Autism spectrum disorder (ASD) is a complex developmental condition that affects individuals in various ways. Understanding autism and raising awareness about it is crucial to creating a more inclusive and supportive society.  World Autism Awareness Day, observed on April 2, serves as a reminder of understanding and supporting individuals with autism. Let's delve deeper into the intricacies of autism and why awareness about it is important.  What is Autism? Autism, also known as autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental variation in brain functioning, influencing communication, interaction, and learning patterns. People with autism may have difficulty understanding social cues, expressing themselves verbally or nonverbally, and engaging in repetitive behaviours or interests.  Autism is a spectrum disorder, meaning that it affects each individual differently, ranging from mild to severe. It is crucial to understand that autism is not a sickness; it is a lifelong condition present from birth. Various therapies are available to assist individuals in coping with challenges and leading fulfilling lives.

Scientists have identified rare gene mutations and common genetic variations linked to autism. Emerging research focuses on the interaction between genetic predisposition and environmental influences.  For instance, maternal exposure to harmful substances during pregnancy could contribute to genetic mutations associated with autism. The disorder's multifaceted nature highlights the need for further investigation.
