Behavioral Medicine – Substance Use Disorders Practice Test

CNS involvement in fetal alcohol syndrome can include which of the following?

Intellectual disability and behavioral issues Enhanced motor development Increased IQ No neurological issues

Correct Answer:

Intellectual disability and behavioral issues

Explanation:

Prenatal alcohol exposure disrupts brain development, leading to neurodevelopmental problems that fall under CNS involvement. These typically appear as intellectual disability or lower cognitive functioning, along with behavioral and self-regulation difficulties due to deficits in attention, memory, and executive function. Therefore, intellectual disability and behavioral issues best reflect the CNS impact seen in fetal alcohol spectrum disorders. Options proposing enhanced motor development, increased IQ, or no neurological issues do not fit, as CNS effects are the common pattern rather than improvements or absence of problems.
