Brief Summary

Until now, neuropsychological interventions aimed to optimize cognitive function and to have functional impact in individuals at risk of AD (MCI patients) were scarce in validity studies. While some RCTs have been developed in cognitive training interventions, comparative studies of merged interventions (cognitive, social and behavioral stimulation) with adequate control groups are absent, diminishing the professionals' trust on the adoption of these interventions for supporting patients. As such, the present proposal will develop a validation trial testing a multicomponent neuropsychological intervention (REMINDER), based on personal development, cognitive compensatory aids, meaningful goals setting, and behavior change techniques. The investigators will analyze its short/long-term gains and AD conversion rates. By aiming to provide a good validation study for REMINDER, the investigators will examine neurobiological, neurocognitive and functional outcomes of this intervention in comparison with an active control group (psychoeducation) in order to foster an effective outcome assessment of an intervention for individuals at risk of AD.

Outcome Measures

Primary Outcomes (7)

  • Cognitive status composite

    A composite score including the individual scores with Addenbrooke's Cognitive Examination - Revised (ACE-R) (0-100, higher scores meaning better outcome), that includes the Mini Mental State Examination - MMSE (0-30, with higher scores meaning better outcome), Subjective Cognitive Decline Questionnaire (SCDQ), Trail Making Test A and B (TMT A \& B), Verbal Fluency - Phonemic (P, M and R) and Categories (Animals), Stroop Test, Free and Cued Selective Reminding Test (FCSRT) will be generated to work as primary outcome.

    Post intervention (1 week after the intervention sessions completion)

  • Functionality status

    A composite score incorporating Adults and Older Adults Functional Assessment Inventory (IAFAI), University of California San Diego Performance-Based Skills Assessment (UPSA) will be used.

    Post intervention (1 week after the intervention sessions completion)

  • Blood biomarkers of neural damage

    blood Neurofilament light chain (NfL) will be measured and tested as an outcome immediately after the intervention

    Post intervention (1 week after the intervention sessions completion)

  • Cognitive status composite

    A composite score including the individual scores with Addenbrooke's Cognitive Examination - Revised (ACE-R), that includes the Mini Mental State Examination - MMSE (screening tools to consider eligibility), Subjective Cognitive Decline Questionnaire (SCDQ), Trail Making Test A and B (TMT A \& B), Verbal Fluency - Phonemic (P, M and R) and Categories (Animals), Stroop Test, Free and Cued Selective Reminding Test (FCSRT) will be generated to work as primary outcome

    Follow - up (12 months after the intervention)

  • Functionality status

    A composite score incorporating Adults and Older Adults Functional Assessment Inventory (IAFAI), University of California San Diego Performance-Based Skills Assessment (UPSA) will be used.

Study Arms (3)

REMINDER program online

EXPERIMENTAL

The REMINDER program in this arm will be delivered by videoconferencing. It will integrate 20 sessions (with approximate length of 45-60 min), therapist-mediated, carried out twice a week, over a period of 12 weeks. Psychoeducation sessions and part of the reminiscence and memory strategies training sessions will be facilitated in groups, as means to promote social support and modeling, and the remaining will be individual sessions. Several activities aimed to promote personal development and definition and achievement of meaningful goals will be included in the program, and the program will be manualized to facilitate its future dissemination and implementation

Interventions

REMINDERBEHAVIORAL

The REMINDER program is a therapist-mediated manualized neuropsychological intervention, involving training skills to stimulate cognitive reserve, socialization and personal development, to diminish the risk of cognitive decline.
