Idiopathic parkinson’s disease and fatigue

Abstract

Introduction: Fatigue is a common non-motor symptom of Idiopathic Parkinson’s Disease (IPD). The aim is to research the relationship between fatigue of IPD patients and the clinical findings, of mood disorders. Material and methods: A total of 39 patients with IPD were included in the study. The relationship between fatigue severity and demographic characteristics and the treatment was evaluated in IPD. The severity of fatigue was evaluated by Fatigue Severity Scale (FSS). Motor impairment was scored by the modified Hoehn and Yahr scale. The patients were assessed for the presence of depression and anxiety with the Hospital Anxiety and Depression Scale (HADS). Results: The mean age of the patients was 70.62 ± 8.35 years. 23 were men and 16 were women. The mean disease duration was 6.18 ± 3.35 years. The patients were assigned into two groups according to the presence of fatigue measured by FSS with less than 5 (Group I) and 5 or more (Group II). There were no statistically significant differences between the two groups with respect to mean age, mean age of onset, and mean disease duration of the patients (p > 0.05). There were no significant differences between the two groups for HADS depression, anxiety values, and terms of antiparkinsonian therapies (p > 0.05). The severity of fatigue was correlated with the HADS anxiety levels (p < 0.05). Discussion: Fatigue is an important non-motor symptom that is underestimated in clinical follow-up. We didn’t find any correlation between fatigue and age, duration of disease onset, or drug use. There was no significant correlation between the fatigue score and depression, and pain. However, the fatigue scores were higher in patients with high anxiety scores and females.
