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 […]
Physician-scientists split their time between caring for patients and unraveling biological mysteries. This dual expertise can yield the kind of insights that power groundbreaking medical advances and advance human health. Yet only a small and shrinking fraction of physicians pursue joint careers in the clinic and the lab. Researchers at Washington University School of Medicine […]
The Food and Drug Administration (FDA) recently gave full approval to Leqembi (lecanemab) for patients in the early stages of Alzheimer’s disease. Physicians and researchers at Washington University School of Medicine’s Charles F. and Joanne Knight Alzheimer Disease Research Center (Knight ADRC) in St. Louis were involved in the clinical trials evaluating Leqembi, in which they enrolled […]
Scientists have completed a deep analysis of the proteins driving cancer across multiple tumor types, information that can’t be assessed by genome sequencing alone. Understanding how proteins operate in cancer cells raises the prospect of new therapies that block key proteins that drive cancer growth, or therapies that trigger immune responses to abnormal proteins created […]
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 […]
A new study from Washington University School of Medicine in St. Louis suggests that growing up in poverty may influence the wiring of a child’s brain. The study, published June 27 in JAMA Network Open, indicates a link between both neighborhood and household poverty and the brain’s white matter tracts, which allow for communication between […]
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 […]
Children with specific psychiatric symptoms, such as anxiety, may struggle to understand emotional cues when people around them are happy, sad or angry, and that lack of understanding can make it difficult to respond appropriately in social situations. Studying brain scans from hundreds of children ages 5 to 15, researchers at Washington University School of […]
Figuring out what’s going on inside people’s heads typically requires huge, expensive equipment and volunteers willing to spend hours performing repetitive tasks while lying inside a narrow metal tube. Researchers at Washington University in St. Louis are working on an alternative. They are developing a cap that can be worn while moving around normally that […]
The Human Genome Project, funded by the National Institutes of Health (NIH), ended in April 2003 and produced a human genome sequence made up of a patchwork of data from a small number of individuals. This lack of diversity limited its usefulness as a research tool for understanding human health and disease. Now, researchers have […]
Strategies to treat pain without triggering dangerous side effects such as euphoria and addiction have proven elusive. For decades, scientists have attempted to develop drugs that selectively activate one type of opioid receptor to treat pain while not activating another type of opioid receptor linked to addiction. Unfortunately, those compounds can cause a different unwanted […]
Dangerous bacterial bloodstream infections in preemies may originate from the infants’ gut microbiomes, according to researchers at Washington University School of Medicine in St. Louis. Such infections are of substantial concern, as about half of infants who are extremely preterm or have very low birth weights experience at least one episode of the life-threatening infection […]
Women are about twice as likely as men to be diagnosed with Alzheimer’s disease. Some of that is age; in the U.S., women outlive men by five to six years, and advanced age is the strongest risk factor for Alzheimer’s. But there’s more to it than that, so Alzheimer’s researchers continue to look for other […]
Calm body, calm mind, say the practitioners of mindfulness. A new study by researchers at Washington University School of Medicine in St. Louis indicates that the idea that the body and mind are inextricably intertwined is more than just an abstraction. The study shows that parts of the brain area that control movement are plugged […]
Researchers in child psychiatry and pediatric neurology at Washington University School of Medicine in St. Louis have been named recipients of a prestigious MERIT award from the National Institute of Mental Health of the National Institutes of Health (NIH) to support their research focused on preterm babies’ brains as the children age. The MERIT (Method […]
Nearly two dozen experimental therapies targeting the immune system are in clinical trials for Alzheimer’s disease, a reflection of the growing recognition that immune processes play a key role in driving the brain damage that leads to confusion, memory loss and other debilitating symptoms. Many of the immunity-focused Alzheimer’s drugs under development are aimed at […]
For older adults with clinical depression that has not responded to standard treatments, adding the drug aripiprazole (brand name Abilify) to an antidepressant they’re already taking is more effective than switching from one antidepressant to another, according to a new multicenter study led by Washington University School of Medicine in St. Louis. Aripiprazole originally was […]
The brain health of millions of malnourished children stands to benefit following changes to global guidelines for the formulation of ready-to-eat therapeutic food — the standard treatment for severe malnutrition in developing countries. Results of a major clinical trial in Africa led by Mark Manary, MD, a professor of pediatrics at Washington University School of Medicine in […]
The brain floats in a sea of fluid that cushions it against injury, supplies it with nutrients and carries away waste. Disruptions to the normal ebb and flow of the fluid have been linked to neurological conditions including Alzheimer’s disease and hydrocephalus, a disorder involving excess fluid around the brain. Researchers at Washington University School […]
A generous $15 million commitment from Philip and Sima Needleman, longtime benefactors of Washington University in St. Louis, will enable WashU to leverage its expertise in biomedical discovery to boost drug development. The Needleman Program for Innovation and Commercialization (NPIC) will bridge the gap between the identification of promising therapeutic targets in the laboratory and […]
Patients with glioblastoma, a devastating brain cancer, receive treatment that frequently leads to the unfortunate side effect of low white blood cell counts that lasts six months to a year. The low numbers of white blood cells are associated with shorter survival — but the specific reason for the prolonged drop in white blood cells […]
A growing pile of evidence indicates that the tens of trillions of microbes that normally live in our intestines — the so-called gut microbiome — have far-reaching effects on how our bodies function. Members of this microbial community produce vitamins, help us digest food, prevent the overgrowth of harmful bacteria and regulate the immune system, […]
Researchers at Washington University School of Medicine in St. Louis have received a grant from the Centers for Disease Control and Prevention (CDC) totaling $12.5 million to investigate the real-world effectiveness of influenza and COVID-19 vaccines and the immune response to infection and vaccination against these two illnesses. Unlike a strictly controlled clinical trial, this […]
Washington University School of Medicine in St. Louis and the pharmaceutical company Eisai Co. Ltd., headquartered in Japan, have formed a research collaboration aimed at developing new treatments for Alzheimer’s disease, Parkinson’s disease and other neurodegenerative conditions. The two organizations previously have partnered on Alzheimer’s clinical trials, and the new alliance combines their complementary efforts […]
A large study that focused on whether exercise and mindfulness training could boost cognitive function in older adults found no such improvement following either intervention. Researchers at Washington University School of Medicine in St. Louis and the University of California, San Diego, studied the cognitive effects of exercise, mindfulness training or both for up to […]
The cancer therapy known as CAR-T has revolutionized treatment of some blood cancers since it was introduced in 2017. The therapy uses genetically altered immune cells to home in on cancer cells and destroy them. Now, studying mice with an autoimmune disease similar to multiple sclerosis (MS), researchers at Washington University School of Medicine in […]
Zooming in on a single disease and studying it intensely is often the most productive route to finding treatments. But there’s no easy way to distinguish among people living with any of the primary tauopathies — a group of rare brain diseases marked by rapidly worsening problems with thinking and movement — because the symptoms […]
Alzheimer’s, Parkinson’s and many other neurodegenerative diseases are marked by damaging clusters of proteins in the brain. Scientists have expended enormous effort searching for ways to treat such conditions by clearing these toxic clusters but have had limited success. Now, researchers at Washington University School of Medicine in St. Louis have found an innovative way […]
Memory loss is often the first sign of Alzheimer’s disease, followed by confusion and difficulty thinking. These symptoms reflect the typical pattern of worsening damage to brain tissues. Toxic clusters of proteins first concentrate in the temporal lobes of the brain — the memory area — before spreading to parts of the brain important for […]
Several studies on COVID-19 have revealed gaping disparities in the U.S. that negatively affect the health of people who aren’t white, especially nonwhite women. A deep dive from researchers at Washington University School of Medicine in St. Louis and the university’s Brown School shows that in St. Louis County, Black women suffered at disproportionately higher […]
Huntington’s disease, a fatal, inherited neurodegenerative condition, is caused by a genetic error present at birth, though its symptoms often don’t begin until middle adulthood. Scientists at Washington University School of Medicine in St. Louis have been trying to understand how the aging process triggers the onset of symptoms, with the expectation that such knowledge […]
Two new studies from Washington University School of Medicine in St. Louis support development of a broadly applicable treatment for neurodegenerative diseases that targets a molecule that serves as the central executioner in the death of axons, the wiring of the nervous system. Blocking this molecular executioner prevents axon loss, which has been implicated in […]
Researchers at Washington University School of Medicine in St. Louis have identified a pathway in the brains of mice that is activated when the animals see other mice scratching. The researchers previously reported that the urge to scratch an itch after seeing other mice scratching is hardwired in the brain. Now they have found that […]
If you’ve had COVID-19, it may still be messing with your brain. Those who have been infected with the virus are at increased risk of developing a range of neurological conditions in the first year after the infection, new research shows. Such complications include strokes, cognitive and memory problems, depression, anxiety and migraine headaches, according […]
Scientists at Washington University School of Medicine in St. Louis are joining a national network to map the intricacies of the brain, with a goal of deepening knowledge of how the brain works and generating new insights into how the brain functions in healthy people — and how it malfunctions in Alzheimer’s, schizophrenia, autism and […]
An investigational drug developed to treat a rare, inherited form of amyotrophic lateral sclerosis (ALS) reduced molecular signs of the fatal, paralyzing disease and curbed neurodegeneration — but at the six-month mark, the drug did not improve motor control and muscle strength, according to results from a phase 3 clinical trial led by researchers at […]
Imagine if one day in the future, doctors could diagnose throat cancer, Alzheimer’s, depression or other diseases based on the sound of a patient’s voice. To help make that a reality, Washington University School of Medicine in St. Louis is joining the National Institutes of Health (NIH) Bridge2AI program, an estimated $130 million initiative intended […]
Cell-based immunotherapy called CAR-T cell therapy has revolutionized the treatment of several cancers. The treatment uses genetically modified T cells to target and attack certain types of leukemia and lymphoma. While it can eliminate cancer in some patients who would otherwise succumb to the disease, it also comes with the risk of a range of […]
A new center established at Washington University School of Medicine in St. Louis aims to accelerate research into biomarkers of neurodegenerative conditions such as Huntington’s and Parkinson’s diseases, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS) and the so-called tauopathies, a group that includes Alzheimer’s disease along with rarer diseases such as frontotemporal dementia, corticobasal syndrome […]
When something goes wrong in mitochondria, the tiny organelles that power cells, it can cause a bewildering variety of symptoms such as poor growth, fatigue and weakness, seizures, developmental and cognitive disabilities, and vision problems. The culprit could be a defect in any of the 1,300 or so proteins that make up mitochondria, but scientists […]
Fragile X syndrome, the leading inherited cause of intellectual disability, is due to a genetic mutation that largely eliminates the fragile X protein, a critical element of normal brain development and function. The fragile X protein modulates neuronal functions, including neurons within the so-called GABAergic system that regulates the activity of neural circuits. The protein’s […]
Less than half of Americans who received treatment for opioid use disorder over a five-year period were offered a potentially lifesaving medication, researchers at Washington University School of Medicine in St. Louis and Saint Louis University have found. And treatment with the medication was even more rare for those with what’s known as polysubstance use […]
About 18 million children under age 5 suffer from severe acute malnutrition, and over 3 million children die from it each year. Treatment with high-calorie supplemental foods and antibiotics can prevent deaths, but these interventions often have limited impact on the long-term effects of severe acute malnutrition, such as persistent stunted growth, disrupted immune function […]
The TV sitcom grandpa character who always seems to fall asleep at unfortunate moments is so common it’s almost a cliché. But daytime napping and disjointed sleep at night aren’t normal parts of aging. Sleep disturbances can be an early sign of a neurodegenerative condition, and they may be treatable. Researchers at Washington University School […]
A study in mice — led by researchers at Washington University School of Medicine in St. Louis — shows that a new class of compounds the scientists developed can improve multiple aspects of metabolic syndrome. An increasingly common group of conditions that often occur together, metabolic syndrome includes type 2 diabetes, high cholesterol, fat buildup […]
After two years of wearing layers of protective equipment on crowded hospital floors and working shift after shift with COVID-19 patients, many front-line health-care workers are suffering burnout, anxiety, depression and other difficulties. Consequently, many have left the field or started to question whether to remain. Reducing burnout and promoting mental health and wellness among […]
Washington University School of Medicine in St. Louis is part of a major international study aimed at identifying causes and effects of the early stages of schizophrenia in young people, with the goal of improving early diagnosis and treatment. The mental illness is characterized by alterations in thoughts, feelings and behaviors, which may include psychosis, […]
The burden of Alzheimer’s disease doesn’t fall on all communities equally. Black Americans face about double the risk of developing the devastating neurodegenerative disease than non-Hispanic white Americans do. The factors that place Black people at elevated risk remain poorly understood, partly because Black people historically and systematically have been underrepresented in Alzheimer’s studies. Without […]
Tracking medications provided to over a half million U.S. women, researchers at Washington University School of Medicine in St. Louis have found that many commonly prescribed older antipsychotic medications, and some newer ones, are associated with a significant increase in risk of breast cancer. Antipsychotics are prescribed for a broad range of conditions, including depression, […]
