Yall - this page is lighting up the facts. My goodness I wish I saw this page 5 years ago when I was in the throes of it all.
Thankful for my team of badasses that intuitively started working on the dura, fascia system, and calming my nervous system. Everything is connected and when there is a kink in the system, it messes with everything down the line.
This is why sacro-cranial work, FST, and trauma informed massage are my first recommendations when someone tells me they have suffered whiplash or a head/neck injury. We have got to get the fascia and dura moving fluidly as it encapsulates the muscles, houses the nerves, and plays a pivotal role in movement.
How I can help?!
Gentle yoga, flowing movements, meditation, and sound therapy help to bring the nervous system into parasympathetic so your body can start healing itself.
Stress and ANS dysregulation are HUGE contributors to inflammation, chronic pain, negative feelings, and stopping us from healing naturally.

THE HIDDEN LINK BETWEEN YOUR NECK, CSF FLOW, HEADACHES, DIZZINESS & BRAIN FOG — AND HOW WE ADDRESS IT AT theFNC
Most people think of brain health as purely neurological — chemistry, neurons, neurotransmitters.
But modern research is revealing something much bigger:
👉 Your neck mechanics and head movement patterns directly influence cerebrospinal fluid (CSF) flow.
👉 Your deep suboccipital muscles connect to your spinal dura through a structure called the Myodural Bridge (MDB).
👉 And impaired CSF flow may contribute to headaches, dizziness, pressure sensations, brain fog, post-concussion symptoms, and chronic autonomic problems.
This is one of the most important, overlooked areas in all of neurology — and it’s something we assess and treat every single day at The Functional Neurology Center.

🔍 WHAT THE NEW RESEARCH SHOWS
A 2021 paper published in Nature Scientific Reports (s41598-021-93767-8) demonstrated something powerful:
Simple head-nodding movements change CSF flow patterns in real time.
Researchers used advanced cine MRI to measure CSF movement at the cranio-cervical junction. After just one minute of gentle head nodding, they found:
• Significant changes in maximum and average CSF flow velocities
• Measurable shifts in direction of CSF flow
• Increased CSF pressure (confirmed through lumbar puncture in a separate group)
• Altered cranial ↔ caudal flow balance
This means that CSF flow is not only driven by heart rate and breathing…
Movement matters.
Neck mechanics matter.
Head posture matters.
And this is where the Myodural Bridge becomes clinically important.
⸻
🔗 THE MYODURAL BRIDGE: THE NECK–BRAIN CONNECTION NO ONE TALKS ABOUT
Deep under your skull, the small suboccipital muscles attach directly to the spinal dura — the protective sheath around your brainstem and spinal cord.
This connective-tissue linkage is called the Myodural Bridge.
Its role?
To transmit mechanical forces from your neck muscles to your dura — influencing CSF flow, pressure, and stability.
When these muscles function normally, the MDB helps:
• Maintain healthy CSF circulation
• Support brainstem mechanics
• Stabilize the cranio-cervical junction
• Assist with movement-driven CSF “pumping”
But when there is dysfunction — such as:
• Whiplash
• Concussion
• Forward-head posture
• Chronic neck tension
• Cervical instability
• Postural collapse
• Muscle hypertonicity
• Poor proprioception
• Trauma at C0–C1–C2
— the MDB may pull unevenly on the dura or fail to assist CSF movement properly.
And symptoms often follow.
⸻
⚠️ WHEN THE NECK–CSF SYSTEM FAILS, YOU MAY FEEL…
These are EXACTLY the patients who show up at theFNC every week:
• Head pressure or “internal swelling”
• Worsening headaches with movement
• Dizziness or lightheadedness
• Visual motion sensitivity
• Neck tightness with “pulling” into the head
• Post-concussion symptoms that never resolve
• Difficulty tolerating upright posture
• Brain fog and cognitive slowing
• Sleep difficulty or “wired but tired” states
• Autonomic symptoms (heart racing, temperature issues, anxiety-like sensations)
• Feeling “full,” “pressurized,” or “floating”
Many of these patients have “normal” MRI results — because standard imaging does not assess functional CSF dynamics, dural tension, MDB mechanics, or vestibulo-cervical integration.
But when we test them functionally, we find the root causes.
⸻
🏥 HOW theFNC EVALUATES THIS SYSTEM
We use a comprehensive Functional Neurology approach to evaluate:
✔ CSF-related mechanics through
• Positional testing
• Eye–head–neck integration
• Dural tension indicators
• Motion-driven symptom mapping
✔ Deep neck flexor + suboccipital muscle function
(Where the MDB originates)
✔ C0–C1–C2 biomechanics
(neutral, flexion, extension, rotation)
✔ Cervical proprioception
(accurate or distorted?)
✔ Vestibular mapping
(VOR stress tests, gaze holding, cervical-ocular reflex)
✔ Posture and gait under load
(brainstem + CSF dynamics often show through)
We look at the whole system, not just the painful area.
⸻
🌀 HOW WE TREAT IT AT theFNC
Treatment combines:
1️⃣ Correcting cranio-cervical mechanics
Gentle, precise mobilization + stabilization
2️⃣ Releasing and retraining suboccipital muscles
Normalizing MDB tension.
3️⃣ Movement-based CSF optimization
Inspired by the Nature study — controlled head-nodding, cervical patterning, rhythmic motion sequencing.
(This is also where Ciatrix-style movement and posture-driven fluid work fits beautifully.)
4️⃣ Vestibular and oculomotor integration
To restore brainstem and proprioceptive control over posture and head mechanics.
5️⃣ Dynamic balance and sensory-motor rehabilitation
Allowing the system to re-synchronize under real-world conditions.
6️⃣ Autonomic regulation
Breathwork, visual–vestibular drills, physiological sequencing to restore CNS balance.
7️⃣ Technology assisted therapies
Depending on the case:
• Laser therapy
• Neuro-modulation
• Motion platforms
• Proprioceptive training
• Cervical neuromuscular retraining
• VR vestibular integration

This is how we restore flow, not just treat symptoms.

🎯 WHY PATIENTS GET BETTER HERE
Because we look at something most clinics ignore:
👉 Your neck is part of your brain system.
👉 Your dura responds to movement.
👉 Your CSF responds to posture.
👉 Your symptoms often come from dysfunction in this system — not from the brain “mystically misfiring.”
When you restore healthy head–neck mechanics, normalize the MDB, and retrain CSF-related dynamics…
Patients often report:
• Clearer thinking
• Reduced headaches
• Better balance
• Less dizziness
• Improved sleep
• More stable energy
• Less anxiety-like autonomic symptoms
• A sense of being “grounded” and “in control” again
For many, this is life-changing.

🙌 IF YOU STRUGGLE WITH HEAD PRESSURE, DIZZINESS, NECK PAIN, OR POST-CONCUSSION SYMPTOMS — YOU DO NOT HAVE TO LIVE THIS WAY.
At theFNC, we specialize in complex neurological cases where the mechanical + fluid + sensory systems need to be rebuilt.
There is always a reason.
There is always a mechanism.
And there is always HOPE.
