Tourette's syndrome and ADHD

People with Tourette's syndrome often have other problems as well, the most common of which is attention-deficit hyperactivity disorder (ADHD). Researchers at the universities of Calgary and Toronto studied 400 children with Tourette's some of whom had ADHD and some of whom did not. They found that children with low birth weights, who had been born prematurely and whose mothers had smoked during their pregnancy were two-or-three times more likely to have ADHD, replicating results in the general population.
