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.

How Compass is developedGive feedback

Symptoms and clinical language

Respiratory onset

Describes the less common pattern where breathing changes are the first symptom.

What it means

Breathlessness, disturbed sleep or morning headaches come before noticeable weakness elsewhere. It is less common, and it means breathing support tends to be discussed sooner after diagnosis.

Why you might hear it

  • It explains why breathing tests may have come very early.
  • It is used in research to group people by starting point.

About this explanation

These are plain explanations of words you may come across, not advice about your own situation. Where a word matters to a decision, the question pages go into it properly, and your own team is the place to take it.
