Symptoms include difficulties with attention, concentration, and short-term memory as well as impulsivity. Children with ADHD are overly active (as if “driven by a motor”) and cannot control ongoing activity ranging from fidgeting to difficulty remaining seated for 5 minutes to inappropriately running, jumping, and yelling in public places. Since these deficits significantly impair academic performance and are disruptive in a typical classroom, concerns about ADHD usually arise during kindergarten or first grade. However, ADHD is a lifelong condition with functional impairment extending throughout adulthood.
