If your child is old enough, they may also ask them to do some tasks during the test, such as close their eyes for short periods of time, take deep breaths by blowing on a windmill (over-breathing) or look at flashing lights (intermittent photic stimulation). At the same time, the digital video recording of your child will be made – this is helpful for the doctor to observe any symptoms, changes in behaviour or movements that could be associated with seizure activity on the recording.ĭuring the test, the CP may ask your child to lie or sit quietly if possible or continue to play. Your child will not feel anything while the EEG is being recorded. The CP will record your child’s brainwaves on to the computer and monitor them on a screen – they look like wiggly lines. The electrodes are attached by wires to a ‘headbox’ and then to the recording machine. The EEG had a tumultuous beginning no one believed it was real (read Decoding the Electric Brain for its curious history). When epilepsy is present, seizure activity will appear as rapid spiking waves on the EEG. The EEG measures aggregate electrical activity across millions of cells but there are many complexities to consider.
WHAT IS AN EEG FREE
While all the electrodes are being applied, your child can sit on a chair, the bed or your lap, and can play with toys – we have many toys in the department but feel free to bring your child’s own favourite book, toy or comforter. An EEG is used to evaluate several types of brain disorders. This should take around 20 to 30 minutes. Your brain cells produce tiny electrical charges when they are stimulated by the electrodes. Your scalp is pasted with thin wires and electrodes made of metal discs. This does not hurt but some children do not like it. An EEG is a test that measures the abnormal electrical activity of your brain or the abnormal waves of your brain. Sometimes, additional electrodes may be applied to other areas in order to get more information.Īs each electrode is attached, the CP will clean the area of the scalp with a cotton bud and some cream. Extra electrodes will also be applied on the shoulders to record your child’s heart rate and muscle activity. Sometimes, they will measure the head beforehand and mark the points with a soft pencil before attaching the electrodes. It records patterns of activity during rest and in response to certain.
The CP will attach a number of small silver discs (electrodes) to certain points on your child’s head using a soft paste. An EEG evaluates brain function by measuring the electrical activity within the brain. Or, your doctor may ask you to stay overnight in a special EEG monitoring unit where your brain activity will be monitored continuously.Staying safe at GOSH and outside the hospitalĬoming to GOSH for a day or inpatient admissionĬoming to GOSH for an outpatient appointment You will be able to go about your normal routine as the EEG is being recorded. During the test, small electrodes (small metal discs) are placed on. Learn more about this diagnostic test from a trusted source. An EEG, or electroencephalogram, is a recording of the electrical activity of the brain. It can be used to diagnose or monitor conditions such as epilepsy and sleep disorders. In addition to the electrodes, you will wear or carry a special recorder for up to 3 days. An electroencephalogram, or EEG, is a test that measures the electrical activity of the brain. If your doctor needs to monitor your brain activity for a longer period, an ambulatory EEG will be ordered.
WHAT IS AN EEG HOW TO
Find out how to prepare your child and what to expect. The test is done by an electroencephalogram technologist in your doctor's office or at a hospital or laboratory. Electroencephalogram (EEG) is a test that helps doctors evaluate electrical activity in the brain.
