Dementia Matters

Though new blood-based biomarker tests have made it less expensive, less invasive and more accessible to diagnose Alzheimer’s disease, they can’t replace the diagnostic process as a whole. Dr. Eric Widera joins the podcast to discuss the importance of assessing function when making a dementia diagnosis, what functional change can look like and how this kind of assessment can be incorporated into primary care practice, as well as debate how Alzheimer’s disease blood tests should be used in primary care.

Guest: Eric Widera, MD, professor of medicine, clinician-educator, Division of Geriatrics, University of California San Francisco (UCSF), director, Chief of Geriatrics, Palliative and Extended Care, medical director, Hospice & Palliative Care Service, San Francisco VA Health Care System, co-founder, GeriPal podcast, co-founder, ePrognosis

In recent years, the U.S. Food and Drug Administration (FDA) has approved new biomarker tools for Alzheimer’s disease, including blood tests and tracers for brain scans. How are these tools used in research to help develop new Alzheimer’s treatments? Dr. Henrik Zetterberg returns to the podcast to discuss how blood tests, brain scans and other biomarker developments are transforming clinical trials and treatments for Alzheimer’s disease and other neurodegenerative conditions ahead of his upcoming Healthy Living with Mild Cognitive Impairment (MCI) event.

In recent years, public interest in brain health has increased. So how are Americans understanding brain health information and incorporating it into their own lives? This year, the Alzheimer’s Association released a special report focused on how people understand and support brain health throughout their lives, covering topics like how they perceive cognitive health, the importance of lifestyle behaviors and more. Dr. Heather Snyder from the Alzheimer’s Association joins us on the podcast to analyze this report and share her insights, as well as share updates from the 2026 Alzheimer’s Association International Conference (AAIC).

Twenty-five years ago, a single participant enrolled in what would become the Wisconsin Registry for Alzheimer's Prevention (WRAP), now one of the largest and longest-running studies of Alzheimer's risk in the world. To celebrate this milestone, we’re joined by Dr. Mark Sager, who co-founded WRAP, along with current multi-principal investigators Dr. Sterling Johnson and Dr. Jessica Caldwell, to discuss how the study has evolved, the discoveries that have reshaped our understanding of Alzheimer's prevention and what the next 25 years may hold for the field. 

Guests: Mark Sager, MD, founder, Wisconsin Alzheimer’s Institute (WAI), WRAP, Sterling Johnson, PhD, multi-principal investigator, WRAP, associate director, Wisconsin Alzheimer’s Disease Research Center, WAI, Jessica Caldwell, multi-principal investigator, WRAP, visiting associate professor, department of neurology, University of Wisconsin-Madison

Caring for those with dementia represents a major public health challenge, with caregivers, especially spouses, providing long-term, largely unpaid care. With caregiving stress linked to a decline in mental and physical health, it is crucial to understand the complex burden these care partners face in order to  support them. Dr. Donna de Levante Raphael joins the podcast to shed light on the effects of caregiving on the spousal caregiver and share possible interventions and programs to support their needs.
