Overview
- Channel 4 broadcast Jon Snow: A Last Big Story on Saturday, June 20, 2026, which publicly confirmed Snow’s Alzheimer’s diagnosis from 2023 and included footage of a clinical memory test where his score fell from 29 out of 30 to 21.
- The programme follows Snow as he continues working on a journalistic investigation into a Zambian mining disaster, demonstrating that he remains professionally active while documenting moments when his memory and focus lapse.
- Dr Precious Lunga, Snow’s wife and a Cambridge‑trained neuroscientist, appears throughout the film as both carer and clinical expert and says the couple faced dismissive reactions she attributes to fear and ignorance about dementia.
- The Alzheimer’s Society, which helped on the film, called Snow’s openness ‘‘a real act of courage’’ and said the documentary has driven public interest in diagnosis, support and potential trial participation.
- The documentary underlines that Alzheimer’s symptoms can fluctuate and progress gradually, and advocates say high‑profile disclosures like Snow’s could reduce stigma, speed up diagnosis pathways, and increase recruitment for research trials.
