Jon Snow has revealed that he has been privately living with Alzheimer’s disease for the past four years, in what may become one of the most moving and personal stories of his remarkable life.
The former Channel 4 News presenter, now 78, has spent decades reporting on some of the biggest events in modern history — from revolutions and wars to political earthquakes and global crises. But today, the story is painfully closer to home.
At his thatched cottage on the North Wessex Downs, where he lives with his wife Dr Precious Lunga, the once-commanding broadcaster still appears unmistakably himself. Tall, warmly dressed and full of charm, he can still greet visitors with the familiar voice that millions once heard on the evening news.
But behind the warmth, there are moments that reveal the cruel reality of his illness.
A longtime friend visiting his home noticed that Jon asked whether she had been there before, despite the fact she had visited many times over more than 40 years of friendship. It was a small but heartbreaking sign that the disease had begun changing the man so many people knew.
Jon has spent his life making strangers feel at ease, and friends say his good manners can sometimes mask the moments when memory fails him. But now, after years of quiet struggle, he has chosen to speak publicly about his diagnosis for the first time.
There was no single dramatic moment when everything became clear. Instead, his family noticed a gradual pattern of memory lapses, confusion and difficulty processing things.
After more than three decades at Channel 4 News, Jon retired in December 2021 at the age of 74. His decline appeared to begin soon afterwards. Without the daily pressure and stimulation of the newsroom, he became depressed and lost much of his appetite for life.
His wife Precious recalled making his favourite meals, including prawn linguine and scrambled eggs, only to discover he had quietly thrown them away when he thought she was not looking.
Friends tried to help, inviting him to lunch, encouraging him to paint, write and play piano. But Jon would often feel forgotten, even when those closest to him had been calling and checking in.
For a time, Precious was unsure whether his changes were caused by depression or something deeper. Then, ten months after his final bulletin, Jon woke up one morning and told her he was late for work. When she gently reminded him that he had retired, he looked devastated.
As a neuroscientist and epidemiologist, Precious knew that early diagnosis could make a difference. Although there is currently no cure for Alzheimer’s, new treatments and clinical trials may help slow memory loss and mental decline in some patients. 
At first, Jon resisted seeing a doctor, insisting nothing was wrong. But the strain on Precious became intense, and she began experiencing chest pains and panic attacks while trying to cover for him.
In early 2023, she persuaded him to see a specialist. He performed strongly in an initial memory test, scoring 29 out of 30, but a later brain scan confirmed the diagnosis.
The news was devastating, especially because Jon had watched Alzheimer’s affect his own mother, Joan, who died in her 80s after living with the illness for more than a decade. 
After his diagnosis, Jon joined a clinical trial in 2024, with Precious also taking part as his partner. She said discussing the condition with medical teams helped both of them understand what was happening inside his brain.
The couple had once hoped retirement would bring travel, new adventures and more time together as parents to their young son, who was born via surrogacy in 2021. Jon had previously expressed regret over being an absent father to his older daughters, Leila and Freya, while covering wars and revolutions around the world.
This time, he had hoped things would be different.
Although their son is only five, Precious says he already understands that something is happening to his father. He plays piano and paints with Jon, rides bikes with him, and gently tells him to rest when he becomes tired or less coherent.
Jon now has good days and bad days. He remains warm and friendly, but conversations can become repetitive and limited. Some days he is more lucid; on others, another part of the old Jon seems to slip further away.
When asked about his diagnosis, Jon said he did not feel disabled and sometimes doubted whether he really had the illness. At moments, he tries to make light of it, joking about whether friends think he is “bonkers.”
But Precious gently explains that there are mornings when he wakes up anxious because he knows something is wrong in his brain.
Despite everything, Jon’s instinct as a journalist has not disappeared.
He says that if he does not speak out about Alzheimer’s, then who will? His concern now is not only for himself, but for others living without diagnosis or support.
In England, more than a third of people with dementia are believed to be undiagnosed, and dementia research continues to lag behind other major illnesses.
After discussing how best to raise awareness, Jon and Precious decided to make a documentary. At first, the film was intended to focus on life with Alzheimer’s. But during a family trip to Zimbabwe, where Precious grew up, the project took an unexpected turn.
Jon learned about a toxic water contamination disaster in neighbouring Zambia, after a dam linked to a Chinese-owned copper mine collapsed and released millions of litres of acidic waste into local rivers and land.
The film crew decided to follow Jon as he investigated the spill, filming both for the documentary and for Channel 4 News. It would become his last major story.
Precious said Jon “lit up” when he began reporting again, briefly returning to the energy and purpose that had defined him for so many years.
The resulting film, Jon Snow: A Last Big Story, shows that even as Alzheimer’s affects his memory, the journalistic part of his brain remains alive. He still asks sharp questions, shows compassion for victims and gives voice to people who might otherwise be ignored.
For Precious, watching the film was deeply emotional. She said it restored Jon’s confidence and allowed him to feel useful again.
Back home, his piano playing has reportedly improved, and his life is now filled with music, painting, family and quieter moments.
Jon Snow spent decades telling the world’s biggest stories. Now, with courage and vulnerability, he is telling his own.
Jon Snow: A Last Big Story will air and stream on Channel 4 at 8pm on Saturday, June 20.
