BACKGROUND AND PURPOSE Autonomic dysfunction has been described as a frequent complication of stroke that could involve the cardiac, respiratory, sudomotor, and sexual systems. Cardiac autonomic dysfunction after stroke is one of the most recognized and has been described to increase the rate of mortality and morbidity. METHODS We report two cases of stroke-one hemorrhagic and one ischemic-an...

PURPOSE Objective is to evaluate cardiovascular autonomic function in SLE by simple non-invasive tests. METHODS A case control study was carried out involving 18-50 yrs old previously diagnosed SLE patients and same number of age and sex-matched controls. Parasympathetic function was assessed by heart rate (HR) response to Valsalva maneuver, deep breathing and standing. Sympathetic function w...

The vestibular nervous system senses linear and angular acceleration upon the head during postural change generates nerve activity changes. autonomic regulates involuntary physiologic processes throughout peripheral central systems. systems interplay several brain regions to maintain homeostasis changes, called vestibulo-autonomic reflex. In this review, we first contemplated anatomic propertie...

In Multiple Sclerosis (MS) abnormalities of autonomic nervous system and cardiac parameters have been reported separately. Our objectives were to investigate whether MS patients with moderate disability and autonomic dysfunction presented alterations in cardiac function under stress and to see whether these changes contribute to MS fatigue. In 33 MS patients we examined the cardiovascular auton...

Autonomic neuropathy is one of the most common complications of diabetes mellitus (DM). The etiology of autonomic impairment is not well-understood, yet. There is need for studies to investigate the cause-effect relationships of inflammation and/or endothelial dysfunction and diabetic autonomic neuropathy. Only a few reports have mentioned autonomic neuropathy in individuals with impaired gluco...

Epilepsy and seizures can have a dramatic effect on the autonomic nervous system by involvement of the central autonomic control centers. The peri-ictal changes can lead to short-term alteration of cardiac functions in patients with seizures, and are partially hemispheric specific. Changes in heart rhythm, conduction and even subtle signs of ischemia have been reported. Ictal asystole and the l...

BACKGROUND AND OBJECTIVE COPD is associated with impaired health-related quality of life (HRQL) and cardiac autonomic dysfunction. Data describing the association between these factors in patients with COPD are mostly lacking. The objective of this study was to evaluate whether there is an association between cardiac autonomic dysfunction and HRQL in COPD. METHODS We studied 60 patients with ...

BACKGROUND Autonomic neuropathy is frequently present in dialysis patients. In addition, deterioration of autonomic function occurs with ageing. This study examines the true prevalence of autonomic neuropathy in elderly dialysis patients and questions whether the combination of age and uraemia further increases the chance of dysautonomia being present. METHODS We compared the results of five ...

The effect of autonomic dysfunctions on anemia in various neurological disorders, such as familial amyloidotic polyneuropathy (FAP) Type I, pandysautonomia, and Shy-Drager syndrome was examined. As a control, hemograms of patients with amyotrophic lateral sclerosis (ALS), which is known to be free from autonomic dysfunction, was compared with patients with the above neurological disorders. FAP ...

BACKGROUND The authors of prior small studies raised the hypothesis that symptoms in veterans of the 1991 Gulf War, such as chronic diarrhea, dizziness, fatigue, and sexual dysfunction, are due to cholinergic autonomic dysfunction. OBJECTIVE To perform a confirmatory test of this prestated hypothesis in a larger, representative sample of Gulf War veterans. DESIGN Nested case-control study. ...
