Topic: Autonomic function


  
  The Autonomic Assessment Report
A New Noninvasive Measure of Autonomic Function and Balance.
Power spectral density analysis is used to assess how power is distributed as a function of frequency, providing a means to quantify autonomic balance at any given point in the 24-hour period, as well as to chart the circadian rhythms of the different branches of the autonomic nervous system.
Autonomic imbalances have been implicated in a wide variety of pathologies, including depression, fatigue, premenstrual syndrome, hypertension, diabetes mellitus, ischemic heart disease, coronary heart disease and environmental sensitivity.

 Autonomic Function
Autonomic nervous system function is associated with insulin dynamics and obesity in adults.
This diagnostic trial is a cross-sectional study to assess and categorize insulin dynamics and examine correlations with autonomic tone in obese children, age 0-17 years, who have met the inclusion and exclusion criteria.
This problem is clinically important because the preservation of residual beta cell function during the first five years of diabetes leads to improvement in glycemic control (lower sugars) and has a long-lasting benefit with respect to the prevention of complications.

 Ansar - Technical Review : Diabetic Autonomic Neurology - Standard of Care
Disruption of rnicrovascular skin blood flow and sudomotor function may be among the earliest manifestations of DAN and lead to dry skin, loss of sweating, and the development of issures and cracks that allow microorganisms to enter.
Meta-anaryses of published data demonstrate that reduced cardiovascular autonomic function as measured by heart rate variability (HRV) is strongly (i.e.relative risk is doubled) associated with an increased risk of silent myocardial ischemia and mortality.
Other forms of autonomic neuropathy can be evaluated with specialized tests, but these are less standardized and less available than commonly used tests of cardiovascular autonomic function, which quantify toss of HRV.

The autonomic nerve fibers form a subsidiary system that regulates the iris of the eye and the smooth-muscle action of the heart, blood vessels, glands, lungs, stomach, colon, bladder, and other visceral organs not subject to willful control.
All of the fibers of the autonomic nervous system are motor channels, and their impulses arise from the nerve tissue itself, so that the organs they innervate perform more or less involuntarily and do not require stimulation to function.
Autonomic nerve fibers exit from the central nervous system as part of other peripheral nerves but branch from them to form two more subsystems: the sympathetic and parasympathetic nervous systems, the actions of which usually oppose each other.

Long-term activation of spinal and extraspinal nociceptive afferents contributes to the stimulation of the autonomic nervous system that may in turn have a deleterious effect over time on visceral function.
The measurement protocols being utilized to assess the function of the autonomic nervous system are heart rate variability, blood pressure variability, baroreceptor sensitivity, skin conductance and peripheral skin temperature.

All of the cardiac autonomic tests were significantly different in the high- and the low-Hb[A.sub.1c] groups, and the most favorable scores for all tests were seen in the low-Hb[A.sub.1c] group.
Cardiac autonomic function was preserved with Hb[A.sub.1c] <8.4%, whereas cardiac autonomic dysfunction was impaired in the group with Hb[A.sub.1c] [greater than or equal to] 8.4%.
Reduced cardiovascular autonomic function is associated with increased mortality in both type 1 and type 2 diabetes (1-4).

Abstract: Comprehensive Study of Autonomic Function in a Population with Primary Sjögren's Syndrome.
Autonomic nervous system disorders have been described in patients with primary Sjögren's syndrome (SS), but the results in controlled studies have been contradictory, varying from normal to sympathetic or parasympathetic dysfunction.
The prevalence of autonomic dysfunction is not increased in patients with primary SS compared to the general population.

Since corticosteroid treatment may also influence autonomic function by improving small vessel vasculitis affecting vasa nervosum or decreasing the production of autoantibodies against neurotransmitter receptors, the patients taking corticosteroids were also analyzed in a subgroup.
While autonomic disorders have definitively been described in some patients with primary SS, our study suggests that significant autonomic neuropathy or dysfunction is rare in primary SS or may only affect some subgroups of patients.
To detect minor variations in the function of the autonomic regulatory system, which are possibly restricted to a subgroup of SS patients, larger series of patients with properly matched general population based controls should be studied.

 Assessment of Autonomic Function and Balance
While it has been suggested that patients with CFS may have impaired autonomic nervous system function, there have been few studies that have examined this question directly.
The purpose of this study was to determine if there were differences in autonomic function, as assessed by 24-hour heart rate variability (HRV) analysis, in 22 CFS patients (age range 31-69, mean age 45.5) as compared to healthy age and sex-matched controls.
Our results indicate that autonomic function is indeed impaired in CFS patients, as both sympathetic and parasympathetic activity are significantly depressed with respect to healthy age and sex-matched controls.

WHO IS IN Due to breathing’s potential dominance of the autonomic nervous system anything you do 5,000 to 30,000 times a day or two to five hundred million times per life time will influence you positively or negatively in many ways.
ANS dysfunction can be caused by toxicity of the brain stem and/or the autonomic ganglia, infections and nutrient deficiencies, by scar tissue and mechanical compression and postures influencing ANS fibers and ganglia.
"Fight or Flight: In weighing cardiac risk factors, doctors are overlooking autonomic tone" This article goes quite deep into the science of the ANS in a very enlightened way and concern for attention to the sympathetic and parasympathetic aspects but as you can see it completely overlooks the influence the breathing has on all that.

 24-hour patterns of cardiac autonomic function improves post kidney and kidney-pancreas transplant.   (Site not responding. Last check: 2007-10-15)
However, it is unknown if patients experience improvement in 24-hour patters of cardiac autonomic function (CAF) after kidney (K) or kidney-pancreas (KP) transplant.
The more pronounced circadian improvement is consistent with the theoretical premise that these measures are the last to show compromised function.
If so, these measures of 24-hour HRV could be used to monitor the restoration of cardiac autonomic function and identify patients at increased risk of morbid events.

The autonomic nervous system is the normally involuntary or unconscious division of the peripheral nervous system.
Everything from salivation and digestion to heart rate, respiratory rate, pancreatic function, liver and gallbladder function, and urine excretion through the kidneys, ureters and bladder, are only a few of the things that fall under autonomic control.
The impact of this is reduced healing, increased hypertension, facilitated segments, changes in endocrine function impacting metabolism, brain function and ultimately all homeostatic mechanisms.
