The study, which was conducted by researchers from Emory University and the University of Vermon and published in the online journal Nature, hopes that the discovery of this hormone will open a new window into the biology of the condition.
The study itself involved assessing 64 traumatised individuals, among whom several had developed PTSD. After the experts measured the PACAP blood levels in all of the participants, they actually found that symptom scores were five times higher among women with above-average PACAP levels than among women with below-average PACAP levels.
The researchers also conducted an additional study to further cement their findings, only this time with 74 traumatised patients. Again the results showed that high levels of PACAP seemed to correlate with PTSD symptoms.
PTSD disorder can be extremely difficult and distressing to deal with, and the researchers hope their discovery may lead to stress relief strategies playing a more active role in treatment and services dedicated to the condition.
