qEEG: a map of how your brain actually works.

Quantitative EEG measures the electrical activity of your brain and maps it across regions and frequency bands. The patterns it surfaces explain attention, sleep, mood, and cognition — and form the foundation for evidence-based brain health protocols.

The Technology

Quantitative EEG, explained.

qEEG is a non-invasive measurement of your brain's electrical activity. A soft cap fitted with sensors records the natural signals your neurons produce — no needles, no radiation, no contrast agents. Software then analyzes those signals and maps activity across different brain regions and frequency bands.

Unlike a standard EEG (used mainly to detect seizures or major abnormalities), qEEG quantifies subtle patterns: slow waves where there should be fast ones, asymmetries between regions, connections that should be strong but aren't. These patterns correlate with how your brain feels day-to-day — focused or scattered, calm or anxious, restful or wired.

What it Surfaces

The patterns qEEG can reveal.

qEEG is valuable across a wide range of brain health concerns. It is especially useful when the underlying picture is unclear — when symptoms like sleep, focus, mood, or energy don't have an obvious cause.

  • Attention issues — slow-wave activity in frontal regions where alertness should dominate
  • Sleep dysregulation — disrupted patterns during transitions to sleep states
  • Anxiety / overactivation — excessive fast-wave activity, particularly in the right hemisphere
  • Depression / underactivation — frontal asymmetry between left and right brain regions
  • Post-concussion / TBI — characteristic patterns that linger long after symptoms appear to resolve
  • Cognitive decline — early markers in network connectivity visible before noticeable symptoms

Candidates

Who qEEG is for.

qEEG is appropriate for patients who want a deeper picture of brain function — typically because something hasn't been responding to standard care. Trial-and-error medication, dietary changes, or general wellness interventions that haven't produced expected results often signal that the underlying pattern needs to be measured, not assumed.

It is also valuable for high-performers who want to optimize cognitive function rather than treat dysfunction — athletes, executives, and others for whom small gains in focus, sleep quality, and stress regulation translate into outsized real-world outcomes.

The Process

What to expect, start to finish.

From initial consultation to your results review — here is exactly how a qEEG evaluation unfolds at ASA Health MD.

  1. 01

    Initial consultation

    60–90 minute conversation with Dr. Lee covering history, current symptoms, and goals. We decide together whether qEEG is the right next step.

  2. 02

    qEEG recording

    45–60 minute session in our office. A soft sensor cap is fitted; we record at rest, eyes-open and eyes-closed, and during simple cognitive tasks.

  3. 03

    Analysis

    Your raw data is processed and benchmarked against age-matched normative databases — the comparison surfaces what is typical for your age vs. what is unique to you.

  4. 04

    Results review

    1–2 hour walkthrough of findings with Dr. Lee. You see your own brain map, understand the patterns, and review what they mean for your symptoms.

  5. 05

    Treatment plan

    Specific recommendations built from your qEEG findings — neurofeedback, targeted protocols, lifestyle changes, or medications when indicated.

Why ASA Health MD

qEEG, interpreted by a physician.

  • Normative comparison

    Your qEEG is compared against age-matched normative databases — so we measure what is unique to your brain, not just what looks active.

  • Integrated reading

    qEEG alone is a partial picture. We read it alongside neurological exam, history, and other imaging — never in isolation.

  • Physician-interpreted

    Dr. Lee reads your qEEG personally. Not delegated to a technician, not sent to a remote interpretation service.

  • Treatment-oriented

    The qEEG informs specific protocols, not just a diagnosis. You leave the results review with a concrete plan, not a label.
