Post-Concussion Treatment That Works

You're In The Right Place

Is this you?

If any of these sound familiar, you're in the right place.

You were "cleared" months ago but you're still not right
Headaches hit daily — dull, crushing, or both
Light and sound overwhelm you in ways they never used to
Brain fog makes it hard to work, study, or hold a conversation
Exercise makes your symptoms worse — you've learned to avoid it
You feel dizzy or off-balance in busy or bright environments
Doctors have told you to rest and wait — but the waiting isn't working
You've been dismissed because your MRI was normal
You want to know what's actually broken in your brain — and how to fix it

Most PCS workups end with "your scan is normal." Ours starts with what the scan can't see.

A normal MRI rules out bleeding and structural damage. It does not measure whether your brain is regulating blood flow correctly, whether your vestibular reflexes are misfiring, or whether neurovascular coupling has broken down after your injury. Those are functional failures — and they don't show up on standard imaging. That's where we begin.

Data Callout

Up to 30% of concussion patients develop persistent symptoms lasting months or years. Why? Because most concussion care is built around structural imaging that was never designed to detect functional neurological failure. A normal scan doesn't mean nothing is wrong. It means the wrong variables were measured.

It starts with your first week.

Your first day at the clinic is a full day of neurological testing. It measures the systems that regulate blood flow to your brain, not just heart rate and blood pressure. From there, you proceed directly into personalized treatment for the rest of your first week.

What You Can Expect From Diagnostic Testing With Us

What your diagnostic day includes

Our diagnostic workup brings cutting-edge methods from leading neurovascular and concussion research — including real-time cerebral blood flow measurement and functional neurological assessment that most concussion specialists still don't have in routine practice. We do — and we use them with every patient.

Transcranial Doppler (TCD)

We measure blood flow to the brain in real time. After a concussion, the brain often loses its ability to regulate that flow precisely — and the moment we can show you that on a screen, the "invisible" injury becomes visible for the first time.

Capnography (EtCO₂)

CO₂ directly controls how brain blood vessels dilate and constrict. After concussion, breathing patterns often shift in ways that compound cerebral hypoperfusion — a variable almost nobody measures, and one of the most treatable in the picture.

Exertional Threshold Testing

We identify the precise point at which physical or cognitive exertion begins to compromise cerebral blood flow — giving us an objective threshold to work within, and a measurable target to push above as you improve.

Visual & Oculomotor Assessment

We assess the visual and vestibular systems using video-oculography (VOG) and pupil response testing. If these systems are misfiring, they can keep your autonomic nervous system stuck in overdrive.

Autonomic Stress Testing

We use deep breathing, Valsalva, and postural stress to measure how your autonomic system responds and recovers under challenge. Then we layer in cognitive, cervical, and visual demands, because many patients only break down under combined load. What looks manageable at rest often becomes obvious when the system is pushed.

Bedside Neurological Examination

Some of the most important findings still come from an experienced doctor examining you directly. We assess reflexes, eye tracking, cervical motion, and coordination to catch the neurological patterns that may not show up on a screen.

Targeted Neuroplasticity

Your treatment plan doesn't exist until your data does.

Your rehabilitation is not a program that existed before you walked in the door. Nothing is prescribed before we know exactly where the failure is and what's driving it. Instead of rest, time, and generic PT being your only options, we prescribe an individualized neurological treatment — dose-specific to your needs, within your tolerance threshold.

We know PCS is not one thing.

Whether your primary bottleneck is vestibular, oculomotor, cervical, autonomic, or neurovascular — we strip away the labels and identify the mechanism that's failing in you specifically, so we can treat the actual problem rather than the presentation of it.

"Normal imaging" doesn't mean nothing happened.

A CT or MRI checks the structure of the brain. It does not check neurovascular coupling, cerebral autoregulation, or vestibulo-ocular reflex integrity. Those are the systems that govern function — and they can fail completely while your scan looks perfect.

We objectively measure progress.

Subjective improvement can be placebo or temporary. We don't just rely on how you feel to measure progress. We retest you objectively throughout your visit, comparing data points to verify real measurable improvement — so you leave with proof, not just hope.

After you leave.

Virtual follow-up is included with your visit. Your protocols go home with you, and we're here to support you along the way. If questions come up or you need guidance, you can reach out through your patient portal for feedback, protocol adjustments, and ongoing support, helping you stay consistent with what's working until you no longer need us.

A Different Approach To Concussion Care

Category	Conventional Care	The Keiser Clinic
Framing	Normal imaging = no structural injury. Rest and wait for recovery.	Imaging checks structure. We check function — neurovascular coupling, cerebral autoregulation, and reflex integrity. These fail while scans look normal.
The Symptoms	"It's likely anxiety or stress. Here's a referral."	Brain fog, dizziness, light sensitivity, and crashes are measurable neurological events — not psychological responses. We find the mechanism.
Testing	CT/MRI returns normal. No further workup ordered.	Real-time cerebral blood flow, CO₂ reactivity, vestibular and oculomotor reflex testing, exertional threshold assessment — measuring what actually fails.
Treatment	Rest, time, generic PT, and symptom management	Individualized neurological protocols — built from your functional data, targeting the specific system that is your bottleneck.
Progress	Patient self-report. "Give it more time."	Objective retesting throughout your stay — if the data doesn't change, the protocol does.
Exertion	"Avoid anything that makes symptoms worse" — no threshold identified	We measure your precise exertional threshold with real-time monitoring — then use it to build capacity without triggering a crash.
Doctor Access	15–45 minute specialist visits spaced months apart	Multiple treatment sessions per day with a full clinical team, with direct follow-up after you leave.

How It Works

Reserve your first week. Stay as long as you need.

We intentionally see a small number of patients each week. When you're here, you have a full clinical team — not a rotating roster of one-off appointments.

The first day is your full diagnostic evaluation. The rest of your stay is personalized treatment built around what we find, and we consistently retest to measure your progress objectively rather than going on how you feel. Most patients stay 2 to 4 weeks, and some stay longer. You go home with a program built from your own results, and that program is what keeps the progress going. That's true whether you stay 2 weeks or 6.

We don't run a copy-and-paste concussion rehabilitation program. We become your care team and design a protocol specific to you.

No Guesswork

Nothing is prescribed before we measure what's failing. Your protocol is built from your data — not a standard concussion template.

Full Evaluation

You'll have the most comprehensive neurovascular workup available for PCS, and we build your treatment directly on what it reveals.

Common Questions

Before you reach out, you probably have questions.

We do not treat with medications, supplements, or brain retraining programs. If you've tried all of those and they didn't work, we offer something different.What we do here is strip away your diagnosis label and assess how your nervous system performs, compensates, and breaks down in real time and under different loads of stress. Our clinic combines methods from various disciplines such as neurology, vestibular therapy, physical therapy, chiropractic, and more.The treatment methods often seem simple, and they have to be, in order for patients to continue them at home. Where we get specific is in the dosage, the consistency of coordinated care over time, and our ability to objectively measure progress by retesting.

That is one of the most common concerns we hear, especially from patients who have been mostly housebound or bedridden. Many of our patients were convinced they were too unwell to make the trip, right up until they arrived. Our team can help you think through the logistics, timing, and lodging options that make the visit as manageable as possible.If a visit isn't possible right now, we give away everything we know, publicly. You can start with our Roadmap and work through it with your care team at home. There are hundreds of educational videos on our YouTube channel, and a community of patients joins us live every Thursday to learn and ask questions. We publish the thinking behind our testing and our treatment so you and your doctors can decide what applies to you, even if we never meet.

You can verify whether your insurer may reimburse you for your care with us by asking them which of our diagnostic and treatment codes they cover. While we're not contracted with any insurance carrier, many patients have out-of-network benefits that make them eligible for reimbursement. You do not need a referral or insurance approval to be treated here, and HSA and FSA funds are accepted.

We don't offer doctor consultations by phone or video, because we can't form a doctor-patient relationship with you until we've evaluated you in person. You can learn more about why on our how this works page.

You're a unique case, so we couldn't be honest if we published a single success rate. Those numbers average together people with different mechanisms, severities, and years of illness. When a study reports improvement, it often reflects how many participants happened to fit a one-size-fits-all protocol. That tells you very little about your own case. If you fit neatly into a bucket, you wouldn't be here still looking for answers.This also asks something of you. Most patients arrive here having spent years working hard to get better, but lacking an aim for that effort. The patients with the best outcomes bring that work ethic, and we give it an aim. We work hard together while you're here, and you leave with what you need to continue making progress at home.

By the time you're seriously considering visiting us, you have likely already been through a lot, physically, emotionally, and financially. You will find no false hope here. If we don't believe we can help, we'll tell you. Our roadmap shows how we think and keeps nothing we do secret.The nervous system changes the way fitness does, through repeated work over time. You get the best care possible while you're with us, and you go home with a program. Your consistency with it takes you the rest of the way.Many doctors on our staff have either had these conditions themselves or cared for someone who did. You are not alone, and you won't be after you return home.
