**Brain Cells Once Thought Protective May Actually Drive Cognitive Decline With Age**
By University of Edinburgh - Published on 30 August 2026
Age-related oligodendrocyte dysfunction may contribute to cognitive decline by disrupting myelin and large nerve fibers. Myelin is essential for fast communication in the brain, forming a protective coating around nerve fibers so electrical signals can travel efficiently. But the cells that produce this insulation, called oligodendrocytes, may become dysfunctional with age and actively contribute to [...]
