Which teratogen is known for causing hyperactivity, cognitive deficits, and behavioral issues?

Alcohol is recognized as a teratogen that can result in a range of developmental issues collectively known as Fetal Alcohol Spectrum Disorders (FASD). These conditions encompass a variety of symptoms, including hyperactivity, cognitive deficits, and behavioral problems.

When a pregnant individual consumes alcohol, it can disrupt fetal brain development, leading to long-lasting neurobehavioral consequences in the child. Children affected by FASD may exhibit hyperactivity, difficulties in attention, and impairments in cognitive function, which can manifest as learning disabilities and challenges in social interactions.

In contrast, while the other substances listed may have teratogenic effects, they are associated with different types of birth defects or developmental issues rather than the specific constellation of symptoms characterized by hyperactivity and behavioral problems commonly seen with alcohol exposure.
