On July 6, 2023, the U.S. Food and Drug Administration (FDA) granted full approval for the Alzheimer’s disease drug Leqembi (lecanemab-irmb), the first medicine shown to delay the course of the disease. Having gone through a rigorous approval process, the medication exemplifies a critical advancement in the ongoing battle to treat Alzheimer’s disease. Having already prescribed the treatment to real-life patients, Dr. Robert Przybelski joins the podcast to discuss his experience prescribing and administering lecanemab, what clinicians and patients should discuss when considering these treatments, and what is needed to integrate these treatments into the healthcare system.

The field of biomarkers is advancing quickly, allowing preclinical Alzheimer’s disease to be identified earlier and earlier in a person’s life. As individuals learn they are at risk for Alzheimer’s years or even decades before experiencing cognitive decline, what does this mean for them and for society as a whole? Drs. Emily Largent and Claire Erickson join the podcast to discuss ten key areas, such as healthcare, insurance, and direct-to-consumer testing, that should be addressed to support those at risk for cognitive decline and broader U.S. society as biomarker testing and disclosures become more prominent.

Though brain and cognitive changes are typically diagnosed as one form of dementia, recent studies have shown that mixed dementia is more common than previously thought. Mixed dementia, also known as Multiple-etiology dementia, is a condition where brain changes are caused by more than one neurological disease, such as Alzheimer’s disease, Lewy body dementia (LBD), or frontotemporal dementia. Dr. Roderick Corriveau joins the podcast to discuss what is known about mixed dementia and how the field of studying neurological diseases is advancing to diagnose and treat this condition.

Though several validated biomarkers are studied and used in Alzheimer’s disease research, most research participants don’t have the opportunity to learn their biomarker results afterward, even if they have cognitive impairment. Drs. Jason Karlawish and Josh Grill join the podcast to discuss the debate over sharing biomarker results with research participants, how these powerful disclosures can be made ethically, and why it's as important for the field to study biomarker disclosures as it is to study the biomarkers themselves.

Dementia Matters Special Series: The National Strategy for Alzheimer's Disease Data and Research Part 4

Brain imaging is a key tool in Alzheimer’s disease research and diagnoses, allowing scientists to see changes in the brain years, even decades, before an individual experiences symptoms of dementia. The data these images provide researchers with is incredibly useful, leading the National Alzheimer’s Coordinating Center to take up numerous efforts to standardize, unify and share this type of data across the Alzheimer’s Disease Research Centers. Dr. Beth Mormino joins the podcast to discuss the NIA’s SCAN initiative, the new “legacy” data set, and the importance of standardizing MRI and PET scan procedures to predict brain trajectories better.
