Mental Health & the Autonomic Nervous System Connection
Not responding to antidepressants?
That may not be resistance — it may be misidentification.
1 IN 3 PATIENTS
diagnosed with depression don’t achieve adequate results with standard therapy.
A growing body of research suggests some patients may have underlying physiological drivers that standard approaches don’t address.
They’re often labeled “treatment-resistant”… leading to higher doses or additional medications.

If we’re only measuring symptoms…
we may be missing the system driving them.
Emerging research

Brain Medicine
points to a
different perspective.
“Treatment-resistant depression may reflect underlying autonomic dysfunction rather than medication failure.”
When symptoms persist, it may point to underlying physiological factors that aren’t being evaluated.
The next step isn’t always more medication... It’s asking better clinical questions.

Introducing a Systems-Based Approach
Physio PS provides tools designed to objectively assess autonomic nervous system function in clinical settings.
This allows providers to:
Identify physiological drivers behind behavioral symptoms
Differentiate psychiatric conditions from system dysregulation
Make more informed, patient-specific decisions

The Clinical Gap
Are we treating the symptom…
and missing the system behind it?
A significant subset of patients diagnosed with depression do not respond to standard therapies.
They are often labeled “treatment-resistant,” leading to medication escalation rather than deeper investigation.
Emerging evidence suggests something important:
In many of these patients, the issue may not originate in brain chemistry alone.
Instead, it may involve dysfunction in the autonomic nervous system—the system responsible for regulating the body’s most critical moment-to-moment functions, including heart rate, blood pressure, and cerebral blood flow.
The Missing System
The Autonomic Nervous System
The brain does not function in isolation.
It depends on stable physiological regulation to receive consistent oxygen and nutrient delivery.
When autonomic function is impaired:
Cerebral blood flow can become inconsistent
Oxygen and nutrient delivery may be disrupted
Neurological performance can decline
The result?
Symptoms that closely resemble depression:
Fatigue
Low mood
Cognitive slowing
Brain fog
In these cases, the presentation is psychiatric—
but the driver may be physiological.
If we’re only measuring symptoms…
we may be missing the system driving them.
The Clinical Implication
This raises a critical question for providers:
If the underlying issue is dysregulation… can symptom-based treatment alone resolve it?
Without assessing autonomic function, clinicians may be:
Treating downstream symptoms
Missing upstream dysfunction
Escalating treatment without identifying cause
Why Autonomic Testing Matters
Because without measurement, the system remains invisible.
Autonomic testing enables you to:
Evaluate real-time physiological regulation
Detect patterns of dysautonomia
Understand how the body is influencing brain function
This is not replacing behavioral health. It’s refining it.
The Opportunity for Precision
The Brain Medicine findings highlight that autonomic dysfunction is measurable, identifiable, and clinically relevant in a subset of patients with persistent depressive symptoms.
When treatment isn’t working, the next step matters.
Not every case is purely chemical.
Not every non-response is resistance.
Not every solution is more medication.
If we’re only measuring symptoms…
we may be missing the system driving them.

Frequently Asked Questions
What conditions do you treat at your pain management clinic?
We treat a wide range of chronic pain conditions, including back pain, arthritis, fibromyalgia, migraines, and nerve pain, using personalized treatment plans.
What pain management techniques do you offer?
We offer a variety of treatments, including medication management, physical therapy, nerve blocks, injections, and minimally invasive procedures to address your specific pain concerns.
How do I know if I need pain management services?
If you’ve been experiencing chronic pain that hasn’t responded to other treatments, a pain management specialist can help evaluate your condition and develop a customized plan to reduce your pain and improve your quality of life.
Do I need a referral to visit your pain management clinic?
Depending on your insurance plan, a referral may be required. However, we welcome both referred and non-referred patients and can help guide you through the process.

Physio PS has been a gamechanger in uncovering the hidden autonomic dysfunctions that often underlie chronic fatigue, persistent pain, anxiety symptoms, and delayed recovery after whiplash and concussion. It’s given us answers when nothing else could — and a clear path to true healing.

As a VA Electrophysiologist, I’ve used ANSAR’s Parasympathetic and Sympathetic Monitoring for years with outstanding results. It delivers diagnostic insights no other tool can provide. One case—a Navy SEAL suffering from severe dizziness and disability—was accurately diagnosed and effectively treated using ANSAR technology, after traditional tests failed. The patient regained his health, quality of life, and independence. This tool is a game-changer for patient care and healthcare efficiency.
Michael Stopyra
I cannot say enough good things about Physio PS! This technology has done so much for me. I used to have terrible anxiety storms that would cause me to have high fevers. With this simple test, my doctor was able to find the root cause of my symptoms and prescribe a very low-dose medicine for about nine months to correct the primary problem. I have not had a high fever in four years!
