While dementia is much more common in older adults, hundreds of thousands of people are diagnosed with young-onset dementia (YOD) each year – and an extensive new study sheds some considerable new light on why.

“This is the largest and most robust study of its kind ever conducted,” says epidemiologist David Llewellyn from the University of Exeter in the UK.
