How can you distinguish the difference between unintelligence and add in someone?

ADD or dim. Add folks are distracted but not necessarily unable to understand concepts due to limited intelligence. They may underachieve in many arenas including school, work or in relationships - they can do it but get distracted by a hyperfocus, procrastinate, or are bored with the whole proposition. On effective treatment they can more consistently perform up to their capacities - reflecting their true iq.
