Myelinopathies

Myelinopathies ( or or "demyelinating polyneuropathie")b are a subset of polyneuropathies in which there is a loss of myelin (or of the Schwann cells that make and contain it). This demyelination slows down or completely blocks the conduction of action potentials through the axon of the nerve cell. The most common cause is acute inflammatory demyelinating polyneuropathy (AIDP, the most common form of Guillain–Barré syndrome), though other causes include chronic inflammatory demyelinating polyneuropathy (CIDP), genetic metabolic disorders (e.g., leukodystrophy), and toxins.
