Cognitive interventions, especially cognitive training, may improve cognitive functions in healthy older adults. Computerized cognitive training platforms offer several advantages over traditional programs for cognitive training and stimulation. The focus of this article is the methodology of the studies that apply a particular online training program. We investigate the effectiveness of several studies for cognitive training in healthy elderly people and evaluate reported outcomes and potential bias and what factors determine, influence or contribute to the positive or negative results. The post-intervention scores demonstrate that computerized cognitive training may enhance some cognitive functions and the overall cognitive status but there is need for additional research to prove its effectiveness.

This paper reports the results from a three-years follow-up study to access the long-term efficacy of a cognitive training for healthy older adults and investigates the effects of booster sessions on the cognitive performance of the participants using an innovative analytical approach from information theory. Design: semi-randomized quasi-experimental controlled design. Participants: 50 healthy older adults, (M = 73.3, SD = 7.77) were assigned into an experimental (N = 25; Mean age = 73.9; SD = 8.62) and a passive control group (N = 25; mean age = 72.9; SD = 6.97). Instruments: six subtests of WAIS and two episodic memory tasks. Procedures: the participants were assessed in four occasions: after the end of the original intervention, pre-booster sessions (three years after the original intervention), immediately after the booster sessions and three months after the booster sessions. Results: the repeated measures ANOVA showed that two gains reported in the original intervention were identified in the follow-up: Coding (F(1, 44) = 11.79, MSE = 0.77, p = .001, ηˆG2 = .084) and Picture Completion (F(1, 47) = 10.01, MSE = 0.73, p = .003, ηˆG2 = .060). After the booster sessions, all variables presented a significant interaction between group and time favorable to the experimental group (moderate to high effect sizes). To compare the level of cohesion of the cognitive variables between the groups, an entropy-based metric was used. The experimental group presented a lower level of cohesion in three of the four measurement occasions, suggesting a differential impact of the intervention with immediate and short-term effects, but without long-term effects.

AbstractThe purpose of this study was to determine the immediate effects of cognitive training on healthy older adults and verify the transfer effects of targeted and non-targeted abilities. The design consisted of a semi-randomized clinical controlled trial. The final sample was composed of 80 volunteers recruited from a Brazilian community (mean age = 69.69; SD = 7.44), which were separated into an intervention group (N = 47; mean age = 69.66, SD = 7.51) and a control group (N = 33; mean age = 69.73, SD = 7.45). Intervention was characterized by adaptive cognitive training with 12 individual training sessions of 60 to 90 minutes (once a week). Eight instruments were used to assess effects of cognitive training. Five were used to assess trained abilities (near effects), including: Memorization Tests (List and History), Picture Completion, Digit Span, Digit Symbol-Coding, and Symbol Search (the last four from WAIS-III). Two instruments assessed untrained abilities (far effects): Arithmetic and Matrix Reasoning (WAIS-III). The non-parametric repeated measures ANOVA test revealed a significant interaction between group by time interaction for Picture Completion [F(74) = 14.88, p = .0002, d = 0.90, CLES = 73.69%], Digit Symbol-Coding [F(74) = 5.66, p = .019, d = 0.55, CLES = 65.21%] and Digit Span [F(74) = 5.38, p = .02, d = 0.54, CLES = 64.85%], suggesting an interventional impact on these performance tasks. The results supported near transfer effects, but did not demonstrate a far transfer effects.

BACKGROUND: Cognitive interventions have the potential to enhance cognition among healthy older adults. However, little is known of the factors associated with the joining and participating of older people in group-based multicomponent cognitive training (CT). OBJECTIVES: To explore factors that contribute to joining and regularly practicing CT over 1 year among healthy older adults. DESIGN: A qualitative study. SETTING: Geriatric clinic in Bangkok, Thailand. PARTICIPANTS: 40 nondemented community-dwelling older adults INTERVENTION: The CT of executive functions, attention, memory and visuospatial functions (TEAM-V) program was conducted over 5 sessions, with a 2-week interval between each session. MEASUREMENTS: An inductive qualitative approach, based on semi-structure interviews with 40 healthy older adults, was employed. The interviews explored factors of joining CT at baseline, factors of regularly participating in class at 6 months and at home at 1 year. Data were coded and analyzed using and the thematic analysis approach. RESULTS: After analyzing factors concerning joining CT, 3 core themes emerged: (1) individual characteristics with 3 subthemes of “health status”, “time arrangement”, and “financial status”; (2) individual perceptions with 2 subthemes of “perceived susceptibility to dementia” and “perceived severity of dementia” and (3) encouragement from families and friends. After analyzing factors of practicing CT in class, 3 core themes emerged: (1) program with 3 subthemes of “session”, “group facilitators” and “notification before class”; (2) accessibility with 2 subthemes of “distance” and “transportation” and (3) encouragement from families and friends. After analyzing factors of practicing CT at home, 2 core themes emerged: (1) contents of the training program and (2) encouragement from families and friends. CONCLUSIONS: Increased awareness of holistic factors including older adults’ characteristic and perceptions, support from families and friends and accessibility should be emphasized in planning CT. Designing the content of CT that could be applied or adapted in daily living and effective program components such as a notification system could increase practicing.
