June is recognized as Post Traumatic Stress Disorder (PTSD) month. 

PTSD is common among veterans returning from war who experience flashbacks, nightmares, and extreme distress when reminded of past triggering events. Dr. Jill Schreiber is a clinical psychotherapist at OSF HealthCare in Alton and says there are many causes of PTSD.

It is estimated that there are currently about 12 million people in the United States living with PTSD.
