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.

Counting umbilical cord vessels is standard in prenatal ultrasounds and confirmed at birth. Single umbilical artery (SUA) occurs in about 1 in 200 cases, with roughly 10% associated with anomalies, including central nervous system defects. Isolated SUA (iSUA) means one artery is missing without other structural issues.
Research on SUA, especially isolated iSUA, and childhood neurodevelopmental disorders (NDD) is limited and inconclusive. iSUA is linked to preterm birth and small-for-gestational age (SGA), both of which are NDD risk factors.
This Norwegian nationwide population study aimed to assess NDD risk in children with iSUA at birth, the influence of sex, and how preterm birth and SGA mediate this relationship.
The nation’s universal single-payer health insurance and comprehensive population registries made it possible to analyze all 858,397 single births occurring from 1999 to 2013, with follow-up continuing through 2019. Among these cases, 3,532 involved iSUA.
After adjusting for confounders such as parental age, education, and maternal health factors, no overall link was found between iSUA and later ADHD diagnosis. However, females with iSUA had about a 40% higher risk of subsequent ADHD compared to those without iSUA, even after adjustment.
The authors concluded, “The present study indicates that iSUA is weakly associated with ID [intellectual disability] and ADHD, and these associations are influenced by sex. This association is mediated negligibly through preterm birth and SGA. The associations were not clinically significant, and the absence of associations of iSUA with other NDD is reassuring. This finding can be useful in the counseling of expectant parents of fetuses diagnosed with iSUA.”
Refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (distorted vision due to irregular curvature of the eye or lens), are common worldwide. These conditions affect 12%, 5%, and 15% of children, and rise significantly in adults to 26.5%, 31%, and 40%. Additionally, strabismus (misalignment of the eyes) and amblyopia (reduced vision in one eye from uneven image formation, often linked to strabismus) occur globally at rates of 2% and 1.4%, respectively.
Visual impairment can affect children’s concentration in school, and studies suggest a link between eye disorders and ADHD.
To investigate this relationship, two researchers – one based in the US and the other in Israel –carried out a nationwide retrospective cohort study using electronic medical records of all insured individuals aged 5 to 30 who were part of Maccabi Health Services, Israel’s second largest health maintenance organization, between 2010 and 2022.
Of over 1.6 million insured members (2010–2020), inclusion/exclusion criteria and propensity score matching for age and sex were applied, along with a one-year wash-out period between the first eye diagnosis and ADHD diagnosis. In total, 221,707 cases were matched with controls without eye disorders at a 1:2 ratio, resulting in a cohort of 665,121 participants.
Overall, those with any previous eye diagnosis were 40% more likely to have a subsequent ADHD diagnosis. This was slightly higher for females (45%) than for males (35%). It was also slightly higher for children and adolescents (42%) than for adults (37%).
More specifically:
The authors concluded that eye disorders are associated with ADHD. They noted these associations were more marked in females and children and adolescents, although, as noted above, those differences were small. They recommended that primary care providers and neurologists consider risk stratification for early screening, and that ophthalmologists refer high-risk patients for ADHD evaluation.
Acid-suppressive medications, including proton pump inhibitors (PPIs) and histamine-2 (H2) receptor antagonists, are often prescribed during pregnancy to treat heartburn and gastroesophageal reflux disease.
Research shows changes in the gut microbiome can negatively affect neurodevelopment. Since acid-suppressive medications alter gut microbiota, maternal use during pregnancy may impact offspring’s neurodevelopment. Because PPIs and H2 receptor antagonists readily cross the placental barrier, they could potentially influence fetal neurodevelopment.
The link between prenatal exposure to acid-suppressive medications and major neuropsychiatric disorders is not well understood. With the use of these medications during pregnancy rising, it is important to assess their impact on children's long-term neurodevelopment. This study examined whether maternal use of acid-suppressive drugs is associated with increased risk of neuropsychiatric disorders in children, using a large, nationwide birth cohort from South Korea.
South Korea operates a single-payer health insurance system, providing coverage for over 97% of its citizens. The National Health Insurance Service (NHIS) maintains a comprehensive database with sociodemographic details, medical diagnoses, procedures, prescriptions, health examinations, and vital statistics for all insured individuals.
A Korean research team analyzed data from over three million mother-child pairs (2010–2017) to assess the risks of prenatal exposure to acid-suppressing medications. They applied propensity scoring to adjust for maternal age, number of children, medical history, and outpatient visits before pregnancy, to minimize confounding factors. That narrowed the cohort to just over 800,000 pairs, with half in the exposed group.
With these adjustments, prenatal exposure to acid-suppressing medications was associated with 14% greater likelihood of being subsequently diagnosed with ADHD.
Yet, when 151,737 exposed births were compared to the same number of sibling controls, no association was found between prenatal exposure and subsequent ADHD, which suggests unaccounted familial and genetic factors influenced the preceding results.
The Take-Away:
Evidence of these medications negatively affecting pregnancies is mixed, mostly observational, and generally reassuring when these medications are used appropriately. Untreated GERD and gastritis, however, have known risks and associations with the development of various cancers. With no evidence of an association with ADHD (or for that matter any other neuropsychiatric disorder), there is no current evidence-based reason for expectant mothers to discontinue use of acid-suppressing medications.
