For the first time since 1984, Alzheimer's has a new definition.

In four articles published online in Alzheimer's & Dementia, a journal of the Alzheimer's Association, researchers explain that the disease no longer begins with dementia.  Instead, the new definition explains Alzheimer's as a continuum, a degenerative process that may begin years before any concrete symptoms surface.

We sit down with Carey Goldberg, co-host of WBUR's CommonHealth blog to learn more about the disease's new definition, what it might mean for clinical trials and hopefully, a future cure for the debilitating disease.
