ADD/ADHD
Who's Paying Attention?
Attention Deficit Disorder or Intention Deficit Syndrome?
The Biology of ADD/ADHD
"He just needs discipline!"
Most children and adults can focus and pay attention to a particular
task or subject when called on to do so. While playing or socializing
with friends, there is sharing and peaceful interchange; when interacting
with family members, there is rational behavior; when taking an exam,
most can concentrate on the questions, recall the studied information,
and write the correct answer.
For about one in ten, however, the ability to focus is blunted to a point of negatively affecting life. School or work is catastrophic, with failure the rule; family life is chaotic, with upheaval common; peer group and sibling relationships are "war."
Such a major, life-disrupting
problem with focus and attention may be what the medical, psychological
and educational community call Attention Deficit Disorder (ADD). If
the person also has a serious problem with impulsive behavior, with
excessive, socially inappropriate physical movement, the diagnosis
is likely to be Attention Deficit Disorder with Hyperactivity (ADHD).
It is Dr. Marvin
Sams', Director of Neurofeedback Centers of America, opinion that
the severe focus and attention problem commonly called Attention Deficit
Disorder is misnamed. Based on his experience of working with hundreds
of children and adults with a diagnosis of ADD/ADHD, he is convinced
that a more accurate designator is Intention Deficit Syndrome.
Attention, defined as the act of mentally concentrating on a single
object, thought, or event, is not the real problem in Attention Deficit
Disorder. Virtually all with a "pure" diagnosis of ADD (that is, without
co-existing learning disabilities) are able to focus, often in a very
intense way, on a task or project that is of high interest to him
or her. It is not uncommon, for example, for children who do poorly
in the classroom to play video games for hours on end, without eating
or even going to the bathroom.
Adults, particularly
men, may be unable to keep a job due to poor ability to focus and
perform required tasks. Yet, the same people are able to spend hours
in front of the TV, watching and being emotionally engaged in one
sporting events after the other. Attention is only interrupted during
commercials - - to get a snack, or to yell for someone else to get
it for them.
The inability to do undesirable
tasks or jobs is in and of itself not a malicious act; most children
and adults diagnosed as ADD are unusually bright, uniquely insightful,
and fun loving people. It's just that brain wave patterning prohibits
intentional and deliberate focusing on a task that is low or no interest.
Intention, that is, purposely focusing and
concentrating our mental powers on a single task or subject, whether
it is of particular interest or not, is not easy (and sometimes is
apparently impossible) for the person seriously affected with ADD.
The problem is not one of attention. Rather, it is a problem with
intention -- an inability to focus on purpose.
The
PET scan (positron emission tomography) is a special imaging technique
used to reveal where in the brain a task is being performed. In this
procedure, a glucose-based substance with a radioactive marker is
injected into the blood stream. As the brain uses its various specialized
areas to process and execute the assigned task, active cells "take
up" the glucose/radioactive substance. A special scan (picture) is
then taken.
Brain areas working on the task,
show as colors on the image, making for a dramatic display of where
the brain is doing its work.
In those with a clinical diagnosis of
ADHD, the brain does not take up as much glucose in certain brain
areas as people who attend normally. The ADHD brain is thus blocked
from processing incoming sensory information in the same way as a
normal brain does. (See Zemetkin, et al (1990) New England Journal
of Medicine 323:1361 for details.)
Additional
evidence for the biological basis of ADD/ADHD is in the brain wave
patterning. A recent study found 80% of children with ADHD had a specific
EEG signature of an excessive slow waves/deficient fast waves ratio,
while 75% of non-ADD (normally attending) children did not. (See Mann,
C. A., et al, (1992), Pediatric Neurology, 8:30.)
The Mann and associate's study shows the EEG patterning of most ADD/ADHD
children to be similar to the drowsing pattern of normal children.
The implication is the brain is under aroused ("sleepy", and not
able to sufficiently focus itself in the classroom and work place.
There are exceptions to the Drowsy Brain
Syndrome: In some, Alpha waves are excessively abundant and unyielding.
Since the brain uses Alpha activity to idle non-working parts of itself,
the person is unable to successfully participate in the world when
Alpha activity does not downshift to let faster frequencies take over.
The evidence is conclusive: there is overwhelming
evidence of a biological brain dysfunction in those with significant
and serious attentional impairment.
Excessive
slow/deficient fast waves, and unyielding Alpha brain waves, may cause:
* Reduced applied
intelligence
* Poor recall of studied material
* Diminished, or exaggerated, emotions
* Poor impulse control
* A distorted sense of time
As
demonstrated by recording brain waves during common classroom tasks,
strong discipline is not the answer to correcting unfocused, unruly
or inappropriate behavior in those with ADHD. The more pressure to
perform and comply, the more abnormal the EEG becomes. Forcing or
pushing a child or adult to "do better" causes performance to become
worse...sometimes much worse. It's a physical brain problem, not an
attitude problem.
Especially sad is the ADD/ADHD
child who wants to please his or her teacher or parent by doing a
"great job." Often as not, the harder the child tries, the worse the
outcome. Instead of the sought after praise, the only "reward" is
increased criticism from parents and teachers. The disappointment
often turns to frustration, then anger or depression as self esteem
spirals down. In the end, there is commonly extreme rage and acting
out.
Disciplining an ADHD child requires
patience and creativity. But considering the biological origin of
the behavior, it is the only choice that is fair to the afflicted
child.
In most ADD/ADHD children and adults,
Neurofeedback teaches the brain to perform at peer group levels, sometimes
better. The enhanced attentional performance and flexibility builds
self esteem, creating stable relationships among parents, teachers,
fellow students and workers, and bosses.
