Consequently, PPP remains difficult to identify, even for clinicians with expertise in Parkinson's disease.\n\nNevertheless, patients with Parkinson's disease who experience PPP appear to exhibit certain demographic and clinical characteristics that may help distinguish them from other patients, including a poorer motor response to levodopa, a stronger association with sleep disturbances, and cognitive and behavioral features such as impulse control disorders (ICDs). PPP may therefore be associated with a specific disease phenotype supported by distinct pathophysiological mechanisms.\n\nRecently, a disease progression model proposed the existence of a \"Brain-First\" subtype (characterized by disease onset in the brainstem) and a \"Body-First\" subtype (characterized by disease onset in the gastrointestinal system). Several clinical markers appear to distinguish these subtypes, notably the presence of REM sleep behavior disorder (RBD), which has been associated with the Body-First phenotype.\n\nThe association between PPP and RBD, as well as between PPP and the Body-First subtype, has never been investigated. We hypothesize that PPP may be associated with several clinical markers of the Body-First phenotype. Identifying such associations could facilitate the routine clinical diagnosis of PPP and, consequently, improve its management, which remains inadequate at present.\n\nThe primary objective is to assess the proportion of patients with primary parkinsonian pain according to the presence of probable RBD in Parkinson's disease.\n\nThis prospective, cross-sectional, non-interventional category 3 study (RIPH 3) will be conducted in 300 patients. Patients contacted through the France Parkinson Association and interested in participating in the study will be able to access the online questionnaire via a QR code or a web link. Completion of the questionnaire is expected to take no more than 15 minutes.
