Scientists have developed a therapy that can cure PTSD in army veterans in just three weeks.
The treatment is known as prolonged exposure therapy and works by forcing soldiers to confront painful memories of life at war.
The therapy has been found to alleviate symptoms of PTSD in more than 60 per cent of sufferers.
Academics in the US claim that the method will help veterans from conflicts in Iraq and Afghanistan and could one day be used to help those who are fighting in Ukraine.
The therapy makes veterans retell their stories and do activities they would otherwise avoid as they trigger terrible memories.
Dr. Alan Peterson, from the University of Texas, said: "While condensed treatments may not be feasible for everyone, results show compressed formats adapted to the military context resulted in significant, meaningful and lasting improvements in PTSD."
