Motor neuropathies and antiglycolipid antibodies.

This paper describes patients with demyelinating motor neuropathies associated with conduction blocks, pure motor neuropathies and intermediate forms with resemblances to amyotrophic lateral sclerosis, in persons with raised titres of anti-GM1 antibodies. The specificity of the abnormal anti-GM1 antibody titres is discussed, and the possibilities of immunosuppressive therapy mentioned.
