A protein created by a gene that causes Alzheimer’s disease prevents the brain from ridding itself of amyloid beta, the main culprit in the plaques and tangles that are hallmarks of the disease.

People with Alzheimer’s disease have higher concentrations of a particular protein in their spinal fluid than people without the disease, recent research suggests.

Could cinnamon really help fight Alzheimer's disease?

Elderly adults who live in institutions like nursing homes are more likely to experience a syndrome known as “sundowning”—and now researchers have clues as to why.

The triggers for some diseases are never discovered. But often times when they are it offers substantial aid toward finding ways to prevent and treat such diseases.

A naturally occurring brain protein could lead to better treatments for Alzheimer's disease. Scientists have discovered a "molecular chaperone" - a type of protein that responds to disease - and its ability to kill toxic Alzheimer's tangles in the brain.

Much like advanced electronic devices with large systems of circuits and wires, our brain is a complicated machine. But unlike programming a remote control, the brain can do work itself -- shaping and refining memories unassisted.

Coffee may offer a protective benefit against Alzheimer’s disease that other caffeinated drinks don’t—and now researchers are closer to figuring out why.

Progressive supranuclear palsy is a rare and devastating disease with no known treatments. New genetic clues could provide new insights into  neurodegenerative therapies.

Researchers at UCLA have discovered a brain-scan technique that could help detect dementia in adults with Down syndrome. The researchers created a chemical marker, known as FDDNP.
