"The results fundamentally alter scientists' understanding of how Alzheimer's harms the brain," researchers say.

Alzheimer's disease might damage the brain in two distinct phases, a new study suggests. An early phase that occurs slowly and silently appears to lay the groundwork for a second, more widely destructive phase of Alzheimer's,

An analysis of the genetic activity of brain cells in individuals who have died with Alzheimer's disease has revealed the condition progresses in two stages; a slow increase in inflammation, followed by a more rapid degeneration.
