Competing Interests

We have the following interests. Dr. Dalmau has a research grant from Euroimmun and receives royalties from Athena Diagnostics for a patent for the use of Ma2 as autoantibody test, and licensing fees from Euroimmun for a patent for the use of NMDAR as autoantibody test. The patents concerned are: Patent Ma2: US 6,387,639 and Patent NMDAR: US 7972796 B2. There are no further patents, products in development or marketed products to declare. This does not alter our adherence to all the PLOS ONE policies on sharing data and materials, as detailed online in the guide for authors.
