Jessica McCabe didn’t start her channel, “How to ADHD,” with the goal of becoming one of YouTube’s leading mental health creators. She started it because she needed somewhere she wouldn’t lose her own notes.
At VidCon 2026, McCabe sat down with Mashable reporter Bethany Allard to discuss how that personal project evolved into a trusted resource for millions of people living with ADHD. She shares how her research process has changed over the years, why she works with researchers to ensure every video is evidence-based, how she built a team around the channel, and what she’s learned about balancing authenticity with the responsibility of creating mental health content.
Watch the full conversation above.
