BACKGROUND Autonomic nervous system dysfunction is commonly seen in multiple sclerosis patients and should be explored in the routine evaluation. Composite Autonomic Symptom Score questionnaire was validated as a self-assessment instrument of autonomic symptoms. OBJECTIVES Determine the frequency of autonomic symptoms in multiple sclerosis patients through a Portuguese version of Composite Au...

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...

Recent studies revealed cardiac autonomic dysfunction in patients with acute schizophrenia, which appears to be mainly related to reduced vagal and increased sympathetic modulation. To understand the significance of cardiac autonomic function in patients with schizophrenia, we extended these studies to relatives of patients. In this study, we assessed cardiac autonomic modulation in healthy fir...

Parkinson’s disease (PD) is a chronic, progressive, neurodegenerative disorder characterized by motor and non-motor manifestations. The male/female PD ratio is 3:2, with PD incidence varying between 10 and 15 in 100,000 people. PD prevalence increases with age, occurring in 1.5–2% of the population older than 65 years of age and in 3–5% of that older than 85 years of age. Patients with advanced...

nomic nervous system activity before surgery. Also, Jideus and colleagues concluded that ‘the diminished circadian variation in autonomic nervous system before surgery and the indirect signs of a higher parasympathetic activity in patients developing postoperative AF compared with patients remaining in sinus rhythm, may indicate a propensity for AF.’ Thus, impairment in autonomic nervous system...

BACKGROUND Intraocular pressure (IOP) may be partially under systemic vascular control. This study examined whether a correlation exists between blood and intraocular pressures in patients with autonomic dysfunction. METHODS AND RESULTS Eleven patients with 3 types of confirmed autonomic dysfunction (multiple system atrophy, pure autonomic failure, and baroreflex failure) were compared with a...
