The Feasibility and Effect of Digital Cognitive Training in Mild Cognitive Impairment

The goal of this study is to assess the feasibility and effect of digital cognitive training based on the principles of Differential Outcome Training (DOT) in patients with Mild Cognitive Impairment. In DOT training, each stimulus-response pair to be learnt is followed by a unique reinforcer, as opposed to non-DOT (NDOT) training, where the stimulus-response pairs are all followed by a random reinforcer. DOT training is believed to boost learning more than NDOT training through associations. The main questions the study aims to answer are: * Whether at-home, tablet-based digital cognitive training is feasible in elderly patients with Mild Cognitive Impairment * Whether regularly digital cognitive DOT training has a positive effect on patients' cognitive functioning and quality of life * Whether any potential effects that the cognitive DOT training may have on the patients' cognitive functioning are transferable to the patients' daily life. Participation in the study includes: * A pre-training session at the site with the primary project coordinator, where the patient will complete a number of self-report questionnaires about their health, cognition, and quality of life as well as a neuropsychological assessment. * Training with the digital cognitive DOT training program at home for 20 min. per day 3-4 times a week for 6-8 weeks. * A post-training session at the site with the primary project coordinator after the 6-8 weeks have passed, where the patient will complete a usability questionnaire about the training programme, some of the same self-report questionnaires about their health, cognition, and quality of life as well as some of the neuropsychological assessments. * A 1-month follow-up session where the patients will complete some of the same self-report questionnaires again about their cognition and quality of life plus a questionnaire aimed the transferability of any positive cognitive effects of the training.
