Multiplex or panel-based nucleic acid amplification tests are available for testing multiple bacterial and viral pathogens simultaneously in a single CSF sample (eg, FilmArray meningitis/encephalitis panel [BioFire]). The disease is mostly associated with teratomas of the ovaries and is thus considered a paraneoplastic neurologic syndrome (PNS). It is a cytokine produced by leukocytes and other cells in the body and increases the number of blood cells being made by the marrow. 1 Multiple types of VGCCs have been described in both the central nervous system and peripheral tissue. 1 The autoimmune process was first described in 2007 when Dalmau et al.
