20 hours of digital cognitive training targeting executive function.

10 hours of computer games c available online which do not involve a high demand in cognitive functions (e.g. fishing game, pinball game, tetris, etc), followed by 10 hours of of digital cognitive training targeting executive function.

Digital cognitive exercises, used in the intervention group, have the primary objective of stimulating executive functions, and will be made available through the Internet using the BrainHQ platform.

Performance in everyday living score change will be measured using Canadian Occupational Performance Measure (COPM).

The Canadian Occupational Performance Measure (COPM) has a client-centered design and measures outcomes according to three occupational performance areas (self-care, productivity, and leisure), examining self-perceived changes in the occupational performance of patients through a semistructured interview. At the beginning, patients start by identifying their difficulties according to the three occupational performance areas. They subsequently use a 10-point scale, ranging from not at all crucial (1) to extremely crucial (10), to identify the intensity of certain difficulties. For the top five problems or tasks selected by patients, the interviewer asks them to continue identifying their performance and satisfaction with their performance by using the same 10-point rating scale.

Functional status score will be measured using the Direct Assessment of Functional Status-Revised (DAFS-R). DAFS-R assesses seven different domains of functional abilities by requiring the participant to carry out different tasks, two domains will be evaluated: dealing with Finances (score range 0-32) and shopping skills (score range 0-20), with higher scores indicating better functioning.

Global cognitive function score will be measured using the Montreal Cognitive Assessment (MoCA). Thirty items assessing multiple cognitive domains are contained in the MoCA: short-term memory (score range 0-5); visuospatial abilities (score range 0-3), cube copy task (score range 0-1); executive functioning (score range 0-1), phonemic fluency (score range 0-1), verbal abstraction (score range 0-2); attention, concentration, and working memory (score range 0-1), serial subtraction (score range 0-3), digits forward (score range 0-1), and digits backward (score range 0-1); language (score range 0-3), and repetition of complex sentences (score range 0-2); orientation to time and place (score range 0-6), with higher scores indicating better cognition.
