What is an EEG?
This test helps us to find out more about the
kind of seizures or events you are having.
During the test, a camera records your
behavior. This is paired with an EEG
recording of your brain wave activity.
Sometimes, movements may look like
seizures, but they are not. If you have
seizures, this study will help us learn how
strong they are and how often they occur. It
will also help us find out what part of the
brain the seizures are coming from.
This test will also help us decide if you are
having silent seizures. These are seizures
that occur without any physical signs.
Changes can be seen on the EEG with this
type of seizure.
The test is painless. There will not be any
shots or special medicines used. Small
metal disks will be placed on your scalp.
Your hair will be moved out of the way.
These disks will be held in place using
special glue, made just for this test.
A gel (salt jelly) will be placed in each disk.
The gel allows us to pick up your
brainwaves. We will wrap your head and
the wires with a gauze bandage to keep them
secure for the day.
The time needed for an outpatient video
EEG may be from 2 to 8 hours.
ξ Try to arrive 15 minutes before
scheduled test time.
ξ Please bring with you any items to
keep you busy such as books, cross
word puzzles, movies, videos, and
other such things.
ξ Your hair must be clean for this test.
Wash it the night before or in the
morning and do not apply a lot of
conditioners, gels, or sprays.
ξ If the test is ordered as ‘Sleep
Deprived’, try to stay up as late as
you can the night before without
using any products that help you stay
awake. See the Health Facts for
Sleep Deprived EEG #4207.
ξ You will be in a large, comfortable
room for the day. There will be a
TV/VCR/DVD along with a Play
Station for games in the room.
ξ You will be asked to stay in this
room for as long as the test takes
except to use the restroom which is
just outside the room.
ξ You need to have a support person
with you during this test. This
person will be given breaks when
ξ You may purchase food items from
the cafeteria or you can bring your
own snacks from home.
ξ When the test is complete, the disks
will be removed with a mineral-oil
based remover. Your hair will be
somewhat oily when you leave. This
will shampoo out. You may choose
to have the disks removed with nail
polish remover to avoid the problem
of oily hair. This has a strong odor.
We will not use it unless you ask for
After the Procedure
Full test reports are almost always ready in 2
weeks. Results may be given over the
phone or at a later visit.

your insurance company. Not all insurance
