This poster is linked to our new leaflet in 2026 ‘What causes ME/CFS?’
This is a three stage disease causing hypothesis – based on three types of factors: those that make someone vulnerable (predisposing), those that trigger it (precipitating), and those that keep it going (perpetuating).
The poster covers key facts on what we already know about these three aspects of causation and the many uncertainties that still exist.
Please read the full leaflet for more information:
