Post traumatic stress disorder is a mental illness that impacts many around the world. Genetic link has been found between PTSD and schizophrenia, and since schizophrenia is more common in women, this suggests that women are also at greater risk for PTSD. A recent study looked into the genetics of those that have PTSD and those that have lived through traumatic events and not developed the mental illness. They believed that genetic variation was the reason why a person would be resilient to PTSD or be at risk for it. The study focused on about 20000 people from 11 different ethnic backgrounds. The found that 29% of the risk of getting PTSD is contributed to genes. This puts PTSD as one of the most genetically influenced mental illness. Researchers hope by being able to identify a patient's risk for getting PTSD that they can take preventative measures to make sure that they do not experience PTSD. I think that this is going to be very helpful to a lot of people if they are able to determine a person's risk for developing this mental illness. By implementing preventative measures for a person at risk, hopefully the amount of people that live with post-traumatic stress disorder will decrease.
