What Causes Narcissistic Personality Disorder?

According to research, narcissistic personality disorder is present in 5% of the population in the U.S.

It’s just a small percentage, yet it’s something worrying! We’ve seen a lot of articles lately based on this topic, and if you’re a subscriber, you probably read many from our page too. However, we will be “sitting on it for a while” because it is a vast topic to investigate and the subject of many research papers.

This time around we will talk more about narcissistic personality disorder and what may cause it, how it affects a person’s self-esteem and identity, and most importantly, how they end up treating the others around them because of this condition.

It is generally acknowledged that a variety of factors can influence a person’s lifetime risk of developing NPD, and the possible causes of narcissistic personality disorder are listed below:

What is narcissistic personality disorder?

This term comes from the Greek, Narcissus, a hunter from mythology. The myth states that Narcissus was unable to stop staring at his reflection in a pool of water because his beauty so consumed him. Until he passed away, he did nothing but gaze at his reflection.

This is why people think that the term narcissism is associated with physical appearance, but in reality, this is just a tiny bit of what it really means. Intelligence, charm, artistic talent, athletic prowess, wealth, power, success, and more fall under the umbrella of what NPD is.

Furthermore, an excessive need to feel significant or impress others is a sign of NPD. That need may be powerful enough to motivate destructive actions that harm both you and those around you.

    I have been married to the same man for 45 years, and he is definitely a narcissist. He is extremely controlling, doesn’t know how to apologize/provide encouragement//give compliments to me or our children. On the other hand, he is giving and has always been an amazingly generous provider.

      Sorry this has happened to you. I’m sorry to say sometimes it’s best to walk away from people like this . Money isn’t everything nor is DNA. Leave your family behind you. Move far away and live your best life. You deserve to be happy. And please use periods when you write.
