CognitiveFX's website describes a Utah-based intensive treatment clinic specializing in evidence-based programs for concussion, post-concussion syndrome, POTS, and viral brain injury including Long COVID, post-treatment Lyme, and encephalitis. The flagship 5-day EPIC program uses fNCI (functional Neurocognitive Imaging) brain scans — which show brain function rather than just structure as standard scans do — to guide treatment. Specialized POTS treatment uses neurological retraining, vestibular recalibration, and CO₂ therapy in a 5-day intensive. CognitiveFX also offers fMRI-guided TMS for treatment-resistant depression, including a one-day accelerated TMS protocol. The clinic publishes treatment outcomes whitepapers, patient stories, and research, and uses a Good Fit Quiz to triage prospective patients.
