Impression
Given nightmares after a significant traumatic event, am concerned about PTSD or Depression-anxiety. Would like to conduct full psychiatric assessment including MSE to further circumscribe the presentation and consider other differentials.

Ddx to consider:

  • Depression/ Major depression

Q

PTSD - Management

A

Management
No research supports the use of medication to prevent the onset of PTSD, nor to treat PTSD symptoms in the first 4-8 weeks as the majority will remit spontaneously.

PTSD
Non-pharmacological:
- trauma based CBT
- Eye movement desensitisation and reprocessing
- can offer non-trauma focussed psychotherapy to those not ready to engage with traumatic incident.

Pharmacological
May be used as adjunctive therapy, or in the instance of significant anxiety/depression symptoms warranting diagnoses, or in non-response to psychotherapy
1 - SSRI
2 - +/- atypical antipsychotic
3 - Atypical antidepressant (Mirtazepine)
