Objective: To recognize different forms of Guillain-Barre syndrome (GBS) in northern China.
Methods: Twenty-one cases were found in two counties of Beijing suburb from January 1993, to December, 1994. Multiple electrophysiological studies including magnetic motor evoked potential, F-wave, motor and sensory conduction velocity, blink reflex and needle electromyography were conducted on nineteen cases of them. Twelve cases accepted electrophysiological follow-up study.
Results: Altogether 17 cases showed demyelination features in multiple electrodiagnosis. Ten cases of them were accompanied by different extent of axonal lesion. Only one case showed main or primary axonal lesion.
Conclusions: Demyelination is the main type of pathophysiological lesion of GBS in Beijing suburb. Different extent of axonal lesion can appear in some cases, but primary and main axonal type is rare in this area.
