All this research is new. they say in some of the articles that more testing needs to be done to include more women (who show more immune system problems from PTSD than men) because the few they tested didn't give them enough data to report the percentages correctly.

the study in Michigan was only approved for publication in April of 2010. it's so sad. i try so hard not to get mad when the general psychiatric community doesn't give credence to physical effects from mental conditions. well, now there's a proven link with "epigenetic changes in immune-system genes" of people with PTSD. i just want to say to them "hurry, hurry, hurry!"
