Multiple sclerosis (MS) is categorized into several types, each representing a different pattern of disease progression:
1. Clinically Isolated Syndrome (CIS): This is a first episode of neurological symptoms caused by inflammation and demyelination in the central nervous system. CIS may or may not progress to MS.
2. Relapsing-Remitting MS (RRMS): This is the most common form of MS. People with RRMS have episodes of new or worsening symptoms (relapses), followed by periods of recovery (remissions).
3. Primary Progressive MS (PPMS): About 15% of people with MS have PPMS. This form is characterized by worsening neurological function from the onset of symptoms, without early relapses or remissions.
4. Secondary Progressive MS (SPMS): In SPMS, individuals initially have RRMS which then becomes progressively worse, with or without occasional relapses, minor remissions, or plateaus.
5. Progressive-Relapsing MS (PRMS): This is a rare form of MS characterized by a steadily worsening disease state from the beginning, with acute relapses but no remissions.
Each type of MS can show different patterns on MRI scans and is assessed using the Expanded Disability Status Scale (EDSS) to measure disease progression.
