Under normal circumstances, tau protein is part of the brain’s infrastructure, important for stabilizing neurons into their proper shapes. But sometimes tau gets knotted up into tangles and turns toxic, injuring brain tissue and causing tauopathies, a group of brain diseases characterized by problems with learning, memory and movement. Alzheimer’s disease is the most common […]
Nearly every person with Down syndrome eventually develops Alzheimer’s disease, yet people with the syndrome routinely are excluded from Alzheimer’s clinical trials, as the cognitive assessment tools designed for the general population often are inappropriate for people with developmental disabilities. Consequently, nobody knows whether the new Alzheimer’s therapeutics hitting the market will work for people […]
Patients who live in less affluent neighborhoods and those from underrepresented racial or ethnic groups are less likely than others to receive specialized care for dementia, including Alzheimer’s disease, a new study from Washington University School of Medicine in St. Louis indicates. Further, the research shows that Black people are more likely than white people […]
Two pathologies drive the progression of Alzheimer’s disease. Early on, amyloid beta plaques lead the way, but around the time cognitive symptoms arise, tau tangles take over as the driving force and cognition steadily declines. Tracking the course of the disease in individual patients has been challenging because there’s been no easy way to measure […]
The COVID-19 pandemic will forever be associated with unprecedented lockdowns and inconveniences such as wearing masks in public. And that’s largely because health experts had no idea exactly where the SARS-CoV-2 virus was lurking, and how risky crowded settings such as workplaces, classrooms, and public transportation were.
Now that the emergency phase of the COVID-19 pandemic has ended, scientists are looking at ways to surveil indoor environments in real time for viruses. By combining recent advances in aerosol sampling technology and an ultrasensitive biosensing technique, researchers at Washington University in St. Louis have created a real-time monitor that can detect any of […]
ST. LOUIS, Mo. (Ivanhoe Newswire) – Imagine your toddler learning to walk and talk and then all of a sudden, your child stops and starts regressing inside of themselves. That’s what happens to children born with a rare genetic neurological disorder called Rett syndrome. It steals a child’s ability to talk and use any sort […]
It’s not easy to distinguish between the dozens of subtypes of limb girdle muscular dystrophy — a rare, genetic muscle disease characterized by weakness in the hips and shoulders that causes difficulty walking and lifting the arms. Until now, determining the subtype has not been critical in caring for patients, because no specific treatments have […]
When it comes to a disease as complex as Alzheimer’s, scientists have found a number of factors that can contribute to your risk, from genes to circulatory issues, inflammation, and lifestyle behaviors. In a new study published in Science Translational Medicine, researchers from Washington University in St. Louis report on another possible factor: the types of bacteria living […]
People in the earliest stage of Alzheimer’s disease — after brain changes have begun but before cognitive symptoms become apparent — harbor an assortment of bacteria in their intestines that differs from the gut bacteria of healthy people, according to a study by researchers at Washington University School of Medicine in St. Louis.
