An anti-aging drug may help protect the brain before Alzheimer's symptoms begin

A new study suggests the anti-aging drug rapamycin may help protect people genetically predisposed to Alzheimer's disease. Researchers report that four weeks of low-dose rapamycin improved brain blood flow in healthy middle-aged adults carrying the high-risk APOE4 gene variant, with women showing the strongest benefits; because blood-flow decline can occur years before symptoms, the finding raises hopes of preventing or delaying the disease before memory loss begins.
