简要总结
Normal ageing presents subtle cognitive changes that can be detected before meeting the criteria for Mild cognitive impairment (MCI). Older people with low cognitive reserve and who receive limited cognitive stimulation are at greater risk of deterioration. In this regard, cognitive stimulation (CS) has been identified as an intervention that reduces this risk, provided that its design considers the differences in the level of cognitive reserve (CR) acquired throughout life and the baseline level of cognitive functioning. The general objective of this study is to evaluate, through a randomized clinical trial, the effectiveness of a computerized cognitive stimulation program, designed and adapted from Occupational Therapy based on the level of cognitive reserve in older adults in Primary Care. 100 participants will be randomized in a stratified manner according to the level of cognitive reserve (high/low), assigning 50 participants to the control group and 50 participants to the intervention group. The intervention group will carry out a computerized cognitive stimulation intervention designed and adapted from occupational therapy according to the level of cognitive reserve, through the "stimulus" platform. The main result expected to be achieved is the improvement of higher brain functions. As secondary results, the investigators expect that those cognitive aspects most vulnerable to ageing will decrease more slowly (in areas such as memory, executive function, attention and processing speed) and that the cognitive reserve of the participants will increase, in addition to being able to balance gender differences in these aspects. The investigators think that these results can positively impact the creation of adapted, meaningful and stimulating CS programs in older adults to prevent MCI and experience healthier ageing.

结局指标
主要结局
Cognitive Reserve Questionnaire (CRQ)
时间窗: An initial evaluation (pre), post-intervention (in a period of 2 to 7 days after the last intervention session) and two follow-up evaluations (at 6 and 12 months) will be carried out.
To determine the level of cognitive reserve (Landenberger et al., 2019) the most suitable questionnaire is the Cognitive Reserve Questionnaire (CRQ) (Rami et al., 2011). It has eight items with between three and six response options. Each item relieves a CR factor: schooling, parental schooling, courses, occupation, musical training, languages, reading and intellectual games. The maximum score is 25 points. Between 7 and 9 points is considered a medium-low range of CR. Between 10-14 points medium-high range, and ≥15 points, high CR. It is an instrument with high reliability and acceptable convergent validity (Martino et al., 2021).
MEC-35 (Spanish version of Folstein's Mini-Mental)
时间窗: An initial evaluation (pre), post-intervention (in a period of 2 to 7 days after the last intervention session) and two follow-up evaluations (at 6 and 12 months) will be carried out.
The primary outcome variable is MEC-35 (Spanish version of Folstein's Mini-Mental): the most widely used cognitive test in Primary Care, adapted by Lobo to the Spanish population (Lobo, A., et al 1979). It evaluates 8 components: temporal orientation, spatial orientation, fixation memory, attention, calculation, short-term memory, language and praxis. Its sensitivity is 85-90% and its specificity 69% (Lobo, A. et al 1999). Although its cut-off point for detecting cognitive impairment is 24, in NC, scores between 28-35 points are considered (Friedman et al., 2012; Vinyoles Bargalló et al., 2002).
