WHAT IS IT?
This is a study that is often used in the
evaluation of seizures, confusion, and other disorders of the brain, and records
the electrical waves of the brain. Using a paste, electrodes are applied to the
scalp, and your brainís electrical activity is recorded on a computer. It takes
an hour to an hour and a half while you sit comfortably on a recliner.
You will be asked to relax, and avoid
unnecessary movements. During certain parts of the test, the technologist may
ask you to watch a strobe and/or hyperventilate. These are routine parts of the
test that allow better evaluation of the results. There is no electrical
stimulation in this test. After the test, the electrodes will be removed, and
you may wash the paste out of your hair in our restroom.
HOW DO I PREPARE FOR IT?
Please clean and
dry your hair on the morning of the test. This makes it
easier for the technologist to apply the electrodes. You
may continue your medications unless requested
otherwise. In certain situations, you may be requested
to limit your sleep on the night before the test to
allow you to fall asleep during the test.
There may be some
discomfort while the electrodes are applied to the
scalp, but most people tolerate the test without
