Briefly, patient 1 was diagnosed with generalized MG at the age of The authors suggest that the association might be caused by subclinical systemic lupus erythematosus in three of them due to the presence of antinuclear antibodies, including both cases with recurrent DD, although this has been contested due to the fact that two of their patients could actually have NMO In addition, supportive criteria include raised CSF proteins and segmental and multifocal demyelination in nerve biopsy in clinically suspected SIDP cases in which electrophysiological proof of demyelination is absent.

Onset can occur at any age but is more common between the 4th and 5th decades. Does myasthenia gravis affect the brain?
