Concussion Talk Podcast

Concussion Talk Podcast

A podcast discussing concussions and all forms of traumatic brain injury, PCS (Persistent Concussion Symptoms, a.k.a. Post Concussion Syndrome), CTE (chronic traumatic encephalopathy), nutrition, work/school accommodations, exercise and more. I interview doctors, researchers, physiotherapists, and others in the field of brain injury.

I was severely brain injured in 2003 while cycling in Victoria, B.C. In a two-week induced coma and in hospital, including in patient rehab for months. I still have double vision and difficulty with my balance. I owe so much to my physiotherapists who helped me to walk and have been such a positive influence on my life. Also, swimming, walking and yoga (and pilates) and importantly, time, have meant continuous improvement.
I started Concussion Talk blog in 2010, wrote an e-book, Detour: Cycling, coma, and living with a brain injury, in 2014, and started Concussion Talk Podcast in 2015. I created, hosted and produced 164 episodes of Concussion Talk Podcast, put out many other podcasts beside.
I now co-host and produce Chronically with Lauren & Nick and produce Concussion in Women podcast.

PT, DPT, ATC, NCS
Lauren specializes in the rehabilitation of patients with complex chronic illnesses including: autonomic disorders (dysautonomia), patients with protracted recovery post concussion / mTBI (> 3 weeks), Long-COVID, and Functional Neurological Disorders (FND).

Lauren has advanced training in vision therapy. She is a Board-Certified Specialist in Neurologic PT, 2022 and earned a Vestibular Competency through Duke University in 2021. She was awarded the ANPT Clincial Excellence Award, 2026. Lauren is currently enrolled at Nova Southeastern University, pursuing her PhD in Health Science.

Lauren had the incredible opportunity to co-develop two novel intervention protocols for her patient populations: 1) The ZINC Protocol - integrating the neurological domains of concussion with a focus on Brain Body Integration (Primitive Reflex Integration), 2) The ADaPT protocol. A collaborative effort with Intermountain Health and the University of Utah, an objective, tailored, and measurable protocol for the treatment of dysautonomia. She co-authored the Preferred Practice Pattern for Intermountain Health for the Care of Patients with Chronic Autonomic Dysfunction.

Through a team based approach - including a FCOVD neuro-optometrist, medical team members, psychology, OT, PT, and SLP, the team offer state-of-the-art comprehensive treatment for the concussion and long-COVID populations. Lauren's favorite population to work with are those who have struggled chronically post concussion (>1year).

My primary goals: provider education, conducting and publishing research improve care for medically complex patients. I enjoy teaching and mentoring fellow staff members as well as students and have had the pleasure of onboarding fellow PTs into the world of complex chronic illness.

Through my work with concussions, I co-founded a tech company looking to close the education gap across the country. PhoenixConcussionRecovery.com is here to support providers treating in this complex medical space.

Providers are able to obtain CEUs for concussion educational content including: Early education, assessments across the concussion domains, working as a collaborative team, and integrating treatments across domains. We are also offering a Certification Program for our unique Primitive Reflex Integration Therapy Protocol for providers to immediately implement in their practice.

I am available for speaking engagements and enjoy presenting for a variety of audiences. My dream is to do a TEDTalk!
