Friday Factoids Catch-Up: Attention Deficit Hyperactivity Disorder (ADHD)

Attention Deficit Hyperactivity Disorder (ADHD) has been a hot topic for some time now and more and more children are being diagnosed with ADHD than ever before. Lunau (2014) quoted Enrico Gnaulati by writing that an ADHD diagnosis is “as prevalent as the common cold.” If this is the case, how do we, as clinicians, respond to this phenomena?

 

Lunau noted that more than one in ten children are diagnosed, typically, boys. (Lunau 2015) In her research, she look at various states and how each approached the diagnosis and subsequent treatment of ADHD.  She brought forward information regarding North Carolina and California to elucidate the vast differences how one can approach ADHD. She noted a 16 % diagnosis rate for children in North Carolina, whereas California has a 6%; she also discovered that children in North Carolina were 50% more likely to receive medications as treatment for ADHD symptoms.  Lunau looked to the work of Hinshaw and Scheffler (reference information not provided in Lunau’s work) who explore the multiple variables that may impact these statistics, including demographics cultural influences, and health care policy. Ultimately, they discovered that school policy has the largest impact.

 

Specifically, school mandates in North Carolina for higher test scores may have impacted the perceived need for some children to receive additional services and, in some cases, children receiving academic based services are not included in the test score average (Lunau, 2015).

 

So, given the significant difference between the incidences of ADHD across state, are we witnessing an epidemic or a cultural phenomena that carries with it a secondary gain of medication management to attempt to manage behaviors or increase school testing scores. Taking a step back and looking at ADHD from a global perspective, Lunau noted other countries are not experiencing a similar increase in the onset of ADHD in their children and briefly explored how other factors may mimic ADHD symptoms, like sleep deprivation.  Though briefly mentioned, Lunau indicated the need for further exploration into how ADHD is assessed and diagnosed.

 

When looking at the high rates of ADHD, we must also begin to consider how this diagnosis is treated. Is medication the ideal treatment?  The CDC published a study (PR, 2015) which looked at the various types of treatment our children are exposed to.  Results indicated 1 in 10 children, ages 4-17, diagnosed with ADHD received behavioral therapy, 3 in 10 received medication and therapy, and 1 in 10 received no treatment. When looking at preschool aged children, 1 in 4 received medication alone and 1 in 2 received both medication and therapy.  This begs the question of whether or not we are over medicating our children so early in life. What are the long term implications of medication only interventions on the overall development of the child?

 

The CDC study highlighted that states which provided increased amounts of behavioral therapy also experienced lower rates of medication management for the treatment of ADHD, and vice versa. Bell and Efron (2015) briefly explored the impact of tri-cyclic antidepressants as a possible treatment for children with ADHD and noted tricyclic outperformed, in one trial, clonidine in the reduction of symptoms.  The information in these three articles is obviously not exhausted, however, it does highlight the need for continued research in the assessment, diagnosis and treatment of ADHD and an active re-evaluation of how cultural/social influences can impact the national conversation of how we understand ADHD.

Friday Factoids: Does the “H” in ADHD Really Impair Learning?

Recent models of Attention-Deficit Hyperactivity Disorder (ADHD) have challenged the notion that excess gross motor activity (hyperactivity) impedes learning with children diagnosed with ADHD.  Rather, newer models argue that excess motor activity may be compensatory.

 

A recent study conducted by Saver, Rapport, Kofler, Raiker, and Friedman (2015) compared 29 boys diagnosed with ADHD to 23 boys with no psychiatric diagnosis on a series of working memory tasks (i.e., participants were shown numbers and letters on a computer screen and asked to order them, while being recorded on a high speed camera for later behavior/movement coding).  The data indicated higher rates of gross motor activity positively predicted phonological working memory performance in children with ADHD.  Such was not seen in children with no psychiatric diagnoses.  In fact, boys with no ADHD diagnosis with increased movement performed more poorly on the cognitive tasks.  Thus, indicating a link between hyperactivity and task performance in children with ADHD.

 

Saver et al. (2015) conclude that excess movements are necessary to how children with ADHD remember information and process cognitive tasks.  The implications here are vital to recommendations given specific to behavioral intervention and current classroom management of behavior for children with ADHD.  In that, if these findings are confirmed, the authors caution against overcorrecting excess gross motor activity for children with ADHD.   Such activity may even be reinforced during select academic tasks.  Of course, the authors do not recommend allowing extreme movements (e.g., running around the room); rather they argue to facilitate movement in order to maintain alertness to complete cognitive tasks (University of Central Florida, 2015).

 

These findings implicate that past behavior plans and expectations/goals of reduced activity may be misguided, instead movement perhaps should be permitted in order to maintain alertness.  Overall, data support a new conceptualization that gross motor activity may facilitate cognitive functioning for children with ADHD, rather than impair it.  This research is limited by only sampling boys ages 8-12.  It is further limited by only assessing phonologically based activity; future research is anticipated to look at the impact of hyperactive movement in relation to visuospatial working memory (Saver, Rapport, Kofler, Raiker, & Friedman, 2015).  Overall, these finding again support new models of ADHD that conceptualize excess motor activity as compensatory.
