I believe ignorance is a common reason even among professionals. They only think of the grandiose traits; they confuse the vulnerable traits with BPD or MDD; and they think it has to be close to ASPD to be diagnosable.
My loved one developed NPD by having a terrible childhood and early teenage years with undiagnosed AuDHD. Bullying, rejection, isolation, school failures, etc. The solution was to start lying, manipulating, trying to get something (anything) going their way, seeking validation… They received a depression diagnosis only at first 🫥.
Did you know people with ASD score higher in vulnerable narcissism traits? That means this story could be common. Traumatized neurodivergent children are already at higher risk of developing mental disorders.
But no, nobody talks about NPD this way. It’s always about grandiose traits being dangerous for others (which can be part of the experience, but there’s so much more). I hope it changes someday.
That’s not true. NPD diagnostic criteria in the DSM-5-TR (latest version) still contains manipulation efforts and similar behavior. Quote:
So… Donald Trump probably meets criteria for a narcissistic personality disorder diagnosis (if he ever agrees to start a “mental health journey”).
And it’s true that many disorders need to cause “clinically significant distress”, but personality disorders can be diagnosed even if they don’t cause distress to the person but causes it to others (e.g. ASPD). The DSM had to consider egosyntonic disorders, after all.
