Memory-restoring compound could destroy Alzheimer's forever

Aging rats have had their memory loss reversed, thanks to a compound that helps them form new memories again. The compound could be a breakthrough treatment for Alzheimer's. Essential to the creation and maintenance of memories is neurogenesis, in which new neurons are created and then wired into the brain's circuitry. This process occurs in the dentate gyrus, a key sector of the brain's memory hub in the hippocampus. Even in healthy brains, this is a difficult process, with only about 10% of these neurons surviving long enough to become a useful part of memory production. Alzheimer's disease, which is characterized by uncontrolled cell death, the survival rate drops to close to zero.
