Our Neurologists at Central Vermont Medical Center perform Electroencephalograms (EEG) in order to study the electrical current within the brain.
An Electroencephalogram (EEG) is a technique for studying the electrical current within the brain. Electrodes are attached to the scalp. Wires attach these electrodes to a machine which records the electrical impulses. The results are displayed on a computer screen. The electrical impulses are then viewed and interpreted by a Neurologist.
The test is performed by attaching electrodes to the scalp with a paste. You may be asked to lie down and relax. During part of the test you will be exposed to a flashing light (photic stimulation) and/or asked to breath deeply and rapidly (hyperventilation). Some patients are asked to stay up all night before the test. Your referring physician will determine these special instructions. Under normal conditions, the test will take about an hour to conduct.
Preparing for the EEG:
- Wash your hair thoroughly (your scalp must be clean and dry), but do not apply oils, sprays or conditioners
- Eat a normal meal
- Take all prescribed medications and bring a list of all your medications with you
