Every year on April 2, World Autism Awareness Day is observed. This day raises awareness about autism spectrum disorder (ASD) which is a developmental brain disorder which impacts how a person perceives and socializes with others. This condition may cause problems in social interaction and communication. The condition may also include limited and repetitive patterns of behavior. Origin of World Autism DayIt was started in 2007, when the United Nations General Assembly designated 2 April as World Autism Awareness Day. The UN worked to promote the full realization of human rights and fundamental freedoms for autistic individuals and ensured their equal participation in society. In fact, over the years, progress has been made and driven in large by autistic advocates who have worked tirelessly to bring the lived experiences of autistic individuals to the forefront of global discussions. The 2007 General Assembly resolution also highlighted the need to raise public awareness of autism. Theme of World Autism DayThe theme for 2025 is "Advancing Neurodiversity and the UN Sustainable Development Goals (SDGs)". This goal highlights the intersection between neurodiversity and global sustainability efforts and showcases how inclusive policies and practices can drive positive change for autistic individuals worldwide and contribute to the achievement of SDG. This year's theme and discussion also explores at the role of neurodiversity in shaping policies that promote accessibility, equality, and innovation across multiple sectors. Significance of World Autism DayThe day aims to foster a better understanding of autism and the importance of early diagnosis and intervention. The day also tries to promote awareness and acceptance and create a more inclusive and supportive environment for individuals with autism. What Is Autism?As per the American Psychiatric Association, ASD is a complex developmental condition involving persistent challenges with social communication, restricted interests and repetitive behavior. While autism is considered a lifelong condition, the need for services and supports because of these challenges varies among individuals with autism. As per the Centers for Disease Control and Prevention, an estimated one in 36 children have been identified with ASD.
