Antiepileptic drug therapy and congenital defects

Area of Science:

• Obstetrics and Gynecology
• Neurology
• Teratology

Background:

• Epilepsy affects pregnant women, necessitating continuous antiepileptic drug (AED) therapy for maternal and fetal well-being.
• AEDs are crucial for managing seizures but may pose risks for congenital malformations in offspring.
• Understanding the teratogenic role of AEDs is vital for risk mitigation.

Purpose of the Study:

• To review congenital malformations in the offspring of epileptic mothers.
• To elucidate the etiologic role and mechanisms of action of AEDs in causing birth defects.
• To propose guidelines for optimal preconceptional therapy to prevent defects.

Main Methods:

• Literature review of studies on congenital malformations in offspring of epileptic mothers.
• Analysis of the role of antiepileptic drugs in teratogenesis.
• Synthesis of current knowledge to develop therapeutic guidelines.

Main Results:

• Congenital malformations, both morphologic and functional, are observed in offspring of epileptic mothers.
• Antiepileptic drugs are identified as a primary factor in the etiology of these defects.
• A proportion of these defects are preventable with optimal therapy initiated preconceptually.

Conclusions:

• Optimal management of epilepsy during pregnancy, starting preconceptually, can significantly reduce the incidence of congenital malformations.
• Further research into AED mechanisms is needed to refine preventive strategies.
• Guidelines for preconceptional counseling and therapy are essential for improving outcomes.
