The nerve fibers are composed of axons, which transmit electrical signals that help neurons communicate with one another. On the other hand, 'nonspecific white matter' changes are usually small blood vessel changes in the brain induced by high blood pressure, high cholesterol, and related chronic medical problems that lead to plaque formation and blood vessel disease throughout the body.
