Understanding Autism Signs
Autism Spectrum Disorder (ASD) is a developmental condition that affects how a person communicates, interacts socially, and processes the world around them. Because autism is a spectrum, the signs and symptoms can look very different from one individual to another.
Recognizing these signs early, whether in a toddler or an adult, is crucial. It can pave the way for families to access the proper support, therapies, and resources, significantly improving the quality of life. This guide meticulously breaks down autism symptoms by age group, gender, and life stage.
