Historical Perspectives• 1666, Great Fire of London - Samuel Pepys’ diaries, trauma-related
nightmares, “..much terrified in the nights nowdays with dreams of fire and falling down of houses” (1667)
• Debate for many years about whether symptoms were organic or psychological in origin:
- 19th Century - “railway spine”
- World War I - “shell shock”
- World War II - “concentration camp syndrome”
• War in Vietnam – large numbers of sufferers showing similar psychological reactions to overwhelming stress
• PTSD officially defined DSM-III, 1980
Kerry Young, CNWL NHS Foundation Trust 2014

What is Acute Stress Disorder ?
• Remember most people will have PTSD symptoms in month after trauma (94% after rape in one study) – it is ‘normal’
• ASD refers to a more dissociative version of PTSD that occurs within 2-30 days of trauma
• Rates 6-33% of those involved in trauma
Kerry Young, CNWL NHS Foundation Trust 2014
What is Acute Stress Disorder ?
• All criteria as for PTSD plus
• Dissociative Sx:– Numb, detached, emotionally unresponsive– Reduced awareness of surroundings– De-realization (your environment seems not real)– De-personalization (your thoughts/emotions don’t seem
real/to come from you)– Dissociative Amnesia (can’t remember significant aspects of
trauma in absence of TBI)
• Need 3 or moreKerry Young, CNWL NHS
Foundation Trust 2014
What is Acute Stress Disorder ?
• Highly predictive of subsequent PTSD
• Need:- Psychiatric evaluation- Hospitalization if risk- Information- CBT- Medication
Kerry Young, CNWL NHS Foundation Trust 2014
How to identify it
• If someone recently involved in a trauma
• Complaining of any of the PTSD Sx
• Give them Trauma Screening Questionnaire (Brewin et al., 2002)
• 6 or more positive responses indicate at risk of having PTSD diagnosis
Kerry Young, CNWL NHS Foundation Trust 2014
What to do if they look like they might have PTSD
• Refer to appropriate mental health service i.e.
- IAPT
- student counselling service if offer evidence based
PTSD treatments (CBT or EMDR)
Kerry Young, CNWL NHS Foundation Trust 2014
What to do if they look like they might have PTSD
• In meantime, leaflets a good idea
• Student counselling service may have PTSD information leaflet
• Or suggest obtain PTSD psycho-educational material online;
- Royal College of Psychiatry
http://www.rcpsych.ac.uk/healthadvice/problemsdisorders/posttraumaticstressdisorder.aspx
- NICE
http://www.nice.org.uk/nicemedia/live/10966/29782/29782.pdf
Kerry Young, CNWL NHS Foundation Trust 2014
NICE Guidelines – early intervention
• Consider watchful waiting when symptoms are mild and have been present for less than 4 weeks after a trauma
• Arrange a follow up contact within 1 month• For individuals who have experienced a
traumatic event, do not routinely offer brief single session interventions (debriefing)
Kerry Young, CNWL NHS Foundation Trust 2014
NICE Guidelines – after 1 month
• All PTSD sufferers should be offered a course of tfCBT (trauma-focused cognitive behavioural therapy) or EMDR (Eye Movement Desensitization and Reprocessing) regardless of the time since the trauma
Kerry Young, CNWL NHS Foundation Trust 2014
What is tfCBT ?
• Based on the understanding that trauma memories aren’t properly integrated into memory
• Need to get the patient to ‘re-process’ the memory so it can be integrated and will stop popping into their heads when they don’t want it to
Kerry Young, CNWL NHS Foundation Trust 2014
Kerry Young, May 2011
Duvet and CupboardImagine that memory is a little bit like a linen cupboard: lovely and organized, with towels on one shelf, sheets andpillow cases on another and, finally, duvet covers andblankets on the last shelf.
When you are involved in a trauma, it is as if someone runsat you with a huge duvet in their arms, screaming “PUTTHAT IN THE CUPBOARD RIGHT NOW!” You take theduvet, stuff it in, jam the door shut and walk away. As youdo so, the cupboard door opens and the duvet flops out.The person screams at you again, their face right up againstyour face, “PUT IT BACK IN, PUT IT BACK IN NOW!” You grab it off the floor,bundle it back in, jam the door shut and walk away. Again the door opens andagain the duvet spills out onto the floor. Growing increasingly agitated, theperson screams, “PUT IT BACK IN, PUT IT BACK IN, PUT IT BACK IN!”
Kerry Young, May 2011
Duvet and Cupboard cont.In the end, you find that the only way to keep the duvet in the cupboard is to standwith your back against the door. But you can’t do that forever and, anyway, you willneed to go into the cupboard eventually to get other things out. When you do, theduvet will tumble out again.
What is tfCBT ?
• Involves talking about the traumatic event in a lot of detail, including all five senses, emotions and thoughts
• Worst moments of the trauma narrative are re-scripted with new/corrective information so that the memory can be nicely packed away
• 10-12 sessions on average for one-off trauma

Medication and PTSD
• NICE say medication a second-line treatment ONLY to be used if tfCBT/EMDR failed/not indicated
• Recommend paroxetine and mirtazepine (NICE Evidence Update 2013 – fluoxetine and venlafaxine might also be useful)
• Worth considering if co-morbid depression
• No robust evidence for mood stabilizers (e.g. carbamazepine) or benzodiazepines (e.g.clonazepam)
• Review Jonathon Bisson (2007) need doses at higher end of therapeutic range and delay decisions about usefulness
Kerry Young, CNWL NHS Foundation Trust 2014
What else to watch out for
• Co-morbidity with substance misuse, depression, panic
• Increased rates of suicide
• NB may not want to tell you what happened (especially if sexual assault/rape)
Kerry Young, CNWL NHS Foundation Trust 2014
Take home message
• PTSD is quite likely after inter-personal trauma
• PTSD is very treatable (you can expect remission from diagnosis after 10-12 sessions)
• PTSD needs a psychological treatment (tfCBT or EMDR)
