Discussions about the cause and treatment of essential hypertension usually focus on mechanisms such as sodium/volume and the renin-angiotensin system. Less often discussed is hypertension driven by the sympathetic nervous system, i.e., neurogenic hypertension. In this review I discuss the pathophysiology of neurogenic hypertension, the controversy of renal versus central origin, the clinical clues that suggest neurogenic hypertension, and the interventions best suited in its treatment. Neurogenic hypertension is most likely to occur in patients with labile or paroxysmal hypertension, but evidence of increased sympathetic tone also suggests a neurogenic component in hypertension in patients with severe or resistant hypertension, chronic renal disease, comorbidities associated with increased sympathetic tone, and ingestion of drugs that stimulate sympathetic tone. The importance of combined alpha- and beta-blockade in pharmacologic treatment and the status of renal denervation are discussed. Although there is much that is unclear in its pathophysiology, recognition of neurogenic hypertension is of considerable clinical importance in individualizing drug therapy and achieving blood pressure control.
