Post-concussion rehabilitation has matured considerably. Functional neurologists and allied clinicians now routinely identify vestibular, oculomotor, and autonomic dysfunction, match findings to evidence-based interventions, and deliver structured rehabilitation with clinical precision. Yet a subset of patients continues to confound even the most experienced practitioners: those who respond within a session, lose those gains before the next visit, and repeat the cycle across weeks or months. When the clinical picture is accurate and the protocol is sound, the question becomes what else is governing recovery.

This course introduces a compelling and clinically actionable answer. Matt Tolstoy DACM, LAc, LP-C presents the centrally sensitized threat-appraisal state as a missing differential in the post-concussion population. The central autonomic network, comprising the insula, anterior cingulate cortex, amygdala, hypothalamus, and periaqueductal gray, does not only compute threat. It also gates autonomic tone and modulates neuroplasticity. When a patient's nervous system holds a high-threat baseline, whether shaped by prior psychological history, the injury event itself, or the cumulative experience of failed recovery, rehabilitative exposure is processed as one more input to defend against rather than integrate. Intrasession gains are real. Consolidation is suppressed. The protocol is not failing. Upstream threat physiology is.

This course is designed for functional neurologists, chiropractic neurologists, physical therapists, occupational therapists, and any licensed clinician working with complex or non-responsive post-concussion cases. It is particularly valuable for practitioners who have already developed strong neurorehabilitation skills and are encountering the clinical ceiling that unaddressed threat physiology creates.
