There are four general Multiple Sclerosis types (or phenotypes), including clinically isolated syndrome, relapsing-remitting, secondary progressive, and primary progressive.
There are also suggested modifiers that can be applied (that work across a timeframe), such as “activity” and “progression,” with the latest guidance suggesting the terms “worsening” or “progression” to describe the condition. It is uncertain how a patient’s condition will progress.
Clinically Isolated Syndrome (CIS) is an initial episode of MS-like symptoms lasting at least 24 hours. It could indicate a risk of future MS development. It's a precursor, not a definitive diagnosis.
MS may present as relapsing-remitting or progressive forms.
