Gene Screens for PTSD
I read an article in Psychology Today, and was especially interested in it as it relates to my final project. The article is about a study done (the first to ever be published, in the Journal of Affective Disorders) regarding the influence of genes in PTSD. The study was done by a team of scientists from both UCLA and Duke, and their findings were that certain genes can heighten the risk, or create a greater predisposition, to getting PTSD.
But that was it. After that, I had practically no information on the conductors of the study, or really what they even found or did. So I did a little more research, and found a much more comprehensive article on Sciencedaily.com. It explained who the researchers were, and more importantly (to me at least) what the genes affecting PTSD were about: they are called TPH1 and TPH2, and control serotonin production (a neurotransmitter in the brain that regulates mood, sleep and alertness).
So, despite from being an interesting scientific find (that is very, VERY far from being applied in the real world), I learned a little bit about questioning what you read, and doing a bit more research sometimes to find what you are really looking for.
What do you think? If you compared the two articles, what did you think the differences/similarities were? Or, if you don’t want to do that, what do you think of this study in more scientific terms – do you think it’s reliable? Useful? Is it something that should continued to be explored?
