WASHINGTON — Researchers at Georgetown University Medical Center have found distinct molecular signatures in two brain disorders long thought to be psychological in origin — chronic fatigue syndrome (CFS) and Gulf War Illness (GWI).
In addition, the work supports a previous observation by GUMC investigators of two variants of GWI. The disorders share commonalities, such as pain, fatigue, cognitive dysfunction and exhaustion after exercise.
Their study, published in Scientific Reports, lays groundwork needed to understand these disorders in order to diagnosis and treat them effectively, says senior investigator, James N. Baraniuk, MD, professor of medicine at Georgetown University School of Medicine. Narayan Shivapurkar, PhD, assistant professor of oncology at the medical school worked with Baraniuk on the research.
The changes in brain chemistry — observed in levels of miRNAs that turn protein production on or off — were seen 24 hours after riding a stationary bike for 25 minutes.
“We clearly see three different patterns in the brain’s production of these molecules in the CFS group and the two GWI phenotypes,” says Baraniuk. “This news will be well received by patients who suffer from these disorders who are misdiagnosed and instead may be treated for depression or other mental disorders.”
