A new study has found that children who can write with both hands are more likely to be hyperactive than kids who can use only one hand in writing. The study, by researchers from Imperial College London, examined 7,871 children from northern Finland, among whom 87 kids could use both hands for writing.
The researchers report that by the time these kids reached the age of seven or eight they developed difficulties with language and performed badly in academics. Furthermore, these kid were more likely to suffer from attention deficit hyperactivity disorder (ADHD) by the time they were 15 years old.

Our results should not be taken to mean that all children who are mixed-handed will have problems at school or develop ADHD. We'd like to stress that most of the mixed-handed children we followed didn't have any of these difficulties."
The details of the study are published in the journal Pediatrics
