**Parkinson's Disease: Study of the Link Between Gait Freezing and Oropharyngeal Freezing** Parkinson's disease is a brain disorder that makes it hard to control movements. Many patients struggle with **dysphagia**, a swallowing problem. Dysphagia affects eating, drinking, and even taking medicine. It can cause serious issues like weight loss, dehydration, and even lung infections. Oropharyngeal freezing, a type of dysphagia, is when the tongue moves repetitively, making swallowing difficult and potentially dangerous. This study looks at whether there is a connection between **gait freezing** (difficulty in walking) and oropharyngeal freezing in Parkinson's patients. By understanding this link, doctors might help patients earlier, preventing complications. **Key Points:** - The study involves two groups of Parkinson's patients: those with and without gait freezing. - Participation requires being over 18 with diagnosed Parkinson's disease. - The study will use questionnaires to explore the connection between walking and swallowing difficulties. **Note:** People with other neurological issues or those who can't eat by mouth are not eligible for this study.
