According to a study published in the New York Times, new figures reveal one in 10 children are diagnosed with Attention Deficit Hyperactivity Disorder.
That represents 11 percent of school-aged children in the US.
Historically, ADHD has been estimated to affect 3-7 percent of children.
The overall figures are a 16 percent rise since 2007 and a 53 percent increase over the past decade, according to the study.
However, some experts say that many children who get diagnosed may not actually have the condition.
The report also found that about two-thirds of children take prescriptions such as Adderall or Ritalin. While these drugs can improve the lives of patients, they may also result in addiction, anxiety and even psychosis.
