In our digital age, the internet serves as a powerful platform for accessing health information. Yet, with this great power comes great responsibility. Misinformation, particularly concerning ADHD (Attention-Deficit/Hyperactivity Disorder), is rife online, leading to confusion, the perpetuation of stigma, and potentially harmful consequences for those affected by the disorder and their loved ones. This blog will delve into some of these misconceptions, their impacts, and how to ensure the ADHD information you come across online is reliable, with a special emphasis on a recent study examining ADHD content on TikTok.
The Misinformation Problem
ADHD is a neurodevelopmental disorder that affects both children and adults. It's characterized by patterns of inattention, impulsivity, and hyperactivity that are persistent. Despite its recognition as a well-documented medical condition, it is often misunderstood, partly due to widespread misinformation.
Common ADHD misconceptions include:
ADHD is not a real disorder: This belief is found scattered across online forums, and even some ill-informed news articles.
ADHD is a result of bad parenting: Numerous online discussions blame parents for their child's ADHD. However, research has shown that ADHD has biological origins and is not a result of parenting styles.
ADHD only affects children: Many websites and social media posts promote this myth, but ADHD can continue into adulthood.
ADHD medication leads to substance abuse: Certain posts on social media may wrongly claim that ADHD medication leads to substance abuse.
A recent study explored the quality of ADHD content on TikTok, a popular video-sharing social media platform. Researchers investigated the top 100 most popular ADHD-related videos on the platform. Shockingly, they found that 52% of these videos were classified as misleading, while only 21% were categorized as useful. The majority of these misleading videos were uploaded by non-healthcare providers.
The Impact of Misinformation
Misinformation about ADHD can have harmful impacts on individuals with the disorder and their families:
Delayed diagnosis and treatment: Misinformation can deter individuals and parents from seeking professional help, leading to delays in diagnosis and treatment.
Increased stigma: False information can amplify societal stigma about ADHD, leading to misunderstanding and discrimination.
Harmful treatment approaches: Misinformation can lead individuals to opt for ineffective or even harmful treatments.
The proliferation of misleading ADHD content on platforms like TikTok only amplifies these problems. The TikTok study found that while the videos were generally understandable, they had low actionability — meaning they offered little practical advice for managing ADHD.
Identifying Reliable Information
Given the prevalence of misinformation, it's crucial to be able to distinguish between reliable and unreliable information about ADHD. Here are some pointers:
Use reputable sources: Trustworthy information often comes from recognized health organizations, government health departments, or reputable medical institutions. Some examples are NIH, Mayo Clinic, CDC and www.ADHDevidence.org.
Be wary of fake experts: If you see info from a self-proclaimed expert, you can check to see if they are really an expert by going to www.expertscape.com. Or go to www.pubmed.gov to see if they’ve ever written anything about ADHD that has been approved by their peers.
Look for citations: Reliable sources often cite scientific research to back their claims.
Beware of sensational headlines: Clickbait headlines often oversimplify complex topics like ADHD.
Consult a professional: If you're unsure about any information, consult a healthcare professional.
The TikTok study's findings underscore the importance of these guidelines, as healthcare providers tended to upload higher quality and more useful videos compared to non-healthcare providers.
In our era of digital information, the challenge of separating ADHD facts from fiction is significant but not insurmountable. By becoming discerning consumers of online information, we can help prevent the spread of misinformation, support those affected by ADHD, and foster a more informed and understanding society. It's also essential for clinicians to be aware of the extent of health misinformation online and its potential impact on patient care. This way, they can guide their patients toward reliable sources and away from misleading content.

There has been consistent evidence of an association between ADHD and subjectively reported sleep problems even in patients not medicated for the disorder. There have also been studies using wrist-worn actigraphy (a wrist watch-like device that measures gross motor activity) and sleep lab-based polysomnography that measure objective sleep parameters.
What has been missing are large population-based cohort studies to explore the prevalence rates of different sleep disorders and medical prescriptions in ADHD.
Methods Used:
Sweden has a single-payer health insurance system and a series of national population registers that track virtually its entire population. Using the Swedish Total Population Register, a local research team created a cohort of all 6,470,658 persons born between 1945 and 2008. They linked this to the Swedish National Patient Register, which includes inpatient hospitalizations from 1975 to 2013, and outpatient specialist diagnoses from 2001 to 2013, to identify diagnoses of sleep disorders. They also linked to the Prescribed Drug Register, covering 2005 to 2013, to identify prescriptions for sleep medications.
Summary of Findings:
Overall, persons with ADHD were eight times more likely to be diagnosed with any sleep disorder relative to normally developing peers. Broken down by age, adolescents with ADHD were 16 times more likely to receive such diagnoses, young adults (18-30) twelve times more likely, children and mid-age adults (31-45) eight times more likely, and older adults six times more likely.
Broken down by specific sleep disorder diagnoses, relative to normally developing peers, persons with ADHD were:
As for sleep medication, relative to normally developing peers, persons with ADHD were:
Conclusion:
The team concluded, “Our findings also suggest that greater clinical attention should be directed towards addressing sleep problems in individuals with ADHD. This entails implementing proactive measures through sleep education programmes and providing both pharmacological and non-pharmacological approaches such as cognitive behavioural therapy and parental sleep training.”
Attention is a critical determinant of academic achievement, influencing domains such as language, literacy, and mathematics. To explore whether physical activity can improve attention in children with ADHD, an international team conducted a meta-analysis of peer-reviewed studies. The goal was to evaluate the impact of various physical activity regimens on attention-related outcomes in this population.
The researchers performed a comprehensive search of the medical literature to identify studies examining the effects of physical activity on attention in schoolchildren with ADHD. They included 10 studies with a total of 474 participants in their meta-analysis. The studies evaluated two main types of physical activity:
Additionally, they examined variations based on the frequency, duration, and type of control groups used in the studies. To assess consistency, they also analyzed heterogeneity (variability of outcomes) and checked for potential publication bias.
Key findings from the meta-analysis include:
The authors concluded that mentally engaging exercise is more effective than aerobic exercise in improving attention problems in schoolchildren with ADHD. Furthermore, higher frequency and longer duration of physical activity do not necessarily yield better outcomes.
This research underscores the importance of tailoring physical activity interventions to emphasize cognitive engagement over intensity or duration. By refining strategies, educators and parents can better support children with ADHD in achieving academic success. But take note: given the results from controlled studies, it seems clear that if there is a positive effect of exercise, it is very small so should not replace standard treatments for ADHD.

Previous studies have examined how stimulant medications affect the brain in controlled settings, but less is known about their impact in real-world conditions, where children may not always take their medication consistently or may combine it with other treatments. A new study leverages data from the Adolescent Brain Cognitive Development (ABCD) study to explore how real-world stimulant use impacts brain connectivity and ADHD symptoms over two years.
Changes in Brain Connectivity Researchers used brain imaging data from the ABCD study to examine the functional connectivity—communication between brain areas—of six regions within the striatum, a brain area involved in motivation and movement control. They focused on how stimulant use influenced connectivity between the striatum and other networks involved in executive functioning and visual-motor control.
The study found that stimulant exposure was linked to reduced connectivity between key striatal areas (such as the caudate and putamen) and large brain networks, including the frontoparietal and visual networks. These changes were more pronounced in children taking stimulants compared to those who were not medicated, as well as compared to typically developing children. Importantly, this reduction in connectivity seemed to regulate certain brain networks that are typically altered in children with ADHD.
Symptom Improvement In addition to brain changes, 14% of children taking stimulants experienced a significant reduction in ADHD symptoms over the two-year period. These children showed the strongest connectivity reductions between the right putamen and the visual network, suggesting that stimulant-induced connectivity changes may contribute to improvements in visual attentional control, which is a common challenge for children with ADHD.
Why This Matters This study is one of the first to examine how stimulant use in real-world conditions affects brain networks in children with ADHD over time. The findings suggest that stimulants may help normalize certain connectivity patterns associated with ADHD, particularly in networks related to attention and control. These insights could help clinicians better understand the potential long-term effects of stimulant treatment and guide personalized approaches to ADHD management.
Conclusion Stimulant medications appear to alter striatal-cortical connectivity in children with ADHD, with some changes linked to symptom improvement. This research highlights the potential for stimulant medications to impact brain networks in ways that support attention and control, highlighting the importance of understanding how real-world medication use influences ADHD treatment outcomes.
