Could you tell me the signs of Narcissistic personality disorder in a woman?

The essential feature is a grandiose sense of self-importance or uniqueness. They have a constant need for attention and need to be admired. They have a sense of entitlement and react negatively to anything that threatens the image they have of themselves. The are usually unsuccessful in interpersonal relationships because they tend to exploit people for personal gain. They have been described as cold, indifferent and lacking empathy.

Their self-esteem is fragile and they need constant reassurance. When things don't go their way they become moody and depressed. If someone cancels plans because they are sick a narcissistic personality can easily fly into a rage.

They are obsessed with self-grooming and looking immaculate. They are preoccupied with staying and acting youthful. They take good care of themselves, work out and most are very attractive as a result.

Close relationships tend to alternate between idealization and devaluation. This is called "splitting". This means if you become romantically involved with her she will alternate her behavior... one day she adores you and the next day she despises you.

The narcissist can have all or just a few of these issues. Many narcissists have very successful careers, especially in business, because they can be ruthless.
