Definition
"Infantile autism" is an outdated term for what we now call autism spectrum disorder (ASD), specifically when symptoms are noticed in early childhood. It describes the condition when children show signs of autism before the age of three. These signs often include challenges with social interaction, communication, and repetitive behaviors. Today, it's understood that autism is a spectrum. So, the term "infantile autism" is not precise enough to reflect the nuances of how autism presents in different individuals. It's more accurate to refer to it as ASD with early onset.
