Q

What can a traumatic event be?

A

Any negative experience. Everybody perceives different events as traumatic or non-traumatic. Factors that determine in each one of us what might be traumatic or not are a lot, and we can’t always know them all (personality, past experiences, associations, memories, environment etc.)
!!! Reminder of a traumatic event might not cause PTSD. Then a change in your life might change the way you think, and the same reminder that caused you no harm, now brings about symptoms of PTSD !!!

Women (1.5-2 times more likely to develop PTSD than men). This happens mainly due to different life circumstances (sexual assault in childhood and adulthood):
- 1 of 6 women: raped
- 1 of 10 women: physical harm after refusing physical contact

Q

What is Complex PTSD?

A

Usually comes about when somebody is exposed to prolonged trauma or/and had childhood disorders as well.
- Shows a broader range of symptoms than PTSD
- Because it’s just more severe PTSD symptoms, there’s no distinctive subtype, so DSM-5 doesn’t classify it as a specific disorder.

Q

What are some general criteria for PTSD?

A
  • Duration of symptoms: at least 1 month
  • Psychological symptoms aren’t caused by any substance use
  • Disturbance causes clinically significant distress or impairment in social, occupational or other forms of functioning
20
Q

What are some other general characteristics of PTSD?

A
  • Usually comorbid with another disorder
  • Culture shapes risk for PTSD: Minorities in U.S., Northern Ireland -> more conflict, therefore more PTSD
  • Usually people go from ASD to PTSD (50% of people that have ASD develop PTSD)
  • PTSD can also develop though from nothing (no ASD)
21
Q

What are the differences between ASD (Acute Stress Disorder) and PTSD?

A
  • ASD has a broader range of diagnostic criteria than PTSD (specifically, it doesn’t specify that symptoms from each of the 4 symptom categories of PTSD must be present for somebody to be diagnosed with ASD)
  • Diagnosis is applicable only when symptoms last for 3 days to maximum a month
22
Q

What are some problems with the ASD Diagnosis?

A
  • Stigmatizes very common reactions to trauma, reactions that aren’t indicative of any problem/disorder and are very healthy and natural
  • Not predictive of who will develop PTSD (less than1/2 of those who have ASD don’t develop PTSD)
23
Q

]What is a good aspect with ASD Diagnosis?

A

Helps us identify those who need some support after trauma

24
Q

What is Adjustment Disorder?

A
  • When somebody has experienced a trauma, but doesn’t meet all criteria for PTSD or ASD
  • When somebody meets all criteria for PTSD or ASD, but hasn’t experienced a traumatic event (symptoms come about from a rather trivial event)
25
Q

Etiology of PTSD

A
26
Q

What does Etiology mean?

A
  • Factors that increase likelihood for a disease/disorder
  • Causes for a disease/disorder
  • (In this case as well) Factors that either perpetuate or reduce the prevalence of a disease/disorder
27
Q

What are the three risk factors/factors that influence the likelihood of PTSD?

A
  • Severity and Nature of Trauma
  • Neurobiology (then specifically hippocampus)
  • Coping mechanisms
28
Q

Severity and Nature of Trauma

A
  • More severe, more likely to develop PTSD
  • Nature: More likely for PTSD to develop if trauma is caused by humans instead of something else (e.g. natural disorders)
29
Q

Neurobiology

A
  • dysregulation of amygdala & PFC
  • Increased release of norepinpehrine: hyperreactivity to threat-related stimuli
  • Disrupted Brain networks
    ~Salience Network (process/respond to emotionally relevant stimuli)
    ~ Central executive Network (Regulate emotions
    ~ Default mode Network (introspection, processing of self-relevant memories)
  • Hippocampus
30
Q

How can the hippocampus play a role in developing and having PTSD?

A

Dysfunction/diminished activation of hippocampus during cognitive tasks/emotion regulation makes it difficult for people to analyze memories of a traumatic event or put them into context. This leads to excessive fear and stress, even when there’s just a reminder of trauma, completely out of context

31
Q

Coping mechanisms - Maladaptive Strategies

A
  • Avoid thinking about trauma
    -Dissociation: Feeling removed from body’s thoughts/emotions.
    -> People use this strategy to avoid conftronting memories of trauma
    -> Levels of dissociation are highest in the weeks after the trauma, and slowly diminish
    -> Symptoms of Dissociation show immediately after/during trauma = more likely to develop PTSD
    Both strategies increase likelihood for PTSD
32
Q

Coping mechanisms - Adaptive Strategies

A
  • Strong Social Support
  • Cognitive/intellectual ability -> make sense of horrifying events
33
Q

What are some other general risk factors that predict PTSD?

A
  • Family Psychiatric History
  • Low SES
  • Race
  • Younger Age
  • Life Stress
34
Q

What is the Cognitive Model of PTSD?

A

(Image from slide, page 21)

35
Q

Treatment of PTSD and ASD

A
36
Q

What is the medical treatment for PTSD?

A
  • Paxil and Zoloft: Serotonin reuptake inhibitors (SSRI’s): more serotonin flow through the brain
  • Antidepressants maybe work. A problem with them is that the relapse of people with PTSD is often discontinued, and patients go back to were they were.
  • Benzodiazepines (used for anxiety disorders) are sometimes prescribed: no scientific evidence to support this
37
Q

Is medical or psychological treatment preferred?

A

Psychological

38
Q

What are some psychological treatment methods for PTSD?

A
  • Prolonged Exposure Therapy (!!! Learning Theory !!!)
    ~ Imaginal Exposure Therapy
    ~ Virtual Reality
    ~ EMDR
  • Cognitive Therapy
  • (NET) (Not that important)
39
Q

What is the best and most common psychological treatment method for PTSD?

A

Prolonged Exposure Therapy (Benefits persist for over 5 years)
- 8-15 90 minute sessions, once or twice per week

40
Q

What is the goal of Prolonged Exposure Therapy?

A
  • Make the general fear response go away
  • Challenge the idea that the person can’t cope with the fear and anxiety generated by trauma-related stimuli
41
Q

On which theory is the idea of exposure therapy based on, and what does that theory state?

A

Learning Theory
!!! If there’s an association between CS - fearful US, the therapist tries to pair the same CS with non-fearful US. this new association between CS - non-fearful US competes/inhibits with the original association of CS - fearful US !!!

42
Q

What are the methods of Prolonged Exposure Therapy

A
  • Face worst memories through exposure: hierarchical exposure (from less intense to most intense fears)
    ~ a lot of times exposure in vivo as well (return to scene of traumatic event)
  • Challenge negative beliefs about self: develop more positive narrative about ability to cope with trauma
    ~ CPT (Cognitive Processing Therapy) helps in this: Especially good in reducing self-blame and guilt
  • Because trauma can interfere with ability to cope with emotions, it’s important to teach people emotion regulation skills
  • Psychoeducation on nature of PTSD
  • Breathing exercises for relaxation
43
Q

What are some variations on Exposure Therapy?

A
  • Imaginal exposure: If in exposure therapy it’s too difficult for patient to return to scene of traumatic event, therapists instead deliberately ask patients to remember the event
  • Virtual reality: not as effective
  • EMDR
44
Q

What is EMDR? (Eye Movement Desensitization and Reprocessing)

A

Recall trauma-related scene while therapist moves fingers back and forth in front of the client’s eyes -> helps reduce vividness and intensity of memories

45
Q

How is the effectiveness of EMDR explained?

A

1/. long-term memory (traumatic memory)
2/. working memory
3/. fingers moving: competing tasks (recall memory, focus on moving fingers) makes us balance out how many resources we focus on each task. Thus we focus less resources recalling memory than we usually do, reducing the vividness/emotionality of memory
4/. Modified memory gets reconsolidated into long-term memory

46
Q

How is Cognitive Therapy used to tackle PTSD?

A
  • Identify and challenge
    dysfunctional/negative cognitions
  • often combined with
    ~ Exposure Therapy
    ~ CBT
47
Q

Is it possible to prevent PTSD by treating people with ASD?

A

Yes.
Early exposure therapy:
- Risk of PTSD is reduced from 58% to 32%
- PTSD symptoms are less severe (if ASD treatment doesn’t completely help tackle ASD and PTSD develops)
