ADHD: Inability to achieve to your capacities, procrastination, lack of foliow-through on mundane or boring tasks (unless at the absolute last moment), hyperfocus on activities that interest one (to a fault - ignoring important deadlines, staying up very late or absorbing a grab deal of time in the activity, missing meals, peer alienation), problems with time management/organization, and impatience.

ADHD: The criteria can be more objectively measured by using the asrs - a widely available instrument. It is suspected when students underachieve - perform worse than iq/achievement testing would suggest or are inconsistent. The impact can be evident at home with poorer self-esteem and rejection - by parents and friends. Heightened impulsvity, hyperactivity, fidgetiness, and disruptiveness are typical.

Great caution is recommended when using the ASRS alone (self-report / self-reported survey). This insrument is a screen test only/ It has high sensitivity but limited specificity with relatively unimpressive positive predictive value. Perfect screener, but never a diagnostic entity alone. Too many other conditions will score positive on ASRS so always look for congruent data before Dx.

DSM-IV TR currently: The diagnostic & statistical manual of the amer psych assoc, fourth edition, revised (dsm-iv tr) is the internationally accepted provider of psychiatric diagnostic criteria. As such the basic definition of ad/hd is given in that manual. These are the minimum criteria to make the diagnosis for physicians to follow. See http://www.Psychiatry.Org/practice/dsm/dsm-iv-tr.
