Key Considerations for MS Treatment After Age 65
• Immune systems naturally weaken with age (immunosenescence), so the risk-benefit ratio of many high-efficacy DMTs shifts: infection risk ↑, while new MRI activity and relapse rates usually ↓ significantly in older patients.
• Most clinical trials excluded patients >55–60, so data in ≥65 are largely from registries, real-world cohorts (e.g., MSBase, North American Registry, French/Italian cohorts), and post-hoc analyses.
• Consensus statements (AAN 2018, ECTRIMS/EAN 2022, NMSS 2023 expert panel) generally recommend individualized decisions and often de-escalation or discontinuation in stable patients >60–65.

Multiple Sclerosis Medication in Patients Over Age 65
Multiple sclerosis (MS) is increasingly common in older adults due to improved life expectancy and better disease management, with peak prevalence now in the 55–65 age group in many regions. Approximately 10% of people with MS in the US are over 65, and this proportion is growing. However, treatment decisions for this group are complex because most clinical trials have historically excluded those over 50–55, leading to limited evidence on efficacy and safety. Decisions should always be individualized, weighing factors like disease activity (e.g., relapses, MRI lesions), comorbidities (e.g., cardiovascular disease, osteoporosis, cancer), polypharmacy risks, and immunosenescence (age-related immune decline that may reduce both MS inflammation and drug effectiveness). There are no specific evidence-based guidelines for MS treatment in those over 65, but expert consensus emphasizes a personalized approach, prioritizing symptom management and quality of life over aggressive disease-modifying therapies (DMTs) in low-activity cases.

At first when some of us reached age 60 we were told to stop DMTs because the research did not include seniors. That has changed .

My Neurologist has said to me that after 10 years of my MRIs showing no significant changes and me being in my sixties we would discuss stopping DMT medication since your immune system naturally winds down with age. With that said if you are still showing disease activity I doubt they would discontinue DMTs

There are any who make it with only mild symptoms to 60s..
