Dec. 20, 2002 -- Biofeedback, a therapy
in which patients are taught to control physiologic functions such as
heart rate, muscle tension, and even their brain waves, is emerging as
an effective treatment for attention deficit hyperactivity disorder
(ADHD). And new research suggests that it may be especially beneficial
to patients who can't tolerate or don't benefit from often-used
stimulant medications.
Although prescribing drugs such as
Ritalin and Adderall are the most common way of managing ADHD -- and
bring improvement in about 80% of patients, says the American
Psychiatric Association - they are not without problems. Many children
taking them suffer side effects such as sleep problems, weight loss,
jitters, and stomach upset, and nearly half of those with some types of
ADHD don't respond to the drugs at all. Some experts are also concerned
with their long-term use.
But a new study, published in the
December issue of Applied Psychophysiology and Biofeedback,
indicates that ADHD kids who had weekly sessions of biofeedback therapy
for a year were able to reduce or eliminate their medication - and
maintained the same level of improvement in focus and concentration as
when they had been on drug therapy.
Vincent J. Monastra, PhD, of the FPI
Attention Disorders Clinic in Endicott, N.Y., studied 100 children
between 6-19 with ADHD for a year, all of whom were taking Ritalin and
had school and family counseling. But half of the children also had
weekly EEG biofeedback therapy, in which they were hooked to a device
that measures the activity of their brain waves. "At the conclusion
of treatment, all of those who underwent biofeedback were able to cut
their medications by at least half - and still enjoy the improvements
they got from the drugs. And about 40% were able to discontinue their
medication," he tells WebMD. "The kids who didn't get
biofeedback needed to continue medication to sustain improvements."
Why biofeedback, which has shown success
in treating a host of conditions including migraine and other headaches,
chronic pain, digestive problems, hypertension and substance abuse?
"Studies show that about 90% of ADHD kids have an under-arousal in
activity in the front lobe -- the region of the brain that is involved
in sustained attention, focus, concentration, and problem-solving,"
Monastra says. With biofeedback, the theory goes, ADHD patients can be
"taught" to bolster activity in these brain areas.
In these sessions, Monastra's study
participants were placed in front of a video screen whose characters
moved only when the children produced a short but sustained burst of
activity in those areas of the brain thought to be under-aroused. In
essence, the 51 patients who got biofeedback played a video game that
continued only when they exercised the portion of their brain that is
deficient in the ability to focus and stay attentive.
"It's like physical therapy for the
brain," explains Monastra, who has studied biofeedback's effect on
ADHD for several years. "Every time they produced a half-second
burst of activity over the frontal lobe, they were reinforced by the
screen to continue."
After a year of study, the children in
both groups showed improvement in attentiveness from medication and
other treatments. But what happened when the researcher abruptly stopped
their medication for a full week?
"If you didn't have the biofeedback
and I took way your medicine," says Monastra, "you were back
to square one -- your scores from a very thorough evaluation and medical
exam indicated that you had significant problems. But if you had
received biofeedback, scores on behavioral ratings of teachers and
parents, scores on attention and EEG tests measuring brain activity
remained in the normal range of what had been achieved with the drugs.
In other words, the kids who got biofeedback maintained the gain they
achieved with medication, even without the medication."
Monastra tells WebMD that he isn't
suggesting that biofeedback be used instead of medication, but it might
offer new hope to many patients. "There are those ADHD children who
don't respond to the medications, or they develop side effects that
really get in the way of their treatment, or they come from families
with a history of substance abuse. For them, this appears to be a great
alternative."
According to a recent study in Psychiatric
Times, biofeedback is used at some 1,500 clinics and treatment
centers for various psychiatric applications -- including ADHD. The
Association for Applied Psychophysiology and Biofeedback reports that
when used to treat ADHD, up to 80% of patients show "significant
improvement in the condition and a marked reduction in medication
requirements." A biofeedback session typically costs $60 to $150
and lasts about an hour, says Monastra.
"I have treated thousands of ADHD
patients with biofeedback since the 1960s and most of them have wound up
not needing their medication," says George Von Hilsheimer, PhD, who
runs a biofeedback treatment center in Florida that specializes in
treating ADHD patients. "You are training the brain to respond, a
little at a time. It's like teaching a child how to walk. They get a
little more success with each step."
