Are nmda receptors destroyed when u have anti-nmda receptor encephalitis..or do nmda receptors just become dysfunctional (over/under active)or both?

Anti-NMDA receptor e: The disease is associated with tumors, mostly teratomas of the ovaries, and is considered a paraneoplastic syndrome. However, there are a large number of cases with no detectable cancers. It is not clear what exactly takes place, but since many patients recover entirely, often when the cancer is treated, the receptors have obviously not been destroyed.
