Summary:Objective Patients with Parkinson's disease (PD) present with a variety of non‐motor symptoms including sensory complaints and mood disturbances. In the current pilot study, we aimed to explore pain complaints and the association between mood and pain in PD. We hypothesized that pain ratings would be elevated in patients with PD relative to controls. As PD is lateralized at onset and studies have found lateralization of some non‐motor symptoms in PD, we also hypothesized that PD patients would exhibit differing pain profiles depending on side of onset of the disease. Methods Twenty‐three PD patients (11 right‐onset (RPD), 12 left‐onset (LPD) disease), and 11 control participants (CS) completed a mood questionnaire (Depression Anxiety Stress Scale; DASS) as well as the short form of the McGill Pain Questionnaire. Results Both PD groups reported higher present pain intensity scores (p = 0.001), more evaluative pain intensity (p = 0.02), and more overall pain (p = 0.02) than control participants. There was a significant association between mood and all of the McGill pain ratings in the LPD patients, with those reporting more mood symptoms rating higher on all pain scales (all p‐values
