This information is primarily aimed at those who have been in the forces, but PTSD can affect anybody who has been through a particularly traumatic event in their lives, one which has usually meant great physical danger.
Psychologically, some people find it very difficult to deal with the strong imprint that this can create on their memories and go on to suffer symptoms which might include nightmares or flashbacks.
This can have a big impact on their lives, including their relationships or ability to work, especially if they are seeking to adjust to life outside the forces. There are, however, a number of treatments available, and understanding of the condition has advanced in the last few tears.
