Five Years Before Multiple Sclerosis Onset: Phenotyping the Prodrome

In medicine, a prodrome is an early sign or symptom, which often indicate the onset of a disease before more diagnostically specific signs and symptoms develop. It is derived from the Greek word prodromos, meaning "running before". Prodromes may be non-specific symptoms or, in a few instances, may clearly indicate a particular disease, such as the prodromal migraine aura.
