Some EEGs do not include lights or other stimuli.
There are no risks associated with an EEG. They’re always working, even if you’re asleep.
Your brain cells communicate with each other using electrical impulses. What exactly is an EEG, and what will it do?Īn EEG, or electroencephalogram, is a test that records the electrical signals of the brain by using small metal discs (called electrodes) that are attached to your scalp. What is the difference between EEG and brain wave?.How long does it take to get result from EEG?.What exactly is an EEG, and what will it do?.

Seizure: uncontrollable convulsion, spasm, or series of jerking movements of the face, trunk, arms, or legs. Can be used for diagnostic testing to receive and record electrical activity of nerves. If you have further questions about this diagnostic test, contact the doctor that ordered the test or visit:Įlectrode: a conductor that carries current. He or she will communicate directly with your referring doctor, who in turn will discuss the results with you. How do I get the test results?Ī neurologist, or a doctor who specializes in brain and nervous system problems, interprets your EEG.
The technician will remove the electrodes and you should wash the glue out of your hair. Most of the time you will just lie still with your eyes closed. The technician may ask you to do several things during the test, such as asking you to open and close your eyes, breath deeply and rapidly (hyperventilation), or look at a flashing light. About 20 small electrodes will be attached to your head with washable glue. You will be asked to lie on a table or sit in a reclining chair.
Continue taking your medicine unless your doctor tells you to stop. You may eat regular meals, but avoid drinks that contain caffeine for at least 4 hours before the test. If you have long hair, do not braid, tie, or pin it up. #How does eeg work free
Make sure your hair is clean, freshly washed, and free from any styling products. Who performs the test?Ī technician can perform the test in the doctors office, a specially designed clinic, or in the hospital. It can also be used to confirm brain death. Other conditions such as dizziness, headache, dementia, and sleeping problems may show abnormal brain patterns. If it doesn’t detect the right patterns, you may still have epilepsy and ambulatory monitoring or video EEG may be necessary.ĮEG can also detect abnormal brain waves after a head injury, stroke, or brain tumor. An EEG is of value for diagnosing epilepsy only if it detects patterns typical of epilepsy. For example, if you have a seizure disorder, the EEG can show where abnormal activity in your brain comes from and can help distinguish between generalized or focal seizures. It is most often used to determine the type and origin of seizures. This allows you to be observed during a seizure so that your physical behavior can be monitored at the same time as your EEG.Īn EEG measures electricity that your brain makes it does NOT measure thoughts or feelings, and it does not send any electricity into your brain. You stay in the hospital and are monitored both by EEG and a video camera. Video EEG monitoring is available in specialized centers for patients with frequent seizures or sleep disorders. The EEG recorder along with a diary you keep of daily activities and drug dosages helps the doctor relate your activity to specific EEG recordings. #How does eeg work portable
Ambulatory EEG involves wearing a portable EEG recorder on a belt around your waist for several days or weeks. You will be given specific instructions regarding food, drink, and medications that may need to be avoided. Abnormal brain waves may appear when the body is stressed or fatigued. You may be asked to do a sleep-deprived EEG, which requires you to have only 4 hours of sleep. 
Standard EEG recording is done in the office and usually lasts an hour.There are several different ways to conduct an EEG: A sample EEG recording showing a focal spike typical of a seizure.
