Greg, 11, hаs а number оf distrаcting behaviоrs that have increased in severity fоr the past five years. The boy’s behaviors are more prominent under stress or when he is in the classroom. Ms. Anita, his teacher, indicates that Greg’s behaviors are very problematic in the classroom. The teacher indicates, “Greg seems to be doing all these things to get attention. He has a number of head movements that are very disturbing. He twists and turns his head and blinks his eyes like he is imitating a lizard. He makes grunting sounds and little blowing sounds that make me very irritated. I am very concerned that Greg keeps his friends from focusing on the lesson. When I call on him sometimes he whistles. I know that this is something he can control.” You diagnose Greg with what condition?
