Unexpected deaths in people with PWS have a profound impact on families and communities. While not all deaths can be prevented, there is growing recognition that earlier identification of risk factors, improved understanding of PWS-specific health needs, and better communication between families and professionals may reduce preventable harm.
This Summit Meeting will explore practical strategies for recognising serious illness, responding appropriately to medical concerns and learning from the experiences of bereaved families. The session will combine clinical expertise, emerging research and lived experience to identify ways to improve care and outcomes for people with PWS.

Session overview
In this pre-recorded contribution, Jo Davies shares the story of her son Jacob and reflects on the circumstances surrounding his death. Through a mother’s perspective, the presentation offers a powerful and deeply personal insight into the realities of navigating health, social care and support systems for a person with PWS.
Drawing on her family’s experience, Jo explores lessons relating to food security, recognising signs of serious illness, communication between families and services, diabetes risk, and the importance of PWS-specific knowledge and training. By sharing Jacob’s story, she hopes to encourage learning, reflection and greater awareness of the factors that can influence health outcomes for people living with PWS, helping to improve care and prevent avoidable harm in the future.
Understanding Mortality Risk in PWS
Professor Maithé Tauber and Dr Gwenaelle Diene, France
What we know about causes of death in PWS, risks across the lifespan, warning signs and opportunities to reduce preventable harm.
Session and speaker information
What do we know about mortality risk in PWS, and how can families and healthcare professionals reduce preventable harm?
Drawing on the experience of the French National Reference Centre for Prader-Willi syndrome, Professor Maithé Tauber and Dr Gwenaelle Diene will examine the factors most frequently associated with mortality across the lifespan. The presentation will explore common causes of death, warning signs that may be overlooked, and practical strategies to help families and healthcare professionals identify and manage risks earlier. Attendees will gain valuable insights into reducing preventable harm and improving outcomes for people living with PWS.
Presenters
Professor Maithé Tauber is Professor of Pediatrics at the University of Toulouse, Director of the French Reference Centre for Prader-Willi syndrome, and Chair of the Scientific Council of Prader-Willi France. Her research has made a significant contribution to the understanding of PWS, including studies exploring the role of oxytocin in the syndrome.
Dr Gwenaelle Diene is a member of the multidisciplinary team at the French Reference Centre for Prader-Willi syndrome in Toulouse and will join Professor Tauber in presenting findings and clinical insights from the Centre’s work.
Dysphagia, Aspiration and Airway Risks
Roxann Diaz Gross, PhD, USA
Swallowing difficulties, aspiration and choking risks, including warning signs, management and prevention.
Session and speaker information
The need for the Heimlich maneuver, death from choking, and pulmonary infection occur in a disproportionally high number of persons with PWS. The widely held belief is that eating behaviors are responsible for choking and aspiration; yet, few investigations have sought to determine if swallowing impairments were present in persons with PWS. To address this research and clinical gap, simultaneous videofluoroscopy and nasal respiratory signals were used to record swallowing function and breathing/swallowing coordination in 30 participants with PWS. Under videofluoroscopy, the cohort showed disordered pharyngeal and esophageal swallowing with disturbances in timing, clearance, and coordination of swallowing with the respiratory cycle. No participant showed a sensory response such as attempting to clear residue or coughing; thereby supporting the lack of overt symptoms. We concluded that the high death rate from choking and pulmonary infection in children and adults with PWS may be related, in part, to underlying, asymptomatic dysphagia. The combination of rapid eating and dysphagia would increase the risk of aspiration-related morbidity and mortality.
Presenter
Roxann Diez Gross, PhD, CCC-SLP, ASHA Fellow, has over 40 years of clinical experience with a focus on the diagnosis and treatment of swallowing disorders (dysphagia). While an Assistant Professor in the Department of Otolaryngology at the University of Pittsburgh, she served as the Director of the Swallowing Disorders Center and principal investigator on several research grants that she had been awarded. Her research in the area of respiratory and swallowing interactions has resulted in multiple peer-reviewed and invited publications, as well as frequent invitations to lecture both nationally and internationally. Her research study that developed a method and apparatus for quantifying pharyngeal residue was granted a US patent (#7,555,329 B2). While at the Children’s Institute of Pittsburgh, Dr. Gross was the Director of Research while she also conducted studies on swallowing function in PWS. Currently, she is a Consultant and Clinical Specialist for Swallowing Diagnostics, Inc.
Gastrointestinal Health and Medical Emergencies
Ann O. Scheimann, MD, MBA, USA
Important gastrointestinal risks in PWS and recognising symptoms that require urgent medical attention.
Session and speaker information
Individuals with PWS are at increased risk of serious gastrointestinal complications, some of which can become life-threatening if not recognised and treated promptly. This session will explore common gastrointestinal concerns in PWS, including delayed gastric emptying, constipation, bowel obstruction and gastric rupture.
Attendees will learn about the signs and symptoms that may indicate an emerging medical emergency, when urgent medical assessment should be sought, and the practical steps families and healthcare professionals can take to support early recognition and intervention. This presentation will provide important guidance for anyone involved in the care of people with PWS.
Presenter
Dr. Scheimann received her doctorate of medicine at the University of Cincinnati School of Medicine and completed her pediatric residency and pediatric gastroenterology and nutrition fellowship at Baylor College of Medicine/Texas Children’s Hospital. She was full time faculty within the Division of Pediatric Gastroenterology and Nutrition at Baylor College of Medicine until 2000 when she moved to join the full-time faculty within the Department of Pediatrics/Division of Pediatric Gastroenterology at Johns Hopkins School of Medicine but remained adjunct faculty at Baylor College of Medicine directing the Prader-Willi Syndrome Clinic at Texas Children’s Hospital. Dr. Scheimann completed a Masters in Health Sciences Management at Johns Hopkins School of Business in 2005.

Learning from Bereavement: Improving Care in PWS
Gina Skourti and Dr Anne Livesey FRCP MRCPCH MRCGP, UK
What we can learn from families’ experiences, including recognising vulnerability, listening to families and identifying wider patterns of risk.
Session and speaker information
This presentation introduces research exploring deaths among people with Prader-Willi syndrome from the perspectives of close family members. Drawing on interviews with members of 14 bereaved families, the qualitative study examines the lives of individuals with PWS, their experiences of health and social care, and the circumstances surrounding their deaths.
Gina Skourti will present preliminary findings organised around three interconnected themes: the individual, the family and services. The emerging analysis suggests that potentially preventable harm may occur when individual needs, family knowledge and professional responsibilities become disconnected. Key issues identified by families include the application of mental capacity frameworks, fragmented care, reportedly unsafe environments, poor information sharing, and the exclusion of family expertise. The presentation will consider the implications of these findings for improving care and reducing the risk of avoidable harm in people with PWS.
Presenters
Gina Skourti is a mental health clinician and trained behaviour analyst with experience supporting people with learning disabilities and neurodivergent individuals across the lifespan. She currently works as a clinical lead in a mental health support service for children and young people and teaches on IAPT courses, focusing on autism and learning disabilities. She is also training as a counsellor and psychotherapist. Her particular interests include supporting caregivers and training professionals in neuroaffirming approaches to practice.
Dr Anne Livesey is a recently retired Consultant Developmental and Community Paediatrician with extensive experience in hospital paediatric endocrinology. For 20 years, Dr Livesey worked as part of a multidisciplinary Prader-Willi syndrome clinic at a children’s hospital in Sussex, England, supporting children and young people from across England and Wales. Her role extended beyond clinical care to include many of the wider implications of living with PWS, involving close collaboration with families and a range of health, education and social care services.
Dr Livesey has considerable experience reviewing the circumstances surrounding the deaths of children and young people, as well as the information and support provided to families following bereavement. In 2000, Dr Livesey developed a Sussex-wide multi-agency protocol for responding to unexpected child deaths and served as the Designated Paediatrician responsible for overseeing this work and the subsequent multi-agency reviews of all local child deaths. Both processes later became mandatory practice across England and Wales in 2008.
The live presentations will be followed by a panel discussion and audience questions, focusing on practical lessons for families, caregivers and healthcare professionals.
