Sjogren’s diagnosis often comes very late in people with POTS and other neurologic Sjogren’s features without sicca symptoms at the onset. They may be negative for SS-A and other antibodies associated with Sjogren’s.. And so, Sjogren’s diagnosis may not be thought of, without obvious sicca. Does a POTS patient with Sjogren’s is likely to benefit from immunotherapy?
Can any nerve conduction studies evaluate dysautonomia?.
