The Issues: Alzheimer’s and Dementia (Links to an external site)
On this episode of The Issues, host Sarah Bernard and her guests (including Dr. Suzanne E. Schindler) speak about Alzheimer’s, dementia, how to care for loved ones with the disease, how to help prevent and delay Alzheimer’s, and new tests for and research about the disease.
Rejuvenated immune cells can improve clearance of toxic waste from brain (Links to an external site)
Researchers at Washington University School of Medicine in St. Louis have found an innovative way to improve waste clearance from the brain, and thereby possibly treat or even prevent neurodegenerative conditions. They showed that immune cells surrounding the brain influence how efficiently waste is swept out of the brain, and that such immune cells are impaired in old mice, and in people and mice with Alzheimer’s disease. Further, they found that treating old mice with an immune-stimulating compound rejuvenates immune cells and improves waste clearance from the brain.
What causes Alzheimer’s? Study puts leading theory to ‘ultimate test’ (Links to an external site)
Scientists are launching a study designed to make or break the hypothesis that Alzheimer’s is caused by a sticky substance called beta-amyloid. The study will give an experimental anti-amyloid drug to people as young as 18 who have gene mutations that often cause Alzheimer’s to appear in their 30s or 40s.
$9 million to fund study of ‘jumping genes’ in Alzheimer’s (Links to an external site)
A five-year, $9 million grant from the National Institute on Aging of the National Institutes of Health (NIH) will fund research led by several investigators at Washington University School of Medicine in St. Louis and at the University of Texas at San Antonio to answer that question.
Better Cognitive Predictor in People at High Risk of Alzheimer’s Disease (Links to an external site)
The Alzheimer’s disease (AD) drug lecanemab’s recent success in Biogen’s Phase III clinical trials might have more to do with its effect in increasing levels of soluble amyloid-beta than in decreasing amyloid plaques in the brain, the findings of a new study published in the Journal of Alzheimer’s Disease on October 4, 2022, suggests.
