According to a recent announcement of researchers, they noted several genetic markers that could be helpful in determining the risks of developing post-traumatic stress disorder among the United States soldiers.

After that, the researchers were trying to find that link. To do so, they took some blood samples from United States Marines and examined them. Blood samples were taken before and after deployment.

As per Michael S. Breen, a researcher from the University of Southampton and senior study author, after comparing US Marines who develop post-traumatic stress disorder symptoms to those who do not, difference in genes can be measured. Breen said that measurement of dynamic relationships could be helpful in knowing the pathology of PTSD.

During the study, Dewleen Baker from the University of California and some of her colleagues examined the blood samples of about 200 US marines noting the levels of interferon response. Baker said that the main question is what is stimulating an interferon response prior to PTSD development. “The answer could be any number of factors, ranging from a simple explanation of increased anticipatory stress prior to deployment or more complex scenarios where individuals may have a higher viral load”, she added.

PTSD is a mental condition, which can happen to an individual who experiences an extremely dramatic or terrifying event. Event like military combat, a violent assault or natural disasters could lead a person to suffer from PSTD. A person with PSTD always faces trouble while overcoming the trauma.

In the study, the researchers found that biomarkers actually exist for innate immune response that can be altered by PTSD. According to the researchers, the study could be helpful in advanced PTSD detection. They think that it is important to have a comparative methodology to analyze the differentiated genetic indicators of PSTD.
