That's a really important question. PIRA (Progression Independent of Relapse Activity) is a slow, silent form of MS progression that happens outside of relapses. Unfortunately, there's no clear evidence that PIRA simply "stops" on its own — it tends to be an ongoing process, though its pace varies from person to person.

That's a really important question. PIRA (Progression Independent of Relapse Activity) is a slow, silent form of MS progression that happens outside of relapses. Unfortunately, there's no clear evidence that PIRA simply "stops" on its own — it tends to be an ongoing process, though its pace varies from person to person.

What makes PIRA tricky is that it's linked to low-level "smoldering" inflammation in the brain and spinal cord, which can quietly cause damage over time even when MS appears stable on scans. The good news is that PIRA isn't something you're powerless against. There are ways to slow it down:

- High-efficacy disease-modifying therapies (DMTs) — Starting these earlier in the disease appears to have the biggest impact on slowing PIRA and preventing long-term disability
- Exercise and physical therapy — Helps maintain muscle and brain function
- Brain-healthy diet — Foods like leafy greens, fatty fish, berries, and walnuts support brain health
- Good sleep habits — Sleep plays a key role in brain health
- Managing cardiovascular risk factors — Things like blood pressure and cholesterol can influence PIRA progression

Tracking subtle changes in walking, stamina, coordination, and thinking — and sharing them regularly with your neurologist — is also really valuable. Researchers are actively working on treatments that not only calm the immune system but also protect nerves and promote repair. So while PIRA is currently an ongoing concern, the science is moving in a hopeful direction. A conversation with your neurologist about PIRA and whether your current treatment plan addresses it is absolutely worth having.
