Cervical
Designed for a 60-second scan in primary care. Use this to explain why this theory fits, what would weaken it, and which tests are most worth discussing.
Why this still fits
My neck symptoms and brain fog seem to track together. I want to know whether cervical instability could be contributing, what imaging would show this - and whether any MRI I have had is sufficient for this question.
What would weaken it
- -No neck pain, head-position sensitivity, cervicogenic symptoms, or positional worsening around the fog.
- -Normal exam and imaging combined with a story that fits migraine, PCS, sleep apnea, or anxiety better.
- -The fog behaves independently of neck strain, posture, or head movement.
Key points to communicate
- •I want to know whether the neck is genuinely driving the cognition or just coexisting with it.
- •Please separate cervical causes from PCS, migraine, sleep apnea, and dysautonomia.
- •If cervical mechanics are plausible, I want to know which exam findings or imaging would actually matter.
Bring this to the visit
- •A description of positional symptoms: does fog worsen upright, with head movement, or looking down?
- •Any prior imaging: MRI, CT, X-ray of the cervical spine.
- •History of hypermobility, EDS diagnosis, or connective tissue disorder.
- •A note about whether a soft cervical collar trial improved symptoms.
Useful screening structure
- -Upright MRI with flexion/extension views - standard supine MRI misses dynamic instability.
- -Beighton score or Brighton criteria if hypermobility is suspected.
- -Cervical collar trial (2 weeks supervised) as a low-risk diagnostic test.
Tests and measurements to discuss
CCI Imaging
Questions to ask directly
- •Could cervical instability explain my positional cognitive symptoms?
- •Should we get an upright MRI with flexion/extension rather than a standard supine scan?
- •Would a supervised cervical collar trial help confirm or rule out this mechanism?
- •If instability is confirmed, what are the treatment options: PT, prolotherapy, or surgical?
Functional impact snapshot
- -Rate fog severity in different positions: lying flat, sitting, standing, head flexed.
- -Track whether screen time duration or head position at a desk correlates with fog onset.
- -Note whether any physical interventions (collar, posture correction) change symptoms.
Escalate instead of self-managing if
- •Progressive weakness, numbness, or loss of bladder/bowel control suggesting cord compression.
- •Severe headaches with visual changes or signs of increased intracranial pressure.
- •Rapid neurological deterioration after trauma or manipulation.
