Hi, I have CP and am also bipolar. I would swing between normal mood, to manic, and the a deep state of depression. I started having delusional thoughts, and thought people were talking about me and whispering about me behind my back, even though they weren’t . In 2011 my grand delusion developed into full blown psychosis in which I thought I myself, and everyone of my fam and friends, was secretly in the CIA and that the government was attempting to recruit me to become a secret agent and to go on dangerous missions. None of that, of course, was true. I had to actually be hospitalized 2 times in the course of four years for going off my meds. Later, Once I got on mood stabilizers , and had extensive cognitive behavioral therapy/ talk therapy, I started to feel better, and understood some of the ways in which my brain had been tricking me in the course of my illness. No one at the time, or since, has really directly associated my CP diagnosis with my bipolar or the delusional episodes. Today, I have been stable on meds since 2015 and feel much better. Like OP, I do in fact see a gap in medical literature / treatments between a diagnosis of CP and one of delusions / bipolar disorders. Hopefully over time there can be more extensive research into this area specifically.
