Neurogenic orthostatic hypotension: chasing “the fall” [PDF]

open access: bronzePostgraduate Medical Journal, 2008
Abstract Orthostatic hypotension (OH) is a frequently encountered problem affecting nearly 30% of the population aged more than 60 years. It can result from neurological and non-neurological derangements which compromise the perfusion of the brain in an erect posture. Neurogenic OH is a manifestation of autonomic failure.

Norepinephrine Precursor Therapy in Neurogenic Orthostatic Hypotension [PDF]

open access: bronzeCirculation, 2003
Background— In patients with neurogenic orthostatic hypotension (NOH), the availability of the sympathetic neurotransmitter norepinephrine (NE) in the synaptic cleft is insufficient to maintain blood pressure while in the standing posture.

Norepinephrine reuptake blockade to treat neurogenic orthostatic hypotension [PDF]

open access: hybridClinical Autonomic Research, 2021
<jats:title>Abstract</jats:title><jats:p>GNSS satellite and receiving antennas exhibit group delay variations (GDV), which affect code pseudorange measurements. Like antenna phase center variations, which affect phase measurements, they are frequency-dependent and vary with the direction of the transmitted and received signal.

Characterization of the symptoms of neurogenic orthostatic hypotension and their impact from a survey of patients and caregivers [PDF]

open access: goldBMC Neurology, 2018
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 ...

Management of neurogenic orthostatic hypotension: an update [PDF]

open access: greenThe Lancet Neurology, 2008
Orthostatic hypotension (OH) is common in elderly people and in patients with disorders such as diabetes and Parkinson's disease. Grading of the severity of OH and its effect on the patient's quality of life are important. The symptoms vary with orthostatic stress, and subtle symptoms such as tiredness and cognitive impairment should be recognised ...

Orthostatic hypotension: An overlooked but clinically decisive entity

open access: yesJournal of the Indian Academy of Geriatrics, 2022
Orthostatic hypotension (OH) is defined as a drop of >20 mm Hg of systolic or >10 mm Hg of diastolic blood pressure (BP) within 3 min of standing from lying position. It is a common geriatric syndrome caused by impaired orthostatic response of BP.
