Dual cancer drugs restore memory and rewire brain cells in Alzheimer’s mouse models

Researchers identified a combination of two existing cancer drugs, letrozole and irinotecan, that reversed Alzheimer’s disease-related changes in brain cell networks and improved memory in mouse models. The study supports a multi-cell-type, network-correcting strategy as a promising path for future Alzheimer’s treatments.
