New ADHD Findings

Inconsistent short-term memory performance is a strong symptom of Attention-Deficit Hyperactivity Disorder, according to a new study by Dr. Julie Schweitzer of the University of California, Davis. Schweitzer conducted the study while at the University of Maryland.

"Our study helps explain why working memory may be fine at one moment and poor at another, just as one day a child with ADHD seems to be able to learn and focus in class and on another day seems distracted and not paying attention," Schweitzer said in a press release.

In the study, 25 children with ADHD and 25 children without the disorder were asked to perform a number of tasks on a computer. The researchers found that those students with ADHD had considerably less consistent response times, however the study indicates that their rate of correct responses was not any lower.

These findings indicate a measured reason for the seemingly contradictory and erratic focus of those with ADHD.

In a related, though not affiliated study, federal researchers, funded by the National Institute for Mental Health, have reported that the use of drugs to aid children with ADHD is typically only helpful for the first 24 months. The study also found that long-term usage of ADHD drugs may suppress growth in children.

While the study's findings should not be considered definitive, it does continue the heated, two-sided debate of what some consider the over-medication of America's youth. The study also contradicts an earlier study on the same topic.

Approximately 2.5 million American children and teenagers take ADHD medication.
