In a November 12, 2007 BBC report, researchers reported that drugs taken for Attention Deficit / Hyperactivity Disorder (ADHD) are not only ineffective over the long term, they may deliver a negative effect on normal childhood growth.
The long-term study, called the Multimodal Treatment Study of Children with ADHD, closely monitored 600 children across the United States.
Comprehensive data showed that while ADHD drugs may help a child behave better in the short run, the effect of the drugs will wear off over time. In addition, ADHD drugs are now being found to stunt a child’s height and weight.
ADHD is one of the most common neurobehavioral disorders of childhood and can persist through adolescence and into adulthood. A person with ADHD has a chronic level of inattention, impulsive hyperactivity, or both.. Scientists do not know what causes this disorder.
