Legendary journalist Jon Snow opens up about his Alzheimer's diagnosis and how he's navigating life with the condition.

Jon Snowthe 78-year-old former anchor of Channel 4 Newsrevealed his Alzheimer’s diagnosis and confirmed that his documentary Jon Snow: A Last Big Story will air on Channel 4 at 8 pm on June 20 after premiering at the Sheffield documentary festival.
The broadcaster’s disclosure, made as he prepares a return to screens in the UK, centers on living with dementia while pursuing one final investigation.
This update matters because Snow’s announcement adds a high-profile voice to a public health issue and aligns with calls for earlier diagnosis and better support for people with dementia.
The documentary offers a rare, first-hand account of managing a progressive brain disorder while continuing professional work, and it has already prompted statements from national leaders and advocacy groups. Last update: 7 June 2026.
Diagnosis, stigma and the decision to go public
Snow said he initially avoided disclosure because of stigma around mental health and cognitive conditions, noting, “At the beginning I wanted to hide it, there’s so much prejudice.” His wife, epidemiologist Dr Precious Lungadescribed the diagnostic pathway: Snow first scored 29 out of 30 on a mini-mental state exam, which appeared near-normal, but a subsequent brain scan led to confirmation of Alzheimer’s. Snow has been privately managing the condition in 2026 and has taken part in a clinical trial, adding that he sometimes questions the diagnosis, saying, “I don’t feel disabled in any way.”
Support arrived quickly after the announcement. Prime Minister Sir Keir Starmer called Snow “a true giant in journalism” and praised his decision to speak publicly. Alzheimer’s Society chief executive Michelle Dyson commended the move as an act of courage, underscoring the need for faster, fairer access to diagnosis and post-diagnostic help for families. Channel 4’s head of news Louisa Compton said it was a privilege to document Snow’s final investigation.
The film: from Sheffield premiere to Channel 4 broadcast
The documentary, produced in collaboration with dementia advocates, premieres at the Sheffield documentary festival before its Channel 4 broadcast on June 20. In Jon Snow: A Last Big Storythe veteran reporter travels to Zambia to examine the impact on a community affected by a mining-related environmental disaster, interweaving his reporting with an honest account of memory tests, medical consultations and family conversations after diagnosis. The film positions Snow’s personal experience alongside his professional craft, aiming to demystify day-to-day life with Alzheimer’s.
Channel 4 scheduled the UK transmission at 8 pm to reach a wide audience, reflecting sustained public interest in Snow’s career and his new role in awareness-raising. Dr Lunga said the couple have adapted to practical changes while maintaining purpose, noting, “Life doesn’t end with an Alzheimer’s diagnosis, but it changes dramatically,” and adding that people can remain valuable members of society with the right support. The broadcaster’s team framed the film as both an investigation and a public health conversation.
Career milestones and context for a late return
Snow’s return to screens follows his retirement from the Channel 4 anchor chair in 2026 after more than three decades in the studio and on the road. His reporting portfolio includes the fall of the Berlin Wallthe release of Nelson Mandelaassignments in Somalia and Vietnam, and a stint as ITN’s Washington correspondent during the Reagan presidency. He has received the Bafta’s Richard Dimbleby Award for best factual contribution to television (2005), the Bafta Fellowship (2015), and 10 Royal Television Society awards, including six as presenter of the year.
The documentary’s investigative thread in Zambia echoes Snow’s long-standing fieldwork approach, pairing on-the-ground interviews with scrutiny of environmental and public health consequences. Those familiar with his broadcasting style will recognize the focus on accountability and lived experience, while the personal narrative captures adjustments after diagnosis—medical monitoring, memory exercises, and discussions about independence—without portraying Alzheimer’s solely through decline. The combination of legacy journalism and a candid medical journey gives the broadcast added public interest.
Advocates welcomed the timing of Snow’s disclosure and film, saying visibility can reduce stigma and encourage earlier contact with memory services. Dyson emphasized that Alzheimer’s is often not treated with the same urgency as other major conditions and urged improved pathways from initial screening to specialist assessment. As the June 20 broadcast approaches, Channel 4 and the production team indicated that the film aims to inform families about what practical support can look like, while Snow’s own remarks reflect a resolve to keep working: “There’s still more to do.”
