By: McKenzie Kaufman

2. What is PTSD?
PTSD, or Post-traumatic stress disorder is a type of anxiety disorder that usually occurs after an experience or traumatic event that is seen as life threatening.
Hurricane Katrina, World Trade Center bombings, The Holocaust, War in Iraq.

3. Symptoms Repeated “reliving” of the event Avoidance Arousal
Flashbacks, dreams, and physical reactions to situations that feel similar.
Avoidance
Emotional numbing, detachment, lack of interest in normal activities, sense of having no future.
Arousal
Difficulty concentrating, hyper-vigilance, outbursts of anger, insomnia.
Other symptoms include:
Dizziness, palpitations, paleness, agitation.

4. Etiology
PTSD can occur immediately after a major traumatic event or may take up to six months.
Can occur in anyone at any age.
Cause is unknown, but psychological, genetic, physical, and social factors are involved. PTSD changes the body’s response to stress and it affects the stress hormones and chemicals that carry information between the nerves (neurotransmitters).
Having been exposed to trauma in the past may increase the risk of PTSD.

5. Diagnosis
There are no tests that can be done to diagnose PTSD. The diagnosis is made based on a certain set of symptoms that continue after you've had extreme trauma.
Psychiatric and physical exams may be conducted to rule out other illnesses.

6. Treatments
Treatment aims to reduce symptoms by encouraging recollection of the event, expressing feelings, and gaining some sense of control over the experience.
People with PTSD may need to treat depression, alcohol or substance abuse, or related medical conditions before addressing symptoms of PTSD.
Behavioral therapy is used to treat avoidance symptoms. This can include being exposed to the object that triggers your symptoms until you become used to it.
Medicines that act on the nervous system can help reduce anxiety and other symptoms of PTSD.
Prozac, selective serotonin reuptake inhibitors (SSRI’S), antidepressants.

7. Prognosis
The best outcome depends on how soon the symptoms develop after the trauma, and on how quickly you get diagnosed and treated.

8. Comorbidity
When PTSD is prevalent, other disorders are likely to be found.
Depression, substance abuse, anxiety
