The QEEG (quantitative EEG, a map of brain electrical patterns referenced to normative databases) issue is major in neurofeedback circles. Most of us old-timers don’t really see a need for QEEG in determining protocols–it is definitely not necessary for the three most often used systems in at EEGym. But I’ve come around to see its tremendous value diagnostically; sometimes it can tell us what is wrong with the patient with dramatic clarity, whether it is old head injury, sleep disorder, ADHD, headache, or generalized memory problems.
