PTSD (“TRAP”)
• Traumatic event:
• Re-experiencing or re-living the trauma
• Avoidance and Numbing
• Physical arousal/tension
![Page 4: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/4.jpg)

Re-experiencing the trauma
– recurrent & intrusive recollections of the event, including images, thoughts or perceptions
– recurrent nightmares– acting or feeling as if the trauma were recurring
• dissociative flashbacks• sense of reliving the experience• illusions• hallucinations
![Page 6: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/6.jpg)
Re-experiencing the trauma
With exposure to internal or external cues that symbolise or resemble an aspect of the traumatic event:
– physiological reactivity – intense psychological distress
![Page 7: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/7.jpg)
Avoidance and Numbing
Avoid reminders of trauma • thoughts, feeling, conversations• activities, places, people• unable to recall key aspects
![Page 8: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/8.jpg)
Avoidance and Numbing
Emotional withdrawal: • reduced involvement in sig. activities • sense of detachment from others• restricted range of affect• sense of foreshortened future
![Page 9: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/9.jpg)
Avoidance and Numbing
The patient is in survival mode – Avoidance: a way to keep away from
further danger which still feels present– The individual may feel safe but is
isolated and withdrawn from life
(Jan Ewing workshop June 2008)
![Page 10: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/10.jpg)
Physical arousal/tension
– hypervigilant (“on guard”); – exaggerated startle response;– irritability & angry outbursts; – poor concentration;– difficulty falling or staying asleep
![Page 11: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/11.jpg)
Physical arousal/tension
– Keeps the patient alert & prepared for the presence of danger
• know where the Exits are• sit with their back to the wall• need to be able to see and monitor everything
– “The threat detector” is so strong, the slightest “whiff” of a threat results in hyperarousal (Jan Ewing 2008)

PTSD Diagnosis (DSM-IV)
– Duration > one month– Associated with:
• significant distress or • impairment in functioning

Complex PTSD
• Genesis: CSA• PTSD symptoms +
– damage to attachment & self-systems– serious difficulties with affect regulation
& self-soothing– more likely to use dissociation as a
survival strategy + substance abuse

What treatments work best?
![Page 19: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/19.jpg)
Traditional SUD treatment
• Patients with and without PTSD improve substance use, mental & physical health
• PTSD group:– poorer physical & mental health– poorer occupational functioning– residual PTSD symptoms which
often trigger relapse– PTSD needs focussed treatment

Relationship between SUD & PTSD
• Substance used to modify PTSD symptoms (“self medication”)
• As dependence develops, physiologic arousal from substance withdrawal exacerbates PTSD symptoms
• This exacerbation contributes to relapse• Substance using lifestyle: risk of
trauma exposure• Both disorders maintain/exacerbate the
other

![Page 49: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/49.jpg)
Recommendations
– Screen for PTSD, depression, suicidality– Remember avoidance part of disorder– If you don’t ask, they may not tell you– Normalise the patient’s response to the
trauma: validates their feelings & experience
– Awareness of triggers may facilitate best management eg male case manager

PTSD symptoms often increase during withdrawal
– No longer masked by D & A use– Autonomic hyperactivity in withdrawal
exacerbates hyperarousal symptoms– Important to educate patients about
likely increase in symptoms– Provide tools/strategies to manage
symptoms

Strategies to manage PTSD symptoms
• Medication for anxiety
• Progressive muscle relaxation
• Breathing techniques
• Visualisation and imagery
• Grounding e.g. mindfulness

Treatment Phases
Establish therapeutic alliance/trust: – first step in any treatment– may take years– may be all you can do– may be impossible with some patients
where the patient’s transference is unmanageable

Treatment PTSD & SUD– Gold standard PTSD: exposure– Traditionally considered inappropriate
with SUD: • fear >emotions trigger relapse• impaired cognitions SUD impair
ability for imaginal exposure• belief extended recovery needed

COPE v. IICOPE v. II
• NDARC conducted a randomised controlled trial of a modified version of CTPSD: Concurrent Treatment with Prolonged Exposure version II (COPE v2; Mills et al 2007).
• Target population: Individuals with any drug use disorder and multiple sources of trauma
• Sessions: 13 sessions with a clinical psychologist• Format: Individual• Program: CBT with imaginal and in vivo exposure
The first randomised controlled trial of exposure therapy among individuals with SUDs

Across the 9 mth follow-up period:
– Both groups evidenced improvements in their • Substance use• Severity of dependence• PTSD symptoms• Depression• Anxiety • General mental health
ConclusionConclusion
THEY DID NOT GET WORSE!
![Page 64: Lost in a Moment in Time: PTSD and Substance Use Disorders Herbert Street Clinic Detoxification Unit, RNSH Dr Glenys Dore. Robin Murray. April 2010.](https://reader030.fdocuments.in/reader030/viewer/2022032518/56649cce5503460f94999091/html5/thumbnails/64.jpg)
Participants randomised to COPE demonstrated:– significantly greater improvements in PTSD
symptoms – particularly avoidance and hyperarousal symptoms
These findings provide evidence in support of
treating PTSD among people with SUDs using COPE (Mills et al., 2007).

Questions for discussion
PTSD treatment really helps• How & where can we access it
for our patients?• Should all D & A workers be
trained in trauma counselling?• How best to support staff when
dealing with trauma issues?
