Utility of the diagnostic conceptualization
Although the controversy surrounding the distinction of CPTSD demands categorical clarity with respect to PTSD and borderline personality disorder as a means of resolution, the diagnosis has practical applications that should not limit its use in clinical formulation or treatment planning. Comorbid diagnoses do not prevent clinicians from diagnosing and treating patients who present with complicated manifestations of trauma.9 In fact, having overlapping diagnoses would highlight the array of patient presentations that can be seen in the posttraumatic condition. Furthermore, in the pursuit of individualized care approaches, the addition of CPTSD as a diagnostic conception would allow for more integrated treatment options using a multi-modular approach.10
The addition of CPTSD as a diagnosis is helpful in determining the etiology of a patient’s presentation and therefore formulating the most appropriate treatment plan. While the 2-pronged approach of psychopharmacology and therapy is the central dogma of psychiatric care, there are many specific options to consider for each. By viewing such patients through the lens of trauma as opposed to depression and anxiety, there is a clear shift in treatment that has the potential to make more lasting impacts and progress.11
CPTSD may coexist with PTSD, but it extends beyond it to include a pleomorphic symptom picture encompassing personality changes and a high risk for repeated harm. Failure to correctly classify a patient’s presentation as a response to repetitive, prolonged trauma may result in discrimination and inappropriate or ineffective treatment recommendations.
For a comparison of the diagnostic criteria of PTSD, CPTSD, and borderline personality disorder, see Table 112, Table 2,13,14, and Table 312.
Patients with CPTSD
One of the authors (NR) has cared for several similar individuals presenting for treatment with vague diagnoses of “chronic depression and anxiety” for years, sometimes with a speculative bipolar disorder diagnosis due to situational mood swings or reactivity, and a generally poor response to both medications and psychotherapy. These patients were frustrated because none of the diagnoses seemed to fully “fit” with their pattern of symptoms or subjective experience, and treatment seemed minimally helpful. Very often, their social history revealed a variety of adversities or traumatic events, such as childhood sexual or physical abuse, a home environment plagued by domestic violence, or being raised by one or both parents with their own history of trauma, or perhaps a personality or substance use disorder. Although many of these patients’ symptom profiles aligned only partially with “typical” PTSD, they were often better captured by CPTSD, with a focus on negative self-perception and impact on close relationships. Helping the patient “connect the dots” to create a more continuous narrative, and consequently reconceptualizing the diagnosis as a complex trauma disorder, has proven effective in a number of these cases, allowing the patient to make sense of their symptoms in the context of their personal history, reducing stigma, and allowing for different avenues with medication, therapy, and self-understanding. It can also help to validate the impact of a patient’s adverse experiences and encourage a patient to view their symptoms as an understandable or even once-adaptive response to traumatic stress, rather than a sign of personal weakness or defectiveness.
TREATMENT A trauma-focused approach
Once the treatment team considersMr. X’s significant childhood trauma and reconceptualizes his behaviors through this lens, treatment is adjusted accordingly. His significant reactivity, dissociative symptoms, social impairment, and repeated suicide attempts are better understood and have more significance through a trauma lens, which provides a better explanation than a primary mood disorder.
Therapeutic interventions in the hospital are tailored according to the treatment team’s new insight. Specific DBT skills are practiced, insight-oriented therapy and motivational interviewing are used, and Mr. X and his therapist begin to explore his trauma, both from his biological father and from his intense stressors experienced because of his medical issues.
Mr. X’s mother, who is very involved in his care, is provided with education on this conceptualization and given instruction on trauma-focused therapies in the outpatient setting. While Mr. X’s medication regimen is not changed significantly, for some patients, the reformulation from a primary mood or anxiety disorder to a trauma disorder might require a change in the pharmacotherapy regimen to address behavioral symptoms such as mood reactivity or issues with sleep.
OUTCOME Decreased intensity of suicidal thoughts
By the time of discharge, Mr. X has maintained safety, with no further outbursts, and subjectively reports feeling more understood and validated. Although chronic suicidal ideation can take months or years of treatment to resolve, at the time of discharge Mr. X reports a decreased intensity of these thoughts, and no acute suicidal ideation, plan, or intent. His discharge planning emphasizes ongoing work specifically related to coping with symptoms of traumatic stress, and the involvement of his main social support in facilitating this work.
The authors’ observations
As a caveat, it may be in some cases that chronic negative affect, dysphoria, and self-perception are better understood as a comorbid depressive disorder rather than subsumed into a PTSD/ CPTSD diagnosis. Also, because situational mood instability and impulsivity are often interpreted as bipolar disorder, a history of hypomania and mania should be ruled out. In Mr. X’s case, the diagnostic reformulation did not significantly impact pharmacotherapy because the target symptoms of mood instability, irritability, anxiety, and depression remained, despite the change in diagnosis.
Although the DSM-5 PTSD criteria effectively incorporate many CPTSD elements, we argue that this inclusivity comes at the expense of appreciating CPTSD as a qualitatively distinct condition, and we prefer ICD-11’s recognition of CPTSD as a separate diagnosis that incorporates PTSD criteria but extends the definition to include negative self-concept, affect dysregulation, and interpersonal difficulties.

Bottom Line
Consider a diagnosis of complex posttraumatic stress disorder (CPTSD) when providing care for patients with chronic depression and suicidality with a history of trauma or childhood adversity. This reformulation can allow clinicians to understand the contributing factors more holistically; align with the patient more effectively; appreciate past and present interpersonal, psychological, and psychosocial factors that may precipitate and perpetuate symptoms; and allow for treatment recommendations beyond those of mood and anxiety disorders.
