Can narcissistic disorder be derived from lack of affection?

Narcissistic Personality Disorder (NPD) can be influenced by a variety of factors, including childhood experiences. While a lack of affection and emotional support during formative years may contribute to the development of narcissistic traits, it is not the sole cause. NPD is considered a complex disorder resulting from a combination of genetic predispositions, environmental influences, and individual temperament. Thus, while a lack of affection may play a role, it is not the definitive origin of narcissistic behavior.
