Overview
From WUSTL NeuromuscularDiagnostic: May be only positive diagnostic test This is especially helpful in patients whose neuropathy would otherwise be labeled as idiopathic. Provides independent support for a diagnosis of an immune-mediated sensory-motor or sensory polyneuropathy. The neuropathy may be either demyelinating or axonal. Suggests treatment possibilities when neuropathy is disabling Prognostic: Suggests that the polyneuropathy will most often be slowly progressive over a period of years. Treatment: Indicates directions for treatment in patients with disabling polyneuropathy Some immunomodulating treatments,
