ADHD in Russia: checking figures and sources
Why foreign prevalence estimates cannot automatically be applied to Russia, and why an online questionnaire does not diagnose ADHD.
A Sinqly editorial review. Updated September 27, 2026. Sources are listed below; research findings are distinguished from editorial suggestions.
What matters about adult ADHD
NIMH describes ADHD as persistent difficulties with attention and/or hyperactivity and impulsivity that interfere with functioning in different areas of life. Assessment considers a history going back to childhood and other possible explanations for difficulties. A single measure of inattention does not establish a diagnosis.
Where percentages come from
The NIMH statistics page describes studies of the US population and specifies age groups and research methods. These results cannot be labeled as prevalence in Russia or worldwide. We have no verifiable representative Russian study here that establishes an exact number of adults with ADHD or a proportion of people without a diagnosis.
Why checking the source matters
When reading statistics, look for the primary publication, country, participant ages, collection year and how ADHD was identified. Diagnostic interviews and self-report questionnaires have different limitations. This review provides no medical recommendations and does not assess the reader's probability of having ADHD.
Practical observation steps
- Save the original link, not just a number from a summary.
- Prepare examples of difficulties in different situations for a discussion with a professional.
- Do not infer the presence or absence of ADHD from a Sinqly questionnaire result.
Sources and limits of the findings
This review is not new research. The cited studies do not test Sinqly’s effectiveness. For personal notes, you can use paper or a habit tracker; choosing a tool does not by itself guarantee a result.
