Impact of prenatal life on the risk of developing epilepsy

Area of Science:

• Pediatric Neurology
• Developmental Neuroscience
• Epileptology

Background:

• Epilepsy is a chronic neurological disorder characterized by recurrent seizures.
• Prenatal brain development, especially in the third trimester, is critical for neurological health.
• Identifying early risk factors for childhood epilepsy is crucial for timely intervention.

Purpose of the Study:

• To investigate the association between prenatal factors and the risk of developing epilepsy in children.
• To examine the impact of gestational age, birth weight, maternal age, and sex on epilepsy incidence.

Main Methods:

• A case-control study involving 453 children aged 1-18 years, with and without epilepsy.
• Statistical analysis of gestational age, birth weight, maternal age, and child's sex as potential risk factors.
• Calculation of odds ratios (OR) and 95% confidence intervals (CI) to assess risk association.

Main Results:

• Children born preterm exhibited a 2.3-fold increased risk of epilepsy (OR, 2.3; 95% CI, 1.4-3.7).
• Low birth weight (<2,500 g) was associated with a 2-fold greater risk of epilepsy (OR, 2; 95% CI, 1.1-3.6).
• Female sex showed a significant association with epilepsy risk only in preterm infants (OR, 3.2; 95% CI, 1.2-8.8). Maternal age was not a significant factor.

Conclusions:

• Short gestational age and low birth weight are significant risk factors for childhood epilepsy.
• The female sex is associated with an elevated risk of epilepsy, particularly in preterm infants.
• These findings underscore the importance of prenatal care and monitoring for high-risk pregnancies.
