classificados pelos participantes. A usabilidade do programa foi igualmente bem avaliada. (M=71,63).
Conclusão: Não sendo possível estabelecer causalidade sem realizar um ensaio clínico, os resultados deste estudo apoiam o potencial deste tipo de intervenção, revelando um bom nível de viabilidade e aceitabilidade. Em estudos futuros, recomenda-se a realização de um ensaio clínico de grande escala.
Introduction: Multidomain interventions for dementia prevention have shown consistent benefits and have been standardized through the FINGERS model, with the cognitive dimension being particularly relevant. Computerized cognitive training is increasingly used, but its feasibility in Portugal – where many older adults have low educational levels and limited digital literacy – remains underexplored. This study analyses the cognitive component of DemenPrev, a Portuguese feasibility study adopting the FINGER model. Objectives: To evaluate (1) adherence to the computerized cognitive training program; (2) usability and satisfaction; (3) and differences between initial and final platform assessments. Methods: Twenty-one older adults with the mean age of 71.9 (SD=3.58) at risk for dementia, evaluated by CAIDE. Eighteen participants were women and three were man. The mean years of education were 9.7 (SD=4.0). Baseline assessment was conducted using three computerized exercises: Mind Bender (executive functions), Target Tracker and Double Decision (attention). Based on these results, individualized training plans were generated. Participants attended two 45–50 minute sessions per week over 12 weeks. Post-intervention, the same exercises were repeated for reassessment. Results: Adherence was very high (100%), as was retention (95,2%) and participants expressed strong willingness to continue. Significant improvements were observed in executive functions (Mind Mender, p=0.006) and attention (Target Tracker, p=0.004; Double Decision, p<0.001). Satisfaction parameters (motivation, engagement, demand, time, clarity) were rated from moderately to extremely satisfactory. Usability was highly rated by the group. (M=71.63). Conclusion: Although causality cannot be established without randomized controlled trials, these results support its potential as a promising non-pharmacological component of dementia prevention strategies, demonstrating good feasibility and acceptability. For future studies, a large-scale clinical trial is recommended.
