Neurofeedback After Concussion or Traumatic Brain Injury: What You Should Know

Why concussion symptoms persist

A concussion or traumatic brain injury triggers a cascade of neurological events — disruption of ion gradients, metabolic changes, axonal injury — that physically damage brain tissue. But the symptoms that persist for weeks, months, or years after a concussion often reflect something different: ongoing dysregulation in the brain's electrical patterns, even after the physical injury has healed.

This is why many post-concussion patients continue to experience headaches, cognitive fog, irritability, sleep disturbance, and light sensitivity long after their imaging studies look normal. The tissue may have healed; the electrical patterns have not.

What QEEG reveals after TBI

A QEEG brain map is particularly valuable after concussion or TBI because it can show dysregulation that standard neuroimaging (MRI, CT) misses entirely. We routinely see excess slow-wave activity (theta) in frontal regions, disrupted connectivity between brain areas, and elevated high-beta activity that correlates with post-concussion anxiety and irritability.

This gives us a precise roadmap for treatment — targeting exactly the areas and patterns that are disrupted rather than applying a generic rehabilitation protocol.

Evidence and clinical experience

Multiple case series and controlled trials have demonstrated improvements in cognitive function, mood, headache frequency, and quality of life following neurofeedback in post-concussion patients. Some of our most gratifying outcomes at Helix involve clients who had been suffering for a year or more after a concussion and had largely resigned themselves to a 'new normal' — only to experience significant recovery through neurofeedback.
