PURPOSE: Patients suffering from cardiovascular autonomic failure often develop neurogenic supine hypertension (nSH), i.e., high blood pressure (BP) in the supine position, which falls in the upright position owing to impaired autonomic regulation. A committee was formed to reach consensus among experts on the definition and diagnosis of nSH in the context of cardiovascular autonomic failure. METHODS: As a first and preparatory step, a systematic search of PubMed-indexed literature on nSH up to January 2017 was performed...

PURPOSE: To review the currently available literature on clinical autonomic tests of sudomotor function. METHODS: We searched PubMED/MEDLINE for articles on technical principles and clinical applications of sudomotor tests with a focus on their drawbacks and perspectives in order to provide a narrative review. RESULTS: The quantitative sudomotor axon reflex sweat test (QSART) is the most widely used test of sudomotor function. The technique captures pathology with low intra- and inter-subject variability but is limited by technical demands...

Catechols are a class of compounds that contain adjacent hydroxyl groups on a benzene ring. Endogenous catechols in human plasma include the catecholamines norepinephrine, epinephrine (adrenaline), and dopamine; the catecholamine precursor DOPA, 3,4-dihydroxyphenylglycol (DHPG), which is the main neuronal metabolite of norepinephrine; and 3,4-dihydroxyphenylacetic acid (DOPAC), which is the main neuronal metabolite of dopamine. In the diagnostic evaluation of patients with known or suspected dysautonomias, measurement of plasma catechols is rarely diagnostic but often is informative...

PURPOSE: Since manned missions to the Moon and Mars are planned, we conducted active standing tests with lunar, Martian, terrestrial, and 1.8 loads of inertial resistance (+Gz ) modeled through defined parabolic flight maneuvers. We hypothesized that the cardiovascular response to active standing is proportional to the +Gz load. METHODS: During partial-+Gz parabolic flights, 14 healthy test subjects performed active stand-up maneuvers under 1 +Gz , lunar (0.16 +Gz ), Martian (0...

The production of emotional tears appears to be uniquely present in Homo sapiens. Despite the ubiquity of this human behavior, research is only just beginning to uncover the neurobiologic underpinnings of human emotional crying. In this article, we review the current state of the literature investigating the neurobiologic aspects of this uniquely human behavior, including the neuroanatomical, neurochemical, and psychophysiologic findings. To set the context for this review, we first provide a brief overview of the evolutionary background and functions of tearful crying...

OBJECTIVE: The current study aimed to investigate autonomic dysfunction in Guillain-Barré syndrome (GBS) patients and describe the results of computational heart rate variability (HRV)/baroreflex sensitivity (BRS) and autonomic challenge tests. METHODS: GBS patients were consecutively recruited and the results were compared to age- and gender-matched healthy controls. A series of autonomic function tests including computation-dependent tests (power spectrum analysis of HRV and BRS at rest) and challenge maneuvers (deep breathing, eyeball compression, active standing, the Valsalva maneuver, sustained handgrip, and the cold pressor test) were performed...

The autonomic nervous system (ANS) is the main homeostatic regulatory system of the body. However, this widely distributed neural network can be easily affected by cancer and by the adverse events induced by cancer treatments. In this review, we have classified the ANS complications of cancer into two categories. The first includes direct cancer-related complications, such as primary ANS tumors (pheochromocytoma, paraganglioma or neuroblastoma), as well as autonomic manifestations induced by non-primary ANS tumors (primary brain tumors and metastases)...

REVIEW

Ascent to high-altitude elicits compensatory physiological adaptations in order to improve oxygenation throughout the body. The brain is particularly vulnerable to the hypoxemia of terrestrial altitude exposure. Herein we review the ventilatory and cerebrovascular changes at altitude and how they are both implicated in the maintenance of oxygen delivery to the brain. Further, the interdependence of ventilation and cerebral blood flow at altitude is discussed. Following the acute hypoxic ventilatory response, acclimatization leads to progressive increases in ventilation, and a partial mitigation of hypoxemia...

Gastrointestinal symptoms are among the most common complaints in patients with postural tachycardia syndrome (POTS). In some cases, they dominate the clinical presentation and cause substantial disabilities, including significant weight loss and malnutrition, that require the use of invasive treatment to support caloric intake. Multiple cross-sectional studies have reported a high prevalence of gastrointestinal symptoms in POTS patients with connective tissue diseases, such as Ehlers-Danlos, hypermobile type, and in patients with evidence of autonomic neuropathy...

REVIEW
Marion Griton, Jan Pieter Konsman
Although the immune and nervous systems have long been considered independent biological systems, they turn out to mingle and interact extensively. The present review summarizes recent insights into the neural pathways activated by and involved in infection-induced inflammation and discusses potential clinical applications. The simplest activation concerns a reflex action within C-fibers leading to neurogenic inflammation. Low concentrations of pro-inflammatory cytokines or bacterial fragments may also act on these afferent nerve fibers to signal the central nervous system and bring about early fever, hyperalgesia and sickness behavior...

REVIEW
Alejandra Gonzalez-Duarte
PURPOSE: Hereditary transthyretin amyloidosis (hATTR amyloidosis) is a progressive disease primarily characterized by adult-onset sensory, motor, and autonomic neuropathy. In this article, we discuss the pathophysiology and principal findings of autonomic neuropathy in hATTR amyloidosis, the most common methods of assessment and progression, and its relation as a predictive risk factor or a measure of progression in the natural history of the disease. METHODS: A literature search was performed using the terms "autonomic neuropathy," "dysautonomia," and "autonomic symptoms" in patients with hereditary transthyretin amyloidosis and familial amyloid polyneuropathy...

OBJECTIVE: To develop a scale to quantify and discriminate orthostatic from non-orthostatic symptoms. In the current study, we present validation and reliability of orthostatic and non-orthostatic symptom scores taken from the orthostatic discriminate and severity scale (ODSS). METHODS: Validity and reliability were assessed in participants with and without orthostatic intolerance. Convergent validity was assessed by correlating symptoms scores with previously validated tools [autonomic symptom profile (ASP) and the orthostatic hypotension questionnaire (OHQ)]...

PURPOSE: To determine if autonomic symptoms are associated with previous Zika virus infection. METHODS: Case-control study including 35 patients with Zika virus infection without evidence of neurological disease and 105 controls. Symptoms of autonomic dysfunction were assessed with the composite autonomic symptom scale 31 (COMPASS-31). RESULTS: Patients with previous Zika virus infection had significantly higher COMPASS-31 score than controls regardless of age and sex (p = 0...
