Understanding swallowing difficulties in myotonic dystrophy type 1

A Multidimensional Profile of Dysphagia in People Living With Myotonic Dystrophy Type 1 (plwDM1)

Observational University College, London · NCT05865483

This study is trying to understand swallowing problems in people with myotonic dystrophy type 1 to see how muscle size and structure affect their ability to swallow.

What this trial studies

This observational study aims to investigate swallowing difficulties, known as dysphagia, in patients with myotonic dystrophy type 1 (DM1). It will assess the size and structure of the muscles involved in swallowing and how these factors relate to swallowing function and symptoms. Participants will undergo various tests, including ultrasound assessments, videofluoroscopy, and questionnaires to evaluate their swallowing symptoms and overall wellbeing. The goal is to enhance the understanding of dysphagia in DM1 to improve assessment and treatment strategies.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with a genetically confirmed diagnosis of myotonic dystrophy type 1 who can consume at least five sips of liquid by mouth.

Not a fit: Patients with conditions affecting swallowing muscle composition or function, such as a history of stroke or throat cancer, or those unable to eat or drink by mouth, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better management and treatment of dysphagia in patients with myotonic dystrophy type 1, potentially reducing life-threatening complications.

How similar studies have performed: While there have been studies on dysphagia in various conditions, this specific focus on myotonic dystrophy type 1 is relatively novel and untested.
