Because of the criteria involved only qualified mental health professionals are able to make an accurate PTSD diagnosis, suggests the Department of Veterans Affairs. In some cases quizzes are useful early diagnostic tools for people who are trying to determine whether they need to consult a mental health professional.
Post-traumatic stress disorder, or PTSD, is a complex, broad diagnosis covering a range of symptoms or resultant behaviors. All sufferers' problems start with exposure to a traumatic event, which is typically something well outside the range of normal experience. These include war, torture, and natural or man-made disasters, says the VA. The actual symptoms and symptom severity suffered by any given patient sometimes vary significantly.
