Lord Cameron has revealed the devastating toll his mother's Alzheimer's disease took, sharing that she once pleaded with his sister, "Will you kill me? You know how to do it."

Mary Cameron, who served as a magistrate for three decades, experienced increasing forgetfulness and disorientation as the disease advanced. Lord Cameron described witnessing a "super bright," strong character gradually fade into a "world of darkness."

During one particularly difficult moment, his mother turned to her daughter, Clare, with the plea to end her life. Lord Cameron recounted his sister's response: "Mum, even if I did know how to kill you, I don't want to go to prison for murdering my mother."

Mrs. Cameron passed away last year at the age of 90, six years after her initial diagnosis. Her struggle has become a driving force behind Lord Cameron's advocacy for improved access to innovative treatments for Alzheimer's.

New drugs capable of slowing the progression of Alzheimer's by a third were licensed in 2024 but have been rejected for routine use on the NHS due to cost-effectiveness concerns. Lord Cameron believes that while Mayor Andy Burnham is committed to tackling the dementia crisis, further pressure must be applied to the NHS. "We are cracking this disease," he stated.

These comments follow a significant boost for dementia carers, with the Mail's "Dementia Carers Together" appeal, in partnership with the Alzheimer's Society and the Mail Force charity, surpassing its initial fundraising target of £100,000 within a week. This success will fund nearly 3,000 courses designed to offer vital emotional and practical support to unpaid dementia carers across the UK. However, further contributions are needed for a comprehensive national rollout.
