In my case, the misdiagnosis up front was entirely reasonable. (EDIT: Well, maybe not. See below.) The generalized anxiety disorder diagnosis from my PCP made a lot of sense given what was happening. I hadn't had delusions yet at that point. It was... a mixture of panic attacks, night sweats, jaw pain and a greatly increased level of anxiety compared to my baseline.

My PCP did run a bevy of tests (chest x-ray, and took tons of blood) to try and rule out anything biological.

Given what was known at the time, I think my PCP did the right thing. And when my symptoms really escalated (delusions, suicidal ideation, falling and hitting my head), my PCP suggested going to an ER. And that's what we did.

I think it was the ER that really dropped the ball. Given the sudden onset of everything, the fact that they didn't get me in front of a neurologist is, in retrospect, really quite baffling. That's when I went to a psychiatric hospital, where I spent 3 nights.

I only got out of that hospital due to total luck. My neighbor was old college buddies with a neurosurgeon. (We had no idea about it. It just came up randomly when my neighbor was dropping my son off at home for us.) That was the critical connection because he ended up talking to the neurology department at Brigham and Women's, then talked to the psychiatric hospital and was the one who facilitated my transfer.

My wife tried to do it on her own but they wouldn't allow it because I had been medically cleared. She had to give 3 days notice to pull me out. Or otherwise, by default, I would see a neurologist after 2 weeks. According to the psychiatric facility.

I really don't know if I would have made it that long. The encephalitis wouldn't have killed me in that span of time, but I was in an extremely dark place.

I'm also really lucky that this is an autoimmune disorder that has a pretty objective diagnostic criteria: a positive antibody test in your cerebral spinal fluid. You "just: need to have your spine tapped to get that though. Fun times.
