Question: 1 / 400

What can be a consequence of maternal smoking regarding children's cognitive abilities?

Improved cognitive function

Decreased cognitive function

Maternal smoking during pregnancy has been linked to a number of negative developmental outcomes for children, particularly concerning cognitive abilities. Smoking exposes the developing fetus to harmful substances, including nicotine and carbon monoxide, which can interfere with normal brain development and function. Research has consistently shown that children exposed to maternal smoking in utero tend to have lower IQ scores, poorer academic performance, and increased risks for attention-related disorders.

The impact on cognitive function is attributed to several factors, including reduced oxygen supply to the fetus, disrupted neural growth, and potential genetic and environmental interactions that affect brain development. Thus, decreased cognitive function as a consequence of maternal smoking is well-supported by empirical evidence, reflecting the serious implications of smoking during pregnancy on a child's future cognitive capabilities.
