Despite knowing the immense benefits of school attendance, many parents can relate to the battle that ensues when trying to get their child ready for school. Parents of children with attention-deficit / hyperactivity disorder (ADHD) might ask themselves, ‘what can I do to increase my child’s attendance at school?’. Parents may worry that their child’s absence at school due to school requests to stay at home, problematic behaviours, school refusal etc. will affect their child’s academic performance. Such concerns are warranted as school attendance is generally considered essential for academic progress, which is a powerful social determinant of health and long-term educational attainment. Research findings that children with ADHD are 3 times more likely to be held back a grade and 2.7 times more likely to drop out of high school before graduation (Barbaressi et al., 2007) highlight the importance and urgency of this issue. In this blog post, I aim to explore school absence from the perspective of a researcher and offer some insights into whether parents being more involved in their child with ADHD’s education is the key to improving their school attendance.

Is not attending school really that bad?

For parents, allowing their child to miss a few days of school may seem like a solution to the meltdown or emotional outburst at hand, but it might be the beginning of a pattern of school absence. School absenteeism, which is defined as missing 10 percent or more of the school year (Gottfried, 2019) is an important social determinant of health that has been greatly understudied in children with ADHD. Of the approximately 194 school days in a year, that is 19.4 days of learning and opportunities for social and emotional development that are missed. Research suggests that children and youth with ADHD, particularly boys, miss more school compared to their peers without ADHD (Classi et al., 2012; Kent et al., 2011; May et al., 2021). This may pose a significant challenge for the education of these children. The educational journey of children with ADHD can be fraught with difficulties due to cognitive challenges such as impairments in memory functions, increased distractibility, and slow thought processing speeds (Mohammed et al., 2021). These difficulties already heighten children with ADHD’s risk of underachievement, but when combined with chronic absenteeism, these children may struggle with reaching their true academic potential. But, why are these children missing more school than their neurotypical counterparts? There are a myriad of reasons why a child is absent from school, but research has shown that 41% of these reasons are parent driven for typically developing children (Hancock et al., 2018). For neurodivergent children, the answer to this question is less clear. Considering the research suggesting that supportive parental involvement education is associated with academic achievement in children with ADHD (Rogers, 2009a), addressing school absence may require focusing on parents to reduce these absences.

Is parental involvement in schooling beneficial for children with ADHD?

As a neurotypical child, I recall dreading parent teacher meetings because of how involved my parents were in my education. While their absence was missed at school events because of their busy schedules, my parents made it a point to know when I had tests, how I felt about each school subject, the friends I hung out with at lunch and what extracurricular activities I liked. Previously, their interest seemed excessive, but the more I research the benefits of parental engagement in schooling, the more grateful I am for their involvement. Families with children with unique learning needs, such as those with ADHD may struggle in these areas. I asked my aunt to describe what navigating the school system is like with a child with ADHD. She said, and I quote, “Being a mom of a child with ADHD is tough...I’m always worried he’s being left out...I try to stay involved, but it feels like I’m constantly at loggerheads with the school.”

Parental involvement implies a parent’s dedication of resources such as time and effort for their child’s development. Parental involvement encompasses a wide range of behaviours performed at home or school, from homework-helping (home-based parental involvement) to participation in school activities (school-based parental involvement). There is a plethora of benefits of parental involvement in education for both youth with and without ADHD. For example, in children with ADHD, supportive parental involvement is related to higher academic achievement (Rogers et al., 2009c). However, it seems that there may be obstacles for parents of children with ADHD to reaping these benefits. According to research, parents of children with ADHD perceive more teacher demands than parents of children without this diagnosis (Rogers et al., 2009). Given the inattentive behaviours commonly seen in these children, it might be that parents are interpreting comments made by teachers about their child with ADHD’s behaviour as excessive demands on their time and energy, which may already be depleted. It is conceivably difficult for parents of children with ADHD to foster positive relationships with their child’s teacher and attend school events when they do not feel welcome.

So, how can parents and teachers get around this obstacle? A practical method that has demonstrated its effectiveness for youth with ADHD in research is the use of a daily report card (DRC) system (Iznardo et al., 2020). A DRC system involves setting behavioural goals which are monitored daily by teachers. Information is recorded on the child’s ability to meet said goals. Parents sign the report card at the end of each day and when a child’s reaches a predetermined level of success, they are rewarded. This system proactively addresses behavioural problems and may improve communication between families and schools by building positive rapport and providing parents with opportunities for school-based involvement. Clearly, school-based parental involvement and parent-teacher relationships are both significant for children with ADHD’s schooling, but is this the answer to the high rates of chronic absenteeism seen in this population?

Is parental involvement the missing puzzle piece?

The short answer is maybe. There is no one overarching answer to school absenteeism in children with ADHD. The solution to school absence is just as complex and varied as the reasons for school absence. The long answer is that targeting chronic absenteeism may require a four-pronged attack involving not just parents but also educators, practitioners, and policymakers. The paucity of literature on this topic, necessitates further research on the link between parental involvement in education and school attendance in children with ADHD to inform interventions and programs that seek to improve absenteeism. My current research explores this very question, so I hope to add to the knowledge on this topic. While I cannot presently answer whether parental involvement is the key to improving school attendance in children with ADHD, investing time and being more involved in your child with ADHD’s education is certainly a step in the right direction.

While ADHD is a neurodevelopmental condition that affects a significant number of children and adults, those with the diagnosis are still subject to a high degree of stigma and misunderstanding. This lack of respect for ADHD as a legitimate disability also translates to a lack of proper support and treatment. Myths and misinformation still abound about ADHD even though abundant scientific evidence exists documenting the structural and chemical differences in ADHD brains. The short and long-term negative impacts on ADHD children when they don’t receive appropriate treatment can be significant and life-changing (Di Lorenzo et. al., 2021). Very capable individuals can end up living a lifetime of lost potential.

Misunderstanding of ADHD Children and Adolescents

While inattention, hyperactivity, and impulsivity are considered the hallmark features of ADHD for diagnosis, seeing these three symptoms as the basis of ADHD is a far too simplified view of this condition. A defining feature also includes weak executive functioning skills which influence the ability to plan and organize, manage time and schedule, regulate emotions, and start and complete tasks. These weaknesses influence not only academic performance but behaviour and social functioning. For example, the majority of ADHD children and adolescents have difficulty regulating emotions which can lead to more explosive emotions and disruptive behaviours. Learning to regulate emotions is a skill that needs to be taught and developed over time. However, a child is often given repeated negative consequences from behaviour stemming from emotional dysregulation which does nothing to help the child build the necessary skills. The understanding that behaviour is not always wilful or within the child’s control is key to better supporting challenging behaviour in ADHD children. Too often I hear about ADHD children being pulled out of classrooms and sent to the principal’s office due to this dysregulation. Unfortunately, this is often the opposite of what these children need to learn to regulate. Instead, they need supportive, regulated adults who can connect with these kids, build safety, and help them to learn regulation skills.

Lack of School Support

Unfortunately, according to CADDAC’s own 2021 Provincial Report Card: ADHD in the School System, there is a pattern of inconsistent and inequitable educational support for students with ADHD when compared to other neurodevelopmental conditions. The provinces of Ontario, British Columbia, and Quebec received a failing grade due to students being withheld special education services unless there is an existing co-morbidity that is eligible (e.g., learning disability, or a mental health or behaviour designation). Unless students with ADHD are recognized as having a disability, they are not automatically eligible for an individualized education plan (IEP) to ensure they get the appropriate classroom accommodations and learning support. This has undoubtedly contributed to many teachers having the perspective of ADHD being a behavioural issue rather than a legitimate neurodevelopmental condition requiring specific learning support. It was notable that across all provinces there was insufficient educator training about ADHD. Sadly, academic underperformance is one of the long-term consequences of ADHD (Arnold et. al., 2020).

The Cost of Misunderstanding

Lack of proper recognition and awareness of the realities of ADHD takes a huge toll on the emotional well-being of ADHD children and adolescents. Anxiety and depression are common co-morbidities in ADHD children and adolescents (Gair et al, 2020; Meinzer, et. al., 2014). ADHD children and adolescents receive a highly disproportionate amount of criticism compared to their non-ADHD peers, and there is some evidence to show they also may be more sensitive to negative consequences (Furukawa et. al, 2017). We also know that shame results from repeated experiences of not meeting expectations and leads to ADHD children and adolescents feeling less than or unworthy compared to their peers. I am deeply saddened when I meet parents and educators who still hold the belief that ADHD children just need to try harder. This leads to these children feeling frustrated, deflated, and hopeless. What they need instead is a new strategy or a different accommodation, and an acknowledgment of how hard they are already trying. In fact, children and adolescents with ADHD are likely already trying harder than many of their neurotypical peers due to the additional mental effort it takes them to accomplish the same tasks.

In addition, and in line with what I see in my practice, research has documented high levels of stress in parents raising ADHD children. Specifically, mothers of ADHD adolescents reported the highest stress, the lowest sense of competency in their parenting skills, and the highest level of household chaos when compared to mothers of autistic adolescents, and mothers of adolescents with both ADHD and autism (Schiltz et. al., 2022). Research has also shown that when parents are able to see their child’s ADHD as a “biological disability” it helps to transform their feelings towards their child and their child’s behaviours, allowing them to have more empathy and compassion (Ringer et. al., 2020). Specifically, rather than seeing the child’s behaviour simply as unwillingness to do what was being asked, they could see that their child was struggling to meet expectations. An important part of the work I do is helping parents understand the full impact of an ADHD diagnosis for their child.

Unfortunately, ADHD continues to be seen as a condition characterized by poorly behaved children rather than a neurodevelopmental condition impacting cognitive functions that influence a large variety of abilities and behaviours. Somehow, we continue to leave too much of the burden on the ADHD child rather than acknowledge the continued misunderstanding of ADHD, the deficiencies in the educational system, and the insufficient resources to support ADHD children and adolescents. I am first to tell my ADHD clients that their ADHD brain wiring can bring them huge strengths – these kids are unique, energetic, creative firecrackers. But too many of these brilliant children and adolescents feel like their ADHD is nothing but a curse because they don’t meet neurotypical standards. I have yet to meet an ADHD child or adolescent who doesn’t want to do well. Our job is to make it possible. And one of the most important steps is not allowing ADHD to continue to be disrespected as the serious neurodevelopmental condition that it is.

According to a new study on the Family Burden of Raising a Child with ADHD the cost of raising a youth with ADHD was more than five times greater compared to raising a youth without ADHD. The total economic burden per child with ADHD was $15,036 US compared to $2,848 per neurotypical child on average. This cost difference remained even after additional disorders such as intellectual impairment, oppositional defiant disorder symptoms, and conduct problems. Costs for medication and the direct treatment for ADHD were not included in these costs.

These additional costs were due:

These findings will not be surprising for families of children or grown children with ADHD, but having hard data could be very helpful in our Disability Tax Credit advocacy efforts.

CADDAC and CADDRA are currently in communication with the federal government about CRA’s handling of Disability Tax Credit applications. In a recent letter to Senator Jim Munson and Diane Lebouthillier, the Minister of National Revenue, CADDRA stated that a recent survey of ADHD medical professionals reported that they had experienced an increase in requests for additional information even when that information was present in the original application. This has resulted in the filling out these forms becoming an onerous task taking away time spent more appropriately on patient care. CADDRA members also indicated that they felt that CRA was not respecting their expertise as qualified health care practitioners. Also in this joint letter, CADDAC reported that a recent survey of individuals with ADHD and their families found that 63% of patients with ADHD were denied the DTC even when their physicians found them markedly impaired in keeping with the DTC criteria.

The letter went on to say that while CADDRA and CADDAC appreciated the work done in recent reports, the Senate Standing Committee on Social Affairs, Science and Technology: “Breaking Down Barriers, a critical analysis of the Disability Tax Credit and the Registered Disability Savings Plan” and the “Disability Tax Credit: Medical Practitioners’ Report”, October 2018, both these reports lacked vital input from neurodevelopmental organizations such as CADDRA and CADDAC. Both organizations offered our expertise both in general and with respect to disability assistance to the government.

Note from Heidi Bernhardt, CADDAC President

I am sharing this incident with you because the CADDAC board and I personally continue to be concerned about how information on ADHD is sometimes presented in the media. Unfortunately, poor, even if well-meaning, studies and their questionable findings are being reported, using by-lines meant to be eye catching and memorable. I understand that a reporter may feel that they are only regurgitating what a researcher puts out there, but when they report on an ADHD study that they are not qualified to evaluate and do not reach out to those who are, misinformation on ADHD just keeps increasing. And using headlines and personal stories to sensationalize and misinform just makes it worse. This harms families who are already stigmatized by all the misunderstanding and myths that continue to abound about ADHD. CADDAC and CADDRA are sometimes contacted by journalists seeking out ADHD experts to evaluate and comment on a new study prior to reporting on it. This is how it should be done.

I would be very interested in hearing your comments on this topic. You can send your comments to me at

 Huffington Post Article

On December the 7th the Huffington Post published an article titled, Mom's Postpartum Depression Linked To ADHD In Kids, Australian Study Finds ‘Parenting hostility' is connected to a child's eventual diagnosis or symptoms”. This was first brought to my attention on December the 8th when I was copied on a letter sent to the Huffington Post by a psychologist and contacted by a second psychologist concerned about the messages in this article.

In her complaint to the Huffington Post the psychologist stated that the by-line was,

incredibly damaging to parents who are parenting children with “invisible disabilities,” especially ADHD, which has already been so heavily stigmatized in the media.”

She went on to add that the byline

“… makes the results appear causal, when they are not, but it is also entirely misleading. Only several paragraphs in do you finally get to the critical point made by the researchers: “We suspect that children's challenging behaviour early in life may be connected to mother's postnatal mental health." Why not lead with that critical information? Why not avoid contributing to the vast amount of misinformation and misunderstanding that is already making it so painful for families of children with this neurodevelopmental disability?”

Although the article was edited and the title and by-line changed to “Study On Postpartum Depression And ADHD Stresses Need For Maternal Health Support, Moms shouldn't blame themselves, researchers say” by the Huffington Post within hours after receiving the complaint, I and others remain concerned about this article. The article you now see on the Huffington post if not the original article.

Here is a comment by a parent that was sent to the Huffington Post that I was copied on.

“I see that there are some areas of the article which state that mothers should not be made to feel blamed for their child's ADHD, and that a child's ADHD may contribute to depression in the parent. However, the title of the article, certain statements within it, and the direct quotes from Melissa Doody, paint an entirely different picture. These imply that depression in the mother CAN indeed cause ADHD in a child. Anyone who skims through your headlines or through this article will come away with that message…I feel sorry for Melissa Doody, since she clearly believes that she is responsible for her child's ADHD, when she is absolutely not. Spreading her self-deprecating statements around is not helpful, and is simply irresponsible.”

When I personally contacted the author of the article it was suggested to me that there was no problem with the reporting but that rather I and the psychologist who complained simply did not like the information the study highlighted. To test this theory I reached out to some other medical professionals to get their impression of this article. Several pointed out that they had significant concerns about this article and the messages it was sending. One physician stated that articles like this made her blood boil. Several mentioned the fact that fathers had been completely left out of the equation and that this was another case of blaming the mother for the child’s problems.

I consider this another version of the ‘Blame the mother syndromes’ that were taught to me in med school.  I could argue quite passionately that the dysregulated infant who will later in childhood be diagnosed with ADHD is in fact the cause of the mother's postnatal depression.”


“However, this also brings me to my other major concern with both the article and the study itself: it is hideously gendered, and contributes to further mother-blaming in the world of mental health. There is no mention of fathers at all, and yet "parenting" is the term used, where what they're really looking at is ‘mothering.’"

Upon examining the actual study professionals commented that,

“…critical confounding variables are unaccounted for (i.e. most notably, the genetic links between ADHD, anxiety, and mood disorders), are all weak, at best.”


“Also important is to note that they did not control for cigarette or alcohol use during pregnancy or pre or perinatal birth complications when exploring the association between maternal post natal mental health and offspring symptoms of ADHD.”

A few other issues with the study were noted; children were not necessarily diagnosed with ADHD but rather reported to have ADHD by their parents; depression was not evaluated as to whether it was an on-going depression or a postpartum depression; mothers were not screened for ADHD.

I received other comments questioning the validity of this study’s finding and expect to receive more in the future, but since I am still receiving correspondence on this article from concerned parents and professionals I felt that it was important to comment on it sooner rather than later.

If necessary, I will write a follow-up on the actual study itself once it has been further analyzed.

Again, please feel free to let me know what you feel about this issue at

New research just published in the Journal of the American Medical Association is questioning whether heavy use of media platforms over time can increase the presentation of ADHD symptoms in adolescents. The study looked at the use of 14 different digital media activities using platforms such as social media, texting and streaming media in a large number of adolescents, 2587, in grades 10 to 12. According to their responses they were divided into three categories, no use, medium use and high use. Adolescents with pre-existing ADHD symptoms were intentionally excluded from the study.

The study’s findings reported that among adolescents followed up over 2 years, there was a statistically significant but modest association between higher frequency of digital media use and subsequent symptoms of ADHD. The results indicated that those with low use of digital media over the two-year period, about 500 adolescents, had the fewest number of symptoms, 4.6%. Those with highest use of digital media showed the highest rate of ADHD symptoms, between 9.5% and 10.5%. The researchers cautioned that the study's findings did not prove cause and effect; more research would be needed to do so.  However, they were confident in saying that higher levels of digital media use did increase the likelihood of ADHD symptom presentation in the future.

Expert Reaction to the study

This past weekend an important opinion piece, written by several prominent BC ADHD experts was published in “The Province”, a daily newspaper published in BC.

The piece entitled, “Opinion: ADHD is a real brain disorder requiring treatment, despite what some say” opens with a request that BC medical colleagues demand that the Therapeutics Initiative, which is government funded in the amount of 10 million dollars, be de-funded again. The opinion piece goes on to state that the report, or therapeutics letter,  created by unnamed experts, most likely none of which are paediatricians or psychiatrists, cherry-picked research and grossly misrepresented ADHD evidence to support their ill-intentioned claims and prejudices. The ADHD experts equates the Therapeutic Initiative’s report, which questions the safety and validity of ADHD treatment, to a psychiatric version of the vaccination debate.

The comment piece outlines the abundance of current ADHD research and the impact of untreated ADHD and states that, “The increased use of ADHD medication in BC is heartening because it suggests that more children are being diagnosed and treated. However, with only four per cent of B.C. children receiving treatment, ADHD is still under-diagnosed and often goes untreated.” While the piece points out that medication is not required by everyone with ADHD, it also states that large review studies have shown and continue to show the benefits of treating ADHD with medication. Furthermore, these medications have been prescribed for more than 80 years.

It is extremely disheartening for those of us who work in the field of ADHD and for those who themselves have ADHD or family members affected by this disorder to be required to continually justify the diagnosis and treatment of a medical disorder that has been proven to be significant and real. What is even more worrisome is that the type of report published by the Therapeutics Initiative, which according to the ADHD experts would never have been published in a legitimate medical journal, was put out by the media only furthering the misinformation on ADHD.

The only way to stop this type of misinformation from continuing to be spread by the media with a goal of sensationalism is for those of us in the field and those impacted by ADHD to speak up.

Therefore, CADDAC sincerely congratulates and thanks these physicians, Drs. Diane McIntosh, BSc Pharmacy, MD, FRCPC, psychiatrist and clinical assistant professor, UBC; Derryck Smith, MD, FRCPC, psychiatrist and professor emeritus, UBC; Don Duncan, MD, FRCPC, psychiatrist and clinical assistant professor, UBC, clinical director, B.C. Interior ADHD Clinic; Dorothy Reddy, BSc, MD, FRCPC, research fellow, psychiatrist; Julia Hunter, BSc, MSc, MD, FRCPC, psychiatrist, for speaking out.

CADDAC strongly encourages families and adults impacted by ADHD to send a letter to the editor of any publication that furthers the spread of misinformation about ADHD, even when it is an opinion piece.  The test that I use when reviewing an article on ADHD is to question whether the same bias and questioning about the validity of the disorder would occur if the mental disorder being discussed was depression.

I just found out about a brand new area of research on ADHD that I find fascinating. For many years I have wondered why those, including family members, with ADHD express extreme reluctance and sometimes downright refusal to tackle certain tasks that others find simple.

I was alerted about a recent study looking at Differences in Perceived Mental  Effort Required and Discomfort during a Working Memory Task between Individuals At-risk And Not  by one of our members who was confused by the term “at-risk for ADHD”.  So, I decided to go directly to the source and contacted Maggie Toplak, one of the researchers, who I happen to know. Dr. Toplak shared my questions with her co-researcher on this study, Dr. John Eastwood.

Here is the information that was provided by Dr. Eastwood.

What does the term “at-risk for ADHD” mean?

We used the Adult ADHD Self Report Scale (ASRS), which is a symptom checklist based on DSM diagnostic criteria. It is used as a screening tool to identify who would likely meet criteria for ADHD. However, it is not a full, formal assessment. Thus, we labelled those who were identified on this screen as likely having ADHD as being "at risk".

What is this study looking at?

There is little work on ADHD and the experience of mental effort. Most models assume that those with ADHD avoid effortful tasks because they either have diminished capacity to complete effortful tasks and/or because they lack motivation to complete effortful tasks.

What are the findings to-date?

Our work is hinting - much more still needs to be done - at the possibility that individuals with ADHD experience effortful tasks as being more distressing and uncomfortable than those without ADHD. Sort of like a strong negative emotional response...even in situations where they are doing as well as those without ADHD. The idea is that the same situation is experienced differently. So it may be less about cognitive ability and motivation and more about emotion. The same mental task gives rise to different emotions for those with and without ADHD. If so, this means we need interventions that focus on reducing the emotional reaction to effortful tasks rather than simply interventions that work on increasing executive functioning skills (to improve ability on tasks and ability to self-regulate motivation).

In recent years, biomedical research has identified many "drug-response genes.”  These are genes that wield a substantial impact on how people react to medications.

Several companies are making consumer-level tests available, with ADHD medications as well as with medications for depression and more. These purport to identify the kind of drug-response genes the consumer might have. For now, these tests require a physician’s prescription. That does not mean, however, that every physician ordering these tests know how to correctly interpret the results.

The point of this blog series: to help mental healthcare consumers understand how these test results might prove useful—and how the results are extremely limited.

Though far from perfect, these tests can now provide valuable insights into what drugs, at what dosage, might be best for treating your or your loved one’s ADHD— and which drugs might pose complications.

Points to note:

  1. The test is not diagnostic for ADHD
  2. The test does not indicate that anyone (ADHD or not) taking the test will achieve good therapeutic results from the medications in the “try these first” columns, in the sense that these medications will mitigate ADHD symptoms. For that, we look to the published literature examining the effectiveness of these medications. And we also consider individual response.
  3. Similarly, the test does not indicate that anyone with ADHD will not gain benefit from the medications in the “try these last” or “caution” category. It is extremely important to understand: The decision to rule out a medication should not be based on these tests.  Even if a drug poses complications, it does not mean the medication will not be the best choice for that individual.
  4. Our perspective is that these tests are perhaps most useful when it comes to indicating if an individual will metabolize a medication very quickly—or very slowly. This can inform the starting dosage and indicate if, even with the longer-acting medications, the person might need a much higher than average dose or perhaps even multiple daily doses.

ADHD Gene Testing Series: A Recap

Part 1  provides an overview to the topic of genetic testing as it relates to ADHD medication-response.

Part 2 shares testing results for my husband (who has ADHD) and me (who does not), along with my husband’s personal reactions to our disparate genes.

Part 3 defines what is meant by the term genotyping test. Briefly, it’s a test that informs you of your genetic particulars. Specifically for our purposes in this blog series, it refers to tests that identify which variants of the drug-response genes known to be associated with ADHD medications that you have.

Part 4 explains how, when, and why this data might prove helpful, delving more deeply into the topics of pharmacokinetics (what your body does to the medication) and pharmacodynamics (what the medication does to the body).

Part 5 reminds that genotyping data provides only one piece of the puzzle. There are many other factors that can affect how well a medication works for you, including overall health factors and co-existing conditions.

Adult ADHD-Focused Couple Therapy: Clinical Interventions


Since 2010 CADDAC has shared our concerns about the direct substitution of methylphenidate ER-C, a generic medication, for OROS® methylphenidate (Concerta) with Health Canada. This was done through documentation, caregiver and patient survey results and several face to face meetings.

A Canadian research paper reviewing data on this issue, was recently published in the Clinical Therapeutics Journal on drug therapy. The new paper, “Differences in Adverse Event Reporting Rates of Therapeutic Failure Between Two Once-daily Extended-release Methylphenidate Medications in Canada: Analysis of Spontaneous Adverse Event Reporting Databases” looked at treatment failure adverse events of generic versions of OROS® methylphenidate (Concerta).

The research paper reported that a 10-fold higher reporting rate of therapeutic failure adverse events was found with the Canadian generic product, methylphenidate ER-C (Teva product) as compared to OROS® methylphenidate (Concerta).  Although adverse events are more typically thought of as additional unwanted effects of a drug (e.g. a headache or rash), if a product fails to produce its expected intended clinical effect, or fails to produce its clinical effect for the intended duration, there may be an adverse outcome for the patient, including an exacerbation of the condition for which the product is being used.  The Health Canada Guidance on Reporting Adverse Reactions to Marketed Health Products provides the example of a patient whose condition is well-stabilized, but deteriorates when the patient changes to a different brand or receives a new prescription as an example of an unusual failure in efficacy, which is a reportable adverse event.

Additionally, the study compared Canada-US data and demonstrated that this 10-fold increase in Canadian therapeutic adverse events was very similar to data seen with a US generic product by Mallinckrodt. This US product's bioequivalence status has been removed by the FDA and it is being considered for further regulatory action. Adverse consequences for patients, such as disruptions in academic performance, school suspensions, and onset of adverse social behaviors, showed similarities between the US and Canadian generics. The Canadian study data reported that “Impacts on social functioning, such as disruption in work or school performance or adverse social behaviors, were found in 22.2% of cases.” US reports for the methylphenidate ER generic product identified adverse impacts on social functioning in more than 30% of cases.

The paper also highlighted differences in the generic medication from the brand Concerta Plasma (blood) concentrations. The generic product concentrations peaked approximately 2 hours earlier and declined more rapidly than those of Concerta. As one would expect, adverse event time of day data, showed “overdose like” symptoms to be more common in the morning and lack of efficacy to be more common in the afternoon. Methylphenidate ER-C,  was reported not to be effective throughout the duration of the day in 42.6% of Canadian cases, with this early loss of efficacy occurring in the afternoon for 64.3%.  Signs or symptoms of too much methylphenidate exposure were also reported in 13.5% of the cases with 58.1% occurring in the morning. Therapeutic failure occurred within one week of starting treatment with methylphenidate ER-C in 72.1% of the cases.

CADDAC’s experience was included as well, “Since the market approval of the first generic drug in Canada, the Centre for ADHD Awareness Canada (CADDAC), a patient advocacy group, has received reports of issues with generic methylphenidate ER medications, including shortened or reduced clinical effects and adverse events.”

The paper concluded that “The results of the current study are consistent with a growing literature pointing to a potential safety issue with the methylphenidate ER-C generic product. Taken together, this information suggests that an investigation should be conducted by Health Canada, to evaluate the potential differences between methylphenidate ER-C and OROS® methylphenidate. If important differences are identified, this would further suggest that the bioequivalence metrics currently used to support the interchangeability of OROS® methylphenidate with methylphenidate ER-C may not be adequate.”

Earlier this year Health Canada (HC) released a notice regarding consultation on the proposed modification to bioequivalence standards for this type of medication. In September, CADDAC contacted HC expressing our pleasure with this review, but asked whether any decisions made would also impact medications that had already been approved for bioequivalency. This is information is important because the medication for ADHD in question would fall under this category.  If this was not to be the case, CADDAC wanted to know whether labeling informing patients that this medication was approved under old guidelines would be required. CADDAC has yet to hear back from Health Canada.

While researching this topic I came across several articles listing a variety of Apps that can be useful for those with ADHD. Not surprisingly, many of these APPS are simple reminders, or assist with time management and organization. Some are designed for children, such as Epic Win which turns boring chores into a fun role playing adventure, or 123Token which rewards positive behaviours with a token system.

An APP named Rescue Time builds reports on how you spend your time. This allows you to track time spent procrastinating as compared to time spent on productive activities. Another APP, Freedom, allows you to set the time(s) that your internet is turned off, allowing you to restrict distractions at the end of day or for particular periods during the day. We all know that e-mails and social media etc. can be hugely distracting if not limited. Others are designed to help build healthy habits, manage your money and restrict impulsive spending.

A note of caution; be leery of Apps that claim to improve executive functioning and decrease ADHD symptoms. To date there are no peer reviewed, large scale studies that back up these claims.
