This study evaluated the frequency of obsessive-compulsive disorder (OCD), obsessive-compulsive symptoms (OCS), and related disorders (e.g., tic disorders, trichotillomania, and body dysmorphic disorder) in 100 patients with Parkinson's disease (PD) and 100 individually matched controls. When compared with controls, OCD, OCS, and related disorders were not higher in PD. Findings revealed an association of some OCS with left side motor symptom predominance in PD patients, particularly for symmetry and ordering/arranging. These findings suggest that the right hemisphere likely functions in the expression of OCS.
本研究评估了100例帕金森病（PD）患者和100例个体匹配对照者中强迫症（OCD）、强迫症状（OCS）及相关障碍（如抽动障碍、拔毛癖和躯体变形障碍）的发生率。与对照组相比，PD患者中OCD、OCS及相关障碍的发生率并不更高。研究结果显示，PD患者中某些OCS与左侧运动症状优势相关，尤其是对称和排序/排列方面。这些发现表明，右半球可能在OCS的表现中发挥作用。
