More than 5 million Americans suffer from Alzheimer’s disease, a progressive, incurable condition that robs them of their memory and often changes their very personality.

A new documentary airing on PBS at 10 p.m. Eastern time on Jan. 25 examines the disease and what will be needed to confront it.

Alzheimer’s: Every Minute Counts, produced by Twin Cities PBS (the parent of Next Avenue), features interviews with doctors, researchers and caregivers. The focus is on the urgent need for more research, especially as the large boomer generation ages.
