In a study of over 1600 middle school children in Connecticut, those who consumed heavily sweetened energy drinks were 66 percent more likely to experience hyperactivity and inattention. The children were also consuming too much sugar and other studies of energy drinks in children show increased caffeine intake. One more encouragement to be aware of your child's sugar intake - and decrease it!

In children with a specific gene mutation, small amounts of lead may contribute to symptoms of ADHD, especially hyperactivity and impulsivity. Children can be exposed to small amounts of lead through water that passes through aging pipes, as well as contaminated soil and dust. Some toys and costume jewelry may also contain lead, so parents may want to check the following website: www.healthytoys.org
