PTSD Flashcards
course of PTSD:
type I trauma → ___ __ disorder (3-30d) → ___ (1mo+)
type I trauma → acute stress disorder (3-30d) → PTSD (1mo+)
2 key subtypes of PTSD
- with dissociative symptoms (including derealization or depersonalization)
- severe/complex PTSD (many symptoms, affecting dysregulation, impaired relationship with others, suicidal thoughts. dissociation, negative belief systems)
Note: Etiologies of PTSD
- Neuroendocrine systems in PTSD
- ANS hyperactivity
- Reduced serotonin
- Opioid system reduction in endorphins
- Reduced GABA receptor density
- Glutaminergic dissociative symptoms
- Reduced concentration of neuropeptide Y
- HPA axis hyperexpression.

- e. Insomnia
F) Greater than 1mo of duration
G) Symptoms cause functional impairment
H) Not caused by medical illness/EtOH/drugs
Development of emotional or behavioural symptoms in reponse to an identifiable stressor, within 3 months of onset of the stressor
Clinical significant symptoms of either
- Marked distress out of proportion to severity and intensity of the stressor
- Significant impairment in social, occupational, or other area of function
Not another mental disorder
Not a normal bereavement
No persistence for >6 mo after stressor ends
WHAT IS THIS
Adjustment Disorder
timeline for acute stress disorder
3 days to 1 month after stressor
9+ symptoms from 5 categories
- Intrusion (memories, dreams, dissociation, distress)
- Negative Mood (no positive emotions)
- Dissociative Symptoms (altered sense of reality, amnesia)
- Avoidance (thoughts/feelings, external reminders)
- Arousal (sleep, irritable, hypervigilance, concentration, startle)
5 categories that you need 9+ symptoms from in order to diagnose acute stress disorder
9+ symptoms from 5 categories
- Intrusion (memories, dreams, dissociation, distress)
- Negative Mood (no positive emotions)
- Dissociative Symptoms (altered sense of reality, amnesia)
- Avoidance (thoughts/feelings, external reminders)
- Arousal (sleep, irritable, hypervigilance, concentration, startle)
20-50% prevalence after a trauma
T/F comorbidities for PTSD is common
true
Investigations: comorbidities are very common (80% have 3+ disorders): borderline PD, eating disorder, anxiety ,addiction, somatic symptom disorders, major depression, ADHD
Screen for ACEs
first phase of PTSD managemen
Stabilization phase; develop a therapeutic relationship, risk assessment, treatment setting (out/inpatient, day program), PTSD psychoeducation, relaxation skills (meditation, mindfulness), harm reduction (substance use), pharmacotherapy
T/f pharmacotherapy is just as helpful for PTSD as psychotherapy
false. unlike depression and anxiety where meds are truly beneficial, psychotherapy is way better for PTSH. Pharmacotherapy is often only indicated if you have a safet risk or comorbid condition (ex/ functionally impaired because of MDD in addition to trauma)
Pharmacotherapy (trauma therapy >>> medications): indicated with safety risk, psychosis, severe symptoms, functional impairment with ADHD
§ 1st line: fluoxetine, paroxetine, sertraline, venlafaxine
§ 2nd line: fluvoxamine, mirtazapine, phenelzine
**insufficient evidence for meds to prevent PTSD
Habituation therapy for PTSD
decrease in response to a stimulus after repeated presentations. Each time you stay in the situation, your fear goes down. When you stay in a feared situation for a prolonged period, you learn that it is safe, and your anxiety goes down.
accelerated resolution therapy for ptsds
Accelerated Resolution Therapy: good for fear-based trauma. Involves repeated prolonged imaginal exposure to the trauma memories (10-15 sessions). Repeated in vivo exposure to avoided situation in daily living
Dropout rates 30-40%
outline the phases of Eye Movement Desensitization Therapy
Eye Movement Desensitization Therapy: good for anger, guilt and shame. Decrease vividness of trauma images and introduce new positive beliefs
Dropout rate 18.9%
Past: maladaptive encoding/incomplete processing
Present: memory activated while using bilateral stimulation; body scanning
Future (goal of therapy): installation of positive beliefs related to target memory
Note; other ezposure-based therapies for PTSD
