The first episode of our new five-part Dementia Decoded podcast series looks at what Alzheimer's is, how it differs from other forms of Dementia, and whether is it an inevitable part of aging.

Polls show that Americans fear Alzheimer's disease more than any other illness. And little wonder - it's debilitating, fatal, incurable, and currently afflicts hundreds of millions worldwide, a number that's going to continue increasing as the world’s population both grows and grows older. But what is Alzheimer's? How is it different from other forms of Dementia? And is it an inevitable part of aging? This podcast features interviews with leading experts from every aspect of the study of Dementia: academia, health care, public policy, and beyond.
