Can narcissists be considered psychotic?
This is a decently interesting question. To start out, let's throw the definition of psychotic out there. So psychotic originally derives from the mental illness known as psychosis. Yes, it is its own thing, it's separate from other mental illnesses such as psychopathy and schizophrenia. It can occur alongside other disorders, but it's a whole other disorder. In modern media, being psychotic or psycho is usually perceived as someone going completely crazy, acting crazy, being aggressive and generally insane. That's not actually the real definition of psychosis or psychotic. Psychosis can involve delusions, hallucinations, and essentially the person loses the sense of reality and what's around them.
Psychotic and psycho aren't words that get a good rep in the mental health community, and hopefully it's obvious why, so if not, here you go. It's not pure craziness or something inherently evil, it's a symptom of a disorder that's blown out of proportion and stigmatized in media.
Alright, so, I don't have psychosis, and I'm not a professional, so if I get anything wrong, someone yell at me. So class, as we've learned in my earlier terribly written paragraphs, psychosis is its own mental disorder, meaning that it isn't a "side effect" so to say of NPD. As far as I can tell, they're fairly unrelated. NPD does come with delusions of grandeur in some cases, but those are different than psychosis delusions. So no, narcissists aren't inherently "psychotic" in the actual definition of the word. Yes, a lot of us are capable of actions that may seem "psychotic" in the stigmatized definition of the word, but that most likely has nothing to do with literal psychosis. Can someone have NPD and psychosis at the same time? I obviously can't speak from experience, but it seems so from my researching.
What I can say from personal experience is that yes, I have shown some behaviors that can be considered "psychotic", mainly when I completely lose my temper/feel threatened. I'm generally irritable most of the time, and I range from annoyed to angry on a typical day. However if someone insults me enough or basically pushes all the right buttons, I do somewhat snap. Basically it's me yelling at the top of my lungs, throwing random insults, sometimes laughing because I'm weird like that, and yes, it's not pretty. I've never gotten inherently physical with anyone because I'm small and over half of the population can kick my ass, so just throwing that out there. In the case of others, yes, physical reactions can happen. However, that's not psychosis, that's actually mania. It would be closer to a manic reaction, due to the heightened energy, emotional spikes, and out of control compulsions as opposed to hallucinations or loss of reality. Some of it for me personally also has to do with being bipolar, which involves mania a lot.
For most narcissists, our most over the top reactions happen when people we've deemed lower than us stand up to us, or fight back to the point of hitting a nerve. Am I sensitive, fairly yes. If someone were to combat me enough and say the right things, my sense of superiority would be threatened and I'd be willing to do anything to protect it. In my mind, it's to remove or crush the source of the problem, being a person usually. So, like the rabid little attack dog I am, I lash out. And some days I'll freak out for no reason, or because of a very small reason, and I can say that's more of my bipolar disorder than NPD.
So overall, can narcissists be considered psychotic? In the mental health sense of the word, I'm going to say no, as NPD by itself doesn't normally include any symptoms of psychosis. Can someone with NPD also have psychosis? I'm going to say yes for that. Can narcissists act "psychotic" in the stereotypical sense? Yes, I believe anyone can honestly, but we have more specific triggers for that kind of response.
So that was a rollercoaster. This did involve a little more research on my behalf, so I can place my sources if needed. Again, I know next to nothing about psychosis so someone yell at me if I did it wrong. And disclaimer that I forgot to put up at the top again, I can't speak for everyone's experience, hence my overuse of words like generally, possibly, most likely, ect ect. So yes, there you go. Thank you for the ask, I hope this at least sounds like a recognizable human language.
