Our brains hold a hidden factory independent of dietary cholesterol. Behind the blood-brain
barrier they meticulously craft their own using it for a critical purpose: myelin. This fatty
sheath acts like electrical insulation for our nerve fibers ensuring rapid and clear
communication between brain cells. But this finely tuned system can go awry. When cholesterol
levels become imbalanced myelin production suffers. This can lead to a breakdown in
communication impacting memory learning and even movement. In extreme cases it can
contribute to the development of neurodegenerative diseases. By understanding this delicate
balance between brain-made cholesterol and myelin health we can unlock strategies to protect
our cognitive function and overall brain well-being
