Final answer:
Autism spectrum disorder (ASD) typically appears during the first 3 years of life, and this statement is a fact. The disorder shows a higher prevalence among males, and although signs are usually early, diagnoses can vary based on symptom severity.
Step-by-step explanation:
Fact or Myth: Does ASD typically appear during the first 3 years of life? The correct answer is A) Fact. Autism spectrum disorder (ASD) is a neurodevelopmental disorder that typically manifests during the first few years of a child's life, with many parents noticing signs within the first 2 years. It is characterized by challenges with social interaction, communication, and by restricted and repetitive behavior. The prevalence of ASD has been increasing, with current estimates positing that 1 in 88 children will be diagnosed with the condition. Moreover, it is more common in males than females, with a ratio of 4:1. While signs of ASD usually appear early in development, the severity can differ significantly among individuals, and certain cases may be identified later due to subtler symptom presentation.
