Neurodevelopmental disorders, such as autism and attention-deficit/hyperactivity disorder (ADHD), affect how a child’s brain develops. It’s made up of billions of neurons—tiny brain cells that help us move, think, and feel. Golgi neurons help brain cells talk to each other. When these cells don’t develop the right way, it might raise the chances of having disorders like autism or ADHD. As scientists keep studying this link, they may discover new treatments to help children with developmental challenges live better lives.
