Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
Introduction
Chronic inflammatory demyelinating polyneuropathy is an immune-mediated polyneuropathy characterized by symmetric weakness of proximal and distal muscles and by progression continuing > 2 months. (See also Overview of Peripheral Nervous System Disorders .) Symptoms of chronic inflammatory demyelinating polyneuropathy (CIDP) resemble those of Guillain-Barré Syndrome (GBS) . However, progression for > 2 months differentiates CIDP from Guillain-Barré syndrome, which is monophasic and self-limited. CIDP develops in 2 to 5% of patients initially diagnosed with Guillain-Barré syndrome. The cause is thought to be autoimmune, resulting in Overview of Demyelinating Disorders .
