Could temporary exposure of the bbb, plus already present lyme disease, and an affected cerebellum/or not. cause anti-nmda receptor encephalitis?

Unclear on the : Whole picture you are speaking about here. One thing i can tell you, is that anti-nmda is an auto-immune based encephalitis and is not normally associated with lyme disease. I am sorry i cannot answer more, but if you clarify it a little, i will watch for your question to come back up. Thanks and i hope that helps!

Clarification needed: I have no idea what you are referring to. I assume bbb is blood-brain-barrier but I am not sure what anti-nmda receptor encephalitis is.
