Question 2

Current scientific consensus on the etiology of ASD indicates that:

Accepted Answer

ASD arises from a complex interaction of genetic and environmental factors

Answer

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

Question 3

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

Accepted Answer

Fragile X syndrome

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

Approximately 30-40%
