March 2017

Alzheimer's Disease International (ADI) estimates there will be over 131.5 million people living with dementia by 2050, as well as a shift in burden from the richest to poorest countries. These trends emphasize the need for a greater understanding of dementia from a global perspective.

In this month's Editorial, Carol Brayne and Bruce Miller, the Guest Editors of March's Special Issue on "Dementia across the Lifespan and around the Globe" highlight some of the key papers published in this issue of PLOS Medicine and discuss future directions for dementia research.
