2. Post Traumatic Stress Disorder or
PTSD
Post traumatic stress disorder or PTSD, as defined by
the Diagnostic Statistical Manual of Mental Health
disorders Fourth Edition (healmyptsd.com), is the
development of symptoms following exposure to an
extreme stressor involving:
Direct personal experience of an event that
involves actual or threatened death or serious
injury, or threat to one's physical integrity.
Witnessing an event that involves death, injury, or a
threat to the physical integrity of another person
Learning about unexpected or violent death,
serious harm, or threat of death or injury
experienced by a family member or their close
associate.
The person’s response to the event must involve
intense fear, helplessness, or horror (or in children, the
response must involve disorganized or agitated
behavior).
3. In the Brain
Studies suggest there are three areas in the brain
that are different in those with PTSD (Nutt, Malizia
pubmed.gov): The hippocampus, amygdala, and the
medial frontal cortex.
It is suggested that the symptoms of PTSD may be
related to a failure of “higher functioning” brain
regions, the hippocampus and the medial cortex, to
dampen or soften the symptoms of the arousal and
distress that are being experienced and mediated
through the amygdala.
4. In the Brain Cont’d
Memory is a key component to PTSD
because the traumatic event may be relived
constantly via memory.
Both the amygdala and the hippocampus
are key in human memory
It is believed that the amygdala is the “fear
center” of the brain
Persons with PTSD have an over active
amygdala
The hippocampus is smaller in those with
PTSD when compared to those without the
disorder (Wang, Xiao, 138-144) This may be
due to the trauma or genetics, the jury is still
out!
5. Symptoms of PTSD
As in the book Traumatic Brain Injury and PTSD (57, 58), There
are many characteristics of PTSD including, but not limited to:
Startling easily
Reliving the traumatic event, chronic or intrusive recalling of
the event
Nightmares, night terrors, and night sweats
Feeling numbness, distant or sad
Aggressiveness and violence
Addiction
Depression and/or contemplation of suicide
Guilt – this can come from feelings like “why did I live and
they didn’t?” or “this was my fault”
Flashbacks – Which may include triggers like sounds,
smells, feelings, and loud noises
Avoidance of places or social events that spark memories
and the anniversary of the event.

6. How likely are YOU to get PTSD?
The likelihood of someone getting PTSD
depends on many factors such as:
How severe the trauma was
If you were injured
The intensity of your reaction
Whether someone close to you was injured
How much your life was in danger
How much you felt out of control
How much help and support you got following the
event (Lawhorne, Philpott; 58, 162)
7. Treatment for PTSD
There seems to be many different
treatments for PTSD
Treatment usually comes in the
form of psychotherapy (“talk”
therapy), medication or both
(Lawhorne, Philpott, 113-137).
There are always new ways to deal
with the disorder and one a newer
treatment is called Neurofeedback

if for awareness, education, and treatment of the disorder. This particular segment of the website was
created o define what PTSD is.

The correlation between PTSD and three areas of the brain is examined. The change in function between
the amygdala and the hippocampus is explored along with the changes in one’s behavior.

The functional alterations in the traumatized brain are discussed. The article explores evidence of brain
changes with focus on functional changes in the amygdala, hippocampus, and the medial prefrontal cortex.
