qEEG Testing (Quantitative Electroencephalography)

Also known as Brain Mapping, is an advanced, non-invasive tool that records and analyzes brain electrical activity to detect patterns of dysfunction often associated with concussion or mild traumatic brain injury.

qEEG goes beyond standard EEG by using statistical analysis to compare your brainwaves against normative databases, producing color-coded maps that highlight abnormalities such as excessive theta/delta slowing, reduced alpha power, or disrupted connectivity—changes that may persist even when imaging is normal.

qEEG is commonly used in concussion care to:

• Identify subtle electrophysiological changes in post-concussion syndrome
• Assess persistent symptoms (e.g., cognitive fog, headaches, mood issues)
• Guide personalized treatments like neurofeedback or rehabilitation
• Monitor brain function recovery over time

The procedure takes 30–90 minutes, uses a comfortable electrode cap (non-invasive, no radiation), and is safe for all ages. It is not a standalone diagnostic for acute concussion but an objective tool in comprehensive evaluation, combined with clinical judgment and other assessments.

Note: qEEG remains investigational for routine concussion diagnosis per major guidelines, due to ongoing research on specificity and utility.

Benefits of qEEG Testing

• Reveals functional brain abnormalities invisible on standard imaging
• Helps explain lingering post-concussion symptoms
• Supports targeted, personalized recovery plans
• Tracks electrophysiological progress objectively
• Improves patient education and engagement in care

qEEG is utilized in specialized concussion clinics, neurology, neurofeedback, and rehabilitation practices for deeper insights into brain health.
