Methods: Consecutive ambulatory patients, who were on dopaminergic treatment for >= 1 year, were included in this multicentre, observational cross-sectional study. In a single visit, WO was diagnosed based on neurologist assessment as well as using the validated Italian version of a patient self-rated 19-question Wearing-Off Questionnaire (WOQ-19); WO was defined for scores >= 2. QoL was evaluated by the 8-item Parkinson's Disease Questionnaire (PDQ-8).
Objective: Assessing the frequency of Wearing-Off (WO) in Parkinson's disease (PD) patients, and its impact on Quality of Life (QoL).
