Sleep Deprived EEG

Your doctor has ordered a sleep-deprived
EEG for you. A sleep-deprived EEG test is
done when you have had less sleep than
usual. An EEG is a recording of the
electrical activity of the brain. The EEG is
not painful, and you should feel no ill effects
from it. The test will take about an hour and
a half and you will be able to leave right
away after the test.

When you are tired, there is more chance
that there will be unusual electrical activity
in your brain. The sleep deprived EEG helps
your doctor diagnose a neurological
problem.

Your doctor may ask you to have this test if
you have had a standard EEG test but it
didn’t show any unusual electrical activity.

If you have any questions about the test,
please be sure to ask your doctor or nurse.

What to Do
 Stay awake from midnight until the time
of your EEG.
 Your hair MUST be clean for this test.
Wash it the night before or the morning
of your test. Do not apply conditioners,
gels, or sprays. You may eat and drink as
usual, but do not drink any caffeine after
midnight before the test (coffee, tea,
cola, etc.).
 If you are on medication, please, take
your medication as usual.
 Have someone drive you to the hospital
and home again as you will be very
sleepy after the test.


Arriving for the EEG
 There are volunteers at the main desk
who can direct you.
 Your EEG appointment is in the EEG
lab, J module/ 2nd floor
 Please register 15 minutes before your
scheduled appointment. Registration is
on the main floor as you make your way
on ‘Main Street’ to the EEG lab in the J
module. Follow ‘Main Street’ towards
the J module and Registration will be on
your right hand side. After registration,
continue right on ‘Main Street’ through
the H elevator lobby to the J lobby.
Please check in at the EEG desk.

The Procedure
A technologist will place very small metal
discs on your scalp using special glue. The
discs will be placed on your scalp. A gel
(salt jelly) will be put in each disc. This gel
allows us to pick up your brainwaves. Once
the test begins, it is important that you relax.
Though you will be sleeping during a
portion of the procedure, you may also be
shown a flashing light or asked to breathe
deeply for a short time. The test will take
about one and a half hours. At the end of
the test, the metal discs and glue will be
removed. The staff will explain how to
remove any glue residue that may remain in
your hair.

Results
The final report of your EEG will be sent to
your referring or primary care doctor within
a few days. He or she will discuss the
results of the test with you and recommend
treatment, if needed.
