Post-Traumatic Stress Disorder
What is Post-Traumatic Stress Disorder
Post-traumatic stress disorder can occur after a person is exposed to actual or threatened death, serious injury or sexual violation. Examples such as traumatic events including terrorist attacks, mass shootings, warfare and severe weather events (cyclone, tsunami and bushfires) can trigger such a disorder.
A major symptom is re-experiencing the trauma. This may be in the form of recurrent dreams of the event, flashbacks, intrusive memories or unrest in situations that bring back memories of the original trauma.
