Narcissistic Personality Disorder (NPD) is a complex mental health condition characterized by an inflated sense of self-importance, a deep need for excessive attention and admiration, troubled relationships, and a lack of empathy for others. People with NPD often present a facade of extreme confidence, but beneath this lies a fragile self-esteem vulnerable to the slightest criticism. The question of whether narcissism is genetic or purely a product of environment is a topic of ongoing research and significant debate.
