Anthony-
Here is a very reliable source from the US checked over on FEB 24,2011.

This site is the National Institute of Mental Health. What it says is:
Post-Traumatic Stress Disorder (PTSD)
Approximately 7.7 million American adults age 18 and older, or about 3.5 percent of people in this age group in a given year, have PTSD.1, 2
PTSD can develop at any age, including childhood, but research shows that the median age of onset is 23 years.5
About 19 percent of Vietnam veterans experienced PTSD at some point after the war.13 The disorder also frequently occurs after violent personal assaults such as rape, mugging, or domestic violence; terrorism; natural or human-caused disasters; and accidents.
One other site of interest. This gives statistics for many countries. There is a 4 person per day diagnosis difference between the UK and the US. This site was also checked over FEB 2011.

I do believe that many physicians are money hungry. I think it is very unfortunate. Many of our physicians do what we call "waste basket diagnosis" with things like ADD, ADHD, Depression and I am sure PTSD falls into that. If they are frustrated then their quick answer is to fix it with a pill. However, more often than not you find very reputable physicians who are not like that. They give you time and patience. They work with you, not against you.
Just my humble thoughts.
