A member of my dp's family is currently an involuntary patient in a psychiatric unit. I am on file as his next of kin (long story) He is experiencing acute psycosis and they have said that at the moment they have "a working diagnosis" of delusional disorder. I have read a good bit of what I can find on the Internet about this condition. I was wondering if anyone here could offer any information or experiences of this or recommendations of things to read in relation to this. Thanks in advance for any info or suggestions.
