MS Phenotype Classification (McDonald / Phenotype)

Clinical classification of multiple sclerosis phenotype based on disease course (RRMS, SPMS, PPMS, CIS) using the 2013 Lublin consensus criteria.

Score interpretation

CIS — Clinically Isolated Syndrome 1

Single demyelinating event. 50–85% risk of converting to MS within 10 years.

→ MRI brain and spine. CSF oligoclonal bands. Commence DMT if high-risk MRI lesions (McDonald criteria met). Neurology follow-up.

RRMS — Relapsing-Remitting MS 2

Discrete relapses with remission between attacks. Most common form (~85% of diagnoses).

→ DMT selection based on disease activity and patient preference. MS specialist review. Relapse management with steroids.

SPMS — Secondary Progressive MS 3

Gradual accumulation of disability following RRMS phase.

→ Siponimod (active SPMS) or cladribine. Rehabilitation. Symptom management. EDSS monitoring 6-monthly.

PPMS — Primary Progressive MS 4

Progressive disability from disease onset with no clear relapses.

→ Ocrelizumab (ofatumumab for active PPMS). Physiotherapy. Neurorehabilitation. Symptom management.

Interpretation bands for the MS Classification. Apply clinical judgement and local guidance.
