Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is an inflammatory disorder of the
peripheral nerves. There is an increasing weakness as well as numbness and tingling of the legs and
arms which can develop over a period of a few months and symptoms continue if untreated. It is
caused by damage to the covering of the nerves, called the myelin. If treated early and aggressively,
therapies can limit the damage to the nerves and contribute to a better quality of life.
Like GBS, CIDP can start at any age and with either gender.
Acquired Motor Sensory Neuropathy (AMSAN), also known as Lewis Sumner Syndrome is often
considered a variant of CIDP. It shares many features CIDP but typically has a more asymmetric (More
side to side differences), and multifocal (specific areas affected) presentation compared to patients with
– Immunotherapies, such as IVIG
– Plasma exchange
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.
