A recent study of nearly 1,800 participants from the UK Biobank found that three dietary elements — cheese, wine, and lamb — may improve long-term cognitive outcomes in aging adults. Dr. Auriel Willette, assistant professor of food science and human nutrition at Iowa State University, joins the podcast to discuss these new findings linking diet and cognitive changes. In November 2020, Willette published a study in the Journal of Alzheimer’s Disease titled “Genetic Factors of Alzheimer’s Disease Modulate How Diet is Associated with Long-Term Cognitive Trajectories: A UK Biobank Study,” where he and his team studied the effects of particular foods on a person’s brain health over time. As well as the findings surrounding cheese, wine, and lamb, they found that limiting salt intake was good for the brain, especially for those at risk for Alzheimer’s disease. Discussing the field of nutritional research, his prior work studying diet and brain health, and how these findings impact other recommended diets, Willette provides insight into how our current diets can impact our health and cognitive abilities later in life, allowing us to make better choices for the future.

Guest: Auriel Willette, PhD, associate professor of food science and human nutrition, Iowa State University.

With the numerous efforts currently focused on educating the public about dementia, from clinical programs to research to podcasts (like this one), how much is stigma surrounding cognitive decline affecting public understanding? On today’s podcast, Sarah Lock, Senior Vice President for Policy for AARP, discusses just that. This year, the AARP published a report on a survey focused on how the general American population and particular subgroups perceive dementia and dementia diagnoses. The survey found that the general public and health care professionals have many misperceptions about dementia, including overestimations about their likelihood to develop dementia and the shame they might feel about a diagnosis. Describing the contrasting perceptions between clinicians and the public and the impacts of stigma on dementia policy, Lock details the ways this survey will allow the AARP to build on their existing programs about brain health to better educate the public about dementia and the ways it affects a person’s life.

When talking about dementia caregiving, researchers are often working toward new treatments and strategies for supporting people with Alzheimer’s disease and dementia. But how can we push the topic further and learn how we can better support dementia caregivers themselves? Dr. Eric Larson joins the podcast to discuss possible interventions to support patients with dementia and their caregivers and care partners. Dr. Larson chaired a National Academy of Medicine committee focused on researching dementia caregiving interventions. As part of their report titled “Meeting the Challenge of Caring for Persons Living with Dementia and Their Care Partners and Caregivers: A Way Forward,” the committee found that two models, the Collaborative Care Model and REACH (Resources for Enhancing Alzheimer’s Caregiving Health), had the most evidence of benefits for supporting people with dementia and their care partners and caregivers. Discussing this new report, the recent approval of aducanumab, and the field of geriatrics as a whole, Dr. Larson shines a light on the nuances of dementia research and dementia caregiving.

Vince Tien and Dr. Dung Trinh join the podcast to discuss the many ways Alzheimer’s disease affects the Asian Americans and Pacific Islanders (AAPI) community. Vince Tien and Dr. Trinh both work as part of 360 Clinic, a multi-specialty medical group focused on telehealth services. With their experience in healthcare and telehealth services amidst the pandemic, Tien and Dr. Trinh describe the barriers and stigma that discourage the AAPI community from seeking help for dementia and the ways that we can dismantle those barriers. 

Guests: Vince Tien, co-founder, CEO, 360 Clinic, and Dung Trinh, MD, chief medical officer, 360 Clinic

What would happen if caregiving strategies were inspired by wonder rather than memory? That’s what Dr. Anne Basting, founder and president of the nonprofit TimeSlips, asked when she began her research into how the arts could be integrated into dementia caregiving. Basting joins the podcast to discuss her caregiving approach rooted in creative engagement and imagination. From storytelling to beautiful questions to performance, Basting describes a new way of caregiving that helps caregivers and families meet patients and loved ones where they’re at to have meaningful connections and spark joy in the later years of life.

Guest: Anne Basting, PhD, professor of English at the University of Wisconsin-Milwaukee, founder and president of TimeSlips, author of Creative Care

Researchers have produced many studies on how smoking affects parts of the body, such as the lungs or heart, but what about the brain? In today’s podcast, Adrienne Johnson, PhD, discusses her research on cigarette smoking and risk for dementia and Alzheimer’s disease. As part of a 2021 study, she found a person’s risk for dementia and Alzheimer's disease can be affected by how recently they’ve smoked. Diving into her research, the effects of smoking on different communities, and resources to support current smokers as they quit, Dr. Johnson details the impact of smoking on the brain and her hopes to develop new interventions to motivate smokers to quit for good.

Guest: Adrienne Johnson, PhD, assistant scientist at the University of Wisconsin Center for Tobacco Research and Intervention
