Types Of Multiple Sclerosis
There are four main types of multiple sclerosis; Relapsing-Remitting MS (RRMS) is the most common type. It occurs when the disease temporarily becomes active and then goes into remission. Secondary-Progressive MS (SPMS) occurs when symptoms start to become worse over time. Primary-Progressive MS (PPMS) is the least common and happens when MS symptoms slowly become chronic. The final stage is Progressive-Relapsing (PRMS), which is very rare and occurs when the disease consistently remains active with no periods of remission.
