Could a blood marker add context to MRI findings in MS? A study looked at neurofilament light (NfL), a marker of nerve-cell injury, in people with early MS starting interferon. Researchers found that baseline NfL was related to disease activity, but it did not independently predict long-term progression after MRI results and other factors were considered. NfL changes over time may offer additional clues.
