Natural Remedies for ADHD: Are they Effective?

Stephen V. Faraone, PhD on September 2, 2021

Are Nonpharmacologic Treatments for ADHD Useful?

There are several very effective ADHD medications, and treatment guidelines from professional organizations view these drugs as the first line of treatment for people with ADHD symptoms.  (The only exception is for preschool children where medication is only the first line treatment for severe ADHD; the guidelines recommend that other preschoolers with ADHD be treated with non-pharmacologic treatments, when available.)

Despite these guidelines, some parents and patients have been persuaded by the media or the Internet that ADHD drugs are dangerous and that non-drug alternatives are as good or even better. Parents and patients may also be influenced by media reports that doctors overprescribe ADHD drugs or that these drugs have serious side effects. Such reports typically simplify and/or exaggerate results from the scientific literature.  Thus, many patients and parents of ADHD children are seeking “natural remedies for ADHD.” 

What are these non-pharmacologic treatments and do they work?  

My upcoming series of blogs will discuss each of these treatments in detail.  Here I’ll give an overview of my evidenced-based taxonomy of nonpharmacologic treatments for ADHD described in more detail in a book I recently edited (Faraone, S. V. & Antshel, K. M. (2014). “ADHD: Non-Pharmacologic Interventions.” Child Adolesc Psychiatr Clin N Am 23, xiii-xiv.).  I use the term “evidenced-based” in the strict sense applied by the Oxford Center for Evidenced Based Medicine (OCEBM; http://www.cebm.net/). 

Most of the non-drug treatments for ADHD fall into three categories: behavioral, dietary, and neurocognitive.

Behavioral interventions include training parents to optimize methods of reward and punishment for their ADHD child, teaching ADHD children social skills and helping teachers apply principles of behavior management in their classrooms.  Cognitive behavior therapy (CBT) is a method that teaches behavioral and cognitive skills to adolescent and adult ADHD patients.

Dietary interventions include special diets that exclude food colorings or eliminate foods believed to cause ADHD symptoms.  Other dietary interventions provide supplements such as iron, zinc or omega-3 fatty acids.

Neurocognitive interventions typically use a computer based learning setup to teach ADHD patients cognitive skills that will help reduce ADHD symptoms.

There are two metrics to consider when thinking about the evidence-base for these methods.  The first is the quality of the evidence.   For example, a study of 10 patients with no control group would be a low quality study, but a study of 100 patients randomized to either a treatment or control group would be of high quality, and the quality would be even higher if the people rating patient outcomes did not know who was in each group. 

The second metric is the magnitude of the treatment effect.  Does the treatment dramatically reduce ADHD symptoms or does it have only a small effect?  This metric is only available for high quality studies that compare people treated with the method and people treated with a ‘control’ method that is not expected to affect ADHD.

I used a statistical metric to quantify the magnitude of effect. Zero means no effect and larger numbers indicate better effects on treating ADHD symptoms.  For comparison, the effect of is about 0.9, which is derived from a very strong evidence base.     The effects of dietary treatments on symptoms of adult ADHD are smaller, about 0.4 to 0.5, but because the quality of the evidence is not strong, these results are not certain and the studies of food color exclusions apply primarily to children who have high intakes of such colorants.

In contrast to the dietary studies, the evidence base for behavioral treatments is excellent but the effects of these treatments of ADHD symptoms is very small, less than 0.1.    Supplementation with omega-3 fatty acids also has a strong evidence base but the magnitude of effect is also small (0.1 to 0.2).    The neurocognitive treatments have modest effects on ADHD symptoms (0.2 to 0.4) but their evidence base is weak.

This review of non-drug treatments explains why ADHD drug treatments are usually used first.  Their evidence base is stronger and they are more effective in reducing ADHD symptoms.  There is, however, a role for some non-drug treatments. I’ll be discussing that in subsequent blog posts.

ADHD Coaching an Integral Component of Effective Comprehensive Treatment for Adults with ADHD

David Giwerc, MCAC, MCC on July 14, 2016

Research clearly indicates psychopharmacology’s prominent role as an ADHD intervention.

Even if the primary care physician is comfortable with treating an ADHD adult, the typical office visit does not allow sufficient time to address every issue that confronts the newly diagnosed adult ADHD patient. The patient may leave with an appropriate ADHD medication regimen, but many other critical problems related to the diagnosis may remain unaddressed.

Medications can significantly improve focus while reducing other symptoms of ADHD. However, ADHD medications alone cannot teach the patient how to compensate for life skills that were never learned due to the years of executive function impairment.

ADHD coaching builds a bridge between biology and behavior and narrows the gap between ability and performance. Patients and physicians are beginning to realize the importance of including an ADHD coach as part of the treatment team. Just as an athletic coach motivates an athlete, ADHD coaches are very adept at motivating their clients who have ADHD, while partnering with them to develop and practice newly learned personal, social, and professional skills. For some patients, these skills may not have been developed due to lack of ADHD education, proper diagnosis, and treatment.

The stigma surrounding ADHD as nothing more than an “unruly child syndrome,” coupled with the popularity of incorrectly self-diagnosing an ADHD impairment, means too many patients are conditioned not to speak up and not to seek support, especially in the workplace. Adult ADHD coaching clients have often stated that an ADHD coach was the first person to not only understand the frustration of their invisible challenges, but also to sincerely believe all of their ADHD stories.

Physicians can rarely provide the level of attention and encouragement an adult patient needs within the restrictions of the typical office visit. The coach, therefore, can reinforce their patients’ natural talents and successes. The PAAC* or ICF**-certified ADHD coach can create an environment that encourages open communication (necessary for behavioral changes to occur) and forms a foundation of unconditional acceptance. Coupled with science-based instruction about ADHD, the coach focuses on identifying the patient’s natural talents and successes and develops a plan to convert that into daily strengths.

ADHD coaches help the client develop coping strategies, a valuable adjunct to medication management. They are highly specialized professionals, well-versed in ADHD-specific coaching competencies. The coach provides psycho-educational support, improves self-awareness of how symptoms of ADHD, and helps translate that into improved short and long-term performance.

While coaching cannot replace stimulant medications or therapy as a treatment, a coach can provide customized strategies and education that work alongside medication. The ADHD coach may suggest lifestyle changes such as proper sleep, nutrition, physical activity, and breathing exercises. In addition, ADHD coaching is accessible, with most coaching being conducted via phone/Skype, eliminating the need for geographical proximity or disruption to the work day.

ADHD and Suicide

Stephen V. Faraone, PhD on March 17, 2016

Suicide is one of the most feared outcomes of any psychiatric condition.  Although its association with depression is well known, a small but growing research literature shows that ADHD is also a risk factor for suicidality.  

Suicide is difficult to study. Because it is relatively rare, large samples of patients are needed to make definitive statements.  Studies of suicide and ADHD must also consider the possibility that medications might elevate that risk. 

For example, the FDA placed a black box warning on atomoxetine because that ADHD medication had been shown to increase suicidal risk in youth.   A recent study of 37,936 patients with ADHD now provides much insight into these issues (Chen, Q., Sjolander, A., Runeson, B., D’Onofrio, B. M., Lichtenstein, P. & Larsson, H. (2014). Drug treatment for attention-deficit/hyperactivity disorder and suicidal behaviour: register based study. BMJ 348, g3769.).    In Sweden, such large studies are possible because researchers have computerized medical registers that describe the disorders and treatments of all people in Sweden.  Among 37,936 patients with ADHD, 7019 suicide attempts or completed suicides occurred during 150,721 person years of follow-up.  This indicates that, in any given year, the risk for a suicidal event is about 5%. 

For ADHD patients, the risk for a suicide event is about 30% greater than for non-ADHD patients.  Among the ADHD patients who attempted or completed suicide, the risk was increased for those who had also been diagnosed with a mood disorder, conduct disorder, substance abuse or borderline personality.  This is not surprising; the most serious and complicated cases of ADHD are those that have the greatest risk for suicidal events.  

The effects of medication were less clear.   The risk for suicide events was greater for ADHD patients who had been treated with non-stimulant medication compared with those who had not been treated with non-stimulant medication.  A similar comparison showed no effect of stimulant medications. 

This first analysis suffers from the fact that the probability of receiving medication increases with the severity of the disorder.  To address this problem, the researchers limited the analyses to ADHD patients who had had some medication treatment and then compared suicidal risk between periods of medication treatment and periods of no medication treatment.  This analysis found no increased risk for suicide from non-stimulant medications and, more importantly, found that for patients treated with stimulants, the risk for suicide was lower when they were taking stimulant medications.  This protective effect of stimulant medication provides further evidence of the long-term effects of stimulant medications which have also been shown to lower the risks for traffic accidents, criminality, smoking and other substance use disorders.

ADHD and Hyperactivity – Children, Teens, Adults

Anthony L. Rostain, MD MA on January 21, 2016

This article reviews existing evidence for the use of locomotor activity measures in diagnosing ADHD. The authors conducted a meta-analysis of published studies on ADHD using motion measures to compare patients with ADHD with controls and then conducted a case control study using the McLean motion activity test (MMAT) on a sample of child, adolescent and adult ADHD patients (N=81) and matched controls (N=91).

 

Methods

The meta-analysis procedure involved searching several electronic medical databases and selecting only articles which used validated methods for diagnosing ADHD, which compared ADHD subjects to healthy controls and which reported data in ways that enabled the authors to calculate the effect sizes as measured by standardized mean differences (SMD) between study groups. A total of 18 studies were chosen, 13 of which involved actigraphy measures and 5 which used motion tracking systems. The combined sample sizes were 570 ADHD patients (305 children and adolescents and 265 ADHD adults) and 515 controls (equally divided between youth and adults). The SMD (or effect size) between ADHD subjects and controls was 0.64 using actigraphy measures and 0.92 using the motion tracking systems. The SMD or pooled effect size for youth was 0.75 and for adults was 0.73, indicating that excessive motion is seen as often in adult ADHD patients as in children and adolescents. This contradicts the prevailing view that excessive motor activity is less prominent in adults as compared to youth with ADHD.

 

The authors then conducted a case control study comparing ADHD patients and controls. Patients were diagnosed using a comprehensive assessment procedure consisting of structured psychiatric interviews, Conners’ rating scales and the BRIEF (a measure of executive functioning). Subjects were administered the MMAT, an infrared motion tracking system that measures the micro-movements of participants during a Go/No-Go task (15 minutes for youth and 20 minutes for adults). ADHD groups differed significantly from controls on most motion measures, with an effect size of 0.83 for adults and 0.45 for children and adolescents. Reaction time variability was also significantly greater in the ADHD sample across all ages (p<0.05). Interestingly, there were no differences in excessive motion seen among the different ADHD subtypes (combined vs inattentive vs hyperactive vs NOS).

 

Ask the ADHD Experts – Prescribing Medications

 

Conclusions

The authors conclude that locomotor hyperactivity is a core constituent feature of ADHD even in adults and across all diagnostic subtypes. They further suggest that objective locomotion measures may be useful in improving the process of diagnosing difficult cases of ADHD. While it is still premature to suggest that movement measurement devices like the MMAT are necessary for ADHD diagnosis in most patients, there is certainly a role for using them in clinical practice along with established ADHD resources. Future research will help delineate additional uses for these tools in diagnosing other neurodevelopmental disorders.

ADHD and Insomnia

Stephen V. Faraone, PhD on December 10, 2015

ADHD itself is associated with sleep difficulties, independent of ADHD medications. Thus, it is very important that sleep quality is assessed prior to treatment so that the changes due to treatment can be correctly inferred.


(Editor’s Note: See our Ask the ADHD Experts session on ADHD and Sleep.)


In clinical trials of stimulant ADHD medications, insomnia is typically noted a side effect of the medications. But most of these studies have used subjective patient or parent reports of sleep quality. A new meta analysis, reviews 9 studies of a total of 246 patients enrolled in randomized controlled trials of a stimulant medication.


Ask_the_ADHD_Experts_-_Prescribing_MedicationsTo be included, studies must have had an objective measure of sleep quality, either polysomnography or actigraphy. The analysis showed that stimulant medications led to a) a longer time to get to sleep; b) worse sleep efficiency and c) a shorter duration of sleep. Some of these sleep measures worsened with an increasing number of doses and a shorter time on medication.


Given the adverse effects that lack of sleep can have on cognition and behavior, these data provide further impetus for clinicians, parents and patients to monitor the effects of stimulant ADHD medication on sleep and to take appropriate action (e.g., dose reduction, change of medication) as warranted.

ADHD: Facts or Fiction

Stephen V. Faraone, PhD on July 2, 2015

Many ADHD myths have been manufactured over the years.  Facts that are clear and compelling to most scientists and doctors have been distorted or discarded from popular media discussions of the disorder.   Sometimes, the popular media seems motivated by the maxim “Never let the facts get in the way of a good story.”  That’s fine for storytellers, but it is not acceptable for serious and useful discussions about ADHD.

ADHD Myths are easy to find.  These myths have confused patients and parents and undermined the ability  of professionals to appropriately treat the disorder.   When patients or parents get the idea that the diagnosis of ADHD is a subjective invention of doctors, or that ADHD medications cause drug abuse, that makes it less likely they will seek treatment and will increase their chances of having adverse outcomes.


Fortunately, as John Adams famously said of the Boston Massacre, “Facts are stubborn things.”  And science is a stubborn enterprise; it does not tolerate shoddy research or opinions not supported by fact.   ADHD scientists have addressed many of the myths about the disorder in the International Consensus Statement on ADHD, a published summary of scientific facts about ADHD endorsed by a of 75 international ADHD scientists in 2002.  The statement describes evidence for the validity of ADHD, the existence of genetic and neurobiologic causes for the disorder and the range and severity of impairments caused by the disorder.


Download The Consensus Statement


The Statement makes several key points:


The U.S. Surgeon General, the American Medical Association, the American Psychiatric Association, the American Academy of Child and Adolescent Psychiatry, the American Psychological Association, and the American Academy of Pediatrics recognize ADHD as a valid disorder.

ADHD involves a serious deficiency in a set of psychological abilities and that these deficiencies pose serious harm to most individuals possessing the disorder.

Many studies show that the psychological deficits in people with ADHD are associated with abnormalities in several specific brain regions.

The genetic contribution to ADHD is routinely found to be among the highest for any psychiatric disorders.

ADHD is not a benign disorder. For those it afflicts, it can cause devastating problems.

Hundreds of studies have shown the effectiveness of ADHD medications and multiple therapies.

The facts about ADHD will prevail if you take the time to learn about them.   This can be difficult when faced with a media blitz of information and misinformation about the disorder.  In future blogs, I’ll separate the ADHD facts from the fiction by addressing several popular myths about ADHD.

Natural Remedies for ADHD: Are they Effective?

ADHD, Biofeedback, and Cognitive Training

Stephen V. Faraone, PhD on April 2, 0215

It sounds like science fiction, but scientists have been testing computerized methods to train the brains of ADHD people with the goal of reducing both ADHD symptoms and cognitive deficits such as difficulties with memory or attention.   Two main approaches have been used: cognitive training and neurofeedback.  This of course is in addition to, not a replacement for, ADHD medications.

 

Cognitive training methods ask patients to practice tasks aimed at teaching specific skills such as retaining information in memory or inhibiting impulsive responses.  Currently, results from ADHD brain studies suggests that the ADHD brain is not very different from the non-ADHD brain, but that ADHD leads to small differences in the structure, organization and functioning of the brain.  CBT_rubricThe idea behind cognitive training is that the brain can be reorganized to accomplish tasks through a structured learning process.  Cognitive retraining helps people who have suffered brain damage, so was logical to think it might help the types of brain differences seen in ADHD people.  Several software packages have been created  to deliver cognitive training sessions to ADHD people.  You can read more about these methods here: Sonuga-Barke, E., D. Brandeis, et al. (2014). “Computer-based cognitive training for ADHD: a review of current evidence.” Child Adolesc Psychiatr Clin N Am 23(4): 807-824.

 

Neurofeedback was applied to ADHD after it had been observed, in many studies, that people with ADHD have unusual brain waves as measured by the electroencephalogram (EEG).We believe that these unusual brain waves are caused by the different way that the ADHD brain processes information. 

 

Because these differences lead to problems with memory, attention, inhibiting responses and other areas of cognition and behavior, it was believed that normalizing the brain waves might reduce ADHD symptoms.  In a neurofeedback session, patients sit with a computer that reads their brain waves via wires connected to their head.  The patient is asked to do a task on the computer that is known to produce a specific type of brain wave.   The computer gives feedback via sound or a visual on the computer screen that tells the patient how ‘normal’ their brain waves are.  By modifying their behavior, patients learn to change their brain waves.  The method is called neurofeedback because it gives patients direct feedback about how their brains are processing information.

 

Both cognitive training and neurofeedback have been extensively studied.  If you’ve been reading my blogs about ADHD, you know that I play by the rules of evidenced based medicine.  My view is that the only way to be sure that a treatment ‘works’ is to see what researchers have published in scientific journals.   The highest level of evidence is a meta-analysis of randomized controlled clinical trials.   For my lay readers, that means that many rigorous studies have been conducted and summarized with a sophisticated mathematical method.   Although both cognitive training and neurofeedback are rational methods based on good science, meta-analyses suggest that they are not helpful for reducing ADHD symptoms.  They may be helpful for specific problems such as problems with memory, but more work is needed to be certain if that is true.

 

The future may bring better news about these methods if they are modified and become more effective.  You can learn more about non-pharmacologic treatments for ADHD from a book I recently edited: Faraone, S. V. & Antshel, K. M. (2014). ADHD: Non-Pharmacologic Interventions. Child Adolesc Psychiatr Clin N Am 23, xiii-xiv.

 

As a reminder, adult ADHD tests can be administered easily and effectively to measure the effect of various approaches on ADHD symptoms in adults.
