Neurogenic hypertension in the Guillain-Barré syndrome.

We report a case of Guillain-Barré syndrome associated with hypertension. The hypertension was related to glossopharyngeal and vagal nerve impairment. Plasma noradrenaline concentration (NA) and plasma renin activity (PRA) were elevated. The possible mechanism of the neurogenic hypertension produced by the sino-aortic denervation is discussed.
