Attention Deficit Hyperactivity
Disorder
When is a difference in attentional style, activity level and/or
interest
level a disorder?
When are these differences an advantage, simply an Attention Difference
Difficulty?
What alternatives are there to stimulant, anti-convulsant and
anti-depressant
medicines?
Background
Attention Deficit Hyperactivity Disorder (ADHD) is a condition
that
results in easy distractibility, impulsiveness, and for some persons,
greatly
increased activity levels. This increased activity may be a learned
compensation
for a very under aroused central nervous system. The activity levels
range
from being “fidgety” to being in constant motion, tapping feet and
fingers,
getting into things, and disrupting others’ studying, work and play.
Moderate
to severe levels of the disorder are accompanied by poor school and
social
performance. Children and adults with the disorder are likely to be
seen
as underachievers. Often there are academic problems surrounding poor
reading
comprehension, difficulty with completing tasks, and not turning in
work
on time or at all. Check our ADHD problem
checklist.
These children and adults may be forgetful, may appear or
become
uncooperative and typically develop negative self images as they
experience
failure and are given negative messages about themselves by schools,
parents
and peers. They often appear not to be listening or to lose interest
easily.
They are easily hurt or "oversensitive." They may appear to lack
judgment
in social situations, failing to take others needs and social
conventions
into account.
Sleepy Brain Waves
ADHD, which can occur with or without hyperactivity, is
considered a
disorder of relative “under arousal," following observations that these
children often show smaller and/or slower than normal physiological
reactions
to stimuli and signs that their brains are operating at lower levels of
excitement. That's why physicians started trying stimulant medication
with
ADHD. The most common finding in people with ADHD is more
"sleepy" (low frequency) patterns appearing in the brain electrical
activity.
This is seen in the image, below, which was recorded with a 19 channel
digital EEG while a teen with ADHD symptoms was listening:

This excess slow wave activity is often most pronounced during
reading
or listening tasks. During this high amplitude low frequency activity,
the person will "miss" what was being said. If these slow waves are
more predominant over the prefrontal regions of the brain that regulate
impulsivity, the person will probably be reactive to anything that
happens and "not think twice" about the consequences. That may be why
the amphetamine-type medications
create
the so-called paradoxical effect of calming down the behavior of ADHD
children.
What seems to be happening is that their brains are getting stimulated
enough by the drug to allow them to regulate impulses, focus and pay
attention.
The hyperactivity may also in part be a coping mechanism to
maintain
something like normal arousal. We have observed that when we first get
hyperactive children to sit still, they rapidly drop off into a drowsy
state. These folks seem to live at the edge of sleep, much like a
driver
who is getting tired and involuntarily dropping off, even though
fighting
it.
The brain activity can look much like Stage 2 sleep
("theta"activity) while the person is
trying to read. ADHD is often marked by increased "sleepy waves" in the
EEG.
You can, however, always see brief periods of activation in the raw
EEG.
These "operants" of focus and alertness spontaneous periods when the
brain
becomes more activated are the moments which neurotherapy identifies
and
reinforces.
Many young children with
"ADHD" show this excessive theta activity, particularly over the front
end of the brain. The frontal and prefrontal (behind your forehead)
regions do "executive" things: planning, motivation, impulse control.
The systems behind those in frontal cortex regulate attention, ignoring
distractions, persistence and precise motor (muscle) control as well as
"mirroring." There are specialized neurons in part of the frontal
cortex (mirror neurons) that allow us to copy what we see others do,
even down to letting us feel what others feel. That's empathy. So if
the whole region is really too underexcited ("sleepy") to do the jobs,
you're going to have some problems.
Other people have too much
"alpha" activity over frontal systems. The systems are awake, but they
are just "hanging out," again, not doing their jobs. These patterns are
common in teens and adults with ADHD. Neurofeedback in this situation
simply lets the person know when their brain is a little bit more "on
the job."
An important teaching to these children (and adults) is
that
their natural
condition is not bad, even though it can create tough situations.
If a person with ADHD is reasonably smart, well loved and
learns
how
to use his or her unique traits, great
things may happen.
Having the tendency to get easily bored may lead to
creativity. In
fact,
we often teach adults to make slower, synchronized brain activity to
enhance
relaxation and creativity.
We teach that it is helpful not to be "stuck" in one
state of
awareness.
The natural state of these children seems to be to go into a wide field
type of attention- hence the easy distractibility.
We take the point of view that our clients are learning a
new,
useful
skill of focused attention not eliminating some defect. However, we
recognize
that if a child is too overactive, or simply cannot keep the attention
focused for long enough to succeed in class or to do homework,
something
must be done to help.
The problems with drugs:
- Even advocates of drug solutions for ADHD admit
only 70-80% of
children are helped by the medicines.
- Medicines always have side effects. These
include appetite
suppression, sleep disturbance (the medicine isn't completely out of
the child by bed time). Another common side effect is irritability and
angry reactivity as the medicine wears off. Motor tics and twitches
have also been associated with stimulant use, although there is ongoing
argument regarding whether the stimulant started the problem or just
"released" or worsened the problem in people who were already prone to
tic disorders.
- There is clear evidence that some of the drugs
(Straterra,
Cylert) can
cause very serious side effects, including liver failure. These side
effects are not well predicted even when regular tests of liver
function are done. Cylert
Warning
- The clinically effective dose level will
disappear by evening, so
there is usually no help for homework. Further, teenagers with ADHD end
up being out and eventually driving, going to parties, etc. long after the
effectiveness of the medicine has worn off. So they are out in the
world with no treatment at all after 9 or 10 PM.
- There is clear evidence that the stimulants can
and are abused,
overused and sometimes sold or traded amongst teens.
- There is recent evidence of increased rates of
violence and
suicidality with a wide range of psychiatric drugs, including the
stimulants and the antidepressants.

Abuse and toxicity of methylphenidate.

The
therapeutic use of methylphenidate for the management of
attention-deficit hyperactivity disorder in children is increasing. As
therapeutic use increases, the risk increases of unintentional
overdoses, medication errors, and intentional overdoses caused by
abuse, misuse, or suicide gestures and attempts. Side effects during
therapy, which include nervousness, headache, insomnia, anorexia, and
tachycardia, increase linearly with dose. Clinical manifestations of
overdoses include agitation, hallucinations, psychosis, lethargy,
seizures, tachycardia, dysrhythmias, hypertension, and hyperthermia.
Methylphenidate tablets can be abused orally, or they can be crushed
and the powder injected or snorted. Despite its abuse potential, there
is disagreement regarding the extent to which methylphenidate is being
diverted from legitimate use to abuse in preteens and adolescents.
<>Despite these problems,
in
severe
cases of impulsivity, hyperactivity and inattention, when the child is
truly suffering and people are getting angry and blaming with the
child, I will still recommend medication. This, however, is recommended
only as "first aid" until self-control training with neurofeedback can
be instituted and the effects of training begin to take hold.
Neurofeedback
Neurofeedback
is
an advanced form of biofeedback which allows the development of self
control
over the person’s brain wave activity. The electrical signals from the
brain are picked up by metal disks placed on the scalp in a simple,
painless
procedure. A computer analyses the brain waves and lets the person know
when they are producing desirable patterns consistent with alertness.
The
computer is set up to make sounds and changing screen displays which
act
as “feedback” about the brain waves. This "BIO-feedback" makes learned
self
control
possible.
SAY AGAIN? What is "biofeedback"?
Biofeedback means we measure some important biological
activity -
like muscle tension, heart rate, or EEG activity - and “feed it back”
to you. The principle has been around since the 1950's and has been
widely used to help people reduce headaches, muscle tension, regulate
blood pressure, even treat migraines.
The biofeedback principle is how we learn almost everything.
For
example, you learn to throw a ball more or less accurately by throwing
it, then watching where it goes. With some practice, you can get it to
go where you want. Biofeedback is the same idea. Most headaches, for
example, are caused by too much tension in the forehead, jaw and/or
neck muscles. Easy to say, but “seeing is believing.” Muscle tension
biofeedback, for example, actually shows you the tiny, changing amounts
of activity in your muscles, right on a computer screen. Once you see
it, you can really start taking control of it. After a short time, you
can also recognize your own internal feedback - the sensations of
muscle tension - so you don’t continue to need the computer. We couple
biofeedback with home relaxation practices aimed at getting you the
skill to feel more relaxed and comfortable more of the time.
Biofeedback coupled with home practice of simple relaxation methods
quickly gives people relief from symptoms as well as a terrifically
rewarding sense of self-control - something you don't get from
suppressing symptoms of pain or fear with medications.
Biofeedback can be a powerful part of non-drug treatment for anxiety,
sleep problems, “stage fright”, test or performance anxiety. We also
use it as part of the treatment of chronic pain problems from accidents
or from chronic stress.
Neurofeedback applies the biofeedback principle to
regulating
brain activity, allowing learned control of the attention and
mental/emotional states in general.

A
related problem: DEVELOPMENTAL VISUAL DISORDERS
Developmental
or behavioral optometrists provide advanced assessment
and treatment of developmental
visual disorders. Too frequently, assessment of children’s and
adult’s
vision is limited to measurement and correction of acuity, or clarity
of
vision. Further, in typical school vision assessments, only distance
vision,
not close visual acuity is assessed. Acuity is only one of many
elements
of good vision. Normal acuity near and far, binocular coordination, eye
movement skills, peripheral awareness and eye/hand coordination are all
critical vision skills needed for success in school.
Unfortunately, some eye doctors have claimed that optometric vision
therapy can "cure" ADHD, or that ADHD is "nothing but" a visual
disorder. This is simply not so. ADHD is a genetic tendency of the
brain to get into states that are not compatible with good attention.
This usually involves the frontal part of the brain. Part of the
control system for the aiming of the eyes is also in frontal cortex and
that system is probably going to be just as "sleepy" as the rest of the
so-called "executive" systems in the frontal brain. So perhaps that's
why poor convergence and divergence is pretty common in kids and adults
with ADHD. The point, however, that is important is that improving the
coordination of the two eyes so that better depth perception and aiming
occurs commonly improves reading, sports performance and therefore
improves active interest in
the world. This will be helpful, but not curative, in kids and adults
with ADHD. Vision training is a behavior modification issue and
perception was one of the earliest areas of scientific study in
psychology. Dr. Nash has extensive graduate training in
perception and psychophysics and was trained and supervised in
binocular vision therapy for 3 years by a very experienced senior
behavioral optometrist, Clayton Johnson, O.D. (now sadly deceased). Dr.
Nash's credentials to do binocular vision assessment and training are
registered with the Minnesota Board of Psychology. Complex
cases and those needing treatment for eye diseases and corrective
lenses are referred to appropriate eye specialists, for example, Four
Seasons Eye Care in Plymouth, MN.
Clinical Effectiveness of
these
Non-Drug Therapies for ADHD
Neurotherapy is a relatively new approach to ADD/ADHD. The
earliest
reports of success with it were published in the mid to late 1970’s.
Few
well-controlled clinical research studies had been done until recently.
The few that were published, however, were impressive. One study by
Joel
Lubar, Ph.D. showed that training for decreased theta reduced or
eliminated
ADHD symptoms. Reversing the training (trainng for increased theta)
brought
the symptoms back! Training for decreased theta again reduced or
eliminated
the symptoms. Michael Tansey, Ph.D. has published small, but similarly
impressive studies for over 15 years.
Increasing numbers of reports on the effectiveness of
neurotherapy
been published recently and presented at national conferences. A
very comprehensive bibliography containing most of the studies of
neurotherapy on ADHD, brain injury, anxiety, epilepsy and and other
disorders can be seen at
Two organizations have substantial annual conferences to
provide
a professional
forum for discussion, presentation of papers and teaching. These are
the
International Society
for Neuronal Regulation and the EEG Section of
the Association
for Applied Psychophysiology and Biofeedback. The latter
organization
has
been in existence for 25 years, focusing on biofeedback research and
practice.
Dr. Nash is part of a certifying board, the National Registry of
Neurofeedback
Providers, which certifies health care providers in the practice of
neurotherapy.
Unlike many forms of therapy in clinical settings,
generalization
of neurofeedback training to real world environments is very deliberate
and very effective. Generalization to the real world is accomplished in
three ways:
- Performing actual school tasks with school
books during the
neurofeedback
session;
- Coaching the parents to notice and reward
increases in
alertness, improvements
in memory, improvements in follow through, improvements in impulse
control,
etc.;
- Coaching the child to notice changes in
alertness and
attentional state,
with the aim of enhancing voluntary increasing of alertness as the
child
becomes more skillful at this.
- Working with the family to help them turn
what is often a
big
upset
into a cooperative adventure in coaching, tolerance, ups and downs,
frustration,
communication and JOY.
One of the major satisfactions to me personally is seeing the
children
blossom into more self aware, outward-oriented, sociable people. One
mother
explained to me that she and her husband were thrilled by the fact that
their 17-year-old son could now carry on a conversation, and that he
was
interested in dating and in having a summer job for the first time.
Another
parent of a 13 year-old girl, with ADHD who has been completely
withdrawn
from 40 mg Ritalin a day for two years now, told us her daughter has
been
transformed. She is still very high energy, but instead of being an
annoyance
to teachers and an underachiever, she is now a star of her small
hometown.
She is getting A’s and B’s and is proud to have been elected by her
school
to go to NASA Space Camp the summer after her neurotherapy. An 18 year
old girl with ADD has
become outgoing, and is achieving well in college three years after her
treatment. When we asked ‘what had changed,’ an 11 year old boy told us
very simply: "I can pay attention all the way through class. Before I
couldn’t."
These are typical of the stories we hear from parents of our kids. They
bring us tremendous gratification.
Costs and Cost Effectiveness
We think several
arguments
can be made supporting the cost/benefits of neurofeedback treatment
for ADHD. First, these clients
incur significant ongoing expenses when they are treated with Ritalin.
Since the drug is usually only taken during school hours, and rapidly
wears
off, the child’s behavior at home evenings, weekends, and during
vacations
is unlikely to improve, so medication treatment at best provides only
partial
relief in a complex clinical picture. Many parents are uncomfortable
with teaching their children to rely on drugs to perform well. Finally,
medications always produce side effects.
Summary
Neurotherapy and vision training should not be seen as a
"cure"
for
ADHD, or as an immediate substitute for necessary medications, but
rather
as a component of treatment that may allow children to learn to
activate
and focus their attention, while calming themselves physically. If the
child is depressed, over anxious, or having serious conduct problems,
or
if parents lack solid behavioral parenting skills, there may be a need
for individual and/or family therapy, and possibly psychiatric
medications.
If there are deficits in academic or social skills, it is very
important
that these be addressed through traditional means, with behavioral
therapy
and specialized academic skills training. The improved attentive skill
acquired through neurotherapy should make this kind of learning more
rapid,
but we must remember that the child may have effectively missed
important
academic and social learning.
The course of treatment with neurotherapy is 3-5 months,
depending
on scheduling. We strongly encourage parents to work closely and
cooperatively
with schools and teachers. We also urge parents to involve themselves
in
support groups to get much needed encouragement and emotional support,
as well as continuing education surrounding the parenting of these
children.
If you have an ADHD child, or if you have ADHD yourself, you
might
enjoy a solid relaxation break. I utilize deep relaxation as part of
ADHD
treatment. In particular, it is useful for coming to terms with your
own
easy boredom, and with staying awake with your eyes closed while you
relax.
Holding your focus and alertness while deeply relaxed takes practice.
You
can help focus your mind while "Learning
to Relax."

I
have
been making my patients aware of a communication from Abbot
Laboratories
in December, 1996. Abbot issued a warning describing 10 cases of liver
failure in children in the U.S. taking Cylert for ADHD. The warning
stated
"Because of its association with life threatening hepatic failure,
CYLERT
should not ordinarily be considered as first line drug therapy for
ADHD.
.. Of 13 cases reported as of May, 1996, 11 resulted in death or liver
transplantation, usually within 4 weeks of the onset of signs and
