Preschoolers and ADHD
Is it possible to diagnose and treat preschoolers with AD/HD? A new study provides much-needed insights.
"Friends didn't want their children to be around our son. I felt like the worst mother in the world." — Mary K.

Mary K., of Hillside, New Jersey, suspected that her son, Brandon, should be diagnosed with attention deficit disorder (ADD ADHD). He was unusually active from the time he was born. "Brandon jumped out of his crib at age one, and hasn't stopped moving, climbing, and jumping since." At first, Mary and her husband ascribed Brandon's high activity level to 'boys being boys'. But when the preschool he attended asked the three-year-old to leave because of concerns about his aggressive and impulsive behaviors, she began to suspect an ADHD diagnosis was needed.
At home, life difficult - as it is for many families with children with ADHD. "Brandon drew on the walls and didn't listen to anything we said. He threw pictures or silverware across the room when he was frustrated, which was all the time. We lived and died by Brandon's moods. If he was in a good mood, everyone in the house was in a good mood, and vice versa. I had a three-year-old running my household," says Mary.
Mary and her husband stopped inviting relatives to their home because they were embarrassed by their lack of control over their preschooler and his ADHD behaviors. "Friends began to shy away from us — they didn't want their children to be around him. I felt like the worst mother in the world."
An elementary school disorder?
After Brandon was asked to leave a second preschool — he'd chased a girl around the playground with a plastic knife, saying he would "cut her up" — Mary booked an appointment with her son's pediatrician to ask about diagnosing the preschooler with attention deficit disorder. Her doctor's response, however, was that Brandon was much too young for an ADHD diagnosis. And this response is one that parents of children with ADHD across the country in similar circumstances can expect to encounter. Why?
Attention deficit disorder has traditionally been viewed as a disorder of elementary school children. While there are hundreds of scientific studies generating a wealth of data for diagnosing and treating ADHD in school-age children, there are few equivalent studies about diagnosing and treating preschoolers with ADHD. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria used to diagnose ADHD include symptoms such as, "out of seat during school," "does not follow through on instructions," "avoids tasks with sustained mental effort," and "fidgety and restless while sitting"-describing behaviors that may be developmentally appropriate for some preschoolers.
Diagnosing ADHD in preschoolers
Is it possible, then, to diagnose children with attention deficit disorder when impulsivity, opposition, and extreme activity are normal preschool behaviors? Yes, but the tipping point in diagnosis is usually a matter of degree. "Children with ADHD are much more extreme than the average three-year-old," says Alan Rosenblatt, M.D., a specialist in neurodevelopmental pediatrics. "It's not just that a child with ADD can't sit still. It's that he can't focus on any activity, even one that's pleasurable, for any length of time."
Larry Silver, M.D., a psychiatrist at Georgetown University School of Medicine, says that an experienced teacher, one with a baseline of appropriate three-year-old behavior, can be a tremendous help. "You have to look at whether or not the behaviors are consistent in more than one environment," he notes.
But experts caution that, even with "red flags," early diagnosis of ADHD can be difficult. "You have to delve deep into the root of certain behaviors," says Silver. "A child might have separation anxiety, his fine motor skills or sensory problems could be making it hard for him to behave, or it could be evolving Pervasive Developmental Disorder," he says.
Nonetheless, Laurence Greenhill, M.D., of Columbia University/New York State Psychiatric Institute, points to two behavioral patterns that often predict ADHD diagnosis later in life. The first, preschool expulsion, is usually caused by aggressive behavior, refusal to participate in school activities, and failure to respect other children's property or boundaries. The second, peer rejection, is one that parents can easily identify. Children with extreme behaviors are avoided by their classmates, shunned on the playground. Other children are "busy" whenever parents try to arrange playdates.
In these extreme cases, parents should take their preschooler to a pediatrician or a child psychiatrist. Diagnosis of ADHD should involve a thorough medical and developmental history, observation of social and emotional circumstances at home, and feedback from teachers and health professionals who have contact with the child. In many cases, neuropsychological testing may be needed to rule out conditions whose symptoms might overlap with ADHD, including anxiety disorder, language-processing disorders, oppositional-defiant disorders, and sensory integration problems.
