Compass is still being developed and is effectively in beta. Some content and features may be incomplete, change, or not work as expected.

Content is anchored to trusted sources where available, but Compass has not yet been clinically reviewed. It provides general information rather than medical advice.

Feedback helps us identify gaps, errors, usability problems and opportunities to improve Compass over time.

Treatments and research

Disease-modifying treatment

A treatment aimed at changing the course of the condition itself, rather than easing a symptom.

What it means

A distinction worth holding onto while reading. Symptom treatments can make a real difference to daily life without touching the underlying process; disease-modifying treatments aim at the process. Both matter, and they are answering different questions.

Why you might hear it

  • It is how approved ALS/MND medicines are usually categorised.
  • Research headlines often blur the two.
