Abstract

Aims: The aim of this study was to investigate the relationship between fatigue severity with vitamin D level, disease stage, anxiety and, physical activity level in patients with Parkinson’s disease (PD). Methods: This study included 66 (male=38, female=28) individuals diagnosed with PD.

Results: The study included 66 (male=38, female=28) individuals diagnosed with PD. Fatigue severity was assessed by the fatique severity scale, vitamin D level by blood test results, anxiety by the BAI, disease stage by HY staging, and physical activity level by the IPAQ-short form. In addition, a significant correlation was found between fatigue severity with vitamin D level, anxiety, disease stage, and physical activity level in men, women, and all patients (p
