2. CCNA Central Research Support
In CCNA Phase III, the creation of a Central Research Support was a significant milestone aimed at catalyzing and supporting research efforts across various domains. Central Research Support comprises several specialized programs designed to provide comprehensive guidance, resources, and collaboration opportunities to enhance the quality and impact of dementia research.
These programs include:
- Knowledge Mobilization
- Training and Capacity Building
- Indigenous Cognitive Health Program
- The Engagement of People with Lived Experience of Dementia
- Women Sex Gender and Dementia
These programs will be available to support successful CCNA Phase III research teams and cannot be accessed during the development of your application.
2.1 Knowledge Mobilization (KM)
The Knowledge Mobilization (KM) program will be available to provide consultation and guidance on:
- Expanding and refining the project's KM plan including key messages, KM goals, and KM products that will support the goals.
- Tailoring KM products to specific audiences, for example, adapting scientific language to plain language.
- Disseminating KM products, including leveraging CCNA partnerships, when appropriate.
- Engaging relevant knowledge users throughout the project.
- Evaluating the achievement of KM goals.
- Using relevant evidence from the KM scientific literature and KM tools.
2.2 Training and Capacity Building (TCB)
The Training and Capacity Building (TCB) program will:
- Maintain an online resource library for trainees to access training for developing skills related to the logistics of conducting research, how to prepare research proposals, how to prepare and build a successful grant application, budgeting, research standards, and ethics submissions.
- Act as a central research support for trainees on best practices regarding how to access and work with the Comprehensive Assessment of Neurodegeneration and Dementia Study (COMPASS-ND) study data using the Longitudinal Online Research and Imaging System (LORIS) platform.
- Foster networking and career development of trainees through networking opportunities such as the CCNA's annual scientific meeting - "Science Days and Partners Forum."
- Provide interdisciplinary training and capacity building by continuing to build our existing CCNA Investigator Member database, connecting mentors and mentees for one-year mentorship experiences. Investigators in Phase III will be invited and strongly encouraged to join our mentor pool and may be matched with mentees based on alignment of: (i) mentors' experiences, areas of expertise, and research interests, with (ii) mentees' research interests, career stage and goals, and identified areas of growth.
2.3 Indigenous Cognitive Health Program (ICH)
The Indigenous Cognitive Health (ICH) program will be available to provide consultation and guidance on:
- Indigenous data access and publication requests.
- Capacity building for Indigenous-led and Indigenous-informed research.
- Capacity building for Indigenous-led and Indigenous-informed knowledge mobilization.
2.4 The Engagement of People with Lived Experience of Dementia (EPLED)
The Engagement of People with Lived Experience of Dementia (EPLED) program works to enable those with lived experience of dementia (i.e., people living with dementia, caregivers/care partners, friends and family) to be meaningfully and actively involved in research. The EPLED program will be available to provide consultation and guidance to Research Teams on engaging people with lived experience of dementia in their proposed research. The EPLED program will also facilitate engagement activities in the proposed research, if the research aligns with the interests of the EPLED Advisory Group or its individual members.
2.5 Women Sex Gender and Dementia (WSGD)
The Women Sex Gender and Dementia (WSGD) program will be available to provide consultation and guidance on:
- Incorporation of sex and gender into research design for specific projects.
- Determining the sex and gender knowledge and knowledge needs of dementia researchers.
- Using sex and gender methods and measures through webinars/talks/access to resources.
- Mining the COMPASS-ND with a sex and gender lens.
- Considerations of inclusion, diversity, equity, accessibility, and intersectionality in dementia research.
- Inclusion of sex and gender in programs and publications in professional societies.
- Evaluating the achievement of the incorporation of sex and gender in dementia research.
3. CCNA Data and Biological Samples
3.1 Overview

3.1.1 Data Collected
Collected data include extensive clinical, cognitive, and neuropsychological measures, as well as objective sensory measures, clinically verified diagnoses, psychosocial and neuropsychiatric measures, and study partner questionnaires. In addition to alphanumeric data, the study also captures standardized 3T neuroimaging, recorded speech, and biological samples that yielded plasma, serum, and cerebrospinal fluid (CSF) biomarkers as well as genetic data. Saliva samples collected cohort-wide are currently undergoing microbiome analyses, and these results are currently not available.
The deeply-phenotyped data are collected over multiple, in-person visits; together, these visits capture the Initial (Baseline) data for the study. A list of data instruments and measures can be found in Appendix A: COMPASS-ND Baseline Data.

3.2 Data Access
CCNA is committed to maximizing the use of data by Canadian scientists. Study data are housed on LORIS, CCNA's data management platform.
3.2.1 Process for Data Access Request
- Once funded, all teams (i.e. Nominated Principal Investigators [NPI]) will obtain a LORIS account by going to: LORIS.
- Funded teams will complete a data access request which is adjudicated by the COMPASS-ND Data Access Subcommittee (DASC), a sub-committee of the CCNA Publications and Data Access Committee (PDAC). An expedited process will be implemented to review the data access request for funded teams.
- Funded teams will work with the COMPASS ND Data Access Subcommittee to ensure all project plans abide by CCNA's legal and ethical parameters. Every reasonable attempt will be made to meet the needs of those funded. Course corrections to project plans will be implemented, as appropriate, based on the outcome of this process.
3.3 Fluid Biomarkers and Biological Sample Access
Biological samples were collected on 95% of the study participants at the time of the Initial Assessment. Plans are in place to collect longitudinal samples, but this work has not yet been undertaken. Collected biosamples include blood, saliva, and urine, as well as cerebrospinal fluid (CSF) in approximately 13% of participants. Extensive, routine analyses have already been carried out on the existing samples, yielding plasma, serum, and CSF biomarkers as well as genetics. Please see Appendix B: COMPASS-ND Fluid Biomarker Data for the list of results available in the LORIS database.
In addition to running routine analyses on the collected biological materials, the study has stored samples of these materials at the Canadian Biosample Repository (Edmonton, Alberta) for future research projects. In the scope of this funding opportunity, researchers are permitted to study biomarkers beyond those measured in COMPASS-ND by undertaking the sample request process outlined below and running their own analyses.
3.3.1 Process for Fluid Biomarkers and Biological Sample Access Request
- Once funded, all teams (i.e. Nominated Principal Investigators [NPI]) will obtain a LORIS account by going to: LORIS.
- Funded teams will complete a biological sample access request on the LORIS platform. Projects will need to detail the materials required for their research and may request biological material from a reasonable number of participants up to a maximum of:
- 1.0mL for serum, plasma, urine, or saliva;
- 1 vial for buffy coat; or
- 0.5mL for CSF.
- All requests are adjudicated by the CCNA Biological Samples Access Committee (BSAC). An expedited process will be implemented to review the biological samples access request for funded teams.
- Funded teams will work with the BSAC to ensure the availability of the material and to ensure all proposed plans abide by CCNA's legal and ethical parameters.
- Every reasonable attempt will be made to meet the needs of those funded. Course corrections to project plans will be implemented, as appropriate, based on the outcome of this process.
- A material transfer agreement will apply to any approved project. The cost of sample preparation and shipping should be factored in, as needed.
