Hyperactivity—Behavioral Issues in Child Care and Schools

Hyperactivity is typically thought of as one part of attention-deficit/hyperactivity disorder (ADHD), which can be diagnosed in children as early as age 4 years. However, because most preschoolers can be active and inattentive and have difficulty staying engaged at times, only medical and/or mental health professionals should establish the diagnosis after carefully receiving input from parents or guardians and teachers.
