Purpose Of Review: In autonomic failure, neurogenic orthostatic hypotension (nOH) and neurogenic supine hypertension (nSH) are interrelated conditions characterized by postural blood pressure (BP) dysregulation. nOH results in a sustained BP drop upon standing, which can lead to symptoms that include lightheadedness, orthostatic dizziness, presyncope, and syncope. nSH is characterized by elevated BP when supine and, although often asymptomatic, may increase long-term cardiovascular and cerebrovascular risk. This article reviews the pathophysiology and clinical characteristics of nOH and nSH, and describes the management of patients with both nOH and nSH.
Recent Findings: Pressor medications required to treat the symptoms of nOH also increase the risk of nSH. Because nOH and nSH are hemodynamically opposed, therapies to treat one condition may exacerbate the other. The management of patients with nOH who also have nSH can be challenging and requires an individualized approach to balance the short- and long-term risks associated with these conditions. Approaches to manage neurogenic BP dysregulation include nonpharmacologic approaches and pharmacologic treatments. A stepwise treatment approach is presented to help guide neurologists in managing patients with both nOH and nSH.

Parkinson's disease (PD) often presents with autonomic dysregulation, leading to blood pressure irregularities such as neurogenic orthostatic hypotension (nOH), neurogenic supine hypertension (nSH), and postprandial hypotension (PPH). Unfortunately, these conditions remain prevalent and receive insufficient attention in scientific discourse. They not only cause complications like syncope, falls, and fractures but also result in long-term damage to vital organs, diminishing patients' quality of life.

Patients with cardiovascular autonomic failure (AF) may suffer from neurogenic supine hypertension (nSH), defined as systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg, after 5 min of rest in the supine position, combined with neurogenic orthostatic hypotension (nOH) in approximately 50% of the cases. nSH may be the manifestation of central or peripheral autonomic lesions. Long-term risks are hypothesized with SH, including renal dysfunction, left ventricular hypertrophy, cerebrovascular disease and cognitive impairment.

Hydrogen sulfide (HS) has been regarded as an important gas transmitter playing vital role in cytoprotective processes and redox signaling. It is very meaningful to monitor and analyze it in biosystem for obtaining important physiological and pathological information. Despite numerous fluorescent probes for cellular HS have been reported in past decades, only a few have capability to detect mitochondrial HS with near-infrared (NIR) emission.

Introduction: Orthostatic hypotension (OH) is a common yet often overlooked condition. Particularly debilitating is neurogenic orthostatic hypotension (nOH) caused by deficient neurotransmission of norepinephrine, which is the primary neurotransmitter released at sympathetic peripheral vascular nerve terminals in response to orthostatic stress.
Areas Covered: In this review, the author summarizes and critiques established and emerging pharmacologic approaches for the management of nOH.
