A woman whose DNA suggested she’d develop early-onset dementia staved off cognitive decline for decades.

A hormone treatment contaminated with amyloid-β given to mice caused the protein’s accumulation in their brains, suggesting the same could have occurred in humans given the therapy.

A new study reports that immune memory may contribute to neurodegenerative diseases.

The findings suggest that faster synthesis, rather than decreased clearance, causes the protein to build up in neurons.

The test uses levels of plasma amyloid-β to estimate the buildup of protein plaques in the brain.

The once fringe idea is gaining traction among the scientific community.

In a mouse model, researchers mitigated three Alzheimer’s disease–associated symptoms by stimulating gamma waves with light.

Examining the brains of seven patients who died of the prion disease called Creutzfeldt–Jakob, researchers find signs of Alzheimer’s pathology. 

Aggregate-forming amyloid β proteins are replenished more slowly with age, and this may contribute to a person's risk of developing Alzheimer’s disease.
