Are you comfortable?
Lying still for a brain scan isn't easy for eleven-year-old Micah Diggs. He has attention deficit hyperactivity disorder, or ADHD, and is usually in constant motion.
Really, really active, anxious most of the time, always seems to wanna go onto something else, you know?
But Micah's brave efforts have paid off. His brain scans have helped provide a major clue into understanding ADHD. Researchers found that the frontal lobes in brains of kids with the disorder are smaller in volume than the brains of kids without it. Doctor Stewart Mostofsky made the breakthrough discovery at Kennedy Krieger institute in Baltimore.
What we found was that it didn't seem like there was one particular region that was abnormal within the frontal lobe. Rather we saw abnormalities in a few different regions.
The frontal lobe is a third of the brain. It's considered the emotional control center involved in motor function, spontaneity, and impulse control.
What causes these abnormalities is a very important question and it may be genetics, it may be environment and quite possibly, ya know, a combination thereof.
For now doctor Mostofsky will focus on how the brain abnormalities contribute to ADHD.
What is different about the brain structure and function that contributes to the constellations, uh, symptoms that we see in the disorder?
Thanks to Micah's family and others like them, doctors are one step closer to an improved diagnosis and better treatments for ADHD.
It just seems to bring a little bit of comfort there, ya know, when they discover something new.
