Selegiline (L-deprenyl), a selective inhibitor of monoamine oxidase type B, is an established adjuvant to levodopa therapy in Parkinson's disease (PD). To evaluate whether selegiline also effects the severity and progression of autonomic nervous system dysfunction in PD, we studied autonomic functions by measuring cardiovascular responses to normal(More)
The aim of this study was to evaluate cardiovascular responses as a marker of autonomic nervous system (ANS) disturbances in patients with untreated Parkinson's disease (PD) and to assess the relationship between them and the clinical characteristics of PD. The ANS functions were investigated in 50 patients with PD and 55 healthy subjects by measuring(More)
OBJECTIVES Disorders of cardiovascular and other autonomic nervous system functions are often found in patients with temporal lobe epilepsy (TLE). Cardiovascular dysregulation in TLE has previously been quantified assessing traditional time and frequency domain measures of heart rate (HR) variability from short term ECG recordings. However, new complexity(More)

The aim of the present study was to examine the effects of nocturnal breathing disorders such as obstructive sleep apnoea (OSA) and snoring on developing dental arches. The study group comprised 41 children (22 males, 19 females, mean age 7.2 years, standard deviation 1.93) with diagnosed OSA. Age- and gender-matched groups of 41 snoring and 41(More)
Autonomic nervous system (ANS) involvement is frequently found in Parkinson's disease (PD), but its causal relationship to the disease itself and its medication is unclear. We evaluated the effects of PD medications on cardiovascular ANS functions. Heart rate (HR) responses to normal and deep breathing, the Valsalva manoeuvre and tilting, and blood pressure(More)
The cerebral effect of long term (mean 15.6, SD 8.9 years) and low (about 25 micrograms/m3 air) exposure to mercury vapour was studied in a group of 41 workers in a chlor-alkali plant and in a group of matched referents by electroencephalography (EEG). In the visually interpreted EEGs only a tendency for an increased number of EEG abnormalities, especially(More)
The autonomic nervous system (ANS) function of patients with Parkinson's disease (PD) was investigated in 30 patients with PD, and in 21 healthy subjects of similar age by utilizing cardiovascular reflex measurements as indicators. In deep breathing, in the Valsalva manoeuvre, and in the tilting test the heart rate variability (R-R variation) differed(More)
BACKGROUND This study was undertaken to evaluate if possible changes in stretch- and H-reflexes could be related to the changes in the EMG activity of the cooled lower leg muscles observed during a stretch-shortening cycle exercise. METHODS Eight subjects wearing shorts and jogging shoes were exposed once to 27 degrees C and twice to 10 degrees C for 60(More)
The sympathetic skin response (SSR) was used to evaluate sympathetic sudomotor activity in Parkinson disease (PD) and the effects of antiparkinsonian medication on the disease. We recorded SSRs to electric and auditory stimulation in 58 untreated patients with PD and in 20 healthy controls. In addition to amplitude and latency measurements, we examined the(More)
