The myth that held people back
A landmark piece of journalism that put the “just rest” myth under a spotlight — and why it matters for everyone experiencing PCS.
“How We Got Concussions So Wrong”
Written by science journalist Isobel Whitcomb after her own concussion experience, this article exposes the pervasive myth that rest is the primary treatment for concussion — and how that myth has actively harmed millions of people. Whitcomb documents her months of unnecessary suffering, the emerging science of active rehabilitation, and why the medical system has been slow to change.

“It’s a huge myth. It’s so pervasive; it’s actively damaging people’s recovery.”

This is exactly what BRN Concussion Bootcamp addresses.
The science is clear: active rehabilitation — not rest — is what helps the brain recalibrate after concussion. BRN’s Concussion Bootcamp was built on this evidence. Whether you’re a person who has been told “just rest” or a clinician looking for a better answer for your people, the Bootcamp provides the strategies, the structure, and the support to Go Forward.
What the evidence shows
The science supporting active rehabilitation for PCS is robust and growing. These are the key studies that have changed how we understand and treat concussion.
Early Activity After Concussion Improves Recovery
Grool AM, et al. JAMA. 2016;316(23):2504–2514.
Among 2,413 young athletes, those who resumed activity within the first week after concussion — even with some symptoms — had significantly better outcomes. Only 24.6% still had symptoms at 28 days, compared to 43.5% in those who followed strict rest protocols.

Lumba-Brown A, et al. JAMA Network Open. 2018;1(7):e184551.
More than half of concussion people leave the doctor's office without actionable, evidence-based information or specialist referrals. Of those who did receive follow-up care, only 15% ever visited a clinic specializing in brain injuries.
View sourceConsensus Statement on Concussion in Sport (6th Edition)
Patricios JS, et al. Br J Sports Med. 2023;57(11):695–711.
The international expert panel now explicitly recommends "active rehabilitation" over total rest. The consensus discourages prolonged cocooning and supports graded return to activity, aerobic exercise, and multidisciplinary care for persisting symptoms.

Meehan WP, et al. Pediatrics. 2022;150(5):e2022056835.
Children who engaged in moderate screen time (2–7 hours/day) in the first week after concussion had significantly better outcomes at one month than those who restricted screens to under 2 hours. Cognitive engagement — not deprivation — supports recovery.

Majerske CW, et al. J Head Trauma Rehabil. 2009;24(4):269–279.
In 16 children and teens with PCS lasting 4+ weeks, a structured daily treadmill and sport-drill protocol produced complete recovery within 5 weeks on average — demonstrating that graded exercise is effective even in chronic PCS cases.

Zetterberg H, Blennow K. Neurochemistry International. 2021;148:105–116.
Recovery from concussion is not about repairing damaged neurons — it's about the brain finding new signal pathways. This recalibration requires active engagement, not rest. The brain rewires itself through use, not through deprivation.

Every component of our program — graded aerobic exercise, ANS regulation, vestibular rehabilitation, cognitive engagement — is grounded in the research above. For people who haven’t responded to standard care, and for clinicians who need a better answer, the Bootcamp is the next step.
People who went forward
Recovery from PCS is possible. These are the stories of people and clinicians who found a path forward — and what made the difference.
“I was told to rest. I rested for six months and got worse. When I finally found BRN, I learned that my nervous system was stuck — not broken. The Bootcamp gave me strategies I could actually use. Three months later I was back in the classroom.”
“Every doctor told me there was nothing more they could do. I had accepted that this was just my life now. BRN showed me that the brain can keep healing — it just needs the right conditions. I had no idea what those conditions were until Bootcamp.”
“I referred a person to BRN after she had seen six specialists with no improvement. The Bootcamp gave her — and me — a framework I hadn't encountered in my training. She made more progress in six weeks than in the previous two years.”
The essentials, explained simply
New to PCS or the ANS? These quick-reference cards cover the core concepts you need to understand your condition and your recovery.
What is a concussion?
A concussion is a traumatic brain injury caused by a bump, blow, or jolt to the head — or a hit to the body that causes the brain to move rapidly inside the skull. It disrupts normal brain function and triggers a neurochemical cascade that can take weeks to resolve.
What is PCS?
Persisting Concussion Symptoms (PCS) is the term for concussion symptoms that last beyond the expected recovery window — typically more than 4 weeks in adults. About 1 in 5 concussion people develop PCS. It is not a sign of weakness or psychological fragility. It is a neurological condition.
What is the ANS?
The Autonomic Nervous System (ANS) controls involuntary body functions — heart rate, breathing, digestion, sleep, and the stress response. After a concussion, the ANS can become dysregulated, locking the body in a state of chronic activation that perpetuates every PCS symptom.
What is CARF accreditation?
CARF International (Commission on Accreditation of Rehabilitation Facilities) is the gold standard for rehabilitation quality. CARF accreditation means a program has been independently reviewed against rigorous standards for clinical outcomes, patient safety, and evidence-based practice. BRN was the first concussion rehab program in the world to earn it.
Why does sleep matter so much in PCS recovery?
Sleep is when the brain consolidates memory, clears metabolic waste, and repairs itself. After a concussion, sleep architecture is often disrupted — meaning even if you're in bed for 8 hours, you may not be getting restorative sleep. Poor sleep amplifies every PCS symptom and slows recovery. Addressing sleep is a core part of BRN's program.
What is vestibular rehabilitation?
The vestibular system — located in the inner ear — controls balance and spatial orientation. Concussion frequently disrupts vestibular function, causing dizziness, balance problems, and motion sensitivity. Vestibular rehabilitation uses specific exercises to retrain the vestibular system and reduce these symptoms.

Deeper dives into the topics that matter most for PCS recovery — written for people, families, and professionals.
What Is Persisting Concussion Syndrome?
About 1 in 5 people who sustain a concussion develop symptoms that last beyond the expected recovery window. This article explains what PCS is, why it happens, and why it's so often misunderstood — even by the medical community.
The Autonomic Nervous System and Concussion
The ANS controls your heart rate, breathing, digestion, sleep, and stress response. After a concussion, it can get locked in a state of chronic activation — and that activation drives every symptom you're experiencing. Here's how it works and why it matters.
Why Dizziness and Vision Problems Persist After Concussion
Vestibular and visual symptoms — dizziness, balance problems, motion sensitivity, blurred vision — are among the most disabling aspects of PCS. This article explains the neurological basis of these symptoms and what targeted rehabilitation looks like.
Sleep After Concussion: Why It's So Hard and What to Do
Sleep disruption is both a symptom and a driver of PCS. Without restorative sleep, the brain cannot heal — and every other symptom gets worse. This article covers the science of post-concussion sleep disruption and evidence-based strategies for improving it.
Why Exercise Is One of the Best Treatments for PCS
For years, rest was the standard advice after concussion. The evidence has shifted dramatically. Graded aerobic exercise — done correctly — is now one of the most powerful tools in PCS recovery. Here's what the research shows and how it works.
Understanding Post-Concussion Brain Fog
Brain fog — difficulty concentrating, word-finding problems, slowed thinking, memory lapses — is one of the most frustrating PCS symptoms. This article explains what's actually happening neurologically and what cognitive rehabilitation can do about it.
Supporting a Loved One with PCS: A Guide for Families
Living with someone who has PCS is hard — and most families feel completely unprepared. This guide explains what your loved one is experiencing, why they may seem different, and how you can support their recovery without burning yourself out.
The Standard of Care for PCS: What Clinicians Need to Know
Most PCS people are not receiving evidence-based care. This article outlines what the current evidence supports, why ANS dysregulation is the missing piece in most treatment plans, and what a comprehensive PCS program actually looks like.
The ANS: why it matters for your recovery
If you’ve been dealing with PCS for a while, you’ve probably heard a lot about your symptoms — but very little about the system that’s driving them. That system is the Autonomic Nervous System (ANS).
The ANS is your body’s master control system. It regulates everything that happens automatically — your heart rate, blood pressure, breathing, digestion, immune response, sleep, and your body’s reaction to stress. You don’t think about any of these things. Your ANS handles them.
After a concussion, the ANS can get stuck in a state of high alert. Think of it like a car alarm that won’t turn off. The original threat — the injury — is gone, but the alarm keeps sounding. That constant activation keeps your nervous system in overdrive, which perpetuates every symptom you’re experiencing: the headaches, the dizziness, the fatigue, the anxiety, the sleep problems, the brain fog.
Most concussion treatment focuses on individual symptoms. Headache management here. Vestibular therapy there. But if the ANS is chronically activated, it will keep driving those symptoms regardless of how well individual components are treated. It’s like bailing water without plugging the hole.
BRN’s Concussion Bootcamp treats both the brain injury and the ANS — together, in one integrated program. That’s why our outcomes are different. And that’s why understanding the ANS is the first step in understanding your recovery — and your path to Go Forward.
Glossary of terms
Brain injury and rehabilitation come with a lot of jargon. Here’s a plain-language guide to the terms you’ll encounter most.
Mild Traumatic Brain Injury — the clinical term for concussion.
Traumatic Brain Injury — brain injury caused by an external force. Ranges from mild (concussion) to severe.
Acquired Brain Injury — any brain injury that occurs after birth, including TBI, stroke, anoxia, and infection.
