About this trial

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.

    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.

  • Brain health Psychoeducation

    Behavioral

    Delivery of psychoeducation sessions about dementia modifiable risk factors, brain health solutions and lifestyle change tips.

Trial outcomes

Primary outcomes

1

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.

Time frame
Post intervention (1 week after the intervention sessions completion)
2

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.

Time frame
Post intervention (1 week after the intervention sessions completion)
3

Blood biomarkers of neural damage

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

Time frame
Post intervention (1 week after the intervention sessions completion)
4

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

Time frame
Follow - up (12 months after the intervention)

Secondary outcomes

1

Brain changes

hippocampus volume and DMN connectivity will be measured pre and post intervention in the RCT phase

Time frame
Post intervention (2 weeks after the intervention sessions completion)
2

Mood status

The Geriatric Depression Scale Short Form (GDS-15) (0-15, with higher scores meaning worse outcomes) and and The Geriatric Anxiety Inventory- Short Form (GAI-SF, 0-5, with higher scores meaning worse outcome) scores will be measured

Time frame
Post intervention (1 week after the intervention sessions completion)
3

Mood status

The Geriatric Depression Scale Short Form (GDS-15) (0-15, with higher scores meaning worse outcomes) and and The Geriatric Anxiety Inventory- Short Form (GAI-SF, 0-5, with higher scores meaning worse outcome) scores will be measured.

Time frame
Follow-up (12 months after the intervention)
4

Perceived quality of life

A measure of quality of life - World Health Organization Quality of Life - Old WHOQOL-OLD)will be incorporated to examine the effects of the program in self perceptions of well being. Higher scores mean better outcome

Time frame
Post intervention (1 week after the intervention sessions completion)
