What This Helps Measure

Electrophysiology-based mapping sometimes used in specialist cognitive evaluation.

Which theories this can evaluate

  • Structural or Vestibular Load:Cervical strain, vestibular dysfunction, post-concussion effects, or positional head/neck load can distort clarity, orientation, and stamina.

What It Does Not Prove

One biomarker rarely settles the full question on its own. It is most useful when the pattern already suggests why it matters.

How To Prepare

  • Review contraindications and prep instructions from the imaging center.
  • Bring prior reports for comparison where available.
  • Ask for a written report and discuss findings in clinical context.

How To Use This Test Well

Step 1

Confirm indication

Use Quantitative EEG (qEEG) when your clinician agrees it will change management.

Step 2

Obtain complete report

Request both summary and technical findings for second-opinion compatibility.

Step 3

Map findings to next action

Translate findings into one concrete next step in your clinician plan.

What To Watch For

  • Technical quality and interpretation can vary by site.
  • Findings must be interpreted with symptom timeline and differential causes.
  • Normal report does not automatically rule out functional contributors.

Result Context

normal

Within lab range; compare with your target context (Interpretive report).

Result may be acceptable but still needs symptom correlation and trend review.

borderline

Near thresholds or inconsistent with symptoms.

Consider repeat testing, timing factors, and related markers before conclusions.

abnormal

Outside expected range or clearly discordant with baseline.

Use clinician-guided follow-up and structured differential workup.

What To Do Next

  • Save the result with date and symptoms from the same week.
  • Review alongside related tests instead of interpreting in isolation.
  • Use one concrete next step in your panel plan.
