Autism Spectrum Disorder: Epidemiological Perspective

Autism spectrum disorders (ASD) are a group of neurodevelopmental disabilities characterized by the presence of varying degrees of deficits in social, behavioral, and communication domains of an individual’s development. These challenges are typically noticed during a child’s first 3 years of life. In recent years, autism has become a serious public health concern, yet the cause of its increasing prevalence remains unknown. According to the Centers for Disease Control and Prevention (CDC), 1 in every 44 (2.3%) 8-year-old children in the US were diagnosed with autism in 2018. This chapter aims to identify and discuss the major challenges surrounding autism care in the US, based on a comprehensive review of existing literature. It also proposes potential strategies to address these challenges. The significant problems associated with autism include: (a) Inconsistent diagnosis and referral processes, leading to delayed access to services. (b) Disparities in the availability of trained and licensed Applied Behavior Analysis (ABA) therapists. (c) Inconsistent implementation of ABA interventions across different settings. (d) Lack of support, educational services, and vocational opportunities for children transitioning into adulthood. To address these gaps in autism care, the chapter proposes the following solutions: (1) Early diagnosis and screening. (2) The use of standardized screening tools. (3) Expansion of the workforce through training initiatives. (4) Increased funding for autism research and support. (5) Ensuring equal availability of behavioral, home-based, and parent-mediated interventions. (6) Implementation science to bridge gaps in therapeutic and rehabilitative services. (7) Exploration of innovative medications. (8) Programs focusing on the socio-emotional well-being of caregivers. (9) Coordination of services and engagement of stakeholders. (10) Collaboration among healthcare providers, insurance groups, funding agencies, special education systems, and parents. (11) Creation of more opportunities for employment, higher education, and vocational training.
