Computerized Cognitive Training in Healthy Older Adults and Mild Cognitive Impairment (COGNI-AGE)
Computerized Executive Function Training in Healthy Older Adults and Individuals With Mild Cognitive Impairment: Transfer Effects on Memory and Emotional Outcomes. A Randomized Controlled Trial
研究概览
地位
详细说明
Population aging leads to an increase in the prevalence of cognitive decline, which negatively affects the autonomy and quality of life of older adults.
In turn, the mild cognitive impairment (MCI) is an intermediate state between normal aging and dementia. The impact of adaptive computerized cognitive training (CCT) specifically focused on executive functions in older adults with healthy cognition and MCI has not yet been sufficiently explored.
Additionally, the following stand out in both conditions: small sample sizes, limited duration, a lack of evidence regarding transfer effects to memory, insufficient knowledge of the actual impact on the emotional health, behavioral disorders, or quality of life, among other factors.
Among the main questions it aims to answer are:
- What are the initial differences in emotional symptoms (depression, anxiety), behavioral disorders, and quality of life between healthy older adults and adults with MCI, before the intervention?
- Are there any improvements in emotional and functional well-being following the program intervention?
- What are the effects of executive function training (adaptive CCT) on improving performance in executive functions?
- Is there a transfer from trained executive functions to untrained memory domains directly?
Recruitment is carried out in day care centers and nursing homes that have shown collaboration with the university and have agreed to conduct the study. This recruitment takes place in Spain, in different autonomous communities.
Participants aged 65 years and older will be randomly assigned to one of four experimental conditions, defined by the combination of cognitive status (healthy aging vs. MCI) and type of intervention (training vs. active control). Accordingly, four experimental groups will be established.
Participants in this study will complete three in-person assessments: baseline (prior to cognitive training), post-intervention, and a three-month follow-up assessment. Each assessment session will last approximately two hours per participant. Assessments will be conducted by a multidisciplinary research team composed of psychologists, neuropsychologists, and neuroscientists with expertise in cognitive aging and cognitive interventions.
The intervention will last between 8 and 12 weeks, with participants completing approximately two to three training sessions per week. Training sessions will be conducted in small groups (approximately 3-5 participants) under the supervision of a psychologist from the research team, in designated rooms within each residence equipped with tables and tablets provided by the research team.
The executive function cognitive training program will be implemented using the CogniFit platform (CogniFit Inc ©) in research mode.

描述
Inclusion Criteria:
- adults 65 years of age and older;
- spanish speakers;
- residents in Spain (urban and rural communities);
- elderly population that does not have dementia or other major diagnosed uncontrolled neurological disorders;
- the initial cognitive state will be determined by a global screening test, the Lobo's Mini Cognitive Examination, that is, the spanish version of the Mini-Mental State Examination (MMSE); and 6) all participants must provide their signed written informed consent indicating that the individual has been informed of the relevant aspects of the study (and may withdraw from the study at any time if they so request).
Exclusion Criteria:
- Older adults who obtain scores indicative of severe impairment (to be determined for low MEC scores that are suggestive of incipient dementia) or whose medical condition prevents them from participating safely;
- diagnosis of dementia (e.g., Alzheimer's disease or other);
- uncontrolled active major psychiatric illness (major depression, schizophrenia, etc.);
- significant uncontrolled neurological conditions or history (e.g., Parkinson's disease, stroke, severe traumatic brain injury);
- uncontrolled decompensated chronic medical conditions (e.g., diabetes, cardiovascular disease) that may affect cognition or attendance at sessions; and 6) severe uncorrected sensory disabilities (e.g., blindness or severe hearing loss) that interfere with the performance of tasks on tablets.

|
安慰剂比较:Group 1. Cognitively healthy older adults assigned to active control activities.
|
Participants in the active control groups (Group 1: healthy control; Group 3: MCI control) will also use the CogniFit platform.
However, in this condition, participants will engage in simple recreational computerized activities designed to control for screen exposure, participant engagement, and expectancy effects (e.g., digital coloring tasks, visual puzzles, and contour-tracing activities), without specifically targeting higher-order cognitive functions.
Participants will complete sessions lasting approximately 15-30 minutes, at least twice per week, over a period of 8-12 weeks.
|
|
实验性的:Group 2. Cognitively healthy older adults assigned to executive function cognitive training.
|
Participants in the experimental groups (Group 2: trained healthy individuals; Group 4: trained individuals with mild cognitive impairment) will use an online cognitive training platform (CogniFit®) consisting of multiple interactive games designed to train reasoning and executive functions.
Training activities will target key executive processes related to reasoning, including processing speed, planning, working memory updating, focused attention, cognitive flexibility, and response inhibition.
Each session will consist of several short games or exercises presented on a tablet screen, which participants will complete by following simple instructions and receiving immediate feedback on their performance.
Exercise difficulty will automatically adapt to participants' performance, as the activities are designed to impose a relatively high cognitive demand.
Participants will complete sessions lasting approximately 15-30 minutes, at least twice per week, over a period of 8-12 weeks.
