QEEG
(Quantitative Encephalograph) is a dynamic tool used to aid in the
diagnosis and treatment of several neurophysiological disorders,
especially ADD/ADHD. The QEEG, also known as brain mapping, is used to
measure the efficiency of electrical interaction between the various
regions of the brain and correlates the results to the patient’s area(s)
of difficulty. These findings provide a “road map” which guides us in
providing the most effective and cost efficient Neurofeedback therapy.
The QEEG is a crucial element in the diagnostic process due to various
subtypes of Attention Deficit Hyperactivity Disorder and its prevalence to
co-exist with other neurophysiological disorders. Observations,
questionnaires, and cognitive tests alone cannot determine what type of
ADD/ADHD a patient may have. Many individuals with ADD/ADHD are
misdiagnosed and given the wrong medication or treatment plan their
current brain state is unknown.
Brain mapping is a painless and non-invasive procedure. Sensors are gently
placed on the patient’s scalp and asked to engage in various tasks such as
reading and math computation. The patient’s brainwave activity is
monitored and recorded. The data collected is presented in a comprehensive
report that illustrates a patient’s brainwave activity, identifies problem
areas and under what task (i.e. reading or math), and determines how to
treat it.
The above illustration is an example of Frequency Ratios collected from
patient. It shows the ratios between Theta/Alpha, Theta/Beta, and
Alpha/Beta ratios. The bars at the bottom of the screen indicate brainwave
energy level, from decreasing (purple) to increasing (red) activity. The
QEEG determined this patient had excess theta in the mid-posterior section
of the brain.
QEEG Preparation There is not a lot of
preparation for your QEEG but here are some important considerations:
Have the day be as "normal" a day as
possible. For example, don't schedule dental work, start an
exercise program, give up or start smoking, or have a fight with your boss or
teacher on that day.
-
Get a good night's sleep the night before your
QEEG.
-
Don't go on or off medications that
day. If a physician has you tapering or starting medication, it
may be better to postpone your QEEG, please check with us if this is the
case.
-
If you take a Neurostimulant
for A.D.D. it is best to NOT take it on the day of the QEEG, but please check
with your physician. If you do take the Neurostimulant
that day, let us know.
-
Do not take any over-the-counter medications
on the day the QEEG is done. If you do, please let us know.
-
Washing your hair just prior to the QEEG will
make the hook-up procedure easier and faster. However, make certain
your hair is dry, not braided, and do not use conditioner, cream rinses, hair
gels or sprays on the day of the QEEG.
-
You should eat a healthy meal about two hours
or so before your QEEG. It is advisable to limit fluid intake two hours
before and avoid caffeine and foods or drinks heavy in refined sugar
(sucrose).
The QEEG normally takes 1 1/2 - 2 hours to complete and may take
longer with younger children especially if they are hyperactive or
oppositional.
