title: Headache and Pain in Guillain-Barré Syndrome.
abstract: While moderate and severe back or extremity pain is frequent in Guillain-Barré syndrome (GBS), headache appears to be uncommon. Most of the reports of headache in GBS place it in the context of the posterior reversible encephalopathy syndrome (PRES) which is increasingly recognized as a likely dysautonomia-related GBS complication. There are also a few reports of headache in the setting of increased CSF pressure and papilledema and in association with the Miller Fisher GBS variant. In comparison, back and extremity pain is highly prevalent. Aching muscle pain and neuropathic pain are the two most common of several pain types. Pain may be a heralding feature and has been described in patients as long as 2 years after disease onset. Pain management is a major axis of treatment in GBS. Gabapentin is a reasonable first-line choice, and opioid medications can be added for more severe pain but there are few clinical trials to inform specific recommendations. While the understanding of pain pathophysiology in GBS is incomplete, its prevalence and clinical impact are increasingly recognized and studied. Pain should be considered a cardinal manifestation of GBS along with acute, mostly symmetric weakness and diminished reflexes.
