What is a common feature found in all autism spectrum disorders?

A common feature found in all autism spectrum disorders is the presence of repetitive and stereotyped patterns of behavior. This characteristic can manifest in various ways, such as engaging in specific routines, using repetitive movements or gestures, or exhibiting a strong preference for sameness and consistency in their environment. These behaviors often serve as coping mechanisms for individuals on the spectrum, helping them manage anxiety or sensory overload.

While individuals with autism may display a wide range of abilities and challenges in other areas, such as communication or social interaction, the repetitive behaviors remain a consistent diagnostic criterion across the spectrum. Understanding this core feature is essential for educators, caregivers, and practitioners working with individuals with autism, as it guides interventions and supports tailored to their needs.
