Memories Lost in Alzheimer’s Disease: Potentially Retrievable? (NHS Choices / Nature)

Summary

Research on transgenic mice suggests that memories are not destroyed irretrievably by Alzheimer’s Disease; there appears to be problems recalling these lost memories. Lost memories may be retrievable, under experimental conditions, by exposing “Engram Cells” with bright blue light (in the mouse model of the disease at least).

Note: The researchers caution readers that their techniques are not suitable for humans currently, and that Alzheimer’s Disease in humans may work in a different way.
