New blood test could accurately diagnosis PTSD. Researchers at the Indiana University School of Medicine in Indianapolis have provided samples of genetic markers to develop a blood test post-traumatic stress disorder (PTSD).
PTSD is a psychiatric disorder that develops in people who have experienced a shocking, witnessed, or dangerous event.
Now the researchers explained that they have identified the biomarker gene expression signatures that, according to them, could support prevention and help to improve treatments. Additionally, they also beleive that a blood test could help identify the risk of future traumatic stress.
The team analyzed more than 250 veterans at the Indianapolis VA Medical Center. They explain that PTSD can affect anyone and its symptoms can come and go with equal intensity. Factors such as suffering an injury or facing ong-lasting trauma can highly increase risk of developing PTSD.
According to estimates, in the United States, around half of the population have experienced life-threatening events and of them, 10 percent of men and 20 percent of women will develop PTSD in their lives.
The researchers’ analysis found that “biomarker signatures” may help discover which compunds effective to treat PTSD could benefit an individual. They are now working to translate the research findings into clinical practice.
“By understanding in a biological way a patient’s illnesses and their mental health challenges, we could treat what they have better, preventing future episodes,” said Alexander B. Niculescu, who is a senior study author and a professor of psychiatry.
