  1. Based on recent CDC surveillance data, approximately how many children in the US are identified with ASD?

    Answer: About 1 in 36 (approximately 2.8%)

    The CDC's 2023 ADDM report estimated ASD prevalence at 1 in 36 children (approximately 2.8%), a significant increase from prior estimates.

  2. Current scientific consensus on the etiology of ASD indicates that:

    Answer: ASD arises from a complex interaction of genetic and environmental factors

    Large-scale genetic studies and epidemiological research support a multifactorial model in which many genes and certain environmental exposures interact to increase ASD risk.

  3. Which genetic condition has among the highest rates of co-occurrence with autism spectrum disorder?

    Answer: Fragile X syndrome

    Fragile X syndrome, the most common inherited cause of intellectual disability, co-occurs with ASD in approximately 25-47% of affected males.

  4. Regarding ADHD and ASD co-occurrence, which statement is accurate?

    Answer: ADHD co-occurs with ASD in approximately 30-50% of individuals

    DSM-5 removed the prior exclusion, allowing dual diagnoses; epidemiological studies find ADHD in roughly 30-50% of individuals with ASD.

  5. Intellectual disability co-occurs with ASD in approximately what proportion of individuals?

    Answer: Approximately 30-40%

    Estimates consistently place the co-occurrence of intellectual disability in ASD at roughly 30-40%, meaning the majority of individuals with ASD have IQ scores in the average or above-average range.

  6. The reported male-to-female ratio in ASD diagnoses is approximately:

    Answer: 4:1 — four times as many males diagnosed

    Population-based studies consistently identify ASD at roughly a 4:1 male-to-female ratio, though growing evidence suggests females may be under-diagnosed due to camouflaging behaviors.

  7. Twin studies on ASD most strongly support which conclusion about heritability?

    Answer: Concordance rates are substantially higher in monozygotic than dizygotic twins

    Monozygotic twin concordance rates for ASD are considerably higher than dizygotic rates, indicating strong heritability while also leaving room for environmental contributions.
