Attention deficit hyperactivity disorder

The Wikipedia article on Attention deficit hyperactivity disorder has been edited 14,190 times since it was created in 2002, by 4,394 distinct accounts and IP addresses. That averages about 587 recorded changes a year, or several every day, which puts it among the more actively maintained pages on the encyclopedia.

Within the revisions retrieved for this report, the ten busiest contributors account for about 46% of the changes, with the rest spread across a long tail of occasional editors. That is a fairly typical mix of regular maintainers and passing corrections. In the same window, about 11% of the retrieved revisions came from bot accounts, which handle routine work such as link repair and reference formatting.

Within the retrieved window, 2025 carries the most recorded activity, with 269 changes. 21 of those revisions fall in the last 90 days. The most recent recorded edit was 28 days ago.

Readership has been broadly stable across the last two years of pageview data. The clearest peak in that record falls in October 2024. Traffic spikes and editing spikes often line up, but the revision record alone cannot tell you which one caused the other, or whether an outside event drove both.

This report is built from the 500 most recent revisions retrieved from Wikipedia, about 4% of the 14,190 recorded edits. Figures drawn from that window describe the window only, and the report cannot establish why a change was made or whether it was correct.
