Scientists have long wondered why some people develop Alzheimer's disease while others have healthy brains throughout their lifetime. Now, new research identifies a molecule that protects brain cells from the stress of aging, which may stave off neurodegenerative diseases. Researchers found that people who experience early cognitive decline appear to have lower levels of a stress-protecting protein in their brains compared with cognitively healthy people. The finding suggests a possible target for diagnosing or preventing Alzheimer's disease and other forms of dementia.
