The clinical features and course of the condition, the associated auto-antibodies against relevant antigens, and the response to treatment, all suggest that<unk>  is an autoimmune disease. However, each of these criteria fails to fit a substantial proportion of patients, and there is no single test or feature which is diagnostic of<unk> . It is, therefore, possible that a proportion of cases are due to other causes, such as infection or lymphoma, but remain undiagnosed. It is also possible that there is more than one autoimmune disease that can cause an illness that would currently be diagnosed as<unk> 's. There is certainly overlap between Guillain–Barré syndrome, Miller Fisher syndrome and<unk> , as well as other conditions associated with anti-ganglioside antibodies such as chronic ophthalmoplegia with anti-GQ1b antibody. and the pharyngo-cervico-brachial variant of GBS.
