Brain mapping · qEEG Durban
Quantitative EEG brain mapping near Durban.
Quantitative EEG (qEEG) transforms a standard brainwave recording into a detailed topographic map of brain activity — revealing patterns invisible to the naked eye. The EEG & Snoring Clinic is one of very few centres on the KwaZulu-Natal South Coast offering clinical qEEG brain mapping.
Quantitative EEG (qEEG), also called brain mapping, uses advanced mathematical analysis of the brain's electrical activity to produce frequency-band power maps across the entire scalp. Unlike a standard EEG — which a specialist reads visually — qEEG applies spectral analysis to compute precise measures of brainwave amplitude, coherence, and asymmetry at every electrode site.
The resulting topographic brain maps are compared against a large normative database of age-matched healthy individuals, highlighting regions where your brain's activity deviates from expected norms. These deviations are clinically meaningful and can correlate with cognitive, emotional, and neurological symptoms.
qEEG is also the essential first step for personalised neurofeedback therapy — the brain map identifies which sites and frequency bands require training, ensuring the neurofeedback protocol is tailored specifically to your neurophysiology.
Why choose qEEG?
- Objective, data-driven neurophysiological assessment
- Detects subtle patterns invisible on standard EEG
- Age- and sex-matched normative comparison
- Guides targeted neurofeedback protocol design
- Provides a baseline to track treatment progress
- Non-invasive and completely painless
Clinical applications
What qEEG brain mapping is used for.
qEEG provides objective neurophysiological data across a broad range of conditions where standard clinical assessment alone may be insufficient.
ADHD Assessment
qEEG can identify characteristic brainwave patterns associated with ADHD — including elevated theta/beta ratios — supporting diagnostic clarity and guiding treatment selection, particularly where stimulant medication is being considered.
Anxiety & Stress Disorders
Elevated high-frequency beta activity and asymmetric frontal alpha patterns are commonly seen in anxiety disorders. qEEG mapping provides an objective neurophysiological baseline for treatment planning.
Sleep Disorders
Quantitative analysis of sleep EEG architecture reveals abnormalities in slow-wave sleep, sleep spindles, and arousal patterns that standard EEG review may miss.
Post-Concussion & TBI
qEEG is sensitive to the diffuse slowing and frontal dysregulation that follows traumatic brain injury or persistent post-concussion syndrome, providing objective documentation of neurological impairment.
Cognitive Decline
Early changes in brainwave patterns precede clinical symptoms in many neurodegenerative conditions. qEEG can serve as a neurophysiological biomarker to supplement clinical and neuroimaging assessment.
Neurofeedback Protocol Design
A qEEG brain map is the essential first step before beginning neurofeedback therapy — it identifies which brain regions and frequency bands require training and forms the personalised treatment protocol.
The process
From recording to report.
EEG Recording
A 19-channel or higher-density EEG cap is placed on your scalp. You rest quietly with eyes open and eyes closed while several minutes of data are captured.
Artifact Removal
The raw EEG is carefully reviewed and cleaned to remove movement artifacts, eye blinks, and muscle noise, ensuring only genuine brain activity is analysed.
Quantitative Analysis
Specialised software performs spectral analysis, computing absolute and relative power across delta, theta, alpha, beta, and gamma frequency bands at every electrode site.
Normative Comparison & Report
Your results are compared against a validated normative database matched for age and sex. Deviations are colour-mapped and summarised in a detailed clinical report.
