Trial Outcomes & Findings for The Effect of Pramipexole on Metabolic Network Activity Compared With Levodopa in Early Parkinson's Disease (NCT NCT01470859)

NCT ID: NCT01470859

Last Updated: 2015-10-21

Results Overview

The brain network activity is evaluated by Parkinson's disease-related spatial covariance pattern(PDRP) value (Z score). The change of brain network activity is calculated by the PDRP value (Z score) at V5 - the PDRP value (Z score) at V1.

SECONDARY outcome

Timeframe: twice baseline and 1 year

The Hoehn and Yahr scale is a commonly used scale for describing how the symptoms of Parkinson's disease progress and the disease stages. Bigger numbers indicate more symptoms and disease progression. H\&Y stage range from 0-5; the greater, the more severe. The H\&Y stages of patients were evaluated at baseline (1st visit, V1), and 1 year after baseline (final visit, V5).
