Quantitative EEG (qEEG) is a diagnostic technique that measures and quantifies electrical brain activity using electroencephalography (EEG). It involves recording brain’s electrical patterns through a series of electrodes placed on the scalp, which are then analyzed and compared to a normative database to identify abnormalities and deviations from the expected patterns.

qEEG provides objective and measurable data about brain functioning, facilitating the evaluation of various neurological and psychiatric conditions. By analyzing the brainwave frequencies, amplitudes, and interconnections, qEEG can aid in the identification and characterization of cognitive disorders, mental health conditions, and neurological dysfunctions.

qEEG is commonly used in research, clinical practice, and neurofeedback applications, providing insights into neurological conditions such as epilepsy, ADHD, schizophrenia, traumatic brain injuries, and sleep disorders. It helps clinicians and neuroscientists gather quantitative data to better understand brain functioning and guide personalized treatment plans.
