Does myelination occur throughout life? Answering the question of lifelong brain health

Research has shown that myelination, the process of forming a protective sheath around nerve fibers, continues well beyond adolescence, even into a person's 30s and beyond. This continued activity supports neural circuit plasticity throughout the lifespan, meaning the answer to the question, "Does myelination occur throughout life?" is yes, to a significant extent.

How Does Myelination Change with Age?

Brain white matter volume can decrease by nearly 30% between ages 20 and 80, a phenomenon linked to significant alterations in the protective myelin sheath. This process involves a complex interplay of degradation and compromised repair, fundamentally changing how myelination changes with age and impacting brain function.

Does Myelin Increase or Decrease with Age? An In-depth Look

While the brain continues to produce new myelin throughout life, the overall amount of **myelin decreases with age** due to progressive degeneration and less efficient repair mechanisms. Myelination is a lifelong process that peaks in mid-life before entering a phase of gradual decline. This demyelination is a key factor in age-related cognitive and motor function decline.

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.
