NMDA receptor encephalitis is usually associated with a particular ovarian tumor, so the first thing I did on seeing this article was to check if the author is male or female (he's male). It is the habit of certain cancers to present with bizarre symptoms (so-called paraneoplastic syndromes) including psychosis as in this case, and often it can be months before someone thinks to look for cancer. I'm glad the author's okay.

Yes! No tumor. I've had a PET scan and a testicular ultrasound. I think that puts me in the idiopathic category for this particular case.
