Scientists have uncovered an early brain mechanism that may help explain why people carrying the APOE4 gene face a higher risk of Alzheimer’s disease. For millions of people who carry the APOE4 gene, the strongest known genetic risk factor for Alzheimer’s disease, changes in brain activity may start years before memory problems become noticeable. Researchers [...]

A new study shows that tau helps organize and preserve long-term memories, while abnormal tau may contribute to memory problems in Alzheimer’s disease by disrupting memory formation and recall. New research has revealed that tau, a protein closely linked to Alzheimer’s disease, is also essential for creating long-lasting memories. The findings could point to new [...]
