Which of the following statements about autism is true?

The correct statement is that symptoms of autism include fixed rituals and avoidance of eye contact. Autism Spectrum Disorder (ASD) is characterized by a range of symptoms that may present differently in each individual. Common symptoms include difficulties in social communication and interaction, as well as restricted and repetitive patterns of behavior. Fixed rituals, such as adhering to a strict routine or engaging in repetitive actions, and avoidance of eye contact are often observed in individuals with autism, reflecting their challenges in social interactions and preferences for predictability.

This understanding of autism emphasizes the diversity of the spectrum, where each person may exhibit a unique combination of behaviors and abilities. Recognizing these characteristics is essential for early identification and support.

The other statements do not accurately reflect the nature of autism. For instance, autism is typically diagnosed in children and adolescents, not primarily in older adults, and it can present with a range of severity, from mild to severe, rather than being confined to mild cases. Additionally, there is currently no definitive cure for autism; instead, various interventions can help manage symptoms and improve quality of life.
