On June 27, we talk about PTSD, a complex disorder caused by experiencing or witnessing trauma. The trauma necessary to cause PTSD can originate from many events — potentially an accident, combat, a natural disaster, or an assault — but there are other ways PTSD symptoms can arise. A trained professional must diagnose PTSD, based on symptoms like hypervigilance, mood swings, recurring and involuntary flashbacks to the trauma, and avoidance. The National Center for PTSD declared all of June to be PTSD Awareness month — you can help their campaign by educating yourself and others about the illness, and sharing help with those who might need it.
