Person taking test

The number of people with dementia in the UK is expected to rise to 1.4 million in 2040, Alzheimer’s Society writes.

As it stands, almost a million of us have the condition (982,000).

Still, the condition often goes undiagnosed. A 2018 study found that among older adults with likely dementia, 58.7% were either undiagnosed (39.5%) or unaware of the diagnosis (19.2%).

One in four adults with suspected dementia wait for two years before getting help, the NHS writes, which is a shame as “an accurate and early diagnosis can have many benefits.”

So it’s no wonder Dr Doug Brown, Director of Research and Development at Alzheimer’s Society, was intrigued by a 2015 paper which linked the results of memory and cognition tests to increased dementia risk 18 years before diagnosis.

“This could mean there is a long window of opportunity for treatment in which we could one day halt or slow dementia,” he stated.
