“I’m dizzy” tells you almost nothing.
Lightheaded, spinning, rocking, pulling, foggy — these are five different perceptual experiences, and they point to five different parts of the nervous system: autonomic, peripheral vestibular, central vestibular, cervical, and multisensory/limbic.
In persistent post-concussion syndrome, these systems rarely fail alone. A patient can have autonomic dysregulation, otolithic dysfunction, cervical proprioceptive mismatch, and visual dependence all at once — which is exactly why symptom-matched treatment (“do vestibular rehab because the patient is dizzy”) so often stalls or backfires.
Objective testing — VOG/VNG, positional testing, neuro-visual testing, tilt table, posturography, cervical exam, — is what lets you match treatment to mechanism instead of guessing from a single vague word.
