Quantitative Electroencephalography, or QEEG, is a diagnostic tool in which EEG data (electrical activity of the brain) is analyzed via computer software to create colored “brain maps.” These maps help clinicians see patterns of activity that may be associated with specific conditions (e.g., ADHD, anxiety, traumatic brain injury).
Key Points:
- Process: Electrodes placed on the scalp measure brain waves (e.g., delta, theta, alpha, beta). The data is then statistically analyzed and compared to normative databases.
- Clinical Use: Can guide neurofeedback protocols, help confirm diagnoses, and monitor treatment progress.
- Controversies & Considerations: While useful, QEEG should be interpreted cautiously and in conjunction with clinical interviews and other assessments.
- Applications: ADHD, anxiety, depression, learning disabilities, and certain seizure disorders, among others.
