Some people with lupus can develop mild or, more rarely, severe inflammation of the brain, also called Central Nervous System lupus (CNS lupus). Very rarely, people can develop serious problems from CNS lupus such as seizures or strokes. Sometimes it is hard to know the difference between CNS lupus and problems that might be due to fatigue, depression, or migraine headaches. Therefore, it would be helpful to have blood tests that could tell the difference, so appropriate treatments could be given.
