SYNERGIC-2 Trial (SYNchronizing, Exercises and Remedies to GaIn Cognition@home)

Официальное название

A Home-based Personalized Multidomain RCT from the Canadian Therapeutic Platform for Multidomain Interventions to Prevent Dementia (CAN-THUMBS UP)

Обзор

In Canada, 1,700,000 adults are at risk of dementia, half of them with MCI,representing one of the largest groups at risk for an incurable disease. Epidemiological evidence suggests up to 40% of dementia cases might be preventable by targeting modifiable lifestyle and cardiovascular factors. Given that current treatments cannot modify the disease, prevention is critical. SYNERGIC-2 offers a "personalized multidomain intervention" that combines physical and cognitive training, sleep, diet, and vascular-metabolic interventions in individuals with MCI to synergistically enhance their overall brain health including cognition and contributes to maintaining their independence. Importantly, interventions will be provided at home using an existing virtual platform reducing delivery complexity and expanding the accessibility to a wider population, thus decreasing potential inequities. Improving older adults' brain health and achieving even a modest two-year dementia incidence delay will have a projected saving of $218 Billion in Canada's healthcare system over 30 years.

Подробное описание

Epidemiological evidence suggests up to 40% of potential dementia cases might be preventable by targeting modifiable lifestyle and cardiovascular factors; given that current treatments cannot modify the disease, prevention is a critical aspect. SYNERGIC-2 is the first large Canadian clinical trial using a 12-month home-based personalized multidomain lifestyle intervention to improve cognition in 550 older adults with Mild Cognitive Impairment (MCI), a pre-dementia state. These personalized at-home interventions target 5 domains with tailored physical exercise, cognitive training, diet recommendations, sleep interventions, and vascular risk factor management and are all delivered using a digital platform. Specifically, SYNERGIC-2 will be conducted with participants in their homes using video-conference meetings to test participants and to coach them 1-on-1 through the interventions on a web-based digital platform. The effect of these combined interventions on cognition will be compared to an online-educational program Brain Health PRO (BHPro). Both interventions are part of CAN-THUMBS UP, the interventional platform of the CCNA related to Canada Dementia Research Strategy; and constitutes Canada's contribution to the World-Wide-FINGERS Network. Importantly, these interventions have been selected because there is evidence that they synergistically enhance overall brain health including cognition and contributes to maintaining independence for individuals at risk for developing dementia.

  Personalized multidomain interventional program by combining tailored lifestyle interventions that targets 5 domains: physical activity, cognition, diet, sleep, and vascular risk factors. These interventions are tailored based on participants' baseline profile and progress in intensity following the principles of personalized medicine. All aspects of the PMI@home will be delivered remotely, at participants' homes, using a "digital platform" with scheduled bi-weekly 1-to1 coaching sessions. Deliv

Критерии участия

Критерии включения

• Ages 60-85 years.
• Having mild cognitive impairment (MCI) defined as meeting all of the following:

• Presence of subjective memory complaints from the participant and/or informant.
• Objective impairment on cognitive tests independent of outcome measures.†
• Preserved activities of daily living assessed (>14/23 in Lawton-Brody IADL score). For the study, impairment of daily living will be assessed based on cognitive abilities, not physical abilities.
• Absence of clinical dementia per DSM-IV criteria †Objective cognitive impairment is operationalized as: Montreal Cognitive Assessment (MoCA) total score between 16 and 25 (inclusive), and/or RAVLT delayed recall ≤6, and /or Clinical Dementia Rating Scale (CDR) =0.5
• Have ≥1 additional dementia risk factors targeted by our intervention as follows: low physical activity (less than 150 minutes of moderate-to-vigorous-intensity physical activity per week, as per GAQ), poor diet (14-item Mediterranean Diet Assessment (MDA-14) score ≤7), insomnia or subthreshold insomnia ( Insomnia Severity Index (ISI) score >7), and vascular-metabolic risk (Cardiovascular Risk Factors Aging and Incidence of Dementia (CAIDE) score ≥6 and/or diabetes (type I or II) and/or obesity (BMI≥30) and/or diagnosis of high blood pressure (hypertension) and/or smoking).

• Self-reported levels of proficiency in English for speaking and understanding spoken and written language.
• Have normal/corrected to normal vision in at least one eye to identify stimuli on computer/tablet screen.
• Have normal to corrected hearing ability, in order for the participant to engage in digital/virtual communication. Research personnel will determine and assess the hearing ability as per participant's performance.
• Able to comply with virtual visits, treatment plan, and trial-related activities.
• Ability to participate in the study's exercise training as determined by the Get Active Questionnaire (GAQ).

Критерии исключения

• Having a diagnosis of dementia (based on DSM-IV criteria).
• Underlying severe disease that precludes engagement with interventions, including presence of psychiatric diagnoses (i.e., major depression (Geriatric Depression Scale (GDS-30) >19), schizophrenia, severe anxiety, neurological disorder with severe motor deficits, such as current parkinsonism or any neurological disorder with residual severe motor deficits (i.e., stroke with motor deficit), or presence of unstable (non-controlled e.g., symptoms that suggest instability or no treatment for their condition) chronic disease such as congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD) that may preclude the participant from engaging properly with the trial interventions, or advanced-stage active cancer that at the study physician's discretion will prevent them from participating.
• Having had surgery within the last 2 months or having an upcoming planned surgery in the next 12 months that could interfere with the participant's vision, hearing, mobility, or any other abilities to participate in the study.
• Regular use of Benzodiazepine or neuroleptic drugs that may interfere with the participants ability to participate in the assessments and interventions.
• Recent (in the past 12 months) and/or current substance or alcohol abuse.
