What Can a qEEG Brain Map Tell You?
A brain map can look impressive.
Colors appear across a head model.
Charts compare frequencies.
Patterns emerge.
But the value of quantitative electroencephalography—qEEG—depends on understanding what it actually measures.
EEG records electrical activity from electrodes placed on the scalp.
qEEG applies mathematical analysis to those recorded signals and can examine characteristics such as frequency activity and relationships among recorded sites.
At ARC, clinical qEEG uses a 19-channel recording when clinically appropriate.
What qEEG should not be presented as is a stand-alone diagnostic test for complex neurodevelopmental or psychiatric conditions.
A clinical review of qEEG concluded that its role is generally better understood as providing additional information alongside other diagnostic evaluations rather than independently pinpointing a diagnosis.
That distinction is central to ARC’s approach.
A brain map is data.
Clinical interpretation requires context.
Symptoms, developmental history, neuropsychological findings, medical information, behavioral observations, and the referral question all matter.
When neurofeedback is being considered, qEEG information may also contribute to individualized clinical decision-making.
But technology should support clinical judgment—not replace it.
A qEEG is one piece of information. Your Brain Blueprint™ is the integrated picture.
