Using current techniques, Alzheimer's disease, the most frequent cause of dementia, can only be detected once the typical plaques have formed in the brain. At this point, therapy seems no longer possible. However, the first changes caused by Alzheimer's take…

Two proteins central to the pathology of Alzheimer's disease act as prions -- misshapen proteins that spread through tissue like an infection by forcing normal proteins to adopt the same misfolded shape -- according to new research.

A study in mice shows that selectively removing cells that are no longer dividing from the brains of mice with a form of Alzheimer's disease can reduce brain damage and inflammation, and slow the pace of cognitive decline. These findings…

Alzheimer's is dementia, but not all dementias are Alzheimer's (which may explain why so many Alzheimer's drugs have failed in clinical trials). A new study provides a framework for a newly characterized form of dementia called LATE.
