"If you are experiencing symptoms of impulsivity and/or hyperactivity that are impacting your quality of life and ability to focus at work or in school, you may need to be evaluated for ADHD.ttention Deficit Hyperactivity Disorder, or ADHD, is defined as an ongoing pattern of inattention, impulsivity, and hyperactivity that greatly affects daily life. Most everyone experiences an extent of impulsive decision making and difficulty remaining focused on a task. However, a person living with ADHD experiences these difficulties with more severity. ADHD is a developmental disorder, meaning that adults with ADHD have had the condition since childhood, whether they realized it or not. ADHD symptoms are often harder to detect in adults because they appear in more subtle forms, or because the symptoms have become more manageable in adulthood."
