Year: 2026
Type: article
Study design: Case Report
Abstract: Background: Traumatic brain injury (TBI) with post-traumatic stress disorder (PTSD) is treatment-resistant, with conventional psychotherapy showing limited efficacy due to neurocognitive impairments. Case Summary: We report two patients with severe TBI and psychiatric comorbidities treated with Prism neurofeedback. Case 1: 44-year-old female, 35 years post-childhood TBI, with agoraphobia and hyperacusis, achieved 42% PTSD reduction and substantial functional gains (social reintegration, independent driving) sustained through 4-month follow-up. Case 2: 40-year-old male, 3.5 years post-adult TBI with bipolar II disorder and severe PTSD (PCL-5 = 62), achieved 90% PTSD reduction with complete remission sustained at 1-month follow-up, enabling return to work and family system transformation. Both patients developed personalized regulatory strategies and maintained gains without relapse. Conclusions: Prism neurofeedback demonstrates clinically meaningful outcomes in severe TBI-PTSD where traditional psychotherapy shows limited efficacy. The intervention's circumvention of cognitive processing demands may explain the favorable outcomes. Controlled trials are warranted.
