Boosting brain’s waste removal system improves memory in old mice

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer’s disease and Parkinson’s disease, among others. Now, researchers at Washington University School of Medicine in St. Louis report they have found a way around that problem by […]

$4.5 million supports pathbreaking neuroimmunology research

Washington University School of Medicine in St. Louis has received a three-year $4.5 million grant from the Carol and Gene Ludwig Family Foundation, aimed at advancing research on neuroimmunology and neurodegeneration with the ultimate goal of developing new treatments for Alzheimer’s disease. Administered by WashU Medicine’s Brain Immunology & Glia (BIG) Center, the Carol and Gene […]

The brain has a waste removal system and scientists are figuring out how it works

The brain needs to flush out waste products to stay healthy and fend off conditions like Alzheimer’s disease. Scientists are beginning to understand how the the brain’s waste removal system works. [Transcript] A MARTÍNEZ, HOST: Turns out the brain needs regular cleaning. Otherwise, it gets clogged up with waste products, including some associated with diseases […]

Neurons help flush waste out of brain during sleep

There lies a paradox in sleep. Its apparent tranquility juxtaposes with the brain’s bustling activity. The night is still, but the brain is far from dormant. During sleep, brain cells produce bursts of electrical pulses that cumulate into rhythmic waves — a sign of heightened brain cell function. But why is the brain active when we […]
