The Latest Discoveries in Alzheimer’s and Dementia Research
November 21, 2020

Over 120,000 people age 65+ in Washington state—and more than 5.8 million nationally—live with Alzheimer’s disease. Without effective treatment or cure, the impact of Alzheimer’s will continue to rise. This drives the Alzheimer’s Association’s investments in research to understand the basic biology underlying Alzheimer’s and other dementias.

Recently, Dr. Maria Carrillo, Chief Science Officer at the Association, gave a virtual presentation—“Advancing the Science: The Latest Discoveries in Alzheimer’s and Dementia Research”—through Town Hall Seattle.

“This is such a hopeful time,” said Carrillo. “Research is getting us the answers we are looking for, though we are confronting a very complex set of diseases under the umbrella of dementia.”

Carrillo provided an overview of the latest research advances in prevention, detection, diagnostics, and therapeutic interventions. Her presentation came on the heels of the Alzheimer’s Association International Conference® 2020, the largest and most influential international meeting dedicated to advancing dementia science. Following are highlights.

Early detection, diagnosis, and finding a cure
Biological markers, or biomarkers, help researchers measure change in the body and are accelerating the speed of research. Two biomarker hallmarks of Alzheimer’s disease are amyloid plaques and tau tangles. A promising blood test in development detects p-Tau217, the tau specific to Alzheimer’s, at a low cost and possibly up to 20 years before symptoms occur.
Biomarkers can assist with early detection and diagnosis. This in turn can help individuals prioritize their health, possibly delay or slow disease progression, plan for their future, and become eligible for a wider variety of clinical trials to help advance research.

Risk and lifestyle
While age, family history, and heredity are risk factors we can’t change, research reveals clues to other risk factors we may be able to modify, including lifestyle, cardiovascular health, physical activity, diet, sleep, social/cognitive engagement, education, and traumatic brain injury.
A two-year clinical trial called the U.S. POINTER study is currently underway. This study evaluates whether lifestyle interventions—specifically physical activity, cognitive and social stimulation, healthy diet, and health coaching—that simultaneously target many risk factors also protect cognitive function in older adults who are at increased risk for cognitive decline.

Drug trials and approvals
In 2020, the largest number of drugs in the Alzheimer’s clinical trials pipeline are treatments that prevent or slow down the loss of function. The developer of an anti-amyloid therapy to treat mild cognitive impairment (MCI) due to Alzheimer’s and mild Alzheimer’s is seeking FDA approval. Researchers reported a reduction in clinical decline, benefits on cognition and function, and a reduction of amyloid/tau biomarkers. FDA approval is anticipated March 2021.
Flu and pneumonia vaccination
New research presented at AAIC 2020 suggests flu and pneumonia vaccines may be associated with a lower risk of Alzheimer’s. One study found a single flu shot was associated with a 17 percent lower prevalence of Alzheimer’s, while another study reported that, for people between 65 and 75, a pneumonia vaccine reduced the risk of Alzheimer’s by 40 percent. More frequent flu and pneumonia vaccinations were associated with an even greater risk reduction.
“These new findings make an even stronger case for the potential of behavioral interventions throughout life to reduce risk of Alzheimer’s and other dementias,” said Carrillo.
