The new drug is based on the idea that a build-up of amyloid in the brain leads to the disease. But that hypothesis has been under scrutiny lately.
Knowing what cells are more vulnerable could some day help researchers know why these cells are more vulnerable than others.
We now have the technology to identify people who are on a fast track to developing dementia.
After the failure of multiple drug trials the outlook for an Alzheimer's drug is bleak. This shouldn't be a surprise. We don't know the cause or even how to diagnose the disease.
Not all drug development needs to start from scratch. Sometimes researchers discover that a drug developed for one disease can be used for another. Here a cancer drug may show promise for dementia.
Many pieces leading to Alzheimer's disease have been identified. To put the pieces together, one scholar argues that the government should launch a Manhattan Project-scale effort to find a cure.
