In this video, David Brimacombe explains why, after a concussion, the brain often resists positive change. He argues that the brain’s primary mission is survival—not personal well‑being—so it treats new, healthier thoughts and actions as potential threats. This safety‑first wiring can cause a person with post‑concussion syndrome (PCS) to experience fear, anxiety, or resistance when attempting recovery‑focused behaviors such as cognitive exercises, physical activity, or mindset shifts. Brimacombe links this phenomenon to the nervous system’s protective responses and suggests that understanding the brain’s bias toward safety is essential for designing effective PCS rehabilitation strategies.
