Do we lose myelin as we age? The Facts on Age-Related Myelin Decline

According to imaging studies, the human brain’s white matter volume typically peaks around age 30 and begins to decline after 50. A key factor in this process is the degeneration of myelin, the fatty protective sheath around nerve fibers. But the full picture of why we lose myelin as we age and how it affects us is more complex than simple deterioration.
