This document discusses the relationship between giftedness and several psychological conditions including ADHD, narcissism, obsessive-compulsive disorder, and antisocial behavior. It provides the DSM criteria for some of these conditions and notes areas of overlap as well as ways to differentiate them from giftedness. Specifically, it notes that gifted individuals may display some similar traits as those with conditions like OCD but the level of impairment is usually different and their behaviors are often directed towards a positive end rather than being unproductive or self-critical.
