Abstract:
Inflammatory neuropathies are acquired disorders of peripheral nerves and occasionally of the central nervous system that can affect individuals at any age. The course can be monophasic, relapsing, or progressive. Inflammatory neuropathies are classified as acute or chronic. The acute form reaches a nadir by 4 weeks and the chronic form over 8 weeks or greater. The most common example of an acute inflammatory neuropathy is acute inflammatory demyelinating polyradiculoneuropathy (AIDP), which is part of the Guillain-Barré syndrome (GBS). The most common chronic inflammatory neuropathy is chronic inflammatory demyelinating polyradiculopathy (CIDP). Other chronic inflammatory neuropathies are multifocal motor neuropathy (MMN) and the Lewis-Sumner syndrome. The Fisher syndrome and Bickerstaff brainstem encephalitis occur acutely and have clinical overlap with AIDP.
