i had a patient recently who was blatantly psychotic. she was preaching to an imaginary croud, loud as hell, and bizarely delusional. she kept on inviting us to her wedding for that evening...telling us that we were blessed, we were going to be involved in the wedding etc etc....and of course, she was getting married to jesus. i dont recall her endorsing any hallucinations, but she was extremely tangential, and speaking in gibberish language intermittently. Neologisms, right? anyways...someone brought to my attention that in the pentacostal church, her speech is known as 'speaking in tongues' and that only people who have a direct connection with 'god' , are capable of this language. of course, the only way to confirm this is if you infact are connected with god, b/c it cant be proved/disproved by others. so my question is...can i describer her speech as widespread use of neologisms? is the use of a language in which no one else can prove/disprove, delusional? i guess it wouldn't be a bizzare delusion because its not that hard to believe...., versus someone saying that they are speaking in an undecipherable langugae that was taught to them by a tree...for example any thoughts...on delusions, hyper-religiosity, and their boundaries ... also is there any literature on the prevelance of psychotic illness/behavior in those who are fanatical about religion?
