• Abstract Background Swallowing disturbances are an important issue in Parkinson's disease (PD) as several studies have shown that they are associated with increased risk of aspiration pneumonia and mortality. Information about factors related to swallowing disturbances, such as disease duration, age at assessment and concomitant dementia, is limited and would be useful for their management. Methods All consecutive PD out-patients evaluated at a movement disorders clinic over a 7-year period (2007–2014), were included in the present retrospective study. Presence of symptomatic swallowing disturbances was assessed using the specific item of the Non Motor Symptom Questionnaire. Results In the whole PD population ( N  = 6462), prevalence of symptomatic swallowing disturbances was 11.7% (95%CI, 10.9–12.5). Multivariable logistic regression analysis (adjusted for education) disclosed a significant interaction between disease duration and gender ( P  = 0.009). In both gender strata, swallowing disturbances were significantly associated with longer disease duration and dementia ( P  < 0.001 for all). A significant effect for age at assessment was also found in male patients. In non-demented patients, swallowing disturbances were associated with male gender, age and disease duration ( P  < 0.02 for all). In demented patients an association was found only with male gender ( P  = 0.018) and disease duration ( P  < 0.001). Conclusions Gender, age, disease duration and dementia all seem to contribute to the occurrence of swallowing disturbances independently. However, the role played by these factors in sub-groups of patients stratified by gender and concomitant dementia suggests that swallowing disturbances are likely related to different neuro-degenerative patterns within the brain. The underlying mechanisms deserve further investigation.
