So much has happened in the world to cause people to think deeper about their mental well-being and resiliency during difficult times. More than 50% of the population has struggled with a mental health issue at some point in their lives. They can be as disabling as physical conditions and are among the leading causes […]
Negative emotional states and physical pain are intimately connected. Numerous people who suffer from chronic, persistent pain also deal with negative emotions and loss of motivation. Some even become clinically depressed eventually, and doctors sometimes prescribe antidepressants to treat chronic pain, even though the pathways that link pain and mood are poorly understood. Now, studying […]
For humans and animals, many aspects of normal behavior and physiology rely on the proper functioning of the body’s circadian clocks. Here’s how it’s supposed to work: Your brain sends signals to your body to release different hormones at certain times of the day. For example, you get a boost of the hormone cortisol — nature’s […]
Washington University School of Medicine in St. Louis has received a $7 million grant from the National Institutes of Health (NIH) to help lead national efforts to investigate how variations in the human genome sequence affect how the genome functions.

Alphaviruses — mosquito-borne viruses that can trigger brain infections and arthritis — may have met their match. Researchers at Washington University School of Medicine in St. Louis have identified two antibodies that protect animals from disease caused by alphaviruses. The antibodies worked for every alphavirus tested, meaning they potentially could form the basis of treatments […]
Should doctors take particular care to talk to patients about the potential dangers of COVID-19 if those patients have a problematic relationship with pot? New research from Washington University in St. Louis suggests perhaps they should. Diabetes, obesity and a history of smoking cigarettes are all considered risk factors for poorer COVID-19 outcomes. Warnings and […]
Children in poverty are more likely to have cognitive and behavioral difficulties than their better-off peers. Plenty of past research has looked into the physical effects of childhood poverty, or documented mental health disparities between socioeconomic classes. But Deanna Barch, chair and professor in the Department of Psychological & Brain Sciences in Arts & Sciences at […]
More than 50,000 surgical patients undergo general anesthesia every day in the United States, but clinicians and scientists lack evidence indicating which types of anesthesia drugs result in the best outcomes for patients.

Medulloblastoma is a rare but devastating childhood brain cancer. This cancer can spread through the spinal fluid and be deposited elsewhere in the brain or spine. Radiation therapy to the whole brain and spine followed by an extra radiation dose to the back of the brain prevents this spread and has been the standard of […]
Dozens of commonly used drugs, including antibiotics, anti-nausea and anticancer medications, have a potential side effect of lengthening the electrical event that triggers contraction, creating an irregular heartbeat, or cardiac arrhythmia called acquired Long QT syndrome. While safe in their current dosages, some of these drugs may have a more therapeutic benefit at higher doses, […]
Some 16 million Americans are believed to have alcohol use disorder, and an estimated 93,000 people in the U.S. die from alcohol-related causes each year. Both of those numbers are expected to grow as a result of heavier drinking during the COVID-19 pandemic. Yet, in a new study involving data from more than 200,000 people […]
Despite decades of research and investment, the genetic underpinnings of Alzheimer’s disease are still largely unknown, stymieing efforts at drug development and early diagnosis. To change that, a new grant will support the first comprehensive study to use whole genome sequencing to address critical gaps in knowledge about the disease. The $10.7 million, five-year project […]
More than 20 years after the launch of a landmark clinical trial, follow-up examinations and analyses found that not all patients with elevated eye pressure need pressure-lowering treatment to prevent vision loss from glaucoma. When the study was launched, it was universally accepted that all patients with elevated eye pressure should be given medication to […]
