Building Paths: Maternal Perceptions of Autism Spectrum Disorder in the SUS is a work that delves into the universe of mothers of people with Autism Spectrum Disorder (ASD), revealing their experiences, challenges and overcomings in the context of the Unified Health System (SUS). This book offers a sensitive and in-depth look at atypical motherhood, addressing the barriers faced in accessing diagnoses, therapies and adequate support, as well as the strategies that these mothers build to ensure the development and well-being of their children. Through stories and reflections, the book discusses the emotional, social and structural complexities that permeate care for ASD, highlighting how Brazilian public health directly impacts the trajectories of these families. It also explores issues such as the impact of the diagnosis on the mothers' lives, the support they receive (or lack of) and the specific demands that emerge from this experience. More than a record of experiences, this book is an inspiration for professionals, managers and researchers seeking to better understand the needs of families of people with ASD.
