When a military family has a child with autism, they face all the emotions and challenges that accompany this diagnosis, compounded by the realities of military service: war, extended family separation, frequent moves, varying access to specialized healthcare, and other stressors that complicate and often work against effective treatment for children with autism. These families need help navigating these uncharted and difficult waters. This guide and its companion website are resources expressly for military families that have children with autism. Their purpose is to give each family the tools and access to information that it needs on its unique life journey through autism. More specifically, it offers: (1) An understanding of autism and related intervention and treatment; (2) Strategies for addressing the challenges of autism from the time of diagnosis through adulthood; (3) An overview of the Department of Defense (DoD) and service policies related to having a child with autism; (4) Information on autism treatment options and coverage within the military healthcare system; (5) Practical information and tools to guide your child's education; (6) Tips and advice relative to transitions such as permanent change of station (PCS) moves, new schools and more; and (7) Links to additional resources related to autism and military families [This is an update to the previous version of "Life Journey Through Autism: A Guide for Military Families."
