Association between Religiousness and Quality of Life among Patients in Brazil diagnosed with Idiopathic Parkinson's Disease

Abstract

The importance of religiousness in idiopathic Parkinson's disease (IPD) has been the subject of conflicting research. The impact of religiousness on quality of life and depressive symptoms has also been poorly studied in this population. This study investigated the correlation between religiousness and quality of life in patients with IPD. We evaluated 37 patients with IPD (according to the criteria of the Movement Disorders Society) who were from an outpatient clinic specializing in movement disorders in Brazil. We assessed the patients using the Duke University Religion Index and scales for motor impairment, cognition, quality of life, and depression. Spearman’s test was used to check for possible correlations between the different dimensions of religiousness and the clinical variables analyzed. Patients with a worse quality of life and more depressive symptoms showed greater intrinsic religiousness.
