Dementia research must include voices of those with lived experience

New Canadian study highlights barriers, best practices, and strategies for inclusion

2026-02-05

(Press-News.org) A new Canadian study has found that people living with dementia (PLWD) are often excluded from research due to assumptions of incapacity and variations in institutional processes. The authors argue that with rights-based, supported approaches, PLWD can participate meaningfully in decisions that affect their lives.

“To ignore the PLWD from research is to exclude a critical piece of information that may affect research outcomes,” says Jim Mann, an advocate living with dementia and co-researcher in the study.

The study, based on interviews with dementia researchers across Canada, reveals how a range of research processes such as funding, ethics approval, participant recruitment and forms of involvement often err on the side of protectionism, inadvertently silencing the voices of those most affected. The study’s authors call for standardized, rights-based guidance across Canadian institutions to support the meaningful inclusion of PLWD.

“Our findings show that exclusion is rarely inevitable; it is designed into systems and thus, can also be redesigned through intentional, inclusive and rights-based approaches,” says Dr. Amanda Grenier of the Institute for Life Course Studies at the University of Toronto. “Inclusion is not just ethical; it is a legal and human rights imperative under frameworks like the UN Convention on the Rights of Persons with Disabilities.”

The team offers six actionable recommendations for Canadian research institutions, including:

studying the effects of excluding PLWD on research quality and participant wellbeing; revising research processes to reflect supported decision-making and ongoing consent; developing guidelines to facilitate participation compliant with Canadian laws; offering a range of research roles that recognize and include PLWD; applying equity, diversity, and inclusion frameworks to achieve comprehensive inclusion; and educating ethics boards, institutions, and emerging researchers on dementia, consent, and human rights to ensure full and meaningful participation of PLWD. Strategies for inclusion identified by the study’s authors include involvement in capacities such as co-design, advisory committees, flexible and supportive consent procedures, and relationship-building with participants and care providers. By adopting flexible and creative research practices, and treating consent as a supported ongoing conversation, investigators can ensure that the insights gathered reflect the knowledge and insights of PLWD as well as needs that fluctuate over time.

The study’s authors argue that by implementing the recommendations Canadian research institutions can ensure that people living with dementia are recognized as meaningful contributors, while also reducing institutional risk and enhancing the relevance and quality of dementia research. This is best summed up by one of the researchers interviewed for the study, who said: “There's a huge practice gap that needs to change”.

Select quotes from Canadian dementia researchers who participated in the study

“I realized…staff were always wanting to put the most able residents into the program. So, there was that auto exclusion […] this idea that people who had more advanced symptoms…wouldn't enjoy it or wouldn't be able to participate.”

“Ethics boards and ethics reviewers are wanting to be very protective. They run under a risk model. Minimize, risk, protect, protect, protect…. [In] community driven research, we respect the fact that people live at risk. People can choose to have risk. That's their right, that’s their choice.”

“It's really important that research is grounded in [lived] experience…and the troubling issues for them [PLWD]. That should feed into decision-making about what we're going to do and what type of outcomes we're going to look at in a study”, noted another researcher.

Natto your average food

2026-02-05

Supersulfide molecules, metabolites from plants that are important in cellular metabolism, are attracting attention in the medical and nutritional fields for their potential in supporting health and disease prevention. Natto, a Japanese food made from soybeans fermented with the Bacillus subtilis var. natto microorganism, is rich in these molecules. However, the mechanism by which they are produced during fermentation has remained unclear. To better understand this complex process, a research group led by Professor Hideshi Ihara at Osaka Metropolitan University’s ...

Family dinners may reduce substance-use risk for many adolescents

2026-02-05

A new study from researchers at Tufts University School of Medicine finds that regular family dinners may help prevent substance use for a majority of U.S. adolescents, but suggests that the strategy is not effective for youth who have experienced significant childhood adversity. The findings provide important insights for practitioners looking to help families prevent substance use, as well as for researchers aiming to develop interventions that better account for adolescents’ unique experiences. For the study, ...

Sustainable electrosynthesis of ethylamine at an industrial scale

2026-02-05

From dyes to pharmaceuticals to emulsifiers - ethylamine (EA) is a versatile component used in many industries. The downside of EA is that its production is terribly complicated and energy intensive. However, it is not a simple task to simplify EA production in a way that can also be scaled up to industrial levels. Researchers at Tohoku University's WPI-AIMR may have found an answer to this problem. Rare earth Eu atoms were modified on Cu2O nanoneedles to produce a catalyst (Eu-Cu2O) that can increase the efficiency of ...

A mint idea becomes a game changer for medical devices

2026-02-05

Australian researchers have developed a high‑performance coating made from peppermint essential oil that can be applied to the surfaces of many commonly used medical devices, offering a safer way to protect patients from infection and inflammation. Matthew Flinders Professor and senior author of the new study, Professor Krasimir Vasilev, says the idea emerged after noticing that eating peppermint leaves from his drink significantly relieved his sore throat, inspiring him to explore whether its bioactivity could be converted into a durable coating using ...

Tropical peatlands are a major source of greenhouse gas emissions

2026-02-05

In Indonesia, Malaysia, and other parts of Southeast Asia, vast areas spanning up to 300,000 square kilometers have emerged over thousands of years as plants grow and thrive in dense tropical peat swamp forests, then die and slowly decompose in waterlogged, low-oxygen conditions. As a result, large amounts of carbon get stored in the soil rather than released into the atmosphere. Heavy rainfall keeps these landscapes flooded for much of the year, allowing layers of dead vegetation to build up and gradually compress into dense, carbon-rich peat. New research from Hokkaido University suggests that the ...

From cytoplasm to nucleus: A new workflow to improve gene therapy odds

2026-02-05

Gene therapy holds the promise of preventing and curing disease by manipulating gene expression within a patient's cells. However, to be effective, the new gene must make it into a cell’s nucleus. The inability to consistently, efficiently do so has hampered progress in advancing treatment. University of California San Diego researchers, led by Department of Biochemistry and Molecular Biophysics Professor Neal Devaraj’s lab, have unveiled a new method that greatly increases the efficacy of gene delivery while minimizing harmful side effects to the cell. Their work appears in Nature Communications. For ...

Five mutational “fingerprints” could help predict how visible tumours are to the immune system

2026-02-05

Cancer cells carry thousands of mutations, but not all mutations are created equal. Some make tumors highly visible to the immune system, while others help cancers hide. In this study, researchers have discovered that across thousands of human cancers, there are five dominant patterns of protein-altering mutations — called amino acid substitution signatures — and these patterns help determine how tumors interact with the immune system. When DNA in a cell is damaged by environmental exposures (like tobacco smoke or UV light) or internal errors during replication and repair, the resulting mutations change the building ...
