ADHD is a neurobehavioral disorder that is typically diagnosed during childhood. Although many people (children in particular) display the predominant characteristics of this disorder – inattentiveness, hyperactivity, and/or impulsivity – individuals with ADHD have more severe and recurrent symptoms that impair their daily lives. Recently, there has been lot of controversy <http://www.healthcentral.com/adhd/c/1443/150680/controversy-diagnosis?ic=2602> over how and when ADHD should be diagnosed.
Based on IMS Health data and discussion at the Food and Drug Administration (FDA) Pediatric Advisory Committee in September 2012, it has been noted that there is off-label use of Vyvanse® (lisdexamfetamine dimesylate) in children under 5 years old (4%, or approximately 100,000 patients between February 2007 and March 2012). The lack of controlled data regarding the safety and efficacy of Vyvanse® in the preschool ADHD population, in concert with the prevalence of off-label prescribing of Vyvanse® supports the need for Vyvanse® studies in the preschool ADHD population. Importantly, it is not known if the therapeutic effects of stimulant medications in school age children with ADHD can be extrapolated to preschool children with ADHD.

Inattentiveness signs and symptoms of ADD/ADHD
It isn’t that children with ADD/ADHD can’t pay attention: when they’re doing things they enjoy or hearing about topics in which they’re interested, they have no trouble focusing and staying on task. But when the task is repetitive or boring, they quickly tune out.
Staying on track is another common problem. Children with ADD/ADHD often bounce from task to task without completing any of them, or skip necessary steps in procedures. Organizing their schoolwork and their time is harder for them than it is for most children.
Kids with ADD/ADHD also have trouble concentrating if there are things going on around them; they usually need a calm, quiet environment in order to stay focused.
Symptoms of inattention in children:
Hyperactivity signs and symptoms of ADD/ADHD
The most obvious sign of ADD/ADHD is hyperactivity. While many children are naturally quite active, kids with hyperactive symptoms of attention deficit disorder are always moving. They may try to do several things at once, bouncing around from one activity to the next. Even when forced to sit still which can be very difficult for them their foot is tapping, their leg is shaking, or their fingers are drumming.
Symptoms of inattention in children:
Impulsive signs and symptoms of ADD/ADHD
The impulsivity of children with ADD/ADHD can cause problems with self-control. Because they censor themselves less than other kids do, they’ll interrupt conversations, invade other people’s space, ask irrelevant questions in class, make tactless observations, and ask overly personal questions.
Instructions like “Be patient” and “Just wait a little while" are twice as hard for children with ADD/ADHD to follow as they are for other youngsters. Children with impulsive signs and symptoms of ADD/ADHD also tend to be moody and to overreact emotionally. As a result, others may start to view the child as disrespectful, weird, or needy.
