10 Small Things Neurologists Wish You’d Do for Your Brain (Links to an external site)

Small tweaks to your daily routine can go a long way toward protecting your body’s control center and preventing cognitive decline down the road. In fact, scientists believe that as many as 45 percent of dementia cases could be delayed or prevented with help from some simple, sometimes surprising, changes in behavior.

Boosting brain’s waste removal system improves memory in old mice (Links to an external site)

Aging compromises the lymphatic vessels (green) in tissue called the meninges (blue) surrounding the brain, disabling waste drainage from the brain and impacting cognitive function. Researchers at WashU Medicine boosted lymphatic vessel integrity (bottom) in old mice and found improvements in their memory compared with old mice without rejuvenated lymphatic vessels (top).

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 […]

Researchers find a hint at how to delay Alzheimer’s symptoms. Now they have to prove it (Links to an external site)

The research led by Washington University in St. Louis involves families that pass down rare gene mutations almost guaranteeing they’ll develop symptoms at the same age their affected relatives did – information that helps scientists tell if treatments are having any effect. The new findings center on a subset of 22 participants who received amyloid-removing […]

Anti-amyloid drug shows signs of preventing Alzheimer’s dementia (Links to an external site)

Randall J. Bateman, MD, the Charles F. and Joanne Knight Distinguished Professor of Neurology at WashU Medicine, is the study director of an international clinical trial that finds an anti-amyloid drug can delay the onset of cognitive decline if given many years before symptoms of Alzheimer's disease arise. The participants in the study had inherited genetic variants that lead to early-onset Alzheimer's disease, and among those who received the drug the longest – an average of eight years – the treatment lowered the risk of developing symptoms from essentially 100% to about 50%, according to a preliminary analysis of the data.

An experimental drug appears to reduce the risk of Alzheimer’s-related dementia in people destined to develop the disease in their 30s, 40s or 50s, according to the results of a study led by the Knight Family Dominantly Inherited Alzheimer Network-Trials Unit (DIAN-TU), which is based at Washington University School of Medicine in St. Louis. The […]

Promising risk assessment results for new pediatric stroke treatment option

A recent safety surveillance paper published in Neurology reported that of eleven pediatric patients who were treated with tenecteplase for suspected stroke, there were no instances of intracranial bleeding or other safety concerns. This study is an important first step toward further research to establish the safety and efficacy of tenecteplase for treating pediatric stroke. […]

$4.5 million supports pathbreaking neuroimmunology research (Links to an external site)

A $4.5 million grant from the Carol and Gene Ludwig Family Foundation will support innovative projects led by WashU Medicine’s neuroimmunology experts, including (from left to right) David M. Holtzman, MD; Jonathan Kipnis, PhD; and Marco Colonna, MD, in addition to other faculty members through a seed grant program.

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 […]

Electrochemical field key to how dementia precursors ‘break bad’ (Links to an external site)

Protein accumulations do important work in the human body, but something can go wrong and proliferate in those aggregates, resulting in neurodegeneration and diseases such as Parkinson’s and Alzheimer’s. One such assembly, amyloid beta peptide, is synonymous with dementia, but researchers were not certain how these peptide assemblies “break bad” and what really causes them […]
