Image: Left, the brains of adults who had ADHD as children but no longer have it show synchronous activity between the posterior cingulate cortex (the larger red region) and the medial prefrontal cortex (smaller red region). Right, the brains of adults who continue to experience ADHD do not show this synchronous activity (Photo courtesy of Jose-Luis Olivares/MIT - based on images courtesy of the researchers).

fMRI Brain Scans Reveal Differences in Adults Who Have Recovered from Childhood ADHD and Those Who Did Not

In a study to compare patterns of brain activity in adults who recovered from childhood with attention deficit hyperactivity disorder and those who did not, neuroscientists have discovered key differences in a brain communication network that is active when the brain is at wakeful rest and not focused on a particular task.   More...
