Autonomic Nervous System Dysfunction in Pediatric Sepsis

Autonomic Nervous System Dysfunction in Parkinson's Disease.

Autonomic nervous system (ANS) dysfunction is common in Parkinson's disease (PD), affects 70% to 80% of patients, and causes significant morbidity and discomfort. Autonomic nervous system dysfunction symptoms in PD include sexual dysfunction, swallowing and gastrointestinal disorders, bowel and bladder abnormalities, sleep disturbances, and derangements of cardiovascular regulation, particularl...

Autonomic nervous system dysfunction in sclerodermic and primary Raynaud's phenomenon.

Our aim was to investigate the sympathetic hyperactivity of systemic sclerosis that may lead to greater morbidity and mortality from cardiovascular events. We analysed the sympathetic (low-frequency) and vagal (high-frequency) components of heart rate variability, in supine and upright positions, in 10 patients with systemic sclerosis, 12 patients with primary Raynaud's phenomenon and 14 contro...

Autonomic nervous system dysfunction in workers exposed to organic solvents.

Tests for cardiovascular function were made in 34 workers exposed to organic solvents for several years (mean 16.2 years). The results were compared with those of 52 healthy subjects. All the cardiovascular parameters were lower in the exposed group. The exposed subjects with evidence of peripheral neuropathy had lower values than those without neuropathy. The findings suggest that peripheral p...

Autonomic Nervous System Testing

A utonomic nervous system testing is used to document diabetic autonomic failure. Diabetic autonomic failure is defined as impaired function of the peripheral autonomic nervous system and can be divided into two categories: 1) autonomic neuropathy, in which there is a structural lesion of the peripheral autonomic neuron and 2) functional autonomic failure, in which no known structural lesion oc...
