Great question! PIRA (Progression Independent of Relapse Activity) is tricky because it's often silent and slow — so slow that many people mistake it for just aging or having a rough day.
Some gradual changes to watch for include:
- Increased difficulty walking
- Reduced stamina
- Worsening coordination
- More brain fog or trouble thinking
These shifts can sneak up on you over time, which is why tracking your symptoms regularly and sharing them with your neurologist is so important. Your neurologist can also use specific tools to measure PIRA, including:
- Expanded Disability Status Scale (EDSS) — checks muscle function, balance, coordination, memory, and more
- Timed 25-Foot Walk — measures how long it takes to walk a short course
- 9-Hole Peg Test — times how quickly you can place and remove pegs from a board
If results worsen and stay that way for at least six months, that's generally considered evidence of MS progression.
Since you know your body best, keeping a symptom journal and bringing it to appointments can make a real difference in catching PIRA early.
