Autonomic nervous system function in Huntington's disease

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...

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...

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 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...
