<p>The neuroelectrophysiological manifestations of four clinical typical neurological autoimmune diseases including multiple sclerosis (MS), Guillain-Barré syndrome (GBS), myasthenia gravis (MG), and polymyositis and dermatomyositis were reviewed in this paper. The diagnostic value of evoked potentials for multiple sclerosis, nerve conduction studies (NCS) for Guillain-Barré syndrome, repetitive nerve stimulation (RNS) and single-fiber electromyography (SFEMG) for myasthenia gravis, and needle electromyography for polymyositis and dermatomyositis were respectively discussed. This review will help to have comprehensive understanding on electrophysiological examinations and their clinical significance in the diagnosis of neurological autoimmune diseases.</p><p> </p><p>doi: 10.3969/j.issn.1672-6731.2014.09.004</p>
