Abstract: A technique for determining a state of MS (Multiple Sclerosis) in a MS patient, for example Relapsing-Remitting MS (RRMS) or Secondary Progressive MS (SPMS) or an in-transition from RRMS to SPMS state, is presented. In the technique, patient data and age of the patient, and optionally EDSS score and/or T25FW score, is inputted by a user to a processor. The patient data queries comprise items grouped into a first group relating to relapse and recovery, a second group relating to symptoms experienced and a third group relating to impacts experienced by the patient in a predetermined period. Each item has an assigned predetermined weight and comprises a plurality of corresponding predetermined responses. Each response has an assigned predetermined score. Predetermined weights are also assigned for age query and to the EDSS query and/or the T25FW query.
