Integrating W.A.R.A.®, Brain-Switch 2.0®, and ReAttach® in the Treatment of Complex Trauma: An Exploratory Single-Case Report

Background: Individuals with complex trauma may continue to experience emotional distress, rumination, and maladaptive response patterns despite pharmacological treatment. Integrative interventions addressing affective responses, maladaptive patterns, and adaptive functioning warrant further clinical investigation.Case presentation: This report describes a 23-year-old woman diagnosed with complex trauma who her psychiatrist referred because she was not responding adequately to prescribed antidepressant and anti-anxiety medication. She received an eight-session intervention delivered in three phases: one session of Wiring Affect with ReAttach (W.A.R.A.®) on Day 1; one session of Brain-Switch 2.0® on Day 2 to address maladaptive brain patterns; and six subsequent ReAttach® sessions, emphasizing Cognitive Bias Modification (CBM) 3, followed by CBM 1 and CBM 2.Clinical observations: Following the Day 1 W.A.R.A.® session, the client reported a quieter mind, reduced rumination, greater calmness, and sleeping that night without sleeping medication. Brain-Switch 2.0® was administered on Day 2, which further enhanced her self-agency. Subsequent ReAttach® sessions integrated her sense of identity and improved boundary setting with her parents. At one-month post-therapy follow-up, the client reported improved management of rumination, greater emotional regulation, anxiety within normal ranges, preserved cognitive functioning despite ongoing family difficulties, and greater satisfaction with herself. Pre–post quantitative electroencephalography (qEEG) data showed changes in several recorded measures. The qEEG data indicated the absence of previous mental sluggishness, a clinically significant improvement in the trauma-related marker and emotional regulation within the normative range, and the absence of a depression-related marker.Conclusion: This case documents the clinical sequence and reported outcomes of an integrative intervention combining W.A.R.A.®, Brain-Switch 2.0®, and ReAttach®. The findings are preliminary. Because the intervention involved multiple components, the case cannot establish conclusive treatment efficacy, causality, or the mechanism underlying the observed changes.
