What Is QEEG Brain Mapping? Why Is It Important in Autism?
How does QEEG work, what brain patterns are seen in autistic children, and what role does this mapping play in personalising and tracking treatment?
What Is EEG?
The brain is a complex electrical system in which billions of neurons communicate continuously. The electrical signals generated by this activity can be measured using an EEG (electroencephalography) device. EEG has been used safely in paediatric neurology for decades and is entirely non-invasive and radiation-free.
What Is QEEG and How Does It Differ from Standard EEG?
QEEG (Quantitative EEG, also called brain mapping) is the computerised analysis of the raw data produced by a standard EEG. While standard EEG allows clinicians to visually inspect brain wave patterns, QEEG converts these patterns into numerical values across dimensions such as frequency, amplitude, symmetry and inter-regional coherence.
The resulting data is compared against normative databases from same-age neurotypical individuals, allowing clinicians to identify objectively which brain regions are operating differently and in what way. The output is a visual map of the brain showing areas of over- or under-activity.
What Brain Patterns Are Typically Seen in Autism?
QEEG research in ASD populations has consistently identified several recurring patterns, though no two children have identical profiles:
These patterns vary in severity and combination from child to child — which is precisely why QEEG is valuable: it reveals the individual's specific neurological profile rather than applying a generic assumption.
How Is QEEG Performed?
The procedure is completely painless. The child sits comfortably in a chair and wears an elastic cap containing small electrodes that rest on the scalp surface — nothing is inserted or attached with discomfort. During the recording, the child can watch a video or play quietly. The session typically takes 30–45 minutes. The recorded data is then analysed and reported by a specialist.
What Does QEEG Contribute to Treatment?
QEEG's most important contribution is shifting treatment from assumption-based to data-driven. It serves several roles:
Before treatment: Establishes the child's individual neurological baseline, enabling personalisation of the stem cell protocol. Different brain patterns may call for different preparation strategies or follow-up priorities.
After treatment: Repeated QEEG at 3, 6 and 12 months provides objective, measurable documentation of neuroplastic change. This complements — and validates — parent and therapist observations.
Protocol adjustment: Findings from follow-up QEEG inform decisions about whether additional sessions are warranted and what supportive interventions to prioritise.
Without QEEG, tracking neurological progress relies entirely on subjective observation. With QEEG, those observations are anchored to measurable brain data.
QEEG in the Context of the Full Evaluation
At Vellorian Health, QEEG is one component of a broader pre-treatment evaluation that also includes biomarker panels (inflammatory cytokines, immune subset profiling), metabolic assessment and family history review. The combination of objective neurological mapping and biological profiling allows us to build a treatment approach that reflects the actual child in front of us — not a statistical average.
