Focusing attention on biological markers of acute stressor intensity: empirical evidence and limitations. NEUROSCIENCE AND BIOBEHAVIORAL REVIEWS. The availability of biological markers that objectively quantify stress is a highly relevant issue. However, experimental evidence suggests that most physiological changes elicited by emotional stressors do not reflect their intensity and are not useful for this purpose. Thus, we review exp...

Authors: Fontes MAP, Marzano LAS, Silva CC, Silva ACSE Abstract Despite the current availability of safe and efficient drugs for treating hypertension, a substantial number of patients are drug-resistant hypertensives. Aiming this condition, a relatively new approach named catheter-based renal denervation was developed. We have now a clinically relevant time window to review the efficacy of renal denervation for treating this form of hypertension. This short review addresses the physiological contribution of renal sympathetic nerves for blood pressure control and discusses the pros and cons of renal denervation pro...

Abstract Spinal cord injury (SCI) can have profound effects on the autonomic and cardiovascular systems, notably with injuries above high-thoracic levels that result in the development of autonomic dysreflexia (AD) characterized by volatile hypertension in response to exaggerated sympathetic reflexes triggered by afferent stimulation below the injury level. Pathophysiological changes associated with the development of AD include sprouting of both nociceptive afferents and ascending propriospinal 'relay' neurons below the injury, as well as dynamic changes in synaptic inputs onto sympathetic preganglionic neurons. ...

Our world has never witnessed a time of greater promise for improving human health. Many of today’s health advances have stemmed from a long arc of discovery that begins with strong, steady support for basic science. In large part because of fundamental research funded by the National Institutes of Health (NIH), which traces its roots to 1887, Americans are living longer, healthier lives. Life expectancy for a baby born in the U.S. has risen from 47 years in 1900 to more than 78 years today. Among the advances that have helped to make this possible are a 70% decline in the U.S. death rate from cardiovascular disease ...

In this narrative review, we summarize the current knowledge of neurally mediated blood pressure (BP) control and discuss how recently described epilepsy- and seizure-related BP alterations may contribute to premature mortality and sudden unexpected death in epilepsy (SUDEP). Although people with epilepsy display disturbed interictal autonomic function with a shift towards predominant sympathetic activity, prevalence of arterial hypertension is similar in people with and without epilepsy. BP is transiently increased in association with most types of epileptic seizures but may also decrease in some, illustrating that seizur...

AbstractAutonomic dysfunction is common in neuro-critical care patients and may compromise the function of various organs. Among the many diseases causing or being associated with autonomic dysfunction are traumatic brain injury, cerebrovascular diseases, epilepsy, Guillain –Barré syndrome (GBS), alcohol withdrawal syndrome, botulism and tetanus, among many others. Autonomic dysfunction may afflict various organs and may involve hyper- or hypo-activity of the sympathetic or parasympathetic system. In this short overview, we address only a small number of neuro-inten sive care diseases with autonomic dysfunctio...

Sympathetic nervous system regulation plays a crucial role in health and disease. Practically all major organs are subject to sympathetic influences and when autonomic dysfunction occurs, pathologic consequences can be dire. Abnormalities in sympathetic tone have been implicated in the pathogenesis of atrial and ventricular arrhythmias, myocardial infarction, heart failure, epilepsy, renal failure, hypertension, stroke, and diabetes, as well as other disease conditions [1 –3]. Recognition of this linkage across the decades has provided a significant impetus to develop reliable methods to monitor sympathetic tone in o...
