Condition

I can not really figure out. It is kind of hard for me to focus. Fog brain.

What we hear from brain fog patients on the first call.

What it is

Brain fog is a symptom of the nervous system not running clean. Upper cervical dysfunction, chronic sleep disruption, vagal tone problems, and stress all show up as brain fog.

What causes it

Foudy sees a recurring pattern: forward head posture, atlas/axis subluxation, and autonomic nervous system dysregulation. The surface EMG (what Foudy calls "an EKG of your nervous system") measures the function side, not just the pain side.

How we diagnose and treat it

Surface EMG to look at how the nervous system is firing, AP open-mouth X-ray for the upper cervical relationship, postural exam, and lifestyle conversation (sleep, hydration, screen time). Treatment combines upper cervical adjustments with the lifestyle work.

Symptoms we look for

  • Trouble focusing on tasks you used to find easy
  • Forgetting words mid-sentence
  • A "dim" or "foggy" feeling in the head
  • Often accompanied by neck tightness or headaches

Cost

First visit: $90 (consultation, exam, EMG, X-rays).

Timeline

Brain fog driven by upper cervical dysfunction often shifts inside 3–6 weeks of care plus lifestyle adjustments. Long-standing fog takes longer.

Common questions

Is brain fog really a spine thing?
Some of it is, some of it is not. The EMG and the upper cervical X-ray tell us whether the spine is in the picture. If it is, treatment helps. If it is not, we refer to the right specialist.
Should I see a neurologist first?
If you have new or progressive cognitive change, see a neurologist. If you have chronic foggy days and a stiff neck, start here. Foudy is direct about which is which.
What lifestyle changes matter most?
Sleep quality, screen hygiene (especially the angle your head sits at), hydration, and the corrective exercise program with Melanie. These compound.
What is the EMG actually showing?
Surface EMG measures the electrical activity of the muscles along the spine. Patterns of hyperactivity or asymmetry suggest the nervous system is running stressed. It is a functional measurement, not a pain measurement.

A show-and-tell consultation includes the exam, the EMG, and the X-rays. You leave knowing what is going on.
