How Jessica McCabe turned How to ADHD into a trusted resource
How Jessica McCabe turned How to ADHD from a personal note-keeping hack into one of YouTube's most trusted mental health channels comes down to lived experience plus researcher-reviewed, evidence-based videos. At VidCon 2026, she told Mashable the decade-old project now reaches millions while Dr. Patrick LaCount, her chief science officer, vets every upload.
Ten years ago, McCabe was not trying to become a creator. She was trying not to lose her own research. Notebooks vanished. Phones disappeared. Her mother joked she could lose her own head. When McCabe wanted to revisit articles, studies, or strategies for living with ADHD, she had no system that helped her find or remember anything reliably.
Then she noticed a platform she never misplaced: YouTube. As she told Mashable, anytime she wanted to show someone a funny video, she could find it. Her conclusion was simple: she would not lose YouTube. That insight became How to ADHD, a channel that has since grown into a book, a business, and a fixture in the global mental health conversation.
Key Takeaways
- McCabe launched How to ADHD about a decade ago because YouTube was the one place she could reliably store and retrieve her ADHD research and coping strategies.
- Her research process evolved from solo Google searches to collaboration with ADHD researchers, culminating in chief science officer Dr. Patrick LaCount reviewing every video before publication.
- The channel earned YouTube's Health Shelf trusted-provider badge and now serves roughly 1.94 million YouTube subscribers plus 100,000 TikTok followers.
- McCabe discussed the channel's evolution with Mashable at VidCon 2026, covering team-building, research rigor, and the responsibility of mental health content.
- She hopes more creators will blend personal ADHD experience with evidence-based information rather than sharing tips that worked for only one person.
Why did Jessica McCabe start How to ADHD on YouTube?
The origin story is practical, not performative. McCabe did not set out to become one of YouTube's leading mental health creators. She needed somewhere she would not lose her own notes.
According to Mashable's reporting, she chose the platform because it solved a problem her brain could not. YouTube became an external memory system: a searchable archive for the articles, research, and strategies she was collecting while learning about her own ADHD.
That personal workaround now looks like a textbook case of creator nostalgia meeting real utility. Channels that began as diary projects have often scaled into institutions, and McCabe's journey fits that pattern explored in our Nostalgia: Then & Now coverage. What started as self-help became community infrastructure.
How did McCabe's research process change over the past decade?
Early videos began with basic searches. McCabe would Google questions like what ADD meant and discover terminology and symptoms she had never been taught, including how ADHD affects executive function beyond focus alone.
Commenters pointed her toward Google Scholar and PubMed. Eventually, researchers reached out directly, offering to help her disseminate accurate scientific information. The first collaborator preferred dense academic language; McCabe pushed back because her audience needed plain speech without losing nuance.
Today, Dr. Patrick LaCount serves as the channel's chief science officer and reviews every video before it goes live. That review layer matters at creator speed, when weekly or more frequent uploads make factual errors easy to miss. McCabe told Mashable that if the information is not accurate, the entire project fails its purpose.
What makes How to ADHD a trusted online resource today?
Scale alone does not explain the trust. About ten years in, the channel counts roughly 1.94 million YouTube subscribers and 100,000 TikTok followers. McCabe has published a book titled How to ADHD and is working on a second. The day before her VidCon 2026 interview with Mashable reporter Bethany Allard, she delivered two presentations at the World Confederation of Cognitive Behavioral Therapists Congress alongside doctors and research fellows in psychology and psychiatry.
Viewers also see a Health Shelf badge on the channel, signaling a trusted provider on YouTube's health content shelf. That designation reflects LaCount's pre-publication review process, a safeguard McCabe noted is not standard across mental health YouTube.
Behind the camera, the operation matured from a boyfriend-editor helping with graphics to a full team, including producers, animators, and a community manager hired from the channel's Discord. McCabe has said she now prioritizes soft skills like collaboration and feedback over hard technical skills when hiring.
What did McCabe share at VidCon 2026?
At VidCon 2026, McCabe sat down with Mashable to trace how a personal catalog became a trusted resource for millions of people living with ADHD. She discussed how her research workflow has changed, why researcher partnerships matter, how she built a team around the channel, and what she has learned about balancing authenticity with the weight of publishing mental health content.
She also reflected on audience relationships. Early on, she responded like a peer learning alongside viewers. As the community grew, one-to-one replies became impossible, and she shifted toward making videos that address shared struggles at scale. Motherhood further reshaped her creative focus, pushing the channel toward new formats beyond the original talking-head-on-a-blue-wall style.
Looking ahead, McCabe told Mashable she wants more creators with lived experience to partner with researchers and share evidence-backed information, not just personal anecdotes. Personal stories can open the door, she argued, but the goal is to explain what works for many people, not only what worked once for her.
Then and now: from lost notes to a mental health mainstay?
The through-line is consistency grounded in credibility. McCabe once chased a non-negotiable Tuesday upload schedule while reading every article she could find. Scripts grew longer. Topics multiplied. She eventually stopped researching a brand-new subject every single week, a pace she does not recommend, though it helped produce her book.
What endured is the founding idea: organize thoughts so they cannot disappear. The delivery mechanism changed from a solo creator cold-reading giant-font scripts off a whiteboard to a staffed production with scientific oversight. The mission, however, remains recognizably the same. Help people understand ADHD with information they can trust.
For anyone who remembers when mental health advice online was mostly anecdotal threads, McCabe's arc shows how one creator turned a memory problem into a model other channels may follow. As she put it to Mashable, the best future for this space pairs lived experience with research-backed facts, then puts both where audiences already are: on their screens, ready to replay whenever they need them.
