A new 2026 JAMA Psychiatry brain imaging study found that ADHD may not be one single brain pattern. Researchers identified three ADHD biotypes linked to different brain-network patterns, including emotional dysregulation, hyperactive/impulsive symptoms, and inattentive symptoms.

In this video, I break down what the study actually found, why this does not mean ADHD now has three official new diagnoses, and why it may help explain something many of us already know: one-size-fits-all ADHD advice often fails.

We’ll talk about:

The 3 ADHD biotypes identified in the study

Why emotional dysregulation may be a major part of ADHD for some people

How hyperactive/impulsive ADHD may involve the brain’s “brake system”

Why inattentive ADHD can be quiet, internal, and easy to miss

Why planners, routines, and productivity hacks don’t work the same for everyone

What this research could mean for future ADHD treatment personalization

This is not medical advice, and you cannot diagnose your ADHD subtype from a YouTube video. But this research may help us better understand why ADHD looks so different from person to person — and why the right support has to match the actual struggle.

If you’ve ever felt like ADHD advice didn’t fit your brain, this one is worth watching.
