Methods of evaluation of autonomic nervous system function

Disturbances of the autonomic nervous system play a crucial role in the pathogenesis and clinical course of many diseases. Recently, rapid development has occurred in the clinical assessment of autonomic function. Various procedures have been described as diagnostic tools to monitor autonomic dysfunction. Some of them are mostly used for research purposes. Many, however, have found their place ...

Assessment of autonomic nervous system function in patients with non-alcoholic cirrhosis

Automatic dysfunction may contribute to the hemodynamic disturbances in cirrhosis. Tests of autonomic function were performed in 31 patients with non-alcoholic cirrhosis and 30 healthy subjects. Patients were divided into 3 groups according to child- Pugh,s classification ( A.B.C). The patients with moderate and severe cirrhosis( child B,C) had significant parasympathetic disturbance ( in the v...

Breath holding spells: evaluation of autonomic nervous system function.

This study attempted to determine noninvasively whether a dysregulation of autonomic reflexes exists in children with breath holding spells (BHS). Fifty children between 13 to 47 months of age who had experienced BHS were evaluated at a time when they stopped having spells, for autonomic nervous system (ANS) dysfunction. The results were compared with the test results of control group of 100 no...

Autonomic nervous system function in Huntington's disease.

OBJECTIVE To investigate whether Huntington's disease (HD) affects autonomic nervous system (ANS) functioning. METHODS Twenty patients with HD who had positive genetic test results underwent standardised ANS function tests including sympathetic skin responses (SSRs) of the hands and feet, measurements of heart rate variability (HRV), both during five minutes of resting and deep respiration, a...
