We hypothesize that elevated body and brain temperature in patients with relapsing-remitting multiple sclerosis (RRMS) indicates clinically-silent disease activity, i.e., inflammatory processes. MRS thermometry was used to measure brain temperature in RRMS and progressive-type MS patients. Brain temperature was elevated in RRMS patients relative to progressive-type patients. Monitoring brain and body temperature may allow us to detect clinically-silent inflammatory processes in patients with RRMS.
