A Quantitative EEG (qEEG) is a painless, diagnostic test that records the electrical activity of your brain. It has no side-effects and is useful for determining brain related conditions such as attention disorders, anxiety, depression, stroke, tumor, head injury, memory difficulties and seizures.
During your appointment, the technologist will measure your head and use a sticky paste to apply 21 sensors, called electrodes, to your scalp, an electrode to each ear lobe, and one electrode to your chest for recording your heartbeat.
Throughout the test, the room will be in partial darkness and you will sit quietly in a comfortable chair. At times you will rest with your eyes closed, and at other times, your eyes will be open. We will also record while you use a laptop to interact with some computer-generated sounds and shapes.
Next, you will be asked to do some deep breathing for about three minutes, and lastly, you will rest in the recliner with your eyes closed for about twenty minutes. During that time, we would like you to be comfortable and relaxed, and if possible, take a brief nap. When the testing is complete, the technologist will remove the electrodes and try to remove most of the paste.
At home, any remaining paste can be removed by shampooing with warm water. It will take about ten days to analyze your data and write a report, so please schedule your follow-up appointment to discuss your results after that time. This information will aid in development of appropriate interventions that are tailored to your needs. If you have any other questions, please feel free to call the office or ask your technologist before the test.
