I was reading that the difference between sz and sza is that with sz, you have a more continuous psychosis pattern and that with sza, the psychosis pattern is more episodic. In other words, with sza, the psychosis starts and stops frequently. And that with sza, there are fairly long periods of mood episodes such as depression or suicidality or its opposite such as hyperactivity or mania.
This all, to me, makes perfect sense. My psychotic episodes are continuously coming and going. Although I haven’t had a mood cycle since 2016, my history is chock full of severe depression and suicide attempts with mania/hypomania here and there.
My current diagnose is frank schizophrenia, no subtypes, before that I was schizotypal, but for most of my life I was diagnosed SZA which I find the most precise diagnose. I can relate.
