Looking to learn more about OCPD. My 87-year old father has recently started treatment for psychotic/paranoid delusions, but the underlying issue may be OCPD. He has exhibited at least 5 of the 8 DCM-V listed characteristics for OCPD for as long as I can remember. The delusions seem more like his latest thing to obsess about, as opposed to someone who is psychotic in a much more general sense. I am finding it challenging to locate much info on OCPD except highly technical articles. Any help appreciated!
