Predominantly hyperactive/impulsive type. The student may: o Appear to be in constant motion, o frequently fidget or move in his or her seat, o become restless during quiet activities, o leave his or her seat when expected to remain seated, o interrupt others and classroom activities, o talk excessively, and/or o fail to follow classroom procedures (e.g., blurt out answers without raising hand). Combined type. The student may exhibit symptoms that include behaviors from both categories above. For a student to be diagnosed with ADHD, symptoms must appear before age 12 and be exhibited across at least two settings. They must also have adverse effects on academic performance, occupational success, or social-emotional development (APA, 2013). To add to the complexity of the diagnosis, children with ADHD are likely to have co-existing emotional, behavioral, developmental, learning, or physical conditions (Wolraich & DuPaul, 2010).
