For example, you may be asked to breathe deeply and rapidly for 3 minutes, or you may be exposed to a bright flashing light.This study is generally done by an EEG technician and may take approximately 45 minutes to 2 hours.If you are being evaluated for a sleep disorder, the EEG may be done while you are asleep.If you need to be monitored for a longer period of time, you may also be admitted to the hospital for prolonged EEG (24-hour EEG) monitoring.In cases where prolonged inpatient monitoring is not possible, your doctor may consider doing an ambulatory EEG.The reason you are having the test or procedure,What results to expect and what they mean,The risks and benefits of the test or procedure,What the possible side effects or complications are,When and where you are to have the test or procedure,Who will do the test or procedure and what that person’s qualifications are,What would happen if you did not have the test or procedure,Any alternative tests or procedures to think about,Who to call after the test or procedure if you have questions or problems,How much will you have to pay for the test or procedure. Some EEG tests require that you sleep through the procedure, and some do not. Do not stop using medicines without first consulting your healthcare provider.Avoid consuming any food or drinks containing caffeine for 8 to 12 hours before the test.Follow any directions your healthcare provider gives you about reducing your sleep the night before the test.

These sensors, called electrodes, pick up electrical activity from cells inside yourÂ.Once the recording begins, you’ll be asked to remain still.You can have an EEG at night while you're asleep.

Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp.Based on the results, what are my next steps?Are there factors that might have affected the results of this test in some way?Moeller J, et al. Medical root words come from many different languages (e.g., Greek, Latin, Arabic, French, and German) and find their way into English.
Electroencephalograph definition is - an apparatus for detecting and recording brain waves. This is due to the flashing lights or the deep breathing that may be involved during the test. Electroencephalogram (EEG)-A record of the tiny electrical impulses produced by the brain's activity picked up by electrodes placed on the scalp. Your healthcare provider may monitor you through a window in an adjoining room to observe any movements that can cause an inaccurate reading, such as swallowing or blinking.

Log in for more information. Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain.It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used, as in electrocorticography, sometimes called intracranial EEG.. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. Do not use any hair care products, such as hairspray or gels.Tell your healthcare provider of all medicines (prescription and over-the-counter) and herbal supplements that you are taking.Discontinue using medicines that may interfere with the test if your healthcare provider has directed you to do so. The EEG will look like a series of wavy lines. The test is done by pasting metal disks, called electrodes, to the scalp. These studies measure electrical activity in your brain in response to stimulation of sight, sound, or touch.The EEG is used to evaluate several types of brain disorders. The root of a word is the foundation of a medical term and provides the general meaning of the word.
