What causes neurogenic hypotension?
Background. Neurogenic orthostatic hypotension (nOH) results from impaired vasoconstriction due to dysfunction of the autonomic nervous system and is commonly associated with Parkinson disease (PD), multiple system atrophy (MSA), and pure autonomic failure.
What is orthostatic hypotension Dysautonomic syndrome?
Thus orthostatic hypotension, a drop in blood pressure on standing, will be accompanied by syncope or dizziness, the most striking of the symptoms of dysautonomia. The baroreceptor/cardioaccelerator-pressor reflex is the autonomic mechanism responsible for this aspect of blood pressure control.
