What can Doctors do about Fake ADHD?

ADHD is a serious disorder that requires treatment to prevent many adverse outcomes. But, because the diagnosis of ADHD is based on how the patient responds to questions, people can pretend that they have ADHD when they do not. If you Google "fake ADHD" you'll get many pages of links, including a Psychology Today article on the topic and bloggers describing how they were able to fool doctors into giving them ADHD medications. Is fake ADHD a serious problem? Not really. The Internetseems to be faking an epidemic of fake ADHD.I say that because we have decades of research that show many objective measures of abnormality and impairment in people who say they have ADHD. These include traffic accidents, abnormalities in brain imaging, and molecular genetic differences. Some studies even suggest that ADHD adults downplay their ADHD symptoms. For example, one study diagnosed ADHD in children and then contacted them many years later when they were young adults.When they were interviewed as young adults, their responses to questions about ADHD suggested that they did not have the disorder. But when the same questions about the patient were asked to someone who lived with the patient as a young adult, it was clear that they still had ADHD. So rather than faking ADHD, many ADHD adults do not recognize that they have symptoms of the disorder. That said, we also know from research studies that, when asked to pretend that they have ADHD, adults can fake the disorder. That means that they can learn about the symptoms of the disorder and makeup examples of how they have had them when they have not. The research discussed above suggests that this is not common, but we do know that some people have motives for faking ADHD.For example, some college students seek special accommodations for taking tests; others may want stimulants for abuse, misuse, or diversion. Fortunately, doctors can detect fake ADHD in several ways. If an adult itself-referred for ADHD and asks specifically for stimulant medication, that raises the possibility of fake ADHD and drug-seeking. Because the issue of stimulant misuse has been mostly a concern on college campuses, many doctors treating college students will require independent verification of the patient's ADHD symptoms by speaking with a parent, even over the phone if an in-person visit is not possible. Using ADHD rating scales will not detect fake ADHD, and it is easy to fake poor performance on tests of reading or math ability. Neuropsychological tests can sometimes be used to detect malingering, but require referral to a specialist. Researchers are developing methods to detect faking ADHD symptoms. These have shown some utility in studies of young adults, but are not ready for clinical practice. So, currently, doctors concerned about fake ADHD should look for objective indicators of impairment (e.g., documented traffic accidents; academic performance below expectation) and speak to a parent of the patient to document that impairing symptoms of the disorder were present before the age of twelve. Because the issue of fake ADHD is of most concern on college campuses, it can also be helpful to speak with a teacher who has had frequent contact with the patient. In an era of large lecture halls and broadcast lectures, that may be difficult. And don't be fooled by the Internet. We don't want to deny treatment to ADHD patients out of undocumented reports of an epidemic of fake ADHD.

Meta-analysis of Two Nationwide Population Studies Finds No Harm to Offspring from Taking ADHD Medications During Pregnancy

ADHD is the most prevalent neurodevelopmental disorder. Nearly 1% of pregnant women in the Nordic countries and more than 1% in the United States are prescribed ADHD medications, ranking these among the most commonly used medications during pregnancy. However, the safety of exposing a fetus to ADHD medications is still uncertain, prompting many expectant mothers to stop using them out of fear for their unborn child’s well-being. 

The Study:

A European research team conducted a comprehensive nationwide study on the safety of ADHD medications during pregnancy using populations from Sweden and Denmark. The Swedish population was studied first, followed by inclusion of a separate study of the Danish population. Results were then combined through meta-analysis. Nordic countries, with their single-payer national health insurance systems and national population registers, facilitate the tracking of residents’ health from birth to death, thus providing robust data for such studies. 

The team accounted for various potential confounders, including maternal age, year of delivery, whether the mother was a first-time parent, self-reported smoking during pregnancy, and any psychiatric history. They also considered psychiatric inpatient or outpatient treatment received within two years before pregnancy, as well as the dispensing of other psychotropic medications during pregnancy, including antidepressants, antipsychotics, antiseizure medications, and anti-anxiety medications. Additionally, they examined the highest level of maternal education and civil status at delivery (married or cohabiting compared to single, divorced, or widowed). 

Out of 861,650 Swedish children, 2,257 were exposed to ADHD medications during pregnancy. Another 3,917 were born to mothers who discontinued ADHD medications before pregnancy.  

Children exposed to ADHD medications had lower rates of ADHD, autism spectrum disorder, and overall neurodevelopmental disorders; however, none of these differences were significant. 

Limiting the analysis to siblings to control for family environmental influences and genetics likewise found no significant differences.  

A meta-analysis combining the Swedish results with a separately conducted nationwide population study in neighboring Denmark similarly found no significant differences between children exposed to ADHD medications during pregnancy and children born to mothers who discontinued ADHD medications before pregnancy. 

Conclusion:

The team concluded, “Overall, our study provides reassuring evidence that continuing ADHD medication during pregnancy does not increase the risk of long-term NDDs [neurodevelopmental disorders] in offspring." 

From Meds to Mindfulness: What Actually Works for Adult ADHD?

A new large-scale study has shed light on which treatments for attention-deficit/hyperactivity disorder (ADHD) in adults are most effective and best tolerated. 

Researchers analyzed 113 randomized controlled trials involving nearly 15,000 adults diagnosed with ADHD. These studies included medications (like stimulants and atomoxetine), psychological therapies (such as cognitive behavioral therapy), and newer approaches like neurostimulation.

The Findings

Stimulant medications (lisdexamfetamine and methylphenidate) as well as selective norepinephrine reuptake inhibitors (SNRI) (atomoxetine) were the only treatments that consistently reduced core ADHD symptoms—both from the perspective of patients and clinicians. It may be worth noting that atomoxetine, while effective, was less well tolerated, with more people dropping out due to side effects.

Psychological therapies such as CBT, mindfulness, and psychoeducation showed some benefits, but mainly according to clinician ratings—not necessarily from the patients themselves. Neurostimulation techniques like transcranial direct current stimulation also showed some improvements, but only in limited contexts and with small sample sizes. Interestingly, none of the treatments—medication or otherwise—made a clear impact on long-term quality of life or emotional regulation. 

Conclusion 

So, what does this mean for people navigating ADHD in adulthood? Stimulant medications remain the most effective treatment for managing ADHD symptoms day-to-day but nonstimulant medication are not far behind, which is good given the problems we’ve had with stimulant shortages. This study also supports structured psychotherapy as a viable treatment option, especially when used in conjunction with medication. 

The study emphasizes the importance of ongoing, long-term research and the need for treatment plans that are tailored to the individual ADHD patient– Managing adult ADHD effectively calls for flexible, patient-centered care.

Taiwan Nationwide Population Study Finds Link Between ADHD and Early Puberty, Also Protective Effect of Methylphenidate

Precocious puberty (PP) is defined as the onset of secondary sex characteristics before age 8 in girls or age 9 in boys.  

Because it accelerates skeletal maturation by prematurely shutting down the cartilage growth plate at the tip of long bones, it tends to lead to shorter height in adulthood. It is also known to place an additional psychological burden on children, especially girls. Girls are four to 38 times more likely to develop PP than boys. 

Taiwan has a single-payer national health insurance system, called National Health Insurance, that encompasses 99.6% of the island’s population. The Ministry of Health and Welfare uses it to maintain the National Health Insurance Research Database (NHIRD), enabling researchers to conduct nationwide population studies. 

Using this database, a Taiwanese study team investigated the relationship between ADHD and precocious puberty among children and adolescents (under 18). And because methylphenidate (MPH) is the only psychostimulant approved for the treatment of ADHD in Taiwan, the team also explored the effect of MPH on this relationship. 

Most diagnoses of ADHD in the NHIRD are made by board-certified psychiatrists, enhancing diagnostic validity. 

Of the more than 3.3 million persons born in Taiwan between 1997 and 2001, 186,681 were diagnosed with ADHD. Of these, 122,302 were prescribed MPH. 

After adjusting for sex, low-income households, and neuropsychiatric comorbidities, children diagnosed with ADHD were twice as likely to be diagnosed with PP. This held equally true for boys and girls. 

However, children diagnosed with ADHD and prescribed MPH were more than a third less likely to subsequently be diagnosed with PP than those diagnosed with ADHD but not prescribed MPH.  

For girls with ADHD, who without an MPH prescription were nine times more likely than boys with ADHD to be diagnosed with PP, an MPH prescription reduced that ratio to five times more likely than boys with ADHD and prescribed MPH. 

That suggests a strong protective effect of MPH.  

The team concluded, “Our study found that children with ADHD were at a greater risk of PP, and girls with ADHD were a particularly vulnerable group. … MPH appeared to be protective against PP in patients with ADHD, especially in girls. However, these preliminary results need further validation.”
