ADHD Part 2

Hmmm… I said I would get back to you (my own ADD / ADHD is currently under control and I actually recalled that I would finish my discussion on ADD / ADHD interventions)… so here it is…

…while not a “magical” treatment or even a “new” healing program (this will not make Oprah or the Early Morning Shows), research also clearly indicates hat behavioral interventions are of significant benefit among children with features of disinhibiiton including ADD / ADHD symptoms. In addition to the previously identified environmental and parental interventions, research suggests that introduction of cognitvive behavior therapy (CBT) interventions have promise particularly among children over the age of about ten years. Great thing about CBT … you don’t need to drop $120,000 on an education to learn or use it!


CBT is a step-wise intervention strategy that includes:

(a) increasing self-observer functions by labeling emotions (ie., “it looks like you are feeling…”) (to assist in articulation of negative emotions)

(b) providing cues/assistance in identification of antecedents or triggers for negative emotions (ie., “when did you begin to feel that way? where were you?, etc.) (to assist in identification of trigger zones or antecedents)

(c) learning to identify that behaviors are choices (ie., “what did you choose to do with those negative emotions?”) (to enhance higher level executive contributions to behavior)

(d) assistance in identification of outcomes (ie., “how did that work out for you?”) (to facilitate self-observation and utilization of feedback)

(e) assistance in recognition of the extent to which outcomes influenced triggers (“did those outcomes change the triggers?”) (to avoid vicious cycles in which behaviors have no impact on the triggers).

Existing research indicates that cognitive-behavioral therapy (CBT) – type interventions are among “what works” among high risk children and adolescents involved in juvenile probation. Parental instruction in the use of these techniques is critical to success because the therapists are the parents. So, finally, you get to do something! In addition to formal programming or therapeutic strategies, avoidance of emotional trigger words including “should”, “why”, “have to” and “try” often proves beneficial. These four words (or phrases) are often viewed as parental words that tend to elicit child responses including oppositionality, aggression, withdrawal, etc. See the old stand-by book
I’m OK, You’re OK (Thomas Harris) for an explanation (read chapters 1-7). In lieu of these four curse words, insert choices (ie., what might you choose to do?) and questions (ie., what happened? when did it happen? what could you do?, etc.).

So… tired of waiting for the doctors to make things better? Want to get some control over your life and participate in the development and maturation of your child? Please do not “try” these interventions… but you could choose to implement them.

ADHD Part 1

“My four-year old son was just diagnosed with ADHD. My husband says it’s a lot of “hooey” (which I assume is Pennsylvania Dutch for BS) and that the physician is a drug pusher. His mother (good old mother-in-law) thinks all the drug companies are a bunch of crooks, no better than an organized form of crime. My best friend says it's an epidemic, no one ever heard of ADHD when we were kids. And me? I think… well… I don’t know what to think. What’s the truth?”

The statistics for ADD / ADHD are staggering; 3-10% of all children have symptoms consistent with a diagnosis of ADD / ADHD; 3.5 million children take daily ADHD medications; $3.1 billion was spent on ADHD medications in 2005, an amount that reportedly is four times the number in 2000. So, is it an epidemic? The statistics would say “yes” if an epidemic is defined in terms of a disease or disorder “that appears as new cases in a given human population, during a given period, at a rate that substantially exceeds what is expected, based on recent experience (the number of new cases in the population during a specified period of time is called the "incidence rate").” (taken from Wikipedia). However, is the epidemic real or related to other factors?

Research appears to indicate that improvements in our diagnostic tools (and accuracy), introduction of higher demands within the educational system (“No child left behind”) along with “punishments” for schools that “leave a child behind” and the advent of medications that are both safe and effective (ie., why diagnose a disorder if you cannot treat it) contribute to the dramatic increase in diagnoses of ADD / ADHD.

But beyond that, there is some equally compelling evidence that the actual incidence of children with ADD / ADHD is on the increase much like the diagnosis of childhood autism, cancers, etc. And the cause? Hmmm. round up the usual suspects, toxic chemical factors, stress associated with our high speed technology lives, poisoning (heavy metals, mercury, lead, etc.) and nutritional deficits. Add in two parents working full-time with children being rushed from home to day-care to stores to … (you get the point), over-stressed families who have moved away from grandparents and extended family support… 133 television stations, video games…

Since we are not in a position to treat our modern lives nor control our children’s exposure to atmospheric toxic substances or heavy metal poisoning beyond normal precautions, parents often feel both helpless and powerless. However, recent work has suggested that a combination of interventions that ARE under your control may just have an impact upon a subset of children presenting with symptoms of ADD / ADHD.

Biological interventions: One such “biologcial” program under the control of parents (I’m excluding medications at this time since parents do not control medications) is the 4-A Healing Program of Dr. Kenneth Bock. The 4-A (which stands for ADD / ADHD, Autism, Allergies and Asthma) Healing Program components include: (a) Nutritional Therapy, (b) Supplementation Therapy, (c) Detoxification Therapy and (d) Medication. While the program may not work for all children with ADD / ADHD symptoms, existing evidnce along with anecdotal reports indicate that a subset of children do show benefits and from a cost-benefit analysis the cost of being wrong (ie., good nutrition, good diet, etc.) is minimal relative to the potential benefits. Will it work for your child? I do not know nor is there any evidence that anyone can identify children who will be responders.

Environmental interventions: Unfortunately there are no magic program or McDonald’s drive-through solutions. But we do know that providing high levels of structure within the home is beneficial … structure the child’s room, desk, backpack, etc… structure the child’s time with schedules… daily schedules (ie., posted on the refrigerator) including homework and play times. Reduce the pace of life… children exposed to frantic paces elevate their own activity levels to match the pace required… and the number one internvetion? SPEND MORE 1:1 TIME WITH YOUR CHILD! This does not mean dropping the child off at soccer practice, but more like 1:1 coloring, drawing, walking, hiking, throwing a baseball, reading, fishing, playing board games. Your time is the best intervention and to the extent that you slow down the pace, your child will match your pace (remember the “mirror neurons”)!

Other avenues? Hmmmm… let me get back to you on that one.

The ADHD Bell Curve

“My seven year-old son is inattentive, off-task, distractible and has a short attention span. At home, he hops from one activity to another, never picks up anything … sort of an energizer bunny. The school suggested that we have him tested for ADHD. Does he have ADHD?”

“I was told (I love this one because the person who told them is never identified) that if your child was a climber as a toddler, then they have ADHD, that you can tell true ADHD in a child if he cannot fall asleep at night … if he stays up late.”

My first thought?, to be redundant, the doctors and nurses at the hospital should have told you about these things when you brought the baby home from the hospital. Children are inattention, they do not stay on task, they hop from one activity to another. Toddlers climb and infants are not always great sleepers.

The issue is not whether a child demonstrates or does not demonstrate a specific behavior or problem, but whether the frequency, duration and/or intensity of identified behaviors or problems are within the middle of the bell curve (the norm).

An understanding of the bell curve is critical to the concept of diagnosis. Ever heard of the bell curve? Well, this is what we know; all human performances (what people do) follow the normal bell curve. An example, a few people are fast, a few people are slow, but most people fall within the middle. A few people are strong, a few people are weak, but most people fall within the middle. The bell curve can be graphed as performance (horizontal axis) by the number of people (vertical axis) and when we graph these two factors, the graph looks like a bell with the highest number of people falling in the middle (called the mean) and progressively fewer people as one moves towards the extremes or tails.

The task is not to identify whether your child is inattentive (because we know that he is) but how much does his inattention (performance) differ or deviate from the mean or average child of the same age.

It turns out that not all children who are average fall exactly on the mean so we need to establish a “tape measure” to determine how much a child deviates from the mean. This measure of deviation from the mean (or “gold standard”) is called the standard deviation. About 2/3 children fall within about one standard deviation above or below the mean. This group of children is called the “middle of the bell curve” or average range.

So, does your child have clinically significant features of inattention? It depends on how much his behavior or problems differ from the mean. Behaviors that deviate from the norm by more than two standard deviations (less than about 5% of the children) are generally labeled as having features that are clinically significant or important. While the presence of clinically significant or important features of inattention (more prevalent than about 95% of children) is important to know, it still does not nail down an ADHD diagnosis.

My point? Objective measurements of behaviors or problems with subsequent comparison to age norms (bell curves by age) is the first step in understanding whether a behavior is a clinically significant issue. In the absence of standardized observations and normative comparisons, the diagnostic process boils down to the “mean” and “standard deviation” that that the professional has in his or her head based on clinical experiences. Maybe part of our confusion regarding diagnostic processes is because each clinician develops his or her own norms (means) including normal ranges (standard deviations) without recognition of their inherent bias.

Do your child’s behavior problems fall within the norm? Does your child still drive you crazy even if it’s not clinically significant? Hmmmm…the doctors and nurses should also have told you about that part too!

dyslexia as being a visual problem

“My child can’t read… and the school told me its because he has dyslexia… he reverses his letters and they said that he gets the letters all jumbled. They said that it had something to do with his vision and as a result, he can’t read. Now what? Do we get an eye examination?"

Hmmmm… letters jumbled up meaning that you can’t raed? Are you albe to raed this eeven thugoh the ltteres are all mxied up? Aoccdrnig to rscheearch at Cmabrigde Uinervtisyity, ltteer odre deos not mttaer… the iprmoatnt ptar is taht the frist and lsat ltteer be in the rghit pclae… the rset can be a taotl mses and you can sitll raed it wouthit a porbelm. So… is dyslexia related to letters being jumbled up? Is dyslexia a disturbance of visual configurations of letters?


Research (see Dr. Jack Fletcher) among children reveals that phonetic or speech sounds processing is the most commonly the primary underlying disorder in dyslexia. Other contributing factors to low achievement in reading (or dyslexia which means a disturbance in reading) include low vocabulary and limited experience with reading (ie., few repetitions, insufficient time spent reading, etc.). Need to rule out reduced visual acuity as a contributor to slowed reading, headaches in the afternoon… by all means, please get an eye examination. But, dyslexia as being a visual problem? Hmmmm… maybe not.

So, how do I know if my child has dyslexia”? Well, dyslexia simply indicates a disturbance in reading… Is your child reading significantly below the level of his or her peers? If so, then he or she has dyslexia or a reading disorder. Unfortunately, dyslexia or the formal diagnosis of a reading disorder does not communicate anything beyond the symptom description. The real task is identification of factors that contribute to reading problems. In the past, various models have been employed to classify reading disorders with the discrepancy model holding court for the past 25+ years. The discrepancy model defines a reading disorder in terms of a significant discrepancy between reading achievement (lower) and abilities (higher) with some suggestion or assumption of a significant verbal (lower) vs. perceptual-motor (higher) processing discrepancy.

However, recent reviews of research (see Fletcher, J.M., Francis, D.J., Morris, R.D. and Lyon, G.R.. “Evidence-based assessment of learning disabilities in children and adolescents”, Journal of Clinical Child & Adolescent Psychology, 2005, Vol. 34, No. 3, Pages 506 – 522) indicates that this model has serious psychometric problems (meaning research cannot reliably replicate it). More recent work suggests that, while low reading achievement is the critical element for classification as a reading disorder (by definition), an evidence-based assessment must include an analysis of reading components (ie., see, discriminate letters, associate letters to sounds, put sounds together to make words, put words together to form sentences/ideas, formulation of themes and output) so that interventions are directed towards the weakest link in the chain of reading.


In addition, the work of Fletcher, et. al. (2005) calls for “a stronger underlying classification that takes into account relations with other childhood disorders” including a need for assessment of abilities (hardware), skills (acquired) and coping resources (ie., family support, teachers, educational instruction, etc.).
