Addressing Cochrane’s Review on Amyloid-Targeting Treatments for Alzheimer’s Disease

Amyloid-targeting monoclonal antibody treatments have ushered in a new era of Alzheimer’s disease therapies after decades of research and clinical trials. A recent review published by Cochrane, a global, independent, non-profit network of researchers, professionals, patients and carers regarded as a gold standard for producing and promoting trusted, high-quality health information, has a different perspective on these therapies. The review found these treatments produce “little to no difference” in cognition and offer few benefits while increasing risks for adverse effects. Drs. Cynthia Carlsson, a clinical trialist, David Wolk, a clinician, and Henrik Zetterberg, a biomarker and disease biology expert, join the podcast to break down the review and their concerns, as well as highlight how this review could impact clinical care, research and public policy.

Holland, Sr., Professor in Alzheimer’s Disease, geriatrician, University of Wisconsin (UW) School of Medicine and Public Health; David Wolk, MD, director, Penn ADRC, co-director, Penn Memory Center, co-director, Penn Institute on Aging, professor of neurology, University of Pennsylvania Perelman School of Medicine; and Henrik Zetterberg, MD, PhD, professor of neurochemistry, University of Gothenburg, visiting professor, UW–Madison and University College London, Biomarker Core co-leader, Wisconsin ADRC

Study Finds COVID-19 Can Cause Build-up of Alzheimer’s-Related Proteins in Eyes and Brain

What do COVID-19 brain fog and ophthalmology have to do with Alzheimer’s disease? There may be more connections than one might think. Dr. Sean Miller is one of the scientists behind a recent study that used retinal tissue to investigate the links between COVID-19 infections and the build-up of amyloid and other indicators of Alzheimer’s disease in the central nervous system. Dr. Miller joins the podcast to discuss his research and its implications for COVID and dementia diagnosis and treatments in the future.

Harnessing the Power of Autophagy to Treat Alzheimer’s Disease

The Puglielli lab at the University of Wisconsin School of Medicine and Public Health has found a way to manipulate autophagy — a process where cells clean out damaged materials — to rid the brain of toxic proteins like amyloid and tau. Researchers hope to use the power of this process to develop future treatments for Alzheimer’s disease and other diseases of aging. Luigi Puglielli joins the podcast to discuss his team’s research over the past 15 years, why the scientific process can take years to turn ideas into possible treatments, and how he hopes this research can be used in the future.

Safely Disclosing Amyloid Results with Alzheimer’s Disease Research Participants

Dr. Lindsay Clark’s new study will evaluate the psychological consequences of disclosing amyloid test results to cognitively unimpaired adults. Dr. Clark joins the podcast to define amyloid accumulation and discuss how her study will examine the process of revealing amyloid results to research participants in Alzheimer’s disease research studies.

It Takes Two to Tango: The Importance of Amyloid and Tau in Cognitive Decline

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.
