Antidepressant may slow Alzheimer’s disease

Antidepressants can reduce production of the main ingredient of Alzheimer’s brain plaques, according to new research at Washington University School of Medicine in St. Louis and the University of Pennsylvania. The plaques are highlighted in red in this image of a mouse’s brain.

New perspective needed for role of major Alzheimer’s gene

Scientists’ picture of how a gene strongly linked to Alzheimer’s disease harms the brain may have to be revised, researchers at the School of Medicine have found. Washington University’s David M. Holtzman, MD, says leading researchers recently agreed that targeting this gene is a promising approach for gaining a better understanding of and improving treatments for the disease.

Study in mice suggests sleep problems may be early sign of Alzheimer’s

Sleep disruptions may be among the earliest indicators of the start of Alzheimer’s disease, scientists at Washington University School of Medicine in St. Louis report this week in Science Translational Medicine. David M. Holtzman, MD, the Andrew B. and Gretchen P. Jones Professor and head of the Department of Neurology, is the study’s author.

Alzheimer’s plaques disrupt brain networks

Scientists studying the way Alzheimer’s disease takes root in the brain have identified important new similarities between a mouse model and human Alzheimer’s. Researchers at Washington University School of Medicine in St. Louis have shown that brain plaques in mice are associated with disruption of the ability of brain regions to network with each other.

Malfunctioning protein contributes to Alzheimer’s plaques

Scientists at Washington University School of Medicine in St. Louis have found that a protein made by a key Alzheimer’s gene slows the brain’s ability to get rid of amyloid beta, the main ingredient of the amyloid plaques that characterize the devastating illness.

Alzheimer’s patients can’t effectively clear sticky plaque component

Neurologists finally have an answer to one of the most important questions about Alzheimer’s disease: Do rising brain levels of a plaque-forming substance mean patients are making more of it or that they can no longer clear it from their brains as effectively? A new study by Randall Bateman, MD, assistant professor of neurology, shows clearance is impaired in Alzheimer’s patients.
