Dysautonomia & Autonomic Dysfunction
We measure and train the systems that regulate blood flow to the brain — the variable most dysautonomia care never looks at.
If any of these sound familiar, you're in the right place.

Cardiovascular symptoms. GI dysfunction. Brain fog. Crushing fatigue. Temperature dysregulation. Neuropathy. For most patients, these arrive together — and so does the specialist list. A cardiologist for the heart. A gastroenterologist for the gut. Each treating their piece, none of them looking at what's driving all of it. The autonomic nervous system governs every one of those systems. When it dysregulates, they all dysregulate. Treating them individually while the underlying failure goes unmeasured doesn't resolve dysautonomia — it just manages symptoms indefinitely.
Cerebral blood flow can drop significantly on standing even when heart rate and blood pressure appear normal. Standard autonomic testing was never designed to detect this. That's not a gap in your symptoms — it's a gap in what most clinics are measuring.
Before booking your visit, schedule a free phone consultation with a Keiser Clinic physician. They'll listen to your story, answer your questions, and tell you plainly whether coming in makes sense for your situation.

Most patients who reach us arrive carrying more than one diagnosis. The autonomic nervous system governs cardiovascular function, digestion, immune regulation, temperature control, and peripheral nerve signaling — so when it fails, it rarely fails in just one place. Our workup is designed to find what's upstream of all of it, using methods that most autonomic centers still don't have in routine practice. Why dysautonomia is so often misdiagnosed and mistreated — and what changes when you test differently.

We measure cerebral blood flow in real time while you stand. Heart rate and blood pressure at the arm can look completely normal while blood flow to the brain drops significantly — TCD is the only way to see it.

CO₂ strongly influences brain blood vessel tone and blood flow — often revealing a breathing contributor that standard testing misses entirely.

We apply oculomotor, cervical, and cognitive challenges while measuring cerebral blood flow on a tilt table — to find the precise breaking points your resting test never captured.

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.

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.

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.
A Note From Our Team
Several of our doctors have been patients or caregivers themselves. They know what it feels like to be dismissed and sent home with no answers. When you become a patient here, you have a care team of doctors who understand where you've been — and what it actually takes to get better.
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. A diagnosis — or the absence of one — does not change how we approach you. The mechanism does. And the mechanism is measurable.
Whether your presentation is orthostatic hypotension, OCHOS, or something that never got a name — the upstream question is the same: where specifically is the autonomic system failing to regulate cerebral blood flow, and what reflex is the bottleneck? We test for that. Then we treat that.
MCAS. Small fiber neuropathy. Migraines. These are real diagnoses — and we're not dismissing them. But the autonomic nervous system regulates immune activation, gut motility, and peripheral nerve signaling. When cerebral perfusion fails and the autonomic system is in a chronic state of dysregulation, those systems dysregulate with it. Treating each one in isolation has a ceiling if the upstream driver is never addressed.
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.
Virtual follow-up is included in your visit. Your protocols go home with you. We check in, answer questions, and make sure you stay consistent with what's working — until you no longer need us.
Most patients who come to us carry more than one of these diagnoses. These pages exist because that is often how people find us, not because we treat each diagnosis on a separate track. Our testing measures what your brain and nervous system are actually doing. The label you arrive with does not change that.
"Standard treatment has a ceiling. We work above it — in the brain."
Some of what you may be prescribed during your visit

Retrains the balance system when dizziness, motion sensitivity, visual instability, or autonomic symptoms are being worsened by vestibular dysfunction.

Targets the visual control systems that stabilize gaze and helps the brain build a more accurate map of the body in space. This can reduce neurostrain, disorientation, overload, and instability under cognitive and sensory load.

Uses targeted stimulation, including tools like the Neuro20 suit, to improve sensory input from the body and give the nervous system better information to regulate from.

Addresses mechanical strain and poor sensory signaling coming from the neck and upper cervical region, where instability can interfere with brainstem function, and autonomic regulation.

Rebuilds cleaner movement patterns so activity becomes more tolerable and less likely to trigger compensation, overload, or crash responses.

Challenges the brain's ability to regulate under mental load, helping improve function when symptoms flare with thinking, multitasking, or divided attention.

Uses carefully dosed activity to improve tolerance and function without relying on generic exercise protocols like CHOP or GET that ignore cerebral blood flow, autonomic limitations, and issues related to fatigue.

Uses red light and laser therapy to support tissue recovery, reduce irritation, and complement neurological rehabilitation in areas that need targeted stimulation.

We use the non-invasive Magnetolith in patients with ligament laxity, including hEDS, to treat tendons and joints that may be contributing to instability in joints or the upper cervical spine.
| Category | Conventional Care | The Keiser Clinic |
|---|---|---|
| Framing | Autonomic dysfunction is evaluated by whether a diagnostic label is confirmed. If it isn't, the workup ends. | The label describes the presentation. The mechanism explains the failure. We test for the mechanism — regardless of what the label is or isn't. |
| Testing | HR and BP at the arm. Blood tests for vitamin deficiencies. Referrals to other specialists. | Real-time cerebral blood flow via TCD, CO₂ reactivity, vestibular and oculomotor reflex testing — measuring what standard testing was never designed to catch. |
| Treatment | Lifestyle adjustment, sodium, compression, and off-label medications — if a diagnosis was given at all | Individualized neurological protocols built from your functional data — targeting the specific reflex and neurovascular failure driving your symptoms. |
| Primary Metric | Systemic vitals as proxy for autonomic health | Cerebral blood flow velocity + EtCO₂ — measuring what the brain is actually receiving, not just what the arm reports. |
| Associated Conditions | MCAS, small fiber neuropathy, GI dysfunction treated separately by separate specialists — with no shared framework | Evaluated as part of the same clinical picture. When the autonomic nervous system is the common thread, we look there first. |
| Doctor Access | 15–45 minute specialist visits spaced months apart — if a referral was given at all | Multiple hours a day with a full clinical team during your stay, with direct follow-up after you leave. |
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.
Most patients stay two to three weeks. Some stay longer. But when you arrive, the only thing you commit to upfront is that first day of diagnostic testing. What comes after is your decision.
We don't run a copy-and-paste dysautonomia program. We become your care team and design a protocol specific to you — whether or not you came in with a diagnosis.
