The Dickinson Neurodiagnostics department and its staff of nationally
registered EEG Technicians, provides a variety of diagnostic tests, called
electroencephalograms (EEG), designed to determine the ability of the brain to communicate with the rest of your body.
What is an EEG?
EEG is short for Electroencephalogram. An EEG is a test commonly
preformed when you are suspected to be experiencing epilepsy or seizures.
What does an EEG do?
An EEG records brainwave activity from tiny electrical signals generated by your brain. The EEG machine then amplifies the signals recorded from your brain to a permanent record on a computer. A variety of diagnoses can be made through the interpretation of these brain wave records.
What happens during the EEG?
An EEG will last for about one to two hours. The EEG is painless with a
minimal amount of discomfort. You will be asked to sit or lie down for the
test. Electrodes will be put in place by the technologist. The
recording will generally last from 20 minutes to just over an hour unless
otherwise specified by your physician. During the test, the technologist
will flash a strobe light in your eyes, ask questions to test memory and may
have you hyperventilate for a few minutes. In most instances, you may be
able to sleep for part of the test.
