Why Does Every Statement About ADHD on This Blog Have a Scientific Source? On the Power of Peer Review and Accountability

Suppose you read a few articles on this blog. In that case, you will quickly notice something distinctive: the abundance of references to scientific publications, citations of studies, and specific figures with confidence intervals. To some readers, this may seem excessive. Do we really need all these citations? Can’t we write about ADHD more casually, without all the academic baggage? The answer is no, if we care about the truth and the safety of our readers.

What is Peer Review and Why is it Important?

When a scientist conducts research and wants to publish the results, it is not enough to write an article and send it to a journal. Every serious scientific publication undergoes peer review, i.e., review by experts. This means that several independent scientists in the field, often world-class specialists, read the manuscript, check the methodology, verify the statistics, look for errors in reasoning, and ask about alternative explanations for the results. Only after their approval and the introduction of any corrections can the article be published.

This process is not perfect—errors sometimes slip through the review, and overly cautious reviewers sometimes reject good work. However, it is still the best mechanism we have for separating confirmed knowledge from speculation. When I discuss a study from Nature Genetics or the Journal of Attention Disorders, I know it has undergone rigorous verification. When someone writes a blog without sources or cites “research” from popular science websites, I have no guarantee that the information is accurate.

Example: The myth of “ADHD as a Diet Effect”

Let’s see how this difference works in practice. It is commonly claimed that ADHD is mainly the result of the modern diet – too much sugar, too little omega-3, artificial colors, and preservatives. It sounds convincing and gives hope that ADHD can be “cured” by changing one’s diet. However, when we turn to peer-reviewed literature, the picture becomes more complicated.

Yes, studies are showing that omega-3 supplementation can slightly improve some symptoms of ADHD, especially in children with a documented deficiency of these acids. However, the effect is modest: we are talking about a 10-15% improvement on symptom assessment scales, not a “cure.” At the same time, we have hundreds of studies showing a substantial genetic contribution, and the heritability of ADHD is estimated at 75% in meta-analyses of twin studies. This means that genes explain much more of the variance in ADHD symptoms than dietary factors do.

If this blog were not based on reliable sources, I could write an enthusiastic article about the “miracle ADHD diet,” giving false hope to parents and delaying real help for children. Instead, by citing specific studies, I can tell the truth: diet can be part of the support, but it cannot replace professional diagnosis and treatment. It’s less impressive, but it’s honest.

Transparency and Verifiability

Every quote, every reference to a study that you find on this blog has a specific purpose—it allows you to verify my interpretation. If I write that the ABCD study showed a 9% variance in ADHD symptoms explained by the additive “gene plus environment” model, I provide a link to the publication. You can go there, read the abstract, see the data tables, and check whether my interpretation is honest or whether I am skewing the results in any direction.

This transparency is the foundation of trust. You don’t have to take my word for it. You can check it out. And if you find that I’ve misinterpreted something, let me know. Science is a process of continuous error correction, and no author, even the most conscientious, is infallible. But this process only works if it is verifiable.

Updating Knowledge

Another advantage of relying on peer-reviewed literature is the ability to track the progress of knowledge. Our understanding of ADHD is not static. Every year, hundreds of new studies are published that deepen, modify, or sometimes challenge previous findings. In 2015, geneticists did not yet know a single genome-wide significant locus for ADHD. In 2019, twelve were discovered. By 2023, there were already twenty-seven confirmed loci and dozens of suspected ones.

By following high-quality publications, I can update the blog content as discoveries emerge. I can inform readers that specific previous theories have been modified in light of new data. I can remain current and reliable in a rapidly evolving field. If I relied on popular articles or my own intuition, the blog would become frozen in time, presenting outdated knowledge as truth.

Ethics of Responsibility

Finally, I want to address the issue of ethics. When writing about mental health, especially a disorder that affects millions of people, I bear a huge responsibility. People come here looking for help, often in difficult life situations, struggling with symptoms that affect their work, relationships, and self-esteem. I cannot take their trust lightly.

My commitment to citing peer-reviewed sources is my way of honoring that trust. It is an acknowledgment that I do not have a monopoly on the truth, but I can point the way to the most reliable knowledge available at the moment. It is a recognition that the reader deserves not my opinion, but the best available evidence.

If you are looking for a blog about ADHD based on solid scientific foundations, where you can verify every claim, where your intelligence and right to check the facts are respected, then you are in the right place. And if you have doubts about a source or interpretation, ask. Dialogue based on reliability is the best path to the truth.
