Alzheimer’s-related dementia could be prevented by experimental drug, researchers say

An experimental drug has shown promise in preventing Alzheimer’s for people at higher risk of developing the disease.

That’s according to a new study from Washington University School of Medicine in St. Louis, where researchers ran a clinical trial of people with rare genetic mutations that almost "guarantee" future Alzheimer’s development, according to a press release.

The study included 73 people in their 30s, 40s and 50s who have the mutation, which causes an overproduction of amyloid in the brain.
