Hormone linked to PTSD symptoms
By Staff Writer
A new study on individuals who have been affected by trauma has helped researchers identify a hormone that might serve as an indicator for post traumatic stress disorder (PTSD). These findings may lead to the development of new diagnostic tools and cognitive therapy treatment options for those afflicted by mental health conditions.
There are few biological markers for PTSD and other psychiatric diseases, according to the researchers. However, they have found a link between the hormone known as pituitary adenylate cyclase-activating polypeptide (PACAP) and the condition.
PACAP works throughout the body and brain to modulate activity in the central nervous system and affects metabolism, blood pressure, pain sensitivity and immune function.
Researchers from Emory University and the University of Vermont analyzed data from low-income Atlanta residents who had been exposed to high levels of trauma, which led many participants to develop PTSD.
Women with higher blood levels of the hormone had more symptoms of PTSD. However, there was no association in men. Based on these findings, the researchers believe that men and women who have survived a traumatic experience may develop PTSD through different biological pathways.
This research may help mental healthcare providers distinguish between patients with anxiety disorders from those suffering from behavioral afflictions. In addition, it may help them identify individuals in high stress occupations and environments who may be more likely to develop PTSD.
