Conversion Disorder (Functional Neurological Symptom Disorder) in Primary Care Mental Health

This case report describes the application of a dialectical behavioral therapy–informed psychotherapy approach to treating conversion disorder (functional neurological symptom disorder) with motor dysfunction in a Veterans Administration Health System Primary Care–Mental Health Integration Clinic. “Jane,” a 30-year-old veteran, was diagnosed with conversion disorder, major depressive disorder (MDD), and posttraumatic stress disorder (PTSD). She completed 25 sessions of treatment focused on improving emotion regulation and interpersonal skills over an 8-month period. At the end of treatment, Jane demonstrated improved motor ability and clinically significant improvements in her reported symptoms of MDD (per the Patient Health Questionnaire–9) and PTSD (per the PTSD Checklist–Civilian Version). This case report supports the conceptualization of conversion disorder as a function of emotion dysregulation and the application of a dialectical behavior therapy–informed treatment approach
