Welders are in danger of developing symptoms similar to those of Parkinson’s disease, according to a new study that suggests exposure to fumes containing manganese makes things worse. Welding has been linked in previous research to a higher risk for parkinsonism. The term refers to a group of disorders that causes movement problems that mimic […]

Researchers are studying families for clues to how Alzheimer’s develops

Rosemary Navarro was living in Mexico when her brother called from California. Something wasn’t right with their mom, then in her early 40s. She was having trouble paying bills and keeping jobs as a food preparer in convalescent homes. Navarro, then 22, moved back to the U.S. with her two young children. Before long, Navarro […]

Some elderly with Alzheimer’s brain plaques stay sharp

In a discovery that challenges conventional thinking, researchers report that several people over the age of 90 had excellent memory even though their brains showed signs that they had Alzheimer’s disease. The meaning of the findings isn’t entirely clear. The elderly people, whose brains were studied after their deaths, may have been in the early […]

At Age 8, DIAN Is Churning Out Data and Growing into a Movement

One February 25, 2015, Lori DeMoe McIntyre died of Alzheimer’s disease at age 56, after participating in DIAN research for nearly eight years. Her daughter Jessica McIntyre memorialized her mom with a large tattoo of Lori’s amyloid PIB PET scan. The younger McIntyre and one of her sisters participate in DIAN and DIAN-TU.

Part 1 of a five-part series. At age 8, DIAN has grown up. In 2008, when the Dominantly Inherited Alzheimer’s Network formally began to study autosomal-dominant AD, the notion of assembling globally dispersed families afflicted with this rare form of AD into a standing research platform seemed radical to observers. In theory, the idea of […]

Cirrito receives MetLife award for Alzheimer’s research

John Cirrito, PhD

Researcher is known for developing a way to measure levels of amyloid beta in brain John Cirrito, PhD, has been honored by the MetLife Foundation for his work measuring levels in the brain of amyloid beta, a protein linked to the neural degeneration of Alzheimer’s disease. John Cirrito, PhD, an associate professor of neurology at […]

$4 million grant expands major study to find Alzheimer’s prevention treatments

Investigators will accelerate drug testing, develop new diagnostic measures. Washington University School of Medicine in St. Louis has received a $4.3 million award from the Alzheimer’s Association to expand a major international clinical trial evaluating whether drugs can prevent Alzheimer’s disease in patients genetically predisposed to develop the devastating disease at a young age. The […]

New insight into role of amyloid beta in Alzheimer’s disease

A new technique for measuring levels in the brain of amyloid beta, a key protein associated with Alzheimer’s disease, would help scientists design treatments to limit its accumulation.

New Alzheimer’s disease research details a technique that speedily measures levels in the brain of a damaging protein fragment, and insight into why mutations in a specific gene increase the risk of developing the disease. Both studies, from researchers at Washington University School of Medicine in St. Louis, are available online in the Journal of […]
