Expanded Disability Status Scale (EDSS)

Quantifies neurological disability in MS patients on a 0-10 scale. Used to monitor disease progression and guide disease-modifying therapy decisions.

Score interpretation

Mild disability (EDSS 0-3)

→ High-efficacy DMT for active RRMS (natalizumab, ocrelizumab, alemtuzumab); or moderate-efficacy (interferon, GA, teriflunomide); annual MRI; lifestyle: exercise, vitamin D, smoking cessation

Moderate disability (EDSS 3.5-6)

→ Reassess DMT efficacy; escalate if breakthrough disease; physiotherapy; bladder management; fatigue management; occupational therapy; maintain highest possible function

Severe disability (EDSS 6.5+)

→ Symptomatic management priority; spasticity (baclofen, botulinum); bladder (oxybutynin, ISC); pain (amitriptyline, gabapentin); wheelchair assessment; carer support; palliative input if EDSS >=9

Interpretation bands for the EDSS Score. Apply clinical judgement and local guidance.
