Egomania is also known as an obsessive preoccupation with one’s self^[1] and applies to someone who follows their own ungoverned impulses and is possessed by delusions of personal greatness and feels a lack of appreciation.^[2] Someone suffering from this extreme egocentric focus is an egomaniac. The condition is psychologically abnormal.^[1]

The term egomania is often used by laypersons in a pejorative fashion to describe an individual who is intolerably self-centred. The clinical condition that most resembles the popular conception of egomania is narcissistic personality disorder.^[3]
