In December 2019 the BBC Shared Data Unit reported some parts of the UK had seen the number of people diagnosed with dementia more than double in five years, according to analysis of NHS data.
A drive to increase diagnosis rates and an ageing population were behind the increase, experts said.
Charities said dementia care provision must improve, calling it a "ridiculous lottery", and "very hit or miss".
NHS England said it was a priority to diagnose dementia earlier so people could receive correct treatment.
