On other matters, Racer my old friend; Deb is right, the pathways of the spinal cord are myelinated. Sigrid, unfortunately that is not strictly true, some with CIDP do in fact have plaques in brain and/or spinal cord tissue. The significance is unknown and their development is unrelated to either the symptoms nor the severity of the CIDP. But I suspect may be one of the causes of confusion over the diagnosis of MS versus CIDP. DocDavid.
