What Causes CIDP?
The dominant theory holds that the body’s immune system sees the fatty protective covering of the nerves (myelin sheath) as a foreign entity and begins to attack it. The fatty protective layer is critical for proper functioning of the peripheral nervous system and the propagation of nerve impulses. The fatty protective layer (myelin sheath) allows electrical signals to move along the nerve axon. When the fatty protective layer is destroyed or damaged, electrical signals are disrupted or lost, resulting in pain and impaired sensory and or motor functions.
