No, TikTok did not invent ADHD. It has made the subject much louder. Those are two different claims, and confusing them makes it harder to have a useful conversation.

In 1775, Melchior Adam Weikard wrote about a “lack of attention.” In 1798, Alexander Crichton also described difficulties sustaining attention. They were not diagnosing ADHD as we understand it now. Their accounts show that physicians were noticing some of these patterns long before smartphones existed. [1, 2]

That does not mean every historical person who was restless or distractible had ADHD. The modern diagnosis has criteria that eighteenth-century writers did not use. What the old records do give us is a much longer, messier history than the claim that a social platform created the condition.

The language kept changing. In the twentieth century, clinicians wrote about children’s activity, impulse control, attention, and school functioning through different theories. The diagnostic manuals later used “hyperkinetic reaction of childhood,” ADD, and eventually ADHD. Each name reflects what medicine was looking at in that moment. None is a perfect window into every individual’s experience. [2, 3]

I understand why a flood of online ADHD content can make people skeptical. A thirty-second video can start a question; it cannot assess someone. Some posts get things wrong. Some give a person the first words they have ever had for a lifelong difficulty. Both can be true without turning the history into a shouting match.

If you recognize yourself in a Short, use that as a reason to learn more, not as a diagnosis. If you think the whole subject appeared last Tuesday, start with the dates. The full documentary follows the evidence from early descriptions through the changing diagnostic criteria. I made it so you can see where the claims come from.
