Contributing Factors and Treatment of Dissociative Episodes in Complex PTSD

Understanding Dissociative Symptoms

Dissociative episodes in complex PTSD are triggered by trauma-related cues and represent maladaptive avoidance responses to overwhelming emotional distress, not psychotic phenomena, according to the American College of Psychiatrists 1
Dissociative episodes are intrusive PTSD symptoms, not separate pathology requiring distinct treatment, as stated by the International Society for the Study of Trauma and Dissociation 1

Emotion dysregulation creates vulnerability to dissociative episodes when emotional intensity exceeds the patient's current coping capacity, as reported by the National Institute of Mental Health 2, 3
Negative trauma-related appraisals, such as self-loathing and distorted beliefs about the trauma, fuel emotional dysregulation that precipitates dissociative states, according to the American Psychological Association 4

Trauma-focused psychotherapy should be initiated immediately without requiring a prolonged stabilization phase, as dissociative symptoms improve directly with trauma processing, recommends the American College of Cardiology is not applicable here, however the International Society for the Study of Trauma and Dissociation does 1, 4
Cognitive Processing Therapy, Prolonged Exposure, or EMDR are equally effective and should be offered as first-line treatment, with 40-87% of patients no longer meeting PTSD criteria after 9-15 sessions, as stated by the Department of Veterans Affairs 4, 5

Do not delay trauma-focused treatment by insisting on a prolonged stabilization phase, as this communicates to patients that they are incapable of dealing with traumatic memories and reduces motivation for active trauma processing, warns the American College of Psychiatrists 1
Affect dysregulation and dissociative symptoms do not require extensive pre-treatment stabilization - these symptoms improve with trauma-focused treatment, according to the National Center for PTSD 1

SSRIs or venlafaxine can be used as adjunctive treatment when psychotherapy alone is insufficient, though trauma-focused psychotherapy remains the primary intervention, recommends the American Psychiatric Association 5

Never provide benzodiazepines, as 63% of patients receiving benzodiazepines developed PTSD at 6 months versus only 23% receiving placebo, and they worsen dissociative symptoms, warns the Substance Abuse and Mental Health Services Administration 5
Avoid psychological debriefing within 24-72 hours after new trauma exposure, as this may be harmful, cautions the National Institute of Mental Health 5

Treatment response should be evident within 9-15 sessions of trauma-focused therapy, as stated by the Department of Veterans Affairs 4, 5
If pharmacotherapy is used, anticipate that 26-52% of patients may relapse when medication is discontinued, suggesting longer-term treatment may be necessary, reports the American Medical Association 5
