Cancer Drugs Reversing Alzheimer's Brain Changes in Mice Show Promise
US researchers used computational analysis to identify two FDA-approved cancer drugs, letrozole and irinotecan, that counteract Alzheimer’s-related gene-expression changes. In mouse models, when used together they reduced tau protein clumps and improved learning and memory, suggesting potential for repurposing and faster clinical testing, though safety in humans and side effects must be evaluated before any trials for Alzheimer's.
