Neurogenic orthostatic hypotension: pathophysiology, evaluation, and management [PDF]
Journal of Neurology, 2012 Neurogenic orthostatic hypotension is a distinctive and treatable sign of cardiovascular autonomic dysfunction. It is caused by failure of noradrenergic neurotransmission that is associated with a range of primary or secondary autonomic disorders, including pure autonomic failure, Parkinson's disease with autonomic failure, multiple system atrophy as ...

Droxidopa for neurogenic orthostatic hypotension
Expert Opinion on Orphan Drugs, 2015Introduction: Neurogenic orthostatic hypotension is a disabling manifestation of autonomic failure seen in disorders such as multiple system atrophy, pure autonomic failure, Lewy body disease, Parkinson’s disease, autonomic neuropathies and dopamine β-hydroxylase deficiency.Areas covered: Droxidopa is an orally administered norepinephrine prodrug that ...

Insulin‐induced hypotension and neurogenic orthostatic hypotension
Neurology, 1986Insulin-induced hypoglycemia induced a fall in blood pressure (BP) in patients with idiopathic orthostatic hypotension (IOH) and multiple system atrophy (MSA), but not in control subjects. Only in IOH was there a correlation between plasma norepinephrine (NE) levels and maintenance of BP during the test. The hypotension was not affected by pretreatment

Neurogenic Orthostatic Hypotension
New England Journal of Medicine, 2008615 A 65-year-old man reports a 6-month history of dizziness, light-headedness, weakness, and fatigue while upright. He takes no medication and has no personal or family history of neurologic disease. On physical examination, his supine blood pressure is 160/100 mm Hg, with a heart rate of 72 beats per minute; on standing, his blood pressure falls to ...

Neuropharmacologic Distinction of Neurogenic Orthostatic Hypotension Syndromes
Clinical Neuropharmacology, 2006Neurogenic orthostatic hypotension (OH) characterizes pure autonomic failure (PAF), multiple system atrophy (MSA), and Parkinson disease (PD) with autonomic failure. We used neuropharmacologic probes that might distinguish these diseases based on loss of sympathetic noradrenergic nerves in PAF and PD + OH but not in MSA, and related the results to ...

The maintenance of adequate upright BP requires both a baroreceptor-mediated feedback loop and an effective circulating blood volume. Although functional disruptions of these mechanisms are reversible and common, several permanent and often progressive neurologic disorders exist that interfere with necessary reflexes and orthostatic BP control ...

[Medication for Neurogenic Orthostatic Hypotension].
Brain and nerve = Shinkei kenkyu no shinpo, 2023Orthostatic hypotension is a phenomenon characterized by reduction in blood pressure secondary to the inability to adapt to changes in blood volume distribution (pooling of blood in the lower extremities) observed when standing from a seated or supine position. Orthostatic hypotension is classified into neurogenic and non-neurogenic types.

New Developments in the Management of Neurogenic Orthostatic Hypotension
Current Cardiology Reports, 2014Orthostatic hypotension (OH) is defined as a sustained reduction of ≥ 20 mmHg systolic blood pressure or ≥ 10 mmHg diastolic blood pressure upon standing for ≤ 3 min. Orthostatic hypotension is commonly associated with hypertension, and its prevalence is highest in those with uncontrolled hypertension compared to those with controlled hypertension or ...
