How Does
Neurofeedback Work?
Our daily lives are filled with times when we use feedback to help us
improve performance of a task. Consider, for example, how much easier it is
to control the speed of a car when you can look at the visual feedback
provided by the speedometer. You also get clues about your speed from the
sound of the engine (auditory feedback). Shaving in the morning is a lot
easier (and safer!) with the visual feedback provided by one's reflection in
the bathroom mirror. Neurofeedback works by giving you instant real-time
information about your brain waves. You can then use that information to
control brain wave activity.
What Is Neurofeedback
Used For?

There are many psychiatric and medical disorders that are associated with
abnormal patterns of brain wave activity. For example, many children and
teenagers who have Attention Deficit/Hyperactivity Disorder (ADHD) have an excess of theta wave activity
and not enough beta activity. In other words, their brains are working too
slowly to effectively perform externally focused activities. It is common to
see the brains of ADHD kids slow down when they open their eyes, which is
exactly the opposite of what should be happening. Neurofeedback treatment
for this type of ADHD would involve first learning how to reduce the excess
theta, followed by training to increase the amount of beta.
Some
ADHD children and adults have an excess amount of alpha activity. High
amplitude alpha that occurs when the eyes are open is associated with
inattention and distractibility. As with excess theta activity, having too
much alpha means that your brain is not running at its optimal speed.
Treatment would consist of learning how to reduce the amount of eyes-open
alpha to a normal level.
Other conditions that
have abnormal brain wave patterns and respond to treatment with
neurofeedback include anxiety disorders (typically excess beta), drug abuse
(not enough theta and/or alpha), learning disabilities (amplitude
asymmetry), and traumatic brain injury (excess theta, elevated coherence).
Neurofeedback is also used to treat intractable epileptic seizures by
increasing activity in the sensorimotor rhythm band (12-15 Hz), which has
been shown to reduce the occurrence of seizures.
A Typical
Neurofeedback Session
A neurofeedback training session begins with placement of one or more
sensors on your scalp and ears. The sensors are connected to the
neurofeedback equipment, which amplifies your brain waves and sends them to
a computer. You sit in front of a computer monitor and watch a display that
changes as your brain waves change. For example, you may be trying to make a
circle get smaller by reducing theta waves or make a jet plane go higher on
the screen by producing more beta waves. A typical neurofeedback session
lasts for 45 to 50 minutes.
How Do You Know
Which Part of the Brain Needs Training?
Before neurofeedback therapy is started, a test called a quantitative EEG
(QEEG) is performed. The QEEG is a test of brain wave activity that helps
create a neurofeedback treatment plan that is specifically designed to meet
your needs.
How Long Does
Neurofeedback Take?
Learning to control your brain waves takes a long time because we have very
little natural feeling for what our brain waves are doing. In contrast, we
have very good ability to know where our arms and legs are positioned. Try
closing your eyes and touching your nose with your finger. The length of
time needed to complete neurofeedback therapy depends on the needs of each
individual. A typical child or teen with the high theta/low beta form of
ADHD probably will require approximately 40 to 50 training sessions. It is
best to have at least two neurofeedback sessions per week. Having three or
four weekly sessions speeds up the learning process.
How Successful is
Neurofeedback?
As with all forms of medical and psychiatric treatment, a successful outcome
cannot be guaranteed. However, over thirty years of research and clinical
experience have demonstrated that neurofeedback can be an effective
treatment for ADHD and other conditions. One recent study with ADHD children
found that over 80% of those who were given neurofeedback therapy had
significant improvements in performance on a test of attention. Another
study showed that neurofeedback produced an average increase of 10 IQ test
points and a significant decrease in inattentiveness in ADHD subjects.
Multiple research studies have demonstrated that neurofeedback training can
reduce the frequency of seizures.
Neurofeedback and
Medications
Neurofeedback therapy can be done at the same time that you are taking
prescription medications. It is strongly advised that you continue taking
your medication(s) while doing neurofeedback. When your course of
neurofeedback therapy is finished it may be possible to reduce or eliminate
some medications, though there is no guarantee of being able to do so.
Does Neurofeedback
Have Side-Effects?
One of the advantages of neurofeedback is that side-effects are very rare.
You may find that learning to control your brain waves is a frustrating
process, especially at the beginning of treatment. Patients sometimes feel
tired at the end of a session. Patients with sensitive skin have had
reactions to the products that are used to clean the skin or hold the
sensors in place on the scalp or ears. There have also been rare instances
when neurofeedback training has gone too far and produced unwanted
side-effects. This can be easily corrected by some training in the other
direction, such as down-training excess beta that is producing
irritability.
Does Insurance Pay
For Neurofeedback?
Coverage for neurofeedback depends on your insurer and particular insurance
policy. At this time, we are a fee-for-service provider. We present billing
information that may be submitted to insurers for reimbursement as an out of
service provider. However, we make no guarantee that any of our services
will be reimbursed and payment by our clients is required at the time of
service.
