21What is PTSD ?
- Confrontation with threat of death or injury
responded to with horror or helplessness, fear
and sense of ruination. - Includes rape, mugging, seeing a bad accident,
killing someone, fighting in a war, being in a
concentration camp, even losing a loved one or
being sued in court. - Acute PTSD symptoms last for less than three
months. - Chronic PTSD symptoms persist for more than
three months, or first appear more than six
months after the traumatic event.
22What is PTSD? Symptoms
- Wide range of emotional, behavioral and somatic
symptoms - Reliving of trauma, pervasive numbness, and
anxiety are some of the most common symptoms. - Often, the patient cannot remember important
parts of what happened to them - Many PTSD sufferers feel pessimistic about their
future, and worry what will happen to them and
their loved ones - Symptoms may persist and interfere with many
areas of functioning for a long time, even
decades.
23Long-Term Traumatic Effects
- Krystal (1968) found that 97 of Nazi
concentration camp survives out of a sample of
149 still had anxiety twenty years later - 71 had persecution nightmares
- 80 suffered survivor guilt, self-reproach,
depression, and crying spells - Kuch and Cox (1992) found that even 40 years
later, Auschwitz survivors were 3 times more
likely to have PTSD than holocaust survivors who
were not in concentration camps.
24Long-Term Traumatic Effects
- Engdahl et al (1997) out of 262 WWII and Korean
War veterans who were POWs, 53 had experienced
PTSD, and 29 still had it 50 years later. - Yehuda, Halligan and Bierer (2002) (in reading
packet) found that children of Holocaust
survivors are at greater risk for PTSD because of
their lower than normal cortisol levels. - Foa et al (1992,1997) 95 of rape victims have
PTSD two weeks after the event 70 recover in a
few months. - However, 25 do not recover after even 4-6 years
17 years later, 16 of victims still have PTSD.
25Epidemiology
- Lifetime prevalence rates are 10 in women, 5 in
men. - 7.8 percent of Americans will experience PTSD at
some point in their lives. - About 3.6 percent of U.S. adults aged 18 to 54
(5.2 million people) have PTSD during the course
of a given year.
- Although most people show signs of trauma after a
terrible experience, studies show that about 8
of men and 20 of women go on to develop
full-blown PTSD, and roughly 30 of these develop
a chronic form that persists throughout their
lifetimes.
26Epidemiology
- The traumatic events most often associated with
PTSD for men are rape, combat exposure, childhood
neglect, and childhood physical abuse. - The most traumatic events for women are rape,
sexual molestation, physical attack, being
threatened with a weapon, and childhood physical
abuse.
- The disorder is particularly common in veterans
an estimated 30 of people who spend time in war
zones get PTSD. - The National Vietnam Veterans Readjustment Study
estimated in 1988 that the prevalence of PTSD in
that group was 15.2 at that time, and that 30
of veterans had experienced the disorder at some
point since returning from Vietnam.
27Who is most at risk for PTSD?
- Those with prior vulnerability factors such as
genetics, early age of onset and longer-lasting
childhood trauma, lack of functional social
support, and concurrent stressful life events - Those who report greater perceived threat or
danger, suffering, upset, terror, and horror or
fear - Those with a social environment that produces
shame, guilt, stigmatization, or self-hatred
people with less education and lower SES are at
greater risk. - Those who experience greater stressor magnitude
and intensity, unpredictability,
uncontrollability, sexual (as opposed to
nonsexual) victimization, real or perceived
responsibility, and betrayal. - Psychologically healthy people and those who are
better prepared for the traumatic event (like
knowing a hurricane is going to hit) are less
likely to get PTSD afterwards.
28Other risk factors for PTSD
- Genetic component identical twins who served in
Vietnam show more similar PTSD symptoms than
fraternal twins (True et al 1993) - This could be a result of underlying neural
circuitry, but no exact reason is known.
29Psychological Aspects
- People who suffer from PTSD often relive the
experience through nightmares and flashbacks and
have difficulty sleeping - Avoid things that remind them of the trauma
- feel detached or estranged, even from loved ones,
and want to be left alone - Decreased interest in normal activities
- Become over-alert (hypervigilant) to stimuli that
remind them of the trauma - Trouble concentrating on work and study
- Outbursts of hostility and anger
- Obviously, these symptoms can impair daily
functioning.
30Psychological Aspects
- The disorder is often comorbid with depression,
substance abuse, and problems of memory and
cognition, like dissociative amnesia. - In a large-scale study, 88 percent of men and 79
percent of women with PTSD met criteria for
another psychiatric disorder. - For men alcohol abuse or dependence (51.9
percent), major depressive episodes (47.9
percent), conduct disorders (43.3 percent), and
drug abuse and dependence (34.5 percent). - For women major depressive disorders (48.5
percent), simple phobias (29 percent), social
phobias (28.4 percent), and alcohol
abuse/dependence (27.9 percent). - (Courtesy of the National Center for PTSD)
31Biological Aspects
- May affect both the central and autonomic nervous
systems - altered brainwave activity
- decreased volume of and damage to the hippocampus
(abnormalities with long-term memory) because of
excessive hormone exposure - abnormal activation (increased blood flow) the
amygdala - involved in coordinating the fear response and
memory - More blood flow in the cingulate gyrus, reduced
blood flow in Brocas area, which is responsible
for spoken language.
32Biological Aspects
- Psychophysiological problems
- hyper-arousal of the sympathetic nervous system
- increased sensitivity of the startle reflex
- sleep abnormalities
- Enhanced thyroid function
- Abused children have smaller corpus callosums,
which allow communication between brain
hemispheres. - They also have chronic overarousal of the
autonomic nervous system, faster resting heart
rate, stress-related changes (Bremner et al 1997)
33Biological Aspects How PTSD is Related to Stress
Pathways
- Lifelong increase in HPA axis activity
- Cortisol levels lower than normal
- Yehuda et. al Holocaust survivor study of
urinary cortisol excretion. - Epinephrine and norepinephrine levels higher than
normal - High levels of natural opiates in the brain
- These neurohormonal changes are particularly
interesting because they are the opposite of what
happens when people get depression this occurs
even when PTSD is comorbid with depression!
34Biological Aspects Somatic Symptoms
- Many people with PTSD experience a variety of
physical complaints, which may be psychogenic in
origin often, they seek treatment from a
physician without knowing they have PTSD.
- Headaches
- gastrointestinal disturbances
- immune system problems
- dizziness
- chest pain
- general physical discomfort in other parts of the
body
35Social Aspects
- PTSD is associated with decreased ability to
function in social or family life, including
occupational instability, marital problems and
divorce, family discord, and difficulty
parenting. - For example, in one study,Vietnam veterans with
PTSD exhibited problems in family and other
interpersonal relationships, problems with
employment, and involvement with the criminal
justice system.
36Treating PTSD
- PTSD is diagnosed using a combination of
questionnaires, structured interviews, and
diagnostic tests. - Early intervention with both stress inoculation
and exposure therapy may work well. - Drugs have been proven mostly ineffective
however, some moderate effects have been found
with selective serotonin reuptake inhibitors
(SSRI) like Prozac and Zoloft. These help reduce
anxiety, depression, and sleep disturbances.
37Treatment Clinical Methods
- Prolonged Exposure Therapy (PET)
- Patients relive trauma by describing it to a
therapist repeatedly over many sessions and tries
not to dissociate from memories - Group Therapy
- Patients with PTSD meet with one another to
provide social support and a safe place to
disclose what happened to them - Stress Inoculation Training (SIT)
- Anxiety management techniques, deep muscle
relaxation, positive cognitions and prevention of
dwelling on traumatic thoughts - Eye Movement Desensitization and Reprocessing
- EMDR teaches patients to think of a disturbing
memory, then focus on the therapist moving
his/her finger rapidly in front of patients
face- saccadic eye movements. Results in strong,
almost immediate improvement, but is very
controversial
