Mapping public knowledge of Parkinson’s disease in Portugal: a cross-sectional survey of knowledge, perceptions and attitudes

AIMS: Research addressing knowledge about Parkinson's disease has grown remarkably. However, there is a scarcity of insight into the current state of knowledge in Portugal. Given the growing prevalence of Parkinson's disease, a comprehensive understanding of this scenario is a vital step toward improving health literacy. This study aims to explore public knowledge, perceptions and attitudes toward Parkinson's disease in the Portuguese population. METHODS: A total of 784 individuals completed an online survey evaluating knowledge of Parkinson's disease, perceptions and attitudes. The survey was adapted from existing questionnaires on the topic for the purposes of this study and disseminated online. RESULTS: Participants showed a good level of knowledge about Parkinson's disease. Although motor symptoms were greatly recognized, knowledge about non-motor symptomatology was considered insufficient. Women, younger ages (18-34 years) and those with superior education presented higher levels of knowledge. Misconceptions about certain aspects of the disease were identified, as well as some negative perceptions and attitudes toward Parkinson's disease. CONCLUSION: This study sheds light on a relevant gap in public knowledge about Parkinson's disease, which is closely related to its most unnoticed side-the wider spectrum of non-motor symptomatology. Implications for public health campaigns and specialized interventions are discussed.
