Abstract/Preface
Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by persistent differences in social communication and interaction, alongside restricted and repetitive patterns of behavior, interests, or activities. The term “spectrum” reflects the wide variation in strengths, challenges, and support needs among individuals. Over recent decades, increased awareness, improved diagnostic practices, and expanded research have reshaped the clinical and societal understanding of ASD across the lifespan. This chapter provides a comprehensive overview of ASD, including its historical background, epidemiology, etiology, clinical features, assessment, interventions, educational and psychosocial considerations, and emerging directions in research and practice. Emphasis is placed on neurodiversity-informed approaches, early identification, family-centered care, and the importance of individualized support systems. Future directions highlight advances in genetics, neuroscience, digital health technologies, and inclusive policy frameworks aimed at enhancing the quality of life for autistic individuals.
