Researchers are investigating the effects of Alzheimer's disease on the brain, with some studies focusing on why the disease tends to damage certain areas, such as the memory hub, first. There is also exploration into the characteristics of "super-ager" brains, which may hold clues to preventing or slowing the disease. The search for a better understanding of Alzheimer's is ongoing, with various institutions and companies, including pharmaceutical firms, working on potential breakthroughs.
