TV repeats and classic films can help people with Alzheimer’s cope with Christmas, the NHS dementia tsar has said.

Prof Alistair Burns said singing along to White Christmas, playing favourite family games or re-watching old movies like It’s a Wonderful Life can stimulate “emotional memories” and feelings of connection.

The NHS already recommends “reminiscence therapies,” to help those with dementia, which typically affects short-term recall far more than long-held memories.

Health experts say that rekindling nostalgia, via old films, photographs, and family traditions can help to keep the brains active, as well as boosting confidence.

Prof Alistair Burns, national clinical director for dementia, said such activities could help to ensure those with the condition enjoyed Christmas, instead of being overwhelmed by it.

He said: “People with dementia might find it hard to follow convoluted conversations amid the chaos and noise of Christmas and can end up feeling excluded.

“Gathering the family round to watch a much-loved classic film, thumb through an old photo album, play a family game or even sing along to a favourite carol can bring people together and help everybody feel part of the fun.”

Experts say that emotional memories remain lodged longer than specific details, meaning that films first watched long ago can help stimulate old memories, and feelings of contentment.
