What is PTSD?
PTSD symptoms fall in in four broad categories:
Intrusions are repeated, involuntary memories, distressing
dreams, or flashbacks of the traumatic event.
Flashbacks may be so vivid that people feel they are re-living
the traumatic experience.
These symptoms may include avoiding people, places, activities,
objects, and situations that bring on distressing memories.
People may try to avoid remembering or thinking about the traumatic event.
They may also resist talking about what happened or how they feel about it.
NEGATIVE CHANGES IN THOUGHTS & FEELINGS
Individuals may have the following symptoms:
Distorted beliefs about oneself, others, or the world
Feelings of ongoing fear, horror, anger, guilt, or shame
Much less interest in activities they previously enjoyed
Feelings of being detached or estranged from others
(e.g., "I am bad," "No one can be trusted")
CHANGES IN AROUSAL & REACTIVITY
These symptoms may include:
Behaving recklessly or in a self-destructive way
Being easily startled
Having problems concentrating or sleeping
Being irritable and having angry outbursts
