Evidence for behavioral teratogenicity in humans.

Area of Science:

• Behavioral teratology
• Developmental toxicology
• Neuroscience

Background:

• Establishing a link between prenatal exposure to exogenous agents and offspring neurobehavioral disorders is fundamental to behavioral teratology.
• While widely accepted, some toxicologists remain unconvinced of this causal relationship.

Purpose of the Study:

• To review the accumulated evidence demonstrating that prenatal exposure to various agents induces behavioral disorders in human infants.
• To reinforce the scientific basis of behavioral teratology by presenting established findings.

Main Methods:

• Literature review of existing studies.
• Synthesis of evidence on drugs and environmental/industrial agents.
• Focus on human infant behavioral outcomes.

Main Results:

• Prenatal exposure to numerous drugs is linked to behavioral disorders in offspring.
• Environmental and industrial agents also contribute to infant behavioral deficits following prenatal exposure.
• The evidence supports a significant impact of exogenous agents on prenatal development and subsequent behavior.

Conclusions:

• The evidence strongly supports the principle that prenatal exposure to exogenous agents causes neurobehavioral disorders in offspring.
• This review consolidates findings crucial for advancing the field of behavioral teratology.
• Understanding these risks is vital for public health and preventative strategies.
