Talking about Tau: The Role of Tau PET Scans in Alzheimer’s Research and Care

Posted on

Early detection is a top priority in the field of Alzheimer’s research, and one indicator of Alzheimer’s disease is the buildup of tau in the brain. What is tau, though? How can we detect this protein, and what can it tell us about a person’s symptoms or disease progression? Dr. Gil Rabinovici, a leader in the field of brain imaging, joins Dementia Matters this week for an in-depth discussion on the role of tau PET scans in Alzheimer’s disease detection, research and clinical care.

Guest: Gil Rabinovici, MD, professor, Department of Neurology, University of California San Francisco (UCSF), director, UCSF Alzheimer’s Disease Research Center, study chair, Imaging Dementia-Evidence for Amyloid Scanning (IDEAS) and New IDEAS studies, co-principal investigator, Alzheimer’s Network for Treatment and Diagnostics (ALZ-NET), Longitudinal Evaluation of Alzheimer’s Disease Study (LEADS)

National Efforts To Standardize Brain Scan Data For More Accurate Alzheimer’s Risk Predictions

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.

Go with the (4D) Flow: Neuroimaging Technology Used to Study Overlap of Cerebrovascular Disease and Alzheimer’s

Posted on

A recent study from Alzheimer’s disease researchers at the University of Wisconsin–Madison used neuroimaging technology called 4D Flow MRI to study the relationship between blood vessel disease and Alzheimer’s disease. Published in December 2021, the study found that people with Alzheimer’s disease symptoms had stiffer blood vessels in their brains, which could lead to inflammation and a buildup of Alzheimer’s biomarkers like amyloid and tau proteins. Lead researcher Leonardo Rivera-Rivera joins the podcast to discuss his findings, the developments made with new 4D Flow MRI scans, and how these developments could impact future Alzheimer’s disease research and clinical practices.

Alzheimer’s Disease Risk Is High in People with Down Syndrome

Posted on

With the dramatic increase in life expectancy among people with Down syndrome over recent decades, it has been observed they develop Alzheimer’s disease at a much younger age and at a much higher incidence than the general population. Our guest, an expert on brain imaging and neurodegeneration, discusses the theories behind this relationship and the similarities and differences in how Alzheimer’s disease progresses in the Down syndrome and general populations.
