Causes of ADHD re-examined!
Researchers have reported that for every hour a preschool kid watches television, their risk of developing ADHD (attention deficit hyperactivity disorder) increases by some 10%. Their findings are similiar to previous ones which found that watching too much television can shorten attention span - one of the symptoms of ADHD. However, other scientists argued that although attention span may be affected, it still does not mean that it could be considered a cause of ADHD. One of their main arguments is this: If watching too much television is indeed one of the causes of ADHD, what about those people with ADHD who suffered the disorder way before television was invented?
