qEEG Testing (Quantitative Electroencephalography)

Commonly referred to as Brain Mapping, qEEG is an advanced, non-invasive diagnostic protocol that records and analyzes electrical activity in the brain to detect specific patterns of neurological dysfunction often associated with concussions or mild traumatic brain injuries.

qEEG goes significantly deeper than standard traditional EEGs by utilizing sophisticated statistical computations to compare your raw brainwave data against comprehensive, age-matched normative databases. This metrics process generates detailed, color-coded topological brain maps highlighting explicit abnormalities—such as excessive theta/delta slowing, reduced alpha power, or disrupted structural connectivity—that frequently persist even when standard structural scans (like CTs or MRIs) return normal results.

qEEG is commonly used in post-concussion care to:

• Identify subtle electrophysiological variances lingering in post-concussion syndromes.
• Assess the physiological roots of persistent symptoms like brain fog, chronic headaches, sleep disruptions, and mood volatility.
• Guide personalized data-backed clinical protocols such as neurofeedback or neurological rehabilitation.
• Track objective milestones of brain function recovery chronologically over time.

The entire recording process takes between 30–90 minutes, utilizes a comfortable, lightweight electrode cap without any ionizing radiation, and is completely safe and painless for all age groups. While it is not intended as a standalone diagnostic tool for acute, immediate concussions, it provides key objective insights when integrated into a multimodal, comprehensive evaluation framework.

Note: Per major clinical guidelines, qEEG remains designated as investigational for routine, frontline concussion screening due to ongoing multi-center research expanding its exact diagnostic specificity and utility profiles.

Benefits of qEEG Testing

• Exposes functional electrical brain processing abnormalities invisible on standard anatomical imaging.
• Provides empirical context to better validate and explain persistent, lingering concussion symptoms.
• Supports highly customized target planning tailored to your exact neurological mapping.
• Tracks recovery velocities objectively, showing physiological improvements via follow-up scans.
• Empowers patient education by letting you visually understand the maps guiding your care path.

Today, qEEG brain mapping is actively used across specialized concussion treatment networks, complex neurology practices, neurofeedback spaces, and multidisciplinary functional rehabilitation centers for a deeper window into overall brain health.
