LINEAR ASSESSMENT OF CEREBRAL AUTOREGULATION IN IDIOPATHIC PARKINSON'S DISEASE
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2016, Vol 8, Issue 2
Abstract
Parkinson’s disease cases have been on the rise in the recent years, which promoted several different researches into the disorder. However, there hasn’t much research been done in the non-motor aspects of the disease. This study aims to improve the understanding of one of the non-motor symptoms of Parkinson’s disease. Specifically, this research aims to further understand cerebral autoregulation in patients with Parkinson’s disease. In order to achieve this aim, 25 subjects were recruited, with 11 healthy controls and 14 patients with Parkinson’s disease. The continuous blood pressure and continuous cerebral blood flow velocity of all subjects were recorded and processed while the subjects were at rest, tilt-up, and during hyperventilation. Linear signal and system analysis techniques were applied such as the power spectral density analysis and cross-correlation function analysis. Results showed that patients with Parkinson’s disease did not show a significant difference from the control group while at rest and after tilt-up. However, there was a significant difference between the groups during hyperventilation. The results obtained in this study suggested that the metabolic regulatory pathway for cerebral autoregulation is impaired in patients with Parkinson’s disease.
