What can an EEG detect?
What can an EEG detect?
An EEG can determine changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEG might also be helpful for diagnosing or treating the following disorders: Brain tumor. Brain damage from head injury.
How is an EEG test done on an infant?
Your child will be asked to lie on a bed or sit in a chair. The EEG technician will attach electrodes to different locations on the scalp using adhesive paste. Each electrode is connected to an amplifier and EEG recording machine. The electrical signals from the brain are converted into wavy lines on a computer screen.
How do I keep my baby awake before an EEG?
On the night before your appointment, keep your child up one hour past normal bedtime, and wake your child (and avoid naps) three to four hours before your appointment time. Bring a bottle, pacifier and/or other items that might help your child relax. Consider feeding your child while you’re in the lab.
What is an electroencephalogram ( EEG ) for children?
Electroencephalogram (EEG) for Children. What is an electroencephalogram (EEG) for children? An electroencephalogram (EEG) is a test that measures the electrical activity in the brain (brain waves).
How is an EEG used to diagnose brain problems?
An electroencephalogram (EEG) is a test used to find problems related to electrical activity of the brain. An EEG tracks and records brain wave patterns. Small metal discs with thin wires (electrodes) are placed on the scalp, and then send signals to a computer to record the results.
Is it safe for a child to have an EEG?
Most medical procedures have some risks. Talk with your child’s healthcare provider about the risks and benefits of this test for your child. The EEG has been used for many years and is considered a safe procedure. The test causes no discomfort. The electrodes record activity.
What kind of electrodes are used for EEG?
During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
What happens during an EEG?
During an EEG, the electrical signals of the brain are recorded. This electrical activity is detected by electrodes, or sensors, placed on the patient’s scalp and transmitted to a polygraph that records the activity.
What does EEG check for?
An EEG, also called an electroencephalography or electroencephalogram, is a test that detects the brain ’s electrical activity or brain waves. Doctors often use the test to evaluate head injuries or to diagnose neurological disorders. Depending on the reason for the EEG, the patient may be awake or asleep during the test.
What does an EEG reveal?
An electroencephalogram (EEG) is a neurological test which records the electrical activity at the surface of the brain by way of electrodes placed on or in the scalp. Because the EEG reveals changes in the electrical activity of the neurons in the brain, it can aid in the diagnosis of various pathologies.
