What's my diagnosis?Explain in detail how you arrived at the diagnosis after reading this passage and your text.

John is a 10-year-old child who is currently repeating the third grade. His teachers have requested that his parents have John evaluated for possible ADHD. At school John talks excessively, is frequently out of his seat, and his teacher describes him as, at times, so difficult to control that she "can't get a word in edgewise." His teacher reports that when John is very active it is as if he has a "motor" inside. He can also be somewhat irritable, "fidgety," and has difficulty not interrupting the other children. His teacher notes that she likes the fact that when John is like this that he believes he can be the best student in her class and focuses more on his assigned tasks. At home, his parents report few problems. They acknowledge that he is extremely active at times but report that they send him outside to play and that he will eventually "wear himself out." His parents report that John sometimes has difficulty playing by himself quietly. Once again, when this is a problem, they simply send him outside to play. Finally, they report that John may simply be one of those children who don't need much sleep. When he is very active he may sleep only a few hours each night, spending the rest of the time working on his "special projects" to catch up at school.
