Mutifocal Motor Neuropathy (MMN) is an inflammatory nerve disease affecting the myelin sheath, or
the insulation of nerves, similar to CIDP and GBS. It typically has a slow course over many years and
affects the arms with weakness in the muscles that bend the fingers, however any nerve and muscle
group can be affected. On nerve testing (EMG), “blocking” of the responses to the nerves which go to
the muscles is seen. Sometimes, antibodies to a molecule called GM1-ganglioside are present and can
be detected with additional testing. This can help with the diagnosis.
– Intravenous immunoglobulin (IVIG)
– Plasma exchange
– In contrast to CIDP, MMN is not usually responsive to medications such as prednisone or other
The GBS/CIDP Foundation of Canada is a registered Canadian Charity. Our Foundation is made up of trained
caring volunteers who have had GBS, CIDP and variants, who are dedicated to the support of our patient
community in hopes that no patient goes through these disorders alone. Our mission is that of Support,
Education, Research and Advocacy.
If you or someone you know would like more information, please contact the Foundation. Medical
professionals are welcome to contact us for literature and to get more information on how to connect
your patient with the foundation.
