BACKGROUND Fabry patients have symptoms and signs compatible with autonomic dysfunction. These symptoms and signs are considered to be due to impairment of the peripheral nervous system, but findings indicative of autonomic neuropathy in other diseases, such as orthostatic intolerance and male sexual dysfunction, are infrequently reported in Fabry disease. The aim of our study was to investigat...

BACKGROUND Among diabetic patients autonomic neuropathy (AN) is one of the most frequent complications. This affects peripheral nervous system and thus results into erectile dysfunction (ED). The main objectives of the study were to determine the frequency of autonomic neuropathy (AN) in diabetic patients with ED and to find out the associated risk factors. METHODS In this descriptive case se...

Autonomic nervous system dysfunction is a common feature in uremia and may have a number of clinical sequelae. Simple cardiovascular reflex screening can be performed in patients during conservative treatment, on periodic dialysis therapy, or after kidney transplantation to diagnose and follow up autonomic function impairment. Other approaches, such as heart-rate variability studies in the freq...

INTRODUCTION Autonomic dysfunction has been theorized to be responsible for the increased risk of cardiovascular disease in obstructive sleep apnea (OSA). Previous studies did not control for the presence of impaired glucose regulation (IGR, comprising impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and diabetes) which is also associated with abnormalities in autonomic functio...

Cerebellar ataxia, neuropathy and vestibular areflexia syndrome (CANVAS) is a recently recognized neurodegenerative ganglionopathy. Prompted by the presence of symptomatic postural hypotension in two patients with CANVAS, we hypothesized that autonomic dysfunction may be an associated feature of the syndrome. We assessed symptoms of autonomic dysfunction and performed autonomic nervous system t...

capillary forms (Robbins, 1963). Thrombosis of the cavernous spaces and any stage of organization of the thrombi may be present. Some degree of fibrosis is usual and calcification can occur as was seen in our patient on radiological examination. Considering the pathological anatomy of a haemangioma, it is possible to surmise that red-cell fragmentation could occur in such a situation as a resul...

BACKGROUND There are no studies of autonomic function comparing Alzheimer's disease (AD), vascular dementia (VAD), dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD). AIMS To assess cardiovascular autonomic function in 39 patients with AD, 30 with VAD, 30 with DLB, 40 with PDD and 38 elderly controls by Ewing's battery of autonomic function tests and power spectral analysi...

Objectives Little is known about the relationship between autonomic dysfunction and sleep disturbances. This study aimed to identify patterns of sleep disturbances and autonomic dysfunction in children. Methods A retrospective chart review of 14 children who underwent sleep and autonomic testing was performed. Subjects were divided into three groups based on sudomotor Composite Autonomic Seve...

Multiple sclerosis (MS) is a chronic, progressive central neurological disease characterized by inflammation and demyelination. In patients with MS, dysregulation of the autonomic nervous system may present with various clinical symptoms including sweating abnormalities, urinary dysfunction, orthostatic dysregulation, gastrointestinal symptoms, and sexual dysfunction. These autonomic disturbanc...

Autonomic dysfunction is very common in patients with dementia, and its presence might also help in differential diagnosis among dementia subtypes. Various central nervous system structures affected in Alzheimer's disease are also implicated in autonomic nervous system regulation, and it has been hypothesized that the deficit in central cholinergic function observed in Alzheimer's disease could...
