Mental Illness Awareness Week, observed this year from October 3 through 9, brings attention and support to the many patients and families who are coping with a variety of psychological conditions. Although an estimated 20 percent of U.S. adults and nearly 17 percent of youth have some type of mental health ailment, these conditions are still not well understood. However, research conducted at the National Institute of Mental Health (NIMH) is transforming our knowledge of one such mental health condition that affects more than two million Americans: bipolar disorder.

Postbac Poster Day Showcases Young Scientific Talent

Scientists-in-Training Impress at Virtual Event

Despite the challenges of working during a global pandemic, IRP scientists continue to make groundbreaking discoveries and mentor the next generation of researchers. This includes the hundreds of recent college graduates conducting research in NIH labs through the Postbaccalaureate IRTA program. On April 28, 29, and 30, many of these budding scientists presented the fruits of their efforts at this year’s virtual Postbac Poster Day. Read on to learn about a small sampling of the scientific strides NIH’s postbacs are making.

Facing Daytime Discrimination Linked to Sleep Struggles

IRP Study Examines Overlooked Contributor to Racial Health Disparities

Recent news coverage of the deaths of George Floyd, Ahmaud Arbery, and Breonna Taylor, along with statistics reporting startlingly disproportionate death rates among black Americans infected with COVID-19, have made it clear that racial biases can be a matter of life and death. Meanwhile, it can be easy to overlook other, more subtle ways that discrimination can affect health, such as new IRP research that links instances of discrimination to poor sleep.

Postbac Poster Day Highlights Budding Researchers

On Wednesday, May 2, hundreds of researchers gathered at NIH’s Natcher Conference Center to show off their recent discoveries. But unlike a typical scientific conference, the letters “M.D.” and “Ph.D.” were noticeably absent from these scientists’ credentials. Instead, the event — NIH’s annual Postbac Poster Day — celebrated the accomplishments of individuals participating in the NIH Postbaccalaureate Intramural Research Training Award (IRTA) Program.

Sleep Apnea Produces Troubling Signs of Future Brain Disease

Like a bear leaves its ominous footprints in the snow, diseases and other biological processes often leave traces throughout our bodies. Recent technological and scientific advances have enabled clinicians to use measurements of these ‘biomarkers’ in their attempts to improve our health. A new study by IRP researchers revealed that patients with a sleep disorder called obstructive sleep apnea (OSA) have higher blood concentrations of certain biomarkers that may foreshadow poor brain health later in life.1

When people with OSA sleep, their throat muscles relax and block their windpipes, preventing proper breathing and often waking them up. As a result, these individuals get lower-quality sleep and their brains receive less oxygen at night.

“The overall idea is that those two conditions are not good for brain health, but nobody had really looked to see if some of the biomarkers we see in brain injury are also common in younger individuals with this type of disordered breathing,” says IRP Lasker Clinical Research Scholar Jessica Gill, Ph.D., R.N., the study’s senior author.
