World Autism Awareness Day: 2nd April 2025

Did you know that this year marks the 18th World Autism Awareness Day? It's a global effort to encourage countries around the world to raise awareness about autism and uphold the human rights of autistic individuals.

The United Nations describes autism as a lifelong neurological condition that manifests early in childhood. It doesn’t discriminate—it affects people of all genders, races, and backgrounds. Autism is often characterized by unique ways of interacting socially, learning, and communicating, as well as specific interests, a preference for routines, and differences in sensory processing. The autistic spectrum refers to a range of characteristics in neurological variation that may require appropriate support, accommodation, and acceptance to ensure equal opportunity and full participation in societal life.

Globally, about 1 in 100 people are autistic, according to the World Health Organization. However, more recent studies suggest the numbers may be higher. For example, the Centers for Disease Control and Prevention in the U.S. reported in 2023 that autism affects 1 in 45 people there, with similar findings from UCL’s research in the UK.

Even after decades of research, we still don’t have all the answers. Some outdated and harmful theories—like the "Refrigerator Mother" theory or linking autism to childhood schizophrenia or extreme male brain traits—have been debunked. Today, researchers focus on genetic, environmental, and prenatal factors, but there’s still a lot to learn.
