Posttraumatic Stress Disorder (PTSD)

Post-traumatic stress disorder (PTSD) can develop following a traumatic event that threatens your safety or makes you feel helpless.
Most people associate PTSD with battle-scarred soldiers—and military combat is the most common cause in men—but any overwhelming life experience can trigger PTSD, especially if the event feels unpredictable and uncontrollable.
Post-traumatic stress disorder (PTSD) can affect those who personally experience the catastrophe, those who witness it, and those who pick up the pieces afterwards, including emergency workers and law enforcement officers. It can even occur in the friends or family members of those who went through the actual trauma.
PTSD develops differently from person to person. While the symptoms of PTSD most commonly develop in the hours or days following the traumatic event, it can sometimes take weeks, months, or even years before they appear.
