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, according to sophisticated brain scans.

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

Alzheimer’s disease may damage the brain in two phases, according to new research published in Nature Neuroscience on Monday.

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.

New research suggests the disease occurs in two phases, including one in which changes happen gradually – and 'quietly.'

Alzheimer's disease may progress in two distinct phases, with the early phase affecting specific brain cells before symptoms appear, and the later phase marked by rapid deterioration.

Alzheimer’s disease is life-threatening and some of the common symptoms don’t appear until the condition has significantly damaged the brain. Neuroscientists are desperately trying to help people prevent the condition,

When you think of Alzheimer's disease, an older person probably comes to mind; however, it can occur in people younger than 50. Our expert explains.

Alzheimer's disease is the most common cause of dementia. Here the Alzheimer's Society explains what Alzheimer's disease is.
