Due to the presence of the insulating myelin sheath at internodes and voltage-gated sodium channels at nodes, the action potential in myelinated nerve fibers jumps from one node to the next.

New research reveals that Alzheimer's disease may impair nerve function not by reducing myelin, but by altering the proteins ...

Myelin sheath, a sleeve that protects a part of your nerve cells, and how it's related to multiple sclerosis. Read to learn more about its functions and how to protect it from damage.

The disruption of axons—the thread-like part of nerve cells that transmits electrical signals—is associated with Alzheimer's ...

Not all multiple sclerosis-like diseases are alike Date: May 19, 2020 Source: Tohoku University Summary: Scientists say some myelin-damaging disorders have a distinctive pathology that groups them ...

Barbara Bendlin University of Wisonsin; Posted: 27 Aug 2021 There have been several hints over the years that myelin and AD pathology are related. Braak and Braak made an early and key observation ...

He adds that having APOE4 isn’t known to affect myelin levels in adults without Alzheimer’s pathology, and to his knowledge, nobody has investigated that potential. Therefore, the findings of reduced ...

“If we learn how the proteins that make up the myelin sheath are affected in the diseased state compared to a non-diseased state, we might be able to figure out what’s going on when the disease ...

Brain injuries can also cause damage to myelin. Finding a way to help the sheath to repair itself could open the door to game-changing treatments for these conditions.

Now, researchers from the University of California San Francisco have identified an over-the-counter antihistamine called clemastine that can reverse damage to the myelin sheath and, what’s more ...
