...kids have no emotional disorders and are simply being used as a baseline to establish the look of a healthy brain. Getting good scans from kids who have diagnosable conditions isn't easy, as any radiologist who has ever tried to conduct a lengthy MRI on a child with ADHD can attest. "Holding still is not exactly what they do well," says Elliott...
Despite such obstacles, research is moving ahead, if haltingly. The National Institute of Mental Health is conducting a study called the Preschool ADHD Treatment Study, in which researchers will track ADHD kids between 3 and 8 years old to determine the benefits and side effects of stimulant medications. Castellanos and N.Y.U. colleague Rachel Klein are taking things further, calling back subjects who were enrolled in an ADHD-treatment study that began in 1970 to scan their now late-30s and early-40s brains for the long-term effects of drugs. Castellanos is also planning a study of young rats treated...
MRIs had already shown that the brain volumes of kids with ADHD are 3% smaller than those of unafflicted kids. That concerned researchers since nearly all those scans had been taken of children already being medicated for the disorder. Were the anatomical differences there to begin with, or were they caused by the drugs? Attempting to answer that, Dr. F. Xavier Castellanos of the New York University Child Studies Center took other scans, this time using only kids with ADHD and comparing those who were taking medication with those who were not. Reassuringly, he discovered that they all shared...
...Steven Pliszka, chief of child psychiatry at the University of Texas Health Center in San Antonio, went further. He conducted scans that picked up not just the structure but the activity of the brains of untreated ADHD children, and compared these images with those from children who had been medicated for a year or more. The treated group showed no signs of any deficits in brain function as measured in blood flow. In fact, he says, "we saw hints of improvement toward normal...
...ADHD for 10 years now. I was diagnosed with it in kindergarten. Truthfully, I don't remember every detail of my life before ADHD, but there are some things I can't help remembering. For example, in kindergarten I was sent to the "time-out chair" about two or three times daily. The reason? I would say things that would hurt the other kids. Why did I say these mean things? Because I'd never think about what I was going to say or the consequences. Another thing I'll never forget is how antsy and talkative I was. Every...
