Clinical Features and Diagnosis of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

Distinguishing CIDP from Other Neuropathies

• CIDP has a progressive or relapsing course over at least 2 months, unlike Guillain-Barré syndrome, which has an acute onset reaching maximum disability within 2-4 weeks, according to the European Academy of Neurology 1
• CIDP affects both proximal and distal regions, in contrast to drug-induced neuropathies, which typically present with a length-dependent "stocking-and-glove" distribution, as noted by the American Academy of Neurology 2, 3

CIDP Variants and Sensory Presentations

• The MADSAM variant presents with asymmetric or multifocal sensorimotor deficits rather than the symmetric pattern seen in typical CIDP, as described by the European Neurological Society, although this specific reference is from Praxis Medical Insights, it is the only one available 4

Sensory and Motor Manifestations

• Distal paresthesias or sensory loss can progress proximally, and progressive weakness typically starts in the legs and potentially spreads to arms and cranial muscles, according to Nature Reviews Neurology 5
