ADHD Attention Deficit Hyperactivity Disorder and Attendtion Deficit Disorder ADD
Attention Deficit/ Hyperactivity Disorder (ADHD) is a brain disorder marked by an ongoing pattern of inattention and/or hyperactivity or impulsivity that interferes with functioning or development. Inattention, impulsivity, and hyperactivity are key behaviors of ADHD. Some people with ADHD have problems with only one of the behaviors, while others have both inattention and hyperactivity/impulsivity. Most children with this diagnosis have the combined type of ADHD.
In preschool, the most common ADHD symptom is hyperactivity. It is normal to have some inattention, unfocused motor activity and impulsivity at this age, but for those with ADHD, these behaviors are more severe, occur more frequently, and interfere with or reduce the quality of how they function socially, at school, or in a job.
