Effects of Meditation and Yoga on Anxiety, Depression and Chronic Inflammation in Patients with Parkinson's Disease: A Randomized Clinical Trial.

Introduction: Clinical guidelines recommend a holistic approach to Parkinson's disease (PD) care, yet randomized trials examining mindfulness-based interventions in this context are scarce. This study investigated the effects of two mindfulness practices - meditation and yoga - on biopsychosocial outcomes in PD patients, including anxiety symptoms, depressive symptoms, motor/nonmotor symptoms, health-related quality-of-life (HRQOL), mindfulness, and stress and inflammation biomarkers, compared to usual care.

Methods: 159 participants with a clinical diagnosis of idiopathic PD and a Hoehn and Yahr stage of 1, 2, and 3, were randomized into meditation (n = 53), yoga (n = 52), and control (n = 54).
