Overview
- Campbell, whose wife announced his death Wednesday on Instagram, died peacefully at the Northern Ireland Hospice after ten days of care with family and friends at his side.
- He was diagnosed with motor neurone disease in February 2023 after right‑foot problems in 2022 that led to repeated stumbles during a Dublin Fringe performance.
- He joined a drug trial in late 2024 and told the BBC in January 2026 that feeling had returned to his feet and he could wiggle his toes.
- He turned his illness into art with collaborator Oisín Kearney, making a short film called So You're Going to Die and a one‑man show titled My Right Foot.
- MND has no cure and can progress fast by weakening muscles that control movement, speech and breathing, and the NHS says early signs like twitches or foot drop should be checked by a GP.
