Veteran journalist and former Channel 4 News anchor Jon Snow says he has been diagnosed with Alzheimer’s disease, the most common form of dementia. Multiple outlets report that Snow, 78, discusses his diagnosis in a new Channel 4 documentary, “Jon Snow: A Last Big Story,” which is due to air on Saturday 20 June. Snow says he was told he had Alzheimer’s around four years ago and that he initially wanted to keep the condition private due to stigma. In interviews and statements referenced by the reports, he explains how his life has changed while continuing to focus on work and investigation. The Alzheimer’s Society is cited as commenting on his decision to go public, describing it as significant for raising awareness and encouraging faster access to diagnosis and support. Snow stepped down from Channel 4 News in 2021 after more than three decades with the broadcaster. In the documentary, he also addresses the reality of living with Alzheimer’s, including managing day-to-day impacts and the need for help for people and families affected by dementia.
