TV veteran Alastair Stewart has revealed he has been diagnosed with early onset vascular dementia.

The 71-year-old former ITV News presenter retired from regular broadcasting on GB News earlier this year after nearly five decades on air.

He hosted his final episode of Alastair Stewart And Friends, a discussion programme on GB News, in March.

Stewart left ITV in 2020, where he had presented a range of news and current affairs programmes including the evening news, lunchtime news and News At Ten, after more than 35 years with the broadcaster.

He told GB News programme The Camilla Tominey Show on Sunday: “I mean, the headline story, and it is relatively dramatic, I suppose, is that about six, nine months ago, I began to feel one of my favourite words, a bit discombobulated.

“I wasn’t becoming forgetful but things like doing your shoelaces properly – that’s how I wear these lovely moccasins now – making sure your tie was straight, remembering that the call time for your programme is four o’clock and not five o’clock, not turning up early or late, and stuff like that.

“I then decided at my ripe old age of late 50s, early 60s, that I might have something wrong.”

He added that he went to see his GP and was sent for a scan which revealed he had had a serious of “minor strokes that are called infarct strokes”, and led to a diagnosis of vascular dementia.

According to the NHS, the common condition is caused by reduced blood flow to the brain, which has symptoms including slowness of thought and problems with concentration.

Stewart said that, following the news, he moved to “a contributor contract” at GB News and has appeared as a commentator on major news events such as the King’s Coronation for the channel.

He added: “The thing I have found most difficult to deal with, genuinely, is the impact it’s had on Sally, my wife. We’ve been married for nearly half a century, and, you know, your life partner, your lover, all of those descriptions that are personal and intimate, that person is reduced – I choose my words very carefully – almost to a carer.”

Stewart said his wife, who has worked as a production assistant, and with whom he has four children, had to make sure he was ready before appearing for the interview and that his “tie was done properly”.

He added: “So, if you do think that there’s something wrong with you, go and see the GP, listen to what he or she says.

“But also do remember that the people you work with and the people you live with and share your life with are the most important people in the entire world. And they are there if you’re lucky enough, as I was, to help you.”

Dementia UK’s senior consultant admiral nurse Victoria Lyons said they are “very sorry” to hear of Stewart’s diagnosis and hope support is being provide to him and his family.

She added: “By choosing to speak publicly about his diagnosis, Alastair will raise vital awareness of dementia and we hope that this will encourage others to seek advice if they have concerns for their brain health.”

GB News presenter Gloria De Piero, Tory MP Michael Fabricant and journalist Emma Woolf all sent messages of support.

Former GMTV presenter Fiona Phillips recently said she has been diagnosed with Alzheimer’s, and the family of American actor Bruce Willis have revealed he has frontotemporal dementia.

Phillips, 62, said in July that she hopes her involvement in clinical trials will be a step towards defeating Alzheimer’s, telling the Daily Mirror: “I can’t just lie down and accept it.”

Kate Lee, chief executive of Alzheimer’s Society, said: “We are so sorry to hear that Alastair Stewart has been diagnosed with dementia and our thoughts are with him and his family.”

She added that “speaking so candidly” can help others understand the condition which “devastates lives”.

During his career, Stewart has covered stories such as the Beslan school siege in Russia, the fall of the Berlin Wall in Germany, and various royal weddings.

He was named Presenter of the Year at the Royal Television Society Awards in 2004 and two years later was made an OBE for services to broadcasting and charity.

He started his career in 1976 at ITV’s Southern Television in Southampton, where he served as a general reporter, industrial correspondent, presenter and documentary-maker.

In 1980 he joined ITN as industrial correspondent and a decade later became Washington correspondent.

He went on to anchor ITN’s coverage of the first Gulf War and became the first UK TV reporter to broadcast live from the liberated Kuwait City.

Stewart has also chaired debates with political figures, including Gordon Brown, David Cameron and Nick Clegg ahead of the 2010 General Election for ITV, and for GB News when Rishi Sunak and Liz Truss were bidding for the Conservative Party leadership.
