WSU scientist studies link between poor sleep and PTSD

At any given time, an estimated 7.7 million American adults suffer from post-traumatic stress disorder (PTSD), a psychiatric condition that occurs in people who have experienced or witnessed a traumatic event. Though PTSD can affect anyone who lives through trauma, it is especially common among military veterans returning from combat zones.

The effects of PTSD can be debilitating. It’s one reason why neuroscientist Willie Vanderheyden—an assistant research professor in the WSU Elson S. Floyd College of Medicine—has set out to better understand the condition and its ties to one of his other research interests: sleep.

“Up to 90 percent of people who have experienced trauma suffer from some type of sleep disturbance, whether it’s fragmented sleep, difficulty falling or staying asleep, or nightmares,” Vanderheyden said.

These sleep disturbances may be the result of PTSD, but Vanderheyden says it’s also possible that they are part of what is causing PTSD. » More …

Competition breaks research down into bite-sized chunks

Science is usually a serious matter, but there were plenty of laughs last week at the fourth annual Science Bites event held at WSU Spokane. The science communications competition featured ten graduate and professional students from the College of Pharmacy and Pharmaceutical Sciences and the Elson S. Floyd College of Medicine, who rose to the challenge of providing a compelling description of their research in no more than three minutes.

Participants could use one static PowerPoint slide and were expected to use language that could be understood by non-specialists. Facing a panel of judges, they pulled out all the stops, using a variety of laugh-inducing metaphors and anecdotes in their quest for top honors.

Prizes—including $200 toward travel expenses to attend the Science Talk ’19 conference in Portland—went to the top three competitors, all of whom are PhD in pharmaceutical sciences candidates working in different research labs.

Research: New study reveals how shift work disrupts metabolism

Study author Elena Skornyakov loads a blood sample into the cold centrifuge at the sleep laboratory at WSU Health Sciences Spokane

Working night shifts or other nonstandard work schedules increases your risk of becoming obese and developing diabetes and other metabolic disorders, which ultimately also raises your risk of heart disease, stroke and cancer.

Exactly why this happens has been unclear, but a new study conducted at Washington State University has brought scientists closer to finding the answer. » More …

Meet a Scientist: Dr. Lucia Peixoto’s Work Narrows the Search for Autism Risk Factors

A landmark study by scientists at WSU and elsewhere has brought focus to the search for genetic links to autism spectrum disorder, which affects an estimated 2 million Americans. Published in the Jan. 16 issue of Science Signaling, the study identifies more than 2,000 areas of DNA that are active when mice learn a new task and are strongly associated with autism. Taking a closer look at one of those areas, the researchers found a genetic mutation that is associated with increased risk of developing autism.

First Translational Medicine Symposium Showcases Progress, Challenges in Dealing with Brain Diseases

Finding a cure is an important goal of research on brain diseases. However, to patients and their loved ones, research that can help preserve or restore functional ability in their daily lives is just as crucial. This was one of the takeaways from the first annual WSU Translational Medicine Symposium held last week at the Providence Auditorium in Spokane.

The symposium brought together researchers, entrepreneurs, physicians, patients, and caregivers to share knowledge about treatment innovations and key issues related to brain diseases, the theme for this inaugural event.

WSU Spokane Na-ha-shnee

“That was awesome. That was so much fun.”

Those words came from a high school student immediately after her group finished their session with Sim Man, the mannequin used by the College of Nursing in its simulation lab.

She is one of 20 Native American high school students on campus through June 30 for the 21st Annual Na-ha-shnee Health Sciences Institute.
