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.

Background
ADHD (Attention-Deficit/Hyperactivity Disorder) is one of the most studied neurodevelopmental conditions, with many clinical trials evaluating the effectiveness and safety of various medications. These trials, known as randomized controlled trials (RCTs), are considered the gold standard for assessing treatments. However, strict eligibility criteria often exclude many real-world patients, raising questions about whether the findings from these trials apply to everyday clinical settings.
Our latest study sheds light on this issue, revealing just how many individuals with ADHD might be excluded from RCTs and the impact this exclusion has on their treatment outcomes.
Method
Researchers used Swedish national registries to analyze data from 189,699 individuals diagnosed with ADHD who started medication between 2007 and 2019. They applied exclusion criteria from 164 international RCTs to identify who would have been considered ineligible for these trials in order to determine the proportion of individuals with ADHD who would not meet the eligibility criteria for RCTs.
Key Findings
Many Patients Are Ineligible for Clinical Trials:
Ineligible Patients Face Unique Challenges:
Higher Risk of Adverse Outcomes:
What This Means
These findings highlight a major gap between the controlled environments of clinical trials and the realities faced by individuals with ADHD in everyday life. While RCTs provide valuable insights, their restrictive criteria often exclude patients with more complex health profiles or co-existing conditions. This limits the generalisability of trial results, meaning that treatment guidelines based solely on RCTs may not fully address the needs of all patients.
Conclusion
This study demonstrated that a significant proportion of individuals with ADHD, particularly adults, do not meet the eligibility criteria for standard RCTs. These results emphasize the importance of bridging the gap between research settings and real-world applications. By recognizing and addressing the limitations of RCTs, we can work towards more equitable and effective ADHD treatment strategies for everyone.
Background:
Our understanding of Attention-deficit/hyperactivity disorder (ADHD) has grown and evolved considerably since it first appeared in the DSM-II as “Hyperkinetic Reaction of Childhood.” This study aimed to find the disorder’s placement within the modern psychopathology classification systems like the Hierarchical Taxonomy Of Psychopathology (HiTOP).
The HiTOP model aims to address limitations of traditional classification systems for mental illness, such as the DSM-5 and ICD-10, by organizing psychopathology according to evidence from research on observable patterns of mental health problems.. Is ADHD best categorized under externalizing conditions, neurodevelopmental disorders, or something else entirely? A recent study by Zheyue Peng, Kasey Stanton, Beatriz Dominguez-Alvarez, and Ashley L. Watts takes a closer look at this question using a symptom-focused approach.
The Study:
Traditionally, ADHD has been associated with externalizing behaviors, such as impulsivity and hyperactivity, or with neurodevelopmental traits, like cognitive delays. However, this study challenges the idea of placing ADHD into a single category. Instead, it maps ADHD symptoms across three major psychopathology spectra: externalizing, neurodevelopmental, and internalizing.
The findings reveal that ADHD symptoms don’t fit neatly into one box. For example, symptoms like impulsivity, poor school performance, and low perseverance were strongly associated with externalizing behaviors. On the other hand, cognitive disengagement (e.g., daydreaming, blank staring) and immaturity were closely linked to neurodevelopmental challenges. Interestingly, cognitive disengagement also showed ties to internalizing symptoms, such as anxiety or depression.
This research underscores the complexity of ADHD. Rather than treating ADHD as a single, unitary construct, the study advocates for a symptom-based approach to better understand and treat individuals. By acknowledging that ADHD symptoms relate to multiple psychopathology spectra, clinicians and researchers can move toward more nuanced classification systems and targeted interventions.
Conclusion:
Ultimately, this study highlights the need for modern systems to move beyond rigid categories and adopt a more flexible, symptom-focused framework for understanding ADHD’s place in psychopathology.
Exposure to heavy metals like lead, arsenic, mercury, cadmium, and manganese is known to harm developing nervous systems. However, past studies on whether heavy metals specifically increase the risk of ADHD have shown mixed results.
A research team from China (Gu et al., 2024) reviewed medical studies and conducted meta-analyses to better understand this issue.
The team included studies on children and teens, focusing on cohort studies, case-control studies, and cross-sectional studies. They only used articles written in English and required validated biomonitoring (like blood tests) to measure heavy metal exposure. ADHD diagnoses had to come from clinical evaluations.
To be included, studies had to report effect sizes such as odds ratios and relative risks with confidence intervals. The team focused on comparisons between groups with high, low, or no exposure, which made it harder to analyze dose-response relationships.
They also evaluated the quality of each study. All cohort studies were rated high-quality. Of the 15 case-control studies, 6 were high-quality, and 9 were moderate-quality. Among cross-sectional studies, only 2 were high-quality, and the rest were moderate-quality.
There was no evidence linking ADHD to other heavy metals like arsenic, mercury, cadmium, or manganese. Both meta-analyses suggest that lead exposure is associated with the risk for ADHD. However, because these studies cannot rule out other explanations, one cannot conclude that lead exposure causes ADHD. For example, other work shows that people with ADHD are likely to have lower incomes than those without ADHD.
