ADHD & The Fountain of Youth

A recent study published in the journal PLoS ONE reveals how we can all look younger and decrease cognitive deficits like ADHD. The secret:  exercise! That’s probably not what you want to hear, but it makes sense.

Scientists at Tel Aviv University found that "endurance exercises," aerobic exercise like running or cardio kickboxing not only help burn fat, but can also make us look younger and decrease symptoms of cognitive decline.

The team at Tel Aviv University’s Sackler School of Medicine led by
Prof. Dafna Benayahu propose that their data reveal why older people who have exercised throughout their lives age more gracefully.

"When we age, we experience sarcopenia, a decline in mass and function of muscles, and osteopenia referrers to bone loss," says Dr. Benayahu. So without daily exercise, the muscular and skeletal systems weaken and are more susceptible to injury. This may also play a role in the increased likelihood of falling as we age.

The key to staying young seems to lie in stem cells that get activated during endurance exercise. To determine this, Benayahu and her team studied rats. Basically, making the rats exercise actually increased the number of muscle stem cells that typically decrease as we age.

The results were quite compelling when contrasting rats that exercised against sedentary rats:
* The number of youth producing stem cells increased after rats ran on a treadmill for 20 minutes a day for a 13-week period.
* The younger rats showed a 20% to 35% increase in the average number of stem cells per muscle fiber retained.
* Older rats attained a 33% to 47% increase in stem cells meaning they benefited even more significantly than the younger rats!
* Endurance exercise prompted the older rats to get up and go more often!

Aging while embracing a sedentary lifestyle significantly contributes to the development of disease. Furthermore, it contributes to a decline in cognitive abilities.

In other previous studies, researchers have also found that exercise in outdoor or ‘green’ settings reduces the symptoms of ADHD.

What’s the future? Well, it’s likely that scientists will try to discover the chemical process behind  stem cell activation to produce more youthful bodies. It  can then be sold as a pill. It seems the world would rather do that than just get up and dance! And no side-effects except sore muscles that are getting stronger, more youthful, and defined!

Does this ADHD make me look fat?

Ever think that your ADHD child likes to dip into the cookie jar more than the average child? You may be right according to research reported in the International Journal of Obesity (26 October 2010| doi:10.1038/ijo.2010.214) .

Researchers at Duke University Medical Center found an interesting correlation: the greater the number of ADHD symptoms, the greater risk of obesity later in life.

They examined data extracted from 15,197 respondents from the National Longitudinal Study of Adolescent Health in the US. The Duke researchers attempted to assess the association between ADHD symptoms and naturally occurring changes in body mass index (BMI) from adolescence to adulthood. The data were collected over the years 1995 until 2009.

"This is the first study to take this concept out of the clinic and into the population and show that it’s not just the diagnosis of ADHD that matters; it’s the symptoms," said study co-author Scott Kollins, adding, "The most exciting thing about this research is it gives us a thread to follow in determining why kids with ADHD symptoms might be at risk for developing obesity. It establishes the path for identifying these kids earlier and focusing on intervention methods."

It’s well established that ADHD kids have impulse control issues. We also know that foods high in fat, sugar, and calories have the same reaction on the brain’s reward systems as stimulant drugs. This combination could likely cause higher BMI as a child ages.

To be forewarned is to be forearmed. It’s likely good parenting to closely observe your child’s impulse control and assist your child to control food intake as he ages. It’s also a healthy idea to limit consumption of high fat, high sodium, and sugary foods.

Training the ADHD Brain

For years, we at Play Attention, have trained thousands and thousands of people to better pay attention, learn the cognitive skills they need to succeed, and change their behavior. Our results have spoken clearly for us since 1994. Now science is catching up.

Two recent distinct studies validate the brain’s ability to change. While a vast plethora of research confirms these studies’ findings, they are noteworthy. The first study demonstrates the efficacy of skill training, and the second demonstrates how teaching skills rewires the living brain.

The first study, published in the August 25 Journal of the American Medical Association, was performed by researchers from Massachusetts General Hospital (MGH). They utilized cognitive behavioral therapy as a direct intervention for ADHD adults. Cognitive therapy teaches skills for managing life challenges.

The researchers at  MGH found that while medications were the first line of treatment, many patients still persist with underlying symptoms.  While previous studies on cognitive behavioral therapy for ADHD were small and short term, the researchers at MGH claim their study to be the first to conduct full-scale randomized, controlled trial of the efficiency of an individually-delivered, non-medication treatment of ADHD among adults.

“Medications are very effective in ‘turning down the volume’ on ADHD symptoms, but they do not teach people skills,” commented Steven Safren, PhD, ABPP, director of Behavioral Medicine in the MGH Department of Psychiatry, who led the study. “This study shows that a skills-based approach can help patients learn how to cope with their attention problems and better manage this significant and impairing disorder.”

“Sessions were designed specifically to meet the needs of ADHD patients and included things like starting and maintaining calendar and task list systems, breaking large tasks into manageable steps, and shaping tasks to be as long as your attention span will permit,” commented Safren, an associate professor of Psychology in the Harvard Medical School Department of Psychiatry. “The treatment is half like taking a course and half like being in traditional psychotherapy.”

Like Play Attention has been doing since 1994, the researchers provided training sessions mainly that included skills training in filtering of distractions, organization, problem solving, and planning.

Safren’s group receiving cognitive and behavioral training demonstrated advanced control of their symptoms over their control group.  This benefit had persisted when measured three and nine months after the training.

The second study, published in The Journal of Neuroscience (August 25, 2010, 30 34 11493-11500 doi 10.1523 JNEUROSCI.1550-10.2010), examined the brains of rats when they learned to control their impulses.  The researchers documented synaptic changes in the medial prefrontal cortex. They concluded that the rat’s brains rewired themselves to produce the impulse controls necessary to be successful in the tasks the scientists had established for them.

Other past studies have confirmed that the brain will rewire to make changes for skills, impulse control, organization, etc. We’re glad that science is catching up to an learning process that we’ve done at Play Attention for sixteen years now.  That’s beyond cutting edge; it’s leading the way for others.

Misdiagnosing ADHD

According to a study released by the University of Michigan, nearly 1 million children in the United States are potentially misdiagnosed with ADHD.

The research was conducted, not by a medical group, but by economist Todd Elder  in the Journal of Health Economics (Elder et al. The importance of relative standards in ADHD diagnoses: Evidence based on exact birth dates. Journal of Health Economics, 2010; DOI: 10.1016/j.jhealeco.2010.06.003).

Elder found that the youngest or often the most immature children are misdiagnosed with the ADHD label simply because of their age and exhibited maturity. Elder also found that these children are significantly more likely than their older classmates to be prescribed medications like Ritalin to control their behavior. Using a sample of 12,000 children, Elder examined the difference in ADHD diagnosis and medication rates between the youngest and oldest children in a grade. He found that the youngest kindergartners were 60 percent more likely to be diagnosed with ADHD than the oldest kindergarten children. Elder followed that group of children and found that they were more than twice as likely to be prescribed stimulant medication by the time they reached the fifth and eighth grades.

Currently, about  4.5 million children are diagnosed with ADHD. Elder concludes that about 20 percent  or about 900,000 children have likely been misdiagnosed.

In a press release from the University of Michigan, Elder said that such inappropriate treatment is particularly worrisome because of the unknown impacts of long-term stimulant use on children’s health. Elder is also concerned that misdiagnosis wastes an estimated $320 million-$500 million a year on unnecessary medication. He estimates that between $80 million-$90 million of it is paid by Medicaid.

"If a child is behaving poorly, if he’s inattentive, if he can’t sit still, it may simply be because he’s 5 and the other kids are 6," said Elder. "There’s a big difference between a 5-year-old and a 6-year-old, and teachers and medical practitioners need to take that into account when evaluating whether children have ADHD."

ADHD has no pathology, no biological marker in the brain that clearly demonstrates its existence. Thus, its diagnosis is always subjective. While teachers are not permitted to make this diagnosis, their perceptions and opinions serve as the initial step to a diagnosis made by a doctor.

"Many ADHD diagnoses may be driven by teachers’ perceptions of poor behavior among the youngest children in a kindergarten classroom," he said. "But these ‘symptoms’ may merely reflect emotional or intellectual immaturity among the youngest students."

According to Science Daily, Elder’s paper will be published in the Journal of Health Economics in conjunction with a related paper by researchers at North Carolina State University, Notre Dame and the University of Minnesota that arrives at similar conclusions as the result of a separate study.

ADHD and dropout rates

The July issue of the Journal of Psychiatric Research reports a study by the University of California, Davis. The researchers examined whether ADHD could be predictive of failure to graduate high school on time.

When the UC Davis scientists reviewed different types of ADHD, they found all of the types of ADHD are associated with a high dropout rate.

"The study found almost a third (33%) of students with ADHD, don’t graduate with their peers. That’s high compared with the national high school drop out rate of 15 percent. High school dropout rate really is a national crisis. We know that a third of kids nationally who start in ninth grade don’t graduate in four years," says  lead study author Dr. Joshua Breslau.

The researchers conducted structured diagnostic interviews with a US national sample of adults (18 and over). The interview process also correlated smoking and smokeless tobacco use. According to the National Institute of Health, nearly a 25% of high school students in the U.S. smoke cigarettes and another 8% use smokeless tobacco. The study found that students who use alcohol, smoke cigarettes and use other drugs are more at risk to drop out.

"There are really two main disorders, ADHD and conduct disorder, and there is an interlinking of smoking and drop out that is troubling…it really suggests that socioeconomic differences in health are already becoming established very early in life in adolescents…whether they smoke is probably the biggest indicator of their health in adulthood," said Breslau.

Intuitively, as parents and educators, we know this to be true. We have seen it in other families too. Intuitively we also know that we must do something as education and medicine alone fall far short.

Cognitive training, behavioral shaping, memory skills, and more must be instituted if we are to change the tide.

Is ADHD all in your head?

A study published in the June 14 edition of the Journal of Developmental and Behavioral Pediatrics has sparked controversy regarding ADHD medication and the brain’s power to regulate itself.

The study was funded by the National Institutes of Health and conducted by Dr. Adrian Sandler, a developmental-behavioral pediatrician and medical director of the Olson Huff Center for Child Development at Mission Children’s Hospital in Asheville, North Carolina.  The research was performed over the course of eight years using 99 patients from Western North Carolina.

Sandler found that children with ADHD can do just as well on half their medication when the medication is combined with a placebo. They performed as well even when parents and children had full knowledge they were taking a placebo.

[Placebo --  A substance containing no medication and prescribed or given to reinforce a patient's expectation to get well. The placebo in this research was akin to a harmless inert pill].

Previous studies have shown that common stimulant medication causes side-effects like tics, weight loss, stunted growth, and even heart complications in some instances. This often causes trepidation in parents afraid of the possible side-effects on their children.

Sandler compared fully medicated children, children on reduced medication, and children on reduced medication with a known placebo. The results were quite intriguing.  Both the fully medicated and reduced medication groups had increased side-effects while the reduced medication with placebo demonstrated decreased side-effects. Furthermore, the reduced medication group reported decreased control of their ADHD symptoms. However, the control of ADHD symptoms was no different in the reduced medication with placebo group than in the full dose group, i.e. the reduced medication with placebo performed as well as the fully medicated group with less side-effects as well.

“I’ve been getting a lot of calls and e-mails,” said Sandler,, who conducted the research with James Bodfish, a professor in the departments of psychiatry and pediatrics at UNC Chapel Hill School of Medicine, and study coordinator Corrine Glesne.

“Medications work,” Bodfish said in a statement. “The question is whether we always need to use them at the highest dose. Many parents are concerned about placing their child on medication. Some choose not to treat their child because of concerns about side effects.”

While the research doesn’t address it, the obvious question is, Why? Parents and children in this study knew they were taking a placebo. Why then did they perform as well as their peers without the side-effects — at essentially half the dose as their peers? While the placebo effect has been studied widely, the exact mechanisms are unknown. We do know that the mechanism is governed by the brain. This clearly tells us that having ADHD or not, our brain is still a powerful weapon in our arsenal.

We also cannot exclude the influence of the parents during this research. Did they expect their child to do better? The authors suggest that this was so. This dynamic cannot be overlooked in your family either.

The bottom line is that we likely have far more control over our behaviors and cognitive processes than we are given credit for. Modern medicine, as this research suggests, is just beginning to understand the brain’s role in shaping our lives. We’ve known this for years at Play Attention. Cognitive training. Memory training. Motor skills. Attention training. Behavioral shaping. It’s time to take control over our lives. We’ve all got the power to do it. It lies right behind our eyes.

The ADHD link to social dynamics

If I told you that women who received only basic education were 130 % more likely to have a child on ADHD medication than women with university degrees, you’d see a link, wouldn’t you? 

Well, that’s what a  study published this month in Acta Paediatrica found.  That implies that nearly half of the serious cases of ADHD  in children are closely tied to social factors. The study reveals that factors like single parenting and poor maternal education were directly tied to ADHD medication use.

While we know that a genetic propensity likely exists, the human brain develops based on a complex interplay between nature and nurture; between genetic endowment (nature) and environment/social factors (nurture). Epigenetic theory tries to explain this relationship.

Curiously, few large-scale studies have tried to determine the impact of social and family influences on ADHD. Researchers at the Karolinska Institute in Stockholm, Sweden assessed data on 1.16 million school children and examined the health histories of nearly 8,000 Swedish-born kids, aged six to 19, who had taken ADHD medication.

"We tracked their record through other registers … to determine a number of other factors," said lead author Anders Hjern.

Here’s what the researchers found:

  • Living in a single parent family increased the chances of being on ADHD medication by more than 50 percent.
  • A family on welfare upped the odds of medication use by 135%.
  • Boys were three times more likely to be on medication than girls.
  • Social dynamics affected both sexes equally.

"Almost half of the cases could be explained by the socioeconomic factors included in our analysis, clearly demonstrating that these are potent predictors of ADHD-medication in Swedish school children," Hjern said.

It’s clear that this study found a link between socioeconomic factors and ADHD medication use/diagnosis. Other US studies have found that minority children and children of low socioeconomic status were more likely to receive ADHD medication.

Factors like low income and diminished quality time are more common in single-parent families. These typically lead to stressors like family conflict and a lack of social support, Hjern said.

While more research must be done, one has to ask, is medication the answer to social stressors like lack of time and money? Sounds too silly to ask, but it seems that our answer, ridiculously, is a resounding, YES!

We are the masters of our lives. We can make significant personal changes, but we must have the tools to do so. That’s why I began Play Attention (www.playattention.com) years ago.

Immediate rewards and the ADHD brain

A Nottingham University research team in the United Kingdom found that the brains of children with ADHD appear to respond to immediate rewards in the same way as they do to medication. Their research was published in the journal Biological Psychiatry.

“Our study suggests that both types of intervention [medicine and immediate reward/reinforcement] may have much in common in terms of their effect on the brain,” said Professor Chris Hollis, the lead investigator of  the study.

The research team used an EEG (electroencephalograph) to measure the brain activity of children as they played a computer game that provided extra points for less impulsive behavior.

The researchers devised a computer space game which rewarded the ADHD children when they caught aliens of specific colors  while avoiding aliens of designated colors. The game design actually tested the children’s ability to resist the impulse to grab the wrong colored aliens.

To test whether immediate reward/reinforcement made a difference, one iteration of the game rewarded the children fivefold for catching the right alien and penalized them fivefold for catching the wrong one.  All of this was done while activity in different parts of their brains was monitored with an EEG.

Hollis found that the immediate rewards helped the children perform better at the game. This was verified by the EEG which  revealed that both medication and immediate reward/reinforcement were "normalizing" brain activity in the same regions.

Many parents of ADHD children are aware that giving a reward to an ADHD child a week after their good behavior is insignificant to that child. ADHD children respond better to immediate reward, not delayed reward.

"Although medication and behavior therapy appear to be two very different approaches of treating ADHD, our study suggests that both types of intervention may have much in common in terms of their effect on the brain. Both help normalize similar components of brain function and improve performance,"  said Hollis.

"We know that children with ADHD respond disproportionately less well to delayed rewards – this could mean that in the ‘real world’ of the classroom or home, the neural effects of behavioral approaches using reinforcement and rewards may be less effective."

It’s obvious that providing immediate rewards/reinforcement 24 hours a day and 7 days a week would be impractical and impossible. But what does this research tell us? It tells us that if we are to train an ADHD student, feedback, reward, and reinforcement need to be immediate if we are to get their brain to rewire.

We at Play Attention have known this for many years. This is why we integrated immediate feedback/reinforcement for attention training, cognitive training, memory training, and behavioral shaping by using feedback technology. We patented this method years ago because of its inherent strength. While we knew this was the best way to achieve success, we feel research like this rather reinforces our approach. It’s about time the world caught up!

Sleep Disorders & ADHD

It’s suspected that nearly 25% of all cases identified as attention deficit hyperactivity disorder (ADHD) are not really ADHD at all, but are symptoms related to sleep disorders.

One of the leaders in this research is University of Michigan professor Ronald Chervin.  Chervin theorizes that very important brain development is done during sleep. Among other things, this includes the ability to regulate emotion and processing. So, if a child has chronic sleep problems, brain development may be impaired. Chervin also suspects that the brain does not receive enough oxygen if the child snores which further inhibits development.  According to Chervin’s research, children who snore are more likely to have ADHD.

He likens the ADHD-sleep connection to a child who doesn’t get a nap; he becomes restless, irritable, and acts out.

Chervin developed his theory based on a sleep/behavior survey of the parents of 866 children.  Chervin’s data exposed a sleep disorder -behavior relationship.  It was only logical to conclude that if the sleep disorder could be corrected, the ADHD symptoms would be extinguished. 

According to Newsweek: “To test this theory, Chervin then studied 79 kids (5 to13 years old) who were about to have an adenotonsillectomy. Prior to the surgery, 22 of the 79 were categorized as having ADHD, based on standard measures for such a diagnosis. One year later,  Chervin’s team tracked down the kids for a follow-up. Of the 22 identified as having ADHD, 11 kids no longer qualified as having the disorder.”

Two problems lingered: 1) New cases of ADHD cropped up and 2) 50% of the surgical patients received no benefit at all.

Before you go and get your child’s tonsils and adenoids out, let’s discuss the distinct problems in the logic associated with this research.

First, we have a problem of antecedence; does ADHD exist because of sleep problems? or does the sleep problem exist because of  ADHD? That relationship cannot be clearly identified and is a confounding problem.

Secondly, new cases of ADHD appeared and others did not benefit at all from the surgery. This would lead one to think that the outcomes may not be related at all to the procedure.

I’m reminded of an old story about researchers who taught a frog to jump upon saying, “Jump!” Many weeks were spent training the frog.  The researchers were quite happy that they had proved the frog could hear and could respond to the human voice. One of the researchers  decided they should amputate the frogs hind legs. After carefully surgically removing the frog’s legs and rehabilitating the poor frog, the researchers stood in front of the frog and yelled, “Jump!” When the frog did not respond, they all heartily nodded in agreement that the frog’s hearing was severely impaired by the removal of his hind legs.

There is little doubt that sleep problems affect brain development. Past studies have demonstrated that preschoolers with a sleep disorder are twice as prone to substance abuse by early adolescence and more likely to suffer from anxiety in their 20s. Even the American Academy of Pediatrics concurs that sleep problems are not benign.

However, before we undertake invasive, painful surgery as an option, far more research should be performed to absolutely indicate a direct correlation. One currently does not exist and other options should be explored. playing241

It has become obvious that adequate, restful, uninterrupted sleep is essential to our personal well being. Abnormal sleep patterns may result in behaviors that can be easily confused with ADHD.

If your child has a sleep problem, taking them to a sleep specialist may help. Getting adequate exercise, providing a consistent sleep routine/schedule, reducing stress,  and eating a proper diet may also assist in getting better sleep and better behavior.

  • Dopamine & ADHD

    thinkingm4  The Journal of the American Medical Association (JAMA. 2009;302(10):1084-1091) recently published work by Dr. Nora D. Volkow, MD, et al regarding evaluation of the biological bases that may reveal a reward/motivational deficit present in the brains of persons with ADHD.

    Volkow and her colleagues theorized that ADHD may be connected to reward-motivation deficits. Volkow investigated whether lack of motivation and its relationship to reward could be traced to depression of dopamine in various areas of the brain.

    To determine whether dopamine was depressed in ADHD persons, the researchers used positron emission tomography (PET scans) to measure dopamine levels in 53 nonmedicated ADHD adults and 44 healthy non ADHD adults between 2001-2009.

    Since the biological mechanisms of ADHD are unknown, studies of this type have become the holy grails of research. While Volkow’s credentials are quite impressive (NIH, NIDA, etc.) this research is not new or conclusive. The theory that dopamine dysfunction/depression may be involved with ADHD symptoms has been researched for many years.

    Furthermore, Volkow’s  small sample size consisted only of adults and therefore should not be extrapolated to include the child population. The small sample size alone should prevent it from being generalized to the entire adult ADHD population. One has a problem of antecedence here; is ADHD caused by dopamine depression in the brain? Or is the dopamine depression the result of ADHD that was acquired by other biological means? This research cannot answer that question.

    What does the research tell us? It tells us that for some adults, dopamine may play a role in ADHD. For those adults, taking a stimulant medication may increase dopaminergic activity thus increasing reward/motivation responses and thus increasing attention to task. That might be a stretch.

    On the downside, persons with depressed dopamine levels would probably greatly enjoy using stimulants. Study participants reported this. This may contribute to the frequent incidences of substance abuse among ADHD persons.

    The authors write,"Despite decades of research, the specific neurobiological mechanisms underlying this disorder still remain unclear. Genetic, clinical and imaging studies point to a disruption of the brain dopamine system, which is corroborated by the clinical effectiveness of stimulant drugs (methylphenidate hydrochloride and amphetamine), which increase extracellular dopamine in the brain."

    Unfortunately, the study leaves us with more questions than answers. Does it tell us what happens long term? Does it tell us of side effects?  Does it tell us if this actually applies to children? Can we conclusively determine a causal relationship between reward/motivation and ADHD? Does it solve the problem of antecedence? Do we know anything conclusively about all ADHD adults. No. There’s still a long road ahead.
