Abstract

Objectives: This study aims to investigate whether mean platelet volume (MPV) in peripheral blood of patients with Parkinson’s disease (PD) is an indicator of the disease and the severity of disease.

Patients and Methods: Between April 2013 and June 2014, a total of 80 patients diagnosed with Parkinson’s disease and 80 healthy volunteers for control group were enrolled in this study and their blood measurements were compared. Parkinson’s disease patients were examined by using Hoehn and Yahr scale (HYS), which is a scale for Parkinson’s disease severity.

Results: Platelet count and MPV were found similar between the groups. Mean platelet volume correlated negatively with HYS score (p<0.001, r= -0.576).

Conclusion: Vascular risk factors may not play a role in the pathogenesis of PD. The negative relationship between the severity of disease and MPV suggested that the inflammation theory might play a more important role in the later stages of the disease.
