According to the CDC, an estimated 6.5 million Americans are living with Alzheimer's Disease, which does not have a cure. However, researchers are hopeful about a new medication that could possibly help slow its progression in certain individuals. Documented side effects for the medication included edema, which is accumulation of fluid in brain tissue and micro-hemorrhages. The FDA recently authorized accelerated approval of the medication. But, it will be a while before it's widely available and covered by insurers. And again, only certain individuals would be eligible for it.
