Bickerstaff Encephalitis and GBS?

Did anyone have Bickerstaff encephalitis at the same time as their attack with GBS? I have read on the web that it is closely associated to GBS (and Miller Fisher).

**I have been speaking to someone who has a family member who apparently has both, and I said I would ask the forum members if anyone has had the two together. I vaguely remember having discussions regarding encephalitis, not sure it was Bickerstaff tho, but when I search the topic I dont find anything similar to what I was thinking about. Could it have been on the old forum?**
