Predominance of women affected, as in rheumatoid arthritis and systemic lupus erythematosus |
Predominance of women also seen in non-autoimmune disorders such as migraine |
Association of other autoimmune diseases in affected individuals and families |
Not proven in large epidemiological studies of MS |
Association with HLA haplotypes |
The strongest HLA links are observed with hereditary haemochromatosis and narcolepsy, metabolic and neurodegenerative diseases respectively |
Antimyelin antibodies in serum |
Antimyelin antibodies can be detected in neurological disorders other than MS, and some antimyelin antibodies have a reparative function |
Oligoclonal bands in cerebrospinal fluid |
These bands are reported in other neurological diseases such as subacute sclerosing panencephalitis and neurosyphilis, conditions that are not autoimmune. Oligoclonal-band-negative cases of MS have been reported |
Specific T-cell response identified during MS relapses |
No T-cell response is unique or specific in MS |
Partial therapeutic response of relapses to beta-interferons, glatiramer and other immunotherapies |
Relapse prevention in MS may not translate into disability prevention. No immunotherapy has reduced long-term disability in MS |
