The symptoms of flashbacks, nightmares and hypervigilance may be under
stood by those who have shared or understand a traumatic event, but th
e duration of such symptoms may well outstretch all expectations. Post
-traumatic stress disorder (PTSD) is serious, and may affect the rest
of a sufferer's life. Traumatic situations are ubiquitous in the moder
n-day world, and can occur in both military and civilian settings. A g
reat deal of research into the development and management of PTSD has
been carried out in the past two decades; although many drug treatment
s and psychotherapeutic approaches have been investigated, no single m
ethod has been found to cure all the symptoms successfully.
