symptoms occur after the disease progresses and there is much more damage to the myelin sheaths in the peripheral nervous system. These can present as debilitating tremors that prevent patients from doing normal tasks, complete sensory loss on limbs, and, in some cases, extensive muscle atrophy. Diagnosis Detection of this type of neuropathy has concentrated mostly on detecting presence of antibodies because the antibodies are the main cause for the disease. Anti-MAG antibodies can be readily detected in a patient's sera using various types of assays, but mainly an ELISA has been shown to be most effective. There are also various biological indicators, such as elevated cerebral spinal fluid proteins and elevated IgM monoclonal levels. These can also be tested either by drawing serum from a patient or by drawing spinal fluid from a spinal tap and testing using an assay or blot. Treatments Drug and therapeutic treatments exist in order to battle this disease; though many have proven ineffective. Immunotherapy and chemotherapy While immunotherapy works for some patients in relieving minor symptoms, overall most conventional therapies using steroids, immunosuppressants, chemotherapy, and intravenous immunoglobulin therapies have not helped most patients. This has created a need for newer and more novel therapies to be developed. Chlorambucil and prednisone Chlorambucil is a chemotherapy drug normally used to treat leukemia as it is often used as an immunosuppressant drug, and prednisone is a steroid that has also been found to be particularly effective as an immunosuppressant. This combination of drugs has minimal to no benefits in most patients, but a small number do see small improvements such as decreased tremors. This combination has not been very effective in more severe cases, though, and is not considered a long term therapy. Cyclophosphamide Cyclophosphamide is a drug often used in the treatment of lymphomas and works by slowing or stopping cell growth. It also works as an immunosuppressant by decreasing the body's immune response to various diseases and conditions. This drug has been found to make significant improvements in people with anti-MAG neuropathy by relieving sensory loss and helping to improve quality of life in a few short months. There is, however, a risk of cancer because of this treatment and is therefore not used on a regular basis. Fludarabine Fludarabine is a drug normally used to treat hematological malignancies and acts as an immunosuppressant. It has been shown to significantly improve conditions in neuropathy
