Oh my my.
I listened to the first three minutes of Charlie Sheen's 7 minute radio rant. He sounded exactly like someone I know who is undx'd bipolar but who also seems to have some narcissistic personality traits.
Charlie had tested clean for that interview.

Diagnostic criteria (DSM-IV-TR = 301.81)

The Diagnostic and Statistical Manual of Mental Disorders fourth edition, DSM IV-TR, a widely used manual for diagnosing mental disorders, defines narcissistic personality disorder (in Axis II Cluster B) as:[1]

A pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy, beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:
~Has a grandiose sense of self-importance (e.g., exaggerates achievements and talents, expects to be recognized as superior without commensurate achievements)
~Is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love
~Believes that he or she is "special" and unique and can only be understood by, or should associate with, other special or high-status people (or institutions)
~Requires excessive admiration
~Has a sense of entitlement, i.e., unreasonable expectations of especially favorable treatment or automatic compliance with his or her expectations
Is interpersonally exploitative, i.e., takes advantage of others to achieve his or her own ends
~Lacks empathy: is unwilling to recognize or identify with the feelings and needs of others
~Is often envious of others or believes others are envious of him or her
~Shows arrogant, haughty behaviors or attitudes

I was struck by how much he sounded like the person I know in real life -- full of himself, thinks he is smarter than everyone else, lacks compassion, . . .
