Jon Snow’s wife Dr Precious Lunga said she felt “anger” at people “writing off” her husband after he was diagnosed with Alzheimer's disease. The former Channel 4 news presenter, 78, and the epidemiologist, 51, explore his diagnosis in a new Channel 4 documentary, Jon Snow: A Last Big Story. The programme shows Snow being told he has the form of dementia following a test. In one scene, Dr Lunga opens up about how she feels Snow’s health has changed. She added: “When we received a diagnosis, people were writing Jon off, and that's when I realised how stigmatised Alzheimer's is, and it made me so angry actually. “This is a progressive disease, but you can have Alzheimer's and still will be a valuable member of society to contribute.”

Dr Lunga, who is a neuroscientist, said that Jon suffered with depression after retiring as a journalist in 2021, which can increase the risk of dementia.

Jon Snow's wife has revealed that she 'burst into tears' when the former Channel 4 News presenter was diagnosed with dementia, and vowed that 'it is not the end' for her husband
