BRIEF GUIDE TO PTSD TREATMENT

Definitions of PTSD
 

1. ​Writer's Definition: A chronic dysregulation of the nervous system and cognition stemming from the emotional and perceptive experience of trauma. Symptoms of PTSD include heightened reactivity and arousal, intrusive and dissociative memories ("flashbacks"), nightmares, avoidance of stimuli associated with the event, negative conceptions of self related to the event (shame, guilt), and emotional dysregulation. While most of these symptoms are a part of the normal acute response to trauma, for a certain percentage of individuals these symptoms do not remit on their own and instead develop a chronic course, known as PTSD.

   1. Risk factors for developing PTSD following a traumatic experience include genetic predisposition, prior trauma, childhood adversity, low post-traumatic social support, and concurrent life stressors. It's development is also moderated by interpersonal attachment styles, socio-cultural and personal values, and perception of the trauma’s relevance to identity. 
       

2. DSM-5 Definition (abridged):

   1. Exposure to actual or threatened death, serious injury, or sexual violence

   2. Presence of one (or more) intrusion symptoms associated with the
      traumatic event(s), beginning after the traumatic event(s) occurred

   3. Persistent avoidance of stimuli associated with the traumatic event(s), beginning after
      the traumatic event(s) occurred

   4. Negative alterations in cognitions and mood associated with the traumatic event(s),
      beginning or worsening after the traumatic event(s) occurred

   5. Marked alterations in arousal and reactivity associated with the traumatic event(s), be-
      ginning or worsening after the traumatic event(s) occurred

   6. Duration of the disturbance (Criteria B, C, D, and E) is more than 1 month

      [Note: This definition is highly abridged due to the significant length of the DSM-5 criteria for PTSD. For the full criteria, please see: https://www.ptsd.va.gov/professional/treat/essentials/dsm5_ptsd.asp]
       

3. ICD-10 Definition [abridged]: An anxiety disorder precipitated by an experience of intense fear or horror while exposed to a traumatic (especially life-threatening) event. The disorder is characterized by intrusive recurring thoughts or images of the traumatic event; avoidance of anything associated with the event; a state of hyperarousal and diminished emotional responsiveness. These symptoms are present for at least one month and the disorder is usually long-term. Symptoms interfere with day-to-day living and include reliving the event in nightmares or flashbacks; avoiding people, places, and things connected to the event; feeling alone and losing interest in daily activities; and having trouble concentrating and sleeping.

Mechanism of PTSD

​​

1. Experience of Trauma: Trauma is the immediate and negative emotional response to a severely distressing event, such as significant loss, violence, bodily harm, threatened death or injury, major accidents, natural disasters, or witnessing death or harm. Psychological shock (an Acute Stress Reaction) is normal acute response to trauma, and often entails heightened reactivity and arousal, hypervigilance, avoidance of related stimuli, negative mood, and emotional dysregulation. For the majority of individuals these acute symptoms resolve without clinical intervention within days or weeks. For some individuals and for some traumatic experiences, these symptoms do not remit and instead develop a chronic course.  
    

2. Maladaptive Processing of Experience: Following the experience of trauma, multiple interconnecting variables influence the likelihood of developing PTSD. Social support immediately following a traumatic experience serves as a significant protective factor, as does the affected individual’s perceived ability to speak openly about and process the experience. Similarly, low-stress and accommodating environments, higher socio-economic standing, prompt therapeutic and psychiatric support, identification with others who possess a shared experience, and integration with spiritual practices all also serve as protective factors from the development of PTSD.
   
   Conversely, if following a traumatic experience an individual is unsupported or abandoned by their community, receives explicit or implicit communication from others to not discuss the trauma, is personally blamed for the experience, is unable to allocate time to process, grieve, or emotionally regulate due to high-stress environments or socioeconomic barriers, is unable to or does not access professional support, and/or perceives that they are alone and isolated in their experience, the likelihood of the traumatic experience being maladaptively processed and developing into PTSD increases. 
   
    

3. Emotional and cognitive dysregulation: As a result of the maladaptive processing and integration of the traumatic experience, severe processes occur:

   1. Acute trauma symptoms do not remit or respond to the standard extinction process (in which conditioned fear gradually diminishes through the absence of ongoing threats). As such, cue-triggered distress, hypervigilance, startle responses, and avoidance are maintained rather than fading in response to the present-day situation in which the threat is absent. 

   2. Negative appraisals and narratives develop surrounding the trauma and its aftermath, furthering emotional experiences of shame, horror, and/or guilt. While negative appraisals are a normal acute response to trauma, the chronic and non-remitting course of symptoms in PTSD often further exacerbate these negative appraisals and develop them into complex negative narratives about self and the world.

   3. Avoidance and counterproductive coping continue and develop. Avoidance, as an acute trauma response, serves an evolutionary protective mechanism of preventing immediate further harm. For example, if an hunter-gatherer ancestor of ours was attacked by a bear and survived, the immediate avoidance of any related stimuli (caves, where the attack occurred, food sources that bears frequent) served to increase the individual's chance of survival. Over time, as the individual healed and was able to process the series of events that lead to the bear attack, the avoidance and other acute trauma symptoms would fade. With PTSD, as acute symptoms and avoidance fail to diminish and continue on a chronic course, the avoidance ceases to be productive and instead results in a restricted or narrowed life, thought suppression, rumination, excessive self-protective behaviors, substance use, dissociation, and/or emotional numbing. These behavioral responses can often isolate the individual and impair social connections, further impairing one of the primary risk factors for the development and maintenance of PTSD. 

   4. Physiological hyperarousal and sleep disruptions prevent emotional and physical rest, increase fatigue, and increase the risk of secondary depression. As the acute trauma symptoms do not remit, the sympathetic nervous system remains frequently or near-constantly activated and prevents the individual from shifting to a resting-state (parasympathetic activation). Combined with insomnia and trauma-related nightmares, the individual is at a much greater risk of physical and psychological fatigue, further compounding difficulties with coping or further processing the traumatic experience. Similarly, the somatically unpleasant and often painful experience of sympathetic (fight/flight) activation can lead to excessive introspective awareness and processing, manifesting as "bracing" against anxiety/fear, avoidance of bodily sensations, and/or preoccupation with somatic experiences.

Treatments for PTSD

Note: PTSD treatment should generally not be self-applied. This guide does detail basic somatic and coping techniques that can be helpful in reducing immediate distress, but these are surface-level supports and differ from treatment targeting the core symptoms and mechanisms of PTSD. Again, treating PTSD should be done only with a trained and experienced therapist or psychologist.

This differs slightly from OCD (see OCD Treatment Guide), in which working with a therapist is highly beneficial and recommended and, simultaneously, many components of treatment can be self-applied. Even in working with a therapist, the majority of OCD treatment occurs outside of session, throughout the week, in applying the treatment as obsessions and compulsions arise. This is not the case for treatment of PTSD, in which the majority of actual treatment is applied within session.

 

1. Prolonged Exposure (PE): A process of psychoeducation, breathing retraining, developing a graded hierarchy of in vivo exposure to (objectively safe) avoided triggers, and repeated imaginal exposure ("revisiting") to the trauma memory followed by processing. Later sessions focus on the most distressing "hot spots". 
    

   1. Efficacy: Strong research support, with the therapy specifically targeting symptoms of avoidance, cue-triggered fear ("trauma triggers"), intrusive thoughts, and maladaptive beliefs.
      
      PE has been a longstanding first-line treatment for PTSD. While PE is research-supported as effective, it is also a fundamentally uncomfortable process, resulting in higher dropout (therapy discontinuation) rates as compared to EMDR and CPT. PE is recommended as a first-line treatments for PTSD by all four of the major institutes conducting research and publication on PTSD. [The four instittues are the American Psychiatric Association (APA), Veterans Affairs/Department of Defense (VA/DoD), International Society for Traumatic Stress Studies (ISTSS), and National Institute for Health and Care Excellence (NICE].
       

2. Eye Movement Desensitization & Reprocessing (EMDR): An eight-phase protocol (history, preparation, assessment, desensitization, installation, body scan, closure, reevaluation). During desensitization the individual holds a target memory with its distressing image, negative cognition and body sensation in their mind while doing sets of bilateral stimulation (eye movements, taps or tones). 
    

   1. Efficacy: Strong research support, with the therapy specifically targeting symptoms of intrusive trauma-linked memories, maladaptive and negative self-beliefs, and somatic reactivity and arousal. 
      
      EMDR is recommended as a first-line treatment for PTSD by three of the four major institutes (all except the APA, with the APA's 2025 decision to re-classify it as a second-tier treatment receiving significant formal criticism for relying on outdated methodology and reviews). 
       

3. Cognitive Processing Therapy (CPT): A structured cognitive therapy that identifies "stuck points" (beliefs about why the trauma happened and what it means) and examines them through Socratic dialogue and graded worksheets, then works through themes of safety, trust, power/control, esteem and intimacy. This therapy also often, but not necessarily, utilizes written therapy narratives. 
    

   1. Efficacy: Strong research support, with this therapy specifically targeting symptoms of negative thoughts and mood, self-blame (guilt and shame), and beliefs around ongoing danger. Intrusive memories and avoidance also generally decrease as a secondary effect the changing beliefs. A major VA trial found CPT to be slightly less effective than Prolonged Exposure (PE), though only marginally, and that CPT had a lower dropout rate as compared to PE. 
      
      CPT is recommended as a first-line treatment for PTSD by all four of the major institutes. 
       

4. Cognitive Therapy for PTSD (CT-PTSD): A cognitive therapy that aims to reduce the sense of current threat by changing negative beliefs, updating trauma memories, and dropping unhelpful coping strategies. Techniques include identifying "hot spots" in the memory and linking them to updated information, discriminating "then" from "now" triggers, site visits, and reclaiming-your-life assignments

   1. Efficacy: Good research support, with the therapy specifically targeting maladaptive beliefs, intrusive memories, and avoidance and counterproductive coping behaviors. Research found that improvements in the maladaptive beliefs preceded later reductions in other symptoms, even if those other symptoms were not directly targeted by the therapy. 
      
      CT-PTSD is recommended as a first-line treatment for PTSD by three of the four major institutes (with the exception of the VA/DoD). 
       

5. Internal Family Systems (IFS): A model of the mind as a system of "parts": protective managers that prevent pain, reactive firefighters that douse it (for example with substances or dissociation), and exiles that hold traumatic pain and burdens. Therapy helps the client "unblend" from parts, access a compassionate core Self, and help exiled parts be witnessed and "unburdened.
    

   1. Efficacy: Poor research support as of present, with the therapy specifically targeting shame, self-criticism, counterproductive coping behaviors, and internal self-organization. The therapy's poor research support stems from relevant studies being either small in scope or of a limited methodology. While I personally value and utilize Parts-Work/IFS frequently for both the treatment of PTSD and other mental illness, the research findings are thus far not significant or substantial enough for IFS to be recommended as a first-line treatment. As a personal clinical opinion, I've found that it works well as a supplementary treatment and framing method when utilized alongside the application of a first-line treatment for PTSD. 
      
      IFS is not recommended by any of the four major institutes as a first-line or second-tier treatment for PTSD, and for a therapist to offer IFS alone as a treatment for PTSD is not currently consistent with best practices based on research. This may change as larger and more comprehensive research is undertaken and published, though as of present it's efficacy is uncertain and anecdotal reports are likely slightly biased by IFS' "pop psychology" status. 
       

6. Somatic Experiencing: A body-focused therapy that builds awareness of internal physical sensations, which the model treats as carriers of traumatic memory. Techniques include tracking sensation, "titration" (small doses of activation), "pendulation" between activation and resourced states, and allowing completion of thwarted defensive responses.
    

   1. Efficacy: Poor research support as of present, with the therapy specifically targeting symptoms of persistent stress activation, interoceptive avoidance, and sympathetic threat responses.  
      
      Somatic Experiencing is not recommended by any of the four major institutes as a first-line or second-tier treatment for PTSD. As with IFS, it can still serve as a useful and effective adjunct alongside a first-line treatment.
