Researchers identified three distinct brain “biotypes” of ADHD, each with its own chemical signature—offering new clues about why treatment can feel like trial and error.

In this Q&A, lead author Dr. Nanfang Pan explains how researchers used structural MRI, normative brain modeling, and machine learning to identify three ADHD biotypes. Each subtype showed distinct ...

For years, stimulant medications for ADHD have been described as chemical accelerators, framed as drugs that rev up a sluggish brain. New imaging work turns that story on its head. Brain scans now ...

Since the same person’s brain doesn’t change in that short window, any differences between scans are from the machines themselves. This template served as a sort of neurotypical control, which allowed ...

ADHD stimulants appear to work less by sharpening focus and more by waking up the brain. Brain scans revealed that these medications activate reward and alertness systems, helping children stay ...

At the same time, several studies have also tried to use brain imaging to better understand ADHD by examining differences in individual brain regions. However, this approach often overlooks how ...

But anyone who works with children with ADHD-or raises one-knows that symptoms can look very different from one child to another. A new brain imaging study now provides scientific evidence for this ...

Over 5% of children and adolescents are diagnosed with attention deficit/hyperactivity disorder (ADHD) globally. This condition is characterized by a short attention span, hyperactivity or impulsive ...

Brain imaging methods like magnetic resonance imaging (MRI) are used to characterize structural differences in the brains of children with attention-deficit ...

Scientists are updating their view of how drugs like Adderall and Ritalin help children with attention deficit hyperactivity disorder stay on task. The latest evidence is a study of thousands of brain ...

A couple of years ago, Jan Haavik was at a routine meeting of a research group that connects scientists studying attention deficit hyperactivity disorder (ADHD) with people who live with the condition ...
