<unk>  are diagnostic criteria that were previously used for identifying multiple sclerosis (MS). Multiple sclerosis, understood as a central nervous system (CNS) condition, can be difficult to diagnose since its signs and symptoms may be similar to other medical problems. Medical organizations have created diagnostic criteria to ease and standardize the diagnostic process especially in the first stages of the disease.<unk>  were the first internationally recognized criteria for diagnosis, and introduced concepts still in use, as CDMS (clinically definite MS). Sometimes it has been stated that the only proved diagnosis of MS is autopsy, or occasionally biopsy, where lesions typical of MS can be detected through histopathological techniques, and that sensitivity and specificity should be calculated for any given criteria
