The increase in MG incidence in the very old is probably caused by unknown environmental factors. Both patients' and doctors' diagnostic delays are substantial for very late onset MG. Comorbidities are frequent and can lead to misdiagnosis. MG needs to be considered as a potential diagnosis in all elderly patients with newly localized or generalized muscle weakness. AChR antibodies have near 100% diagnostic specificity and 80% sensitivity in this age group. Very late onset MG is often mild and with an excellent response to pyridostigmine and first\u2010line immunosuppressive therapy. One in five has a debut with life\u2010threatening respiratory insufficiency. Rituximab, complement inhibitors, and FcRn blockers can be used on the same indications as for younger MG patients. MG in the very old is a fluctuating disease with the need of frequent adjustments of drug therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Very late onset MG and MG in the very old should be treated actively with symptomatic and immunosuppressive drugs, physical activity programs, and general support.
