Global burden and management of women with epilepsy in pregnancy: A modeling study.

BACKGROUND

Most pregnant women with epilepsy do not receive proper medical care, which creates a special burden worldwide. We aimed to qualify this special global burden and assess the impact of different clinical management strategies to reduce it.

METHODS

The data used in this study were extracted from articles published between 2005 and 2022. We calculated the economic costs associated with major burdens experienced by pregnant women with epilepsy. We developed a microsimulation model to estimate the different effects of various interventions and their combinations as integrated strategies for pregnant women with epilepsy and related burden reduction. We also compared the regional differences in disease burden and interventions.

FINDINGS: The total economic burden for pregnant women with epilepsy is estimated to reach $1.8 billion globally annually, which is more than three times the burden for epilepsy alone. Folic acid supplementation is projected to be the most effective intervention, with a 9.1% reduction in major congenital malformations, a 14.9% reduction in autism spectrum disorder, and a 10.8% reduction in offspring-related economic burden globally annually. Integrated strategies are associated with a reduced economic burden of up to $37.7 million annually globally. Folic acid supplementation is the most effective intervention in high- and upper-middle-income countries, whereas changes in antiseizure medication prescriptions are more effective in lower-middle- and low-income countries.

CONCLUSION

This study highlights the huge burden for pregnant women with epilepsy and actions that must be taken to improve their quality of life.
