A Norwegian study of 24 boys (ages 8 to 12) has led researchers to conclude that a single dose of the popular ADHD medication Ritalin can lead to short-term improvements in muscle control and movement among children with a specific type of Attention Deficit Hyperactivity Disorder.

Amy Norton of the Reuters News Service reported on the study in a June 4 article:

The study, reported in the online journal Behavioral and Brain Functions, focused on 24 boys newly diagnosed with hyperkinetic disorder (HKD), a diagnosis nearly identical to attention-deficit hyperactivity disorder-combined type (ADHD-C).

Children with ADHD-C commonly have increased muscle tension, which can hinder normal movement. This, in turn, may manifest as problems such as stiffness, restlessness as a child repeatedly shifts to get comfortable, and even poor handwriting, explained Liv Larsen Stray of the University of Stavanger, the lead researcher on the study.

"Our study shows that a single dose of methylphenidate typically led to improvement of the muscular tone and to a more fluent movement in children with ADHD-C/HKD," Stray told Reuters Health.

Stray's report was first published May 13 on the website of the journal Behavioral and Brain Functions.
