As narcissists age, their behaviors may become more extreme or entrenched. They may become more rigid in their thinking and less willing to adapt to changing circumstances. In some cases, their behavior may become more aggressive or abusive as they feel increasingly threatened by their loss of control or power.

However, aging can also bring about some positive changes in narcissists. As they confront their own mortality and face the challenges of aging, some narcissists may begin to develop a greater sense of empathy or humility. They may start to prioritize their relationships and seek out more meaningful connections with others.

Ultimately, the way that aging affects narcissists will depend on a variety of factors, including their individual personality traits, their life experiences, and their willingness to engage in self-reflection and personal growth.
