Subjects belonging to this group perform a modern board game-based learning.

Subjects belonging to this group not perform intervention.

Modern board game-based learning involves using contemporary board games as educational tools. It emphasizes active participation, critical thinking, and social interaction among participants. By integrating strategic thinking and problem-solving within a game context, this approach aims to enhance learning experiences in an engaging and enjoyable manner. In this study, board games have been selected to target and engage executive functions.

The cognitive subscale "CAMCONG" is used, Section B of the CAMDEX-R (Cambridge Examination for Mental Disorders of the Elderly, adapted to Spanish by López-Pousa (2015)). It consists of 60 items (neuropsychological areas). The maximum score is 105 points in this revised option. In the scale validated by López-Pousa and others (1990), the cutoff point that best discriminated between a subject with dementia and one without dementia was 69/70. The scores for the different cognitive functions: orientation (minimun score 0, máximum score 10), language (minimun score 0, maximum score 30), memory (minimum score 0, maximum score 27), attention/calculation (minimum score 0, maximum score 9), praxis (minimun score 0, máximum score 12), abstract thinking (minimum score 0, maximum score 8), perception (mínimum score 0, máximum score 9). Minimum score: 0, total maximum score: 105. Executive function (maximum score is 28). A higher score indicates a better state of executive functions.

As a complement to assess executive functions, the TESEN (Trail Making Test to evaluate Executive Functions) is used, by Portellano Pérez and Martínez Arias (2014). It consists of four subtests (trails) where the evaluated person initiates increasingly complex cognitive processes and demands that measure functions such as working memory, prospective memory, motor processing speed, perceptual speed, inhibition, sustained attention, and alternating attention.

The TESEN provides three different scores for each trail, which are: execution score (E=hits-errors/time), speed score (V=time in seconds), and accuracy score (P=hits-errors/hits). In the quick correction mode, these values can be converted into decatips, a scale from 1 to 10, where the highest level indicates better development of executive functions.

The FUMAT scale (Gómez, Verdugo, Arias, and Navas, 2008) is an assessment instrument composed of 8 subscales that make up Quality of Life. In this study, the dimensions corresponding to will be used: emotional well-being (8 items, minimun score 8, maximum score 32); interpersonal relationships (6 items, minimun score 6, maximum score 24); personal development (8 items, minimum score 8, maximum score 32); social inclusión (9 items, minimun score 9, maximum score 36).
