Q

B Presence of one or more of the following intrusion symptoms associated with the traumatic event, beginning after the event occurred

A

 Recurrent, involuntary, and intrusive distressing memories of the traumatic event (children younger than 6 might express this as repetitive play)
 Recurrent nightmares related to the trauma (In children there might be no specific content in those dreams)
 Dissociative reactions (e.g., flashbacks) in which the individual feels or acts as if the traumatic event(s) were recurring. (Such reactions may occur on a continuum, with the most extreme expression being a complete loss of awareness of present surroundings.) (In children, trauma-specific reenactment may occur in play)
 Intense or prolonged psychological distress at exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event
 Marked physiological reactions to internal or external cues that symbolize or resemble an aspect of the traumatic event

Q

Co-occurrence with dissociative symptoms

A

 Depersonalization: Persistent or recurrent experiences of feeling detached from, and as if one were an outside observer of, one’s mental processes or body (e.g., feeling as though one were in a dream; feeling a sense of unreality of self or body or of time moving slowly)
 Derealization: Persistent or recurrent experiences of unreality of surroundings (e.g., the world around the individual is experienced as unreal, dreamlike, distant, or distorted)

Q

Dissociative disorder and PTSD (Prevalance)

A

o 1/3 with PTSD also experience DD in form of dissociative amnesia and depersonalisation
o Three connections:
 DD directly after trauma event predicts full blown PTSD, so a tendency to DD makes persons vulnerable for PTSD
 Complex PTSD: server from of PTSD often associated with early age interpersonal trauma and with dissociative symptoms from that early age
 Special DD subtype of PTSD with 30% prevalence in PTSD cases

Q

Depersonalisation disorder

A

Patients believe that they have changed in some way or are in some way no longer real (derealization accounts for same beliefs about the environment)
 Commonly observed in acute stress reactions
 Prominent theory: dysregulation along the hypothalamic-pituitary adrenal axis
• Sometimes successfully treated with anxiolytic or antidepressant drugs (could be primary or secondary effect)

Q

The trauma memory argument

A

 Dissociation might be a defence mechanism to protect themselves
 People who experienced a trauma are unlikely to forget about it they even remember it more vivid
 Derealization and depersonalization occur but amnesia caused by trauma not so much
 Adaption: memory is enhanced for “terror” traumas, such as combat, but impaired by dissociation for “betrayal” traumas, such as incest (not scientifically supported)

Q

Intrusion based reasoning

A

the tendency to interpret distressing intrusions themselves as evidence that danger is impending, regardless of objective danger information (linked to PTSD)
o Method: longitudinal study
o IR is involved onset and maintenance of PTSD symptoms
 IR leads to acute stress and this leads to PTSD (acute stress is mediator)
o People with PTSD rate situations with intrusions as more dangerous

Q

Emotion based reasoning

A

Inferring danger from presence of anxiety responses themselves (If anxiety, then threat).
 Measured with three scenarios specific for panic disorder, social phobia and spider phobia. E-R scenarios were administered last.
 Results – PTSD group showed higher danger ratings on scenarios with anxiety information relative to those without. Also, people high in ER have more difficulty distinguishing safety signals from danger signals compared to individuals low in ER.

Q

Prevalence

A

o Risk to get PTSD until age 75 is 8.7% (USA)
o Twelve month prevalence in US 3.5 most other countries around 0.5-0.1%
o Police firefighter etc have higher risks
o Rape, military combat and captivity and genocides: ranging from one third to 50%
o Younger children show lower prevalence
o Full PTSD is less prevalent in older age but sub-threshold might be higher

18
Q

Development and course

A

o Symptoms usually begin within 3 months but until enough criteria are met it can take years
o Duration of the symptoms: one half has completely recovered after 3 months the rest might need up to 50 years

19
Q

Biological factors

A

 Heritability of 30%
 A relatively small hippocampus
 Underdeveloped amygdala and VMPFC
 Genetically heightened startle response and fear relevant endocrine secretion

20
Q

Avoidance coping (risk factor)

A

increases risk of developing PTSD

21
Q

Dissociation (risk factor)

A

before, during and after increases risk and severity of PTSD

22
Q

Conditioning theory

A

supposes that many of the symptoms are due to classical conditioning
 Might explain flashbacks
 Conditioned fear responses do not extinguish because avoidance behaviour prevents processing of cues (e.g. claps for gun shot)

23
Q

Emotional processing theory

A

creation of representation in memory that becomes strongly connected with other contextual details (e.g. car accident might lead to fear of roads or even travelling)
 Again avoidance of these stimuli prevents normal associations
 Traumas might be so severe that the representations differ to everyday life experiences so they are more persistent
 Fixed word view might make you vulnerable to PTSD

24
Q

Mental defeat

A

A specific frame of mind in which the individual sees themselves as a victim (also in future). This is a psychological factor that is important in making an individual vulnerable o PTSD
 Perceived lack of control might lead to decreased processing of the trauma

25
Q

Dual representation theory

A

explains PTSD by to sperate memory systems
 Verbal accessible memory: registers memories that are consciously processed and retrievable
 Situationally accessible memory: captures information of the vent that might be to fast for conscious processing (e.g. sounds)
• Accounts for flashbacks

26
Q

Temperament (before risk factor)

A

These include childhood emotional problems by age 6 years (e.g., prior traumatic exposure, externalizing or anxiety problems) and prior mental disorders

27
Q

Environmental (before risk factors)

A

• Lower socioeconomic status, lower education, exposure to prior trauma, cultural characteristics (e.g. self-blaming coping strategies) low intelligence, minority group, family psychiatric history

28
Q

Genetic and physiological before risk factors

A

• These include female gender and younger age at the time of trauma exposure (for adults). Certain genotypes may either be protective or increase risk of PTSD after exposure to traumatic events

29
Q

During risk factors

A

severity of the trauma, perceived life threat, personal injury, interpersonal violence and, for military personnel, being a perpetrator, witnessing atrocities, or killing the enemy. Finally, dissociation that occurs during the trauma and persists afterward is a risk factor

30
Q

Posttraumatic factors

A

 Temperamental: These include negative appraisals, inappropriate coping strategies, and development of acute stress disorder
 Environmental: These include subsequent exposure to repeated upsetting reminders, subsequent adverse life events, and financial or other trauma-related losses. Social support (including family stability, for children) is a protective factor that moderates outcome after trauma

31
Q

Cormobdity

A

o Individuals with PTSD are 80% more likely than those without PTSD to have symptoms that meet diagnostic criteria for at least one other mental disorder (e.g., depressive, bipolar, anxiety, or substance use disorders (more common among males))
o most young children with PTSD also have at least one other diagnosis, the patterns of comorbidity are different than in adults, with oppositional defiant disorder and separation anxiety disorder predominating
o there is considerable comorbidity between PTSD and major neurocognitive disorder and some overlapping symptoms between these disorders

32
Q

Psychological debriefing

A

Structured way of trying to intervene development of PTSD directly (24-72 HOURS) after event
o CISM: showing people that they are normal individuals that have experienced something abnormal
o Lost its right, might even be disadvantageous

33
Q

Exposure therapies

A

o What does it does: 1 helps to extinguish traumatic associations 2 helps to disconfirm irrational beliefs caused by trauma
o How: virtual reality, detailed narrative, visualizing fear (Imaginal flooding)

34
Q

Cognitive restructuring

A

evaluate and replace intrusive or negative automatic thoughts and evaluate and change dysfunctional beliefs about the world

35
Q

EMDR

A

o Patient recalls traumatic memories while performing a task which causes bilateral stimulation (looking from left to right/up or down or hearing sounds left and right) tackles working memory
o Eye movement adds effects that cannot be explained by only recall
o Task are used to limit capacity of working memory while recalling traumatic event with the goal to reduce vividness and emotionality of the memory
 During recall memory becomes label and the recall leads to imagination inflation
 SO any tasks affecting working memory can be used

36
Q

Flash forwards (EMDR)

A

EMDR can be used to decrease the tense of prescriptive memory the same way as retrospective memories

37
Q

Working memory capacity (EMDR)

A

people with low WM capacity respond better to EMDR

38
Q

Inverted U shape (EMDR)

A

there needs to be a minimum of taxing, but if this taxing exceeds a certain level there will be too little room for recall. Too little and to much taxing have a negative effect
 Vague memories need to be treated with low WM tax

39
Q

Beeps in EMDR

A

 Might not tax working memory but causes interhemispheric communication
 Small but significant effect (eye movement has 3 times the effect of beeps)
 More satisfactory than eye movement which does not predict actual effectiveness

40
Q

Mindfulness and mindful breathing

A

 Mindfulness-based cognitive therapy (MBCT): Mindful breathing is used to create emotional distance to thought, memories and impulses (esp. used in depression)
 MB and eye movement have the same influence o reaction time (working memory)
 MB might have the same effects as eye movement

41
Q

Treatment effectivity for PTDS and DS

A

o DS does not decrease treatment success of PTSD, but their PTSD was more severe in the beginning and in the end but the proportion of effectiveness was similar in both groups
o PTSD treatment can even decrease DS symptoms

42
Q

Acute stress disorder

A

similar symptoms to PTSD but shorter duration less than one month
