Conventional Markers of CNS inflammation.

	NI (N = 5)	OAND (N = 5)	AbPAE (N = 9)		AbNAE N = 23
	n (%)	n (%)	n (%)	p	n (%)	P
CSF monocytosis > 5 (2)	0 (0%)	1 (20%)	2 (22%)	n/a	4 (17%)	n/a
CSF oligoclonal bands	0 (0%)	3 (60%)	6 (67%)	n/a	5 (22%)	n/a
CSF protein > 0.45 g/L	3 (60%)	2 (40%)	4 (44%)	0.5	9 (32%)	0.6
Neuronal IIF (any staining)	1 (20%)	2 (40%)	n/a	n/a	8 (35%)	0.4
MRI changes	n/a	4 (80%)	3 (33%)	n/a	5 (22%)	n/a

P-values are calculated as AbAE or AbNAE vs. all other control groups (NI, viral and OAND).
