iv Consensus Study Reports published by the National Academies of Sciences, Engineering, and Medicine document the evidence-based consensus on the studyâs statement of task by an authoring committee of experts. Reports typically include findings, conclusions, and recommendations based on information gathered by the committee and the committeeâs deliberations. Each report has been subjected to a rigorous and independent peer-review process, and it represents the position of the National Academies on the statement of task. Proceedings published by the National Academies of Sciences, Engineering, and Medicine chronicle the presentations and discussions at a workshop, symposium, or other event convened by the National Academies. The statements and opinions contained in proceedings are those of the participants and are not endorsed by other participants, the planning committee, or the National Academies. Rapid Expert Consultations published by the National Academies of Sciences, Engineering, and Medicine are authored by subject-matter experts on narrowly focused topics that can be supported by a body of evidence. The discussions contained in rapid expert consultations are considered those of the authors and do not contain policy recommendations. Rapid expert consultations are reviewed by the institution before release.

viii Acknowledgments The committee and project staff extend their gratitude to the many people and organizations who were critical in supporting and informing the committeeâs work. This study was sponsored by the National Institutes of Health (NIH) and, in particular, was supported by the National Institute of Neurological Diseases and Stroke (NINDS). The committee thanks NIH and NINDS for their support, and the committee thanks Congress for initiating this important study. People with amyotrophic lateral sclerosis (ALS), their caregivers and family members, representatives of ALS nonprofit organizations, researchers, and clinicians graciously offered their expertise and perspectives throughout the study process. This information was not only useful but also courageous, heartfelt, and inspiring. The committee heard from many people in different ways throughout the study and would like to extend its appreciation to each. Over the course of its meetings, the committee heard from many people who shared their stories about ALS. This allowed the committee to center their work in the real-world lived experiences of those living with and affected by this disease, as well as to gain valuable insight as to the challenges and opportunities faced by those who fight against ALS in their daily lives, at labs or clinics, and alongside countless community organizations. The committee thanks the many participants in its public sessions: Lori Banker-Horner, James Berry, Sunny Brous, Katrina Byrd, Nora Capocci, Blair Casey, Jim Clingman, Sylvia Clingman, Cathy Collet, Norah Crossnohere, Penny Dacks, Dan Doctoroff, Sonya Elling, Ron Faretra, Albert Faro, Sarah Fontaine, Renee Golden, John Hansen-Flaschen, Bob Hebron, Terry Heiman-Patterson, Colleen Hoarty, Collin Hovinga, Justin Ichida, Vanessa Jackson, Asia Jami, Desiree Galvez Kessler, Lisa Latts, Ashley Lee, Melanie Lendnal, Joanne Lynn, Paul Mehta, Paul Melmeyer, Indu Navar, Siobhan Pandya, Juliet Pierce, Terri Postma, Kristin Rankin, Julian Rodriguez, Bruce Rosenblum, Paul Seifert, Jean Swidler, Neil Thakur, Fernando Vieira, and William Woods. The committee also benefited from the perspectives of six individuals appointed as lived experience consultants (volunteers). The lived experience consultants provided reflections on some excerpts of draft report text between January and March 2024. The committee expresses its gratitude to Michael Cosgray, Desiree Galvez Kessler, Bernadine A. Okeke, Ann Oliff, Kristin Rankin, and Julian (Jules) Rodriguez for their participation in the study process as lived experience consultants. The committee also thanks Sarah Lunsford, who served as a consultant to organize many of these public engagement opportunities. The staff of the National Academies of Sciences, Engineering, and Medicine contributed in many ways throughout the study process. The committee extends its sincerest gratitude to the study team for their hard work and dedication throughout this project: Rebecca A. English, Lyle Carrera, and Ashley Bologna. The committee is grateful for the many staff within the Health and Medicine Division who provided support for the project. Special thanks are extended to Christie Bell, senior financial business partner; Lori Brenig, editorial projects coordinator; and Mark Goodin for his editorial assistance in preparing the report.

xv Preface Amyotrophic lateral sclerosis (ALS) is a terrible, inevitably fatal disease. Receiving a diagnosis of ALS is devastating for people living with ALS, their families, and their caregivers. Dealing with this illness requires a complex array of medical and support service interventions, and the intensity of care required increases exponentially over time. This report lays out an agenda that, if implemented, would provide greater and more equitable access to state-of-the-art multidisciplinary care, accelerate the development of more effective treatments, improve the quality of life and health of those individuals suffering from the illness both now and in the future, and provide better support for their families and caregivers. Implementing this agenda would go far toward the goal set in the committeeâs charge of making ALS a livable disease within a decade. This consensus report is the product of a committee of scientific and clinical experts from a variety of fields, as well as individuals living with the disease and people at clear risk for developing it. In addition, the committee met with a variety of other people living with the illness and asked them to reflect on the relevance of the committeeâs thinking and its potential recommendations. Including these individuals in our work helped greatly to ground the committeeâs work in real-life experiences and, I believe, significantly improved both the quality of this report and the appropriateness of its recommendations. As discussed in the report, the committee was aware that at the same time it was working on this project, many other, often parallel projects with similar goals were ongoing. We tried to remain cognizant of those efforts in framing our report and recommendations so as to avoid inadvertent conflicts or excessive duplication in strategies for accomplishing our shared goals. Achieving the vision underlying this report will require commitment and leadership from many different stakeholders. Some of the reportâs recommendations require substantial resources, but their impacts will be great for the more than 30,000 individuals living with ALS and the thousands more who are at clear risk of developing the disease. The steps recommended here include developing a comprehensive multidisciplinary care and research network that would do much to ensure substantially more equitable access to state-of-the-art care for all individuals with ALS, reduce unacceptably long delays in receiving an accurate diagnosis, significantly expand the research infrastructure needed to develop new and improved treatments and support services, and explore new ways to help finance appropriate care and supports. As with all endeavors with grand goals, achieving the agenda laid out here out will not only require substantial resources and leadership from a variety of stakeholders, but these diverse groups will have to come together with a common focus and consistent messages about what is needed to make real progress against this dreaded disease. I am extremely grateful to my colleagues on the National Academies of Sciences, Engineering, and Medicine committee that authored this report. It was both an honor and a pleasure to work with them all. I also want to express, on behalf of the whole committee, our PREPUBLICATION COPYâUncorrected Proofs
