Carer's frustration at delay in dementia diagnosis

A leading expert on dementia has called on major industrial nations to step up efforts to beat the disease, amid what he called achingly slow progress.

Dr Dennis Gillings, new world dementia envoy, said a pledge by G8 countries to develop a cure or treatment by 2025 was "impossible" without better incentives for investment.

He also called for faster and cheaper clinical trials for drugs.

Lee Pearse's mother was diagnosed with a special type of dementia seven years ago, when she was 59.

He told BBC Breakfast presenters Charlie Stayt and Sally Nugent how the disease had manifested itself.
