DidarNovin ClinicThe first time you hear the term "brain mapping" or QEEG, it is natural to wonder exactly what it measures and how it supports treatment. Brain mapping is a supplementary assessment tool, not a standalone diagnostic device.
What Is QEEG?
QEEG, or quantitative electroencephalography, records the brain's electrical activity through non-invasive electrodes on the scalp and then quantifies this data for comparison against reference patterns.
What Information Does It Provide?
This assessment can offer information about patterns related to attention, arousal, and regulation of brain activity — information that, alongside a clinical history and examination, contributes to a fuller picture of a person's condition.
How Is It Different From Standard EEG?
Traditional EEG is mostly used to examine seizure-related patterns; QEEG quantifies the data, enabling statistical comparison against a reference database.
Important Limitations
QEEG results are never a substitute for a psychiatrist's clinical diagnosis and must always be interpreted alongside a full clinical examination. To learn how to prepare before a session, read What to Do Before a QEEG Session; to better understand your report, see Interpreting Your QEEG Report. If you are exploring a related treatment path, see What Is rTMS? (coming soon).
Summary for Patients
Brain mapping is a non-invasive, painless assessment that provides supplementary information about brain function. Results must be interpreted by a psychiatrist alongside other clinical findings, not on their own.
