As far as I know, PTSD was first used as a broader label for symptoms associated with so-called shell-shock, and has been diagnosed for symptoms of a milder nature.
But is there a lower limit to the point at which PTSD can be diagnosed? For example, is it possible to have such a mild form of PTSD that it does not interfere with normal functioning, but exhibits the same features?
The reason I ask, is I live in the UK where the National Health System (NHS) is increasingly struggling with funding. Their website on PTSD seems to only state the most extreme of traumatic events as possible causes. In short, I think it is to get out of giving help to all but the absolute worst cases. Hospitals and many mental health services have large burdens and turn many seeking help away.
If someone where to suggest they have PTSD, I feel that with literature such as the above, it belittles anyone experiencing "mild" events such as domestic abuse, which barely fits into their categories. Not only might they not get treated, but experience or perceive scorn.
If one were to seek help for PTSD and have to justify the help needed, regardless of the cause, how might it be done? Could the symptoms be misdiagnosed as, for example, regular stress, or anxiety, and would treatment for those be different to that required to help with PTSD?
