Our guests, Dr. Rebecca Koscik and Dr. Tobey Betthauser, are researchers investigating the trajectory of amyloid and tau proteins over time and the significance of amyloid chronicity. Koscik and Betthauser discuss their two recent publications on the topic and how amyloid PET scans have helped scientists better understand the early brain changes associated with Alzheimer’s disease. Guests: Rebecca Koscik, PhD, senior scientist, Tobey Betthauser, PhD, postdoctoral fellow, University of Wisconsin-Madison

When it comes to dementia diagnoses, the earlier, the better, but why is it difficult to detect dementia in its early stages? Moreover, what strategies can be used to improve dementia detection? Dr. Josh Chodosh joins the podcast to answer these questions and discuss how public health initiatives could improve dementia diagnoses. He also talks about his work with the Building Our Largest Dementia (BOLD) Center, a public health center focused on early detection and ending the stigma around dementia.
Guest: Joshua Chodosh, MD, director, division of geriatric medicine and palliative care, Michael L. Freedman professor of geriatric research, Grossman School of Medicine, New York University, staff physician, VA Harbor Healthcare System

Be BOLD: Detecting Dementia Early through Public Health Initiatives

Picture this: you are supporting someone experiencing memory changes as a clinician, support person or care partner while they go through the memory clinic process. How do you navigate the challenging conversations surrounding symptoms, diagnoses, care plans and more that come up? Dr. Toby Campbell joins the podcast to discuss the importance of shared decision-making and share strategies for clinicians, care partners and loved ones to help navigate these important conversations with respect and empathy.

Let’s Talk: Navigating Family Conversations about Dementia through Shared Decision-Making

Advances in Alzheimer’s disease clinical trials are accelerating rapidly, leading to new insights and disease-modifying therapies, but how does the field continue bolstering that momentum? For Dr. Rema Raman, it’s through improving inclusivity and training for early-career researchers. Recorded at the 2024 Alzheimer’s Disease & Related Dementias Research Day, Dr. Raman joins the podcast to discuss her work in research recruitment and retention, the importance of training the next generation of clinical trialists in dementia research with the IMPACT-AD program and more from her featured presentation.

Making an IMPACT: Advancing Alzheimer’s Disease Clinical Trials Through Workforce Development and Inclusivity

What do you do if you have a family history of dementia and are experiencing symptoms, but can’t get a diagnosis? Dr. Sara Langer has dealt with just that. In the latest episode of our Voices of Research Participants series, Dr. Langer shares the obstacles she endured to receive her diagnosis of Lewy body dementia (LBD), how her background as a neurologist influenced her search for clinical care and how she turned to dementia research to find answers. She also discusses ways that the field of dementia research could improve to support those with other forms of dementia outside of Alzheimer’s disease.

Living with Lewy Body: A Neurologist’s Journey Through Research and Dementia Care

The brain is the most complex part of the human body, controlling thought, memory, emotion, motor skills, sensory input and all the processes that regulate our bodies. How exactly does it work, and how are clinicians able to determine whether brain changes are a result of normal aging, Alzheimer’s disease, or something else? Dr. Victoria Williams joins the podcast to explain important concepts in neuropsychology, from the difference between cognition and intelligence to how memories are made, and discuss how cognitive tests work in memory clinics.
