The goal of this observational study is to learn about swallowing difficulties (dysphagia) in patients living with myotonic dystrophy type 1 (DM1). The main questions it aims to answer are: whether the size and structure of the muscles involved in swallowing differ to those without the disease how the size and structure of muscles may associate with swallowing function and swallowing symptoms in this group. Participants will undergo a range of tests including: Ultrasound (US) assessment of the muscles involved in swallowing An x-ray swallowing study (known as videofluoroscopy) Assessment of swallowing symptoms, including questionnaires Assessments of mobility, activity and breathing Assessments of quality of life and wellbeing

Dysphagia, Oropharyngeal
This study will explore swallowing difficulties (dysphagia) caused by Myotonic Dystrophy Type 1 (DM1). Dysphagia causes food, drink and saliva to travel onto the lungs (aspiration) and can lead to pneumonia. Aspiration pneumonia is frequent and accounts for over 40% of deaths in DM1. Dysphagia also causes fear and anxiety which can lead to permanent lifestyle changes. A better understanding of dysphagia in DM1 will improve our assessment and treatment and reduce its life-changing consequences. This research aims to define the dysphagia profile of people with DM1 (pwDM1) across the domains of structure, function, experience, and wellbeing by: Investigating the size and structure of muscles involved in swallowing in patients with and without DM1. Exploring how muscle size and structure are associated with i) swallowing function and ii) symptoms Exploring how swallowing function is associated with i) symptoms, ii) patient and caregiver wellbeing and iii) other aspects of DM1 such as walking and breathing. People aged 18+ with a confirmed diagnosis of DM1 will be invited to take part. Approximately 90 pwDM1 will be recruited. They will undergo a battery of tests including: Ultrasound (US) assessment of the muscles involved in swallowing An x-ray swallowing study (known as videofluoroscopy) Assessment of swallowing symptoms, including questionnaires Assessments of mobility, activity and breathing Assessments of quality of life and wellbeing A sub-group of 20 pwDM1 will also undergo magnetic resonance imaging (MRI) of the muscles involved in swallowing to examine in detail the changes in seen on ultrasound. Approximately 60 people without DM1 will act as a control group for the US assessments. Primary caregivers of those with DM1 will be invited to complete a wellbeing questionnaire. Data will be analysed using statistical methods and findings will be used to develop clinical practice recommendations for the assessment and treatment of dysphagia in DM1. This study is part of an NIHR-funded clinical doctoral research fellowship (CDRF) and will take place at The National Hospital for Neurology and Neurosurgery (NHNN) in London. The maximum timescale for the study from opening recruitment to data collection of the final participant is 18 months (approx. 1st April 2023 - 30th September 2024).}}
