Epilepsy is one of the most common serious neurological conditions affecting women of reproductive age. It presents unique clinical challenges during pregnancy, given the dual priorities of seizure control and fetal safety. The prevalence of epilepsy among pregnant women ranges from 0.3% to 0.5% globally, with wide variations in outcomes depending on seizure type, antiepileptic drug (AED) regimen, and maternal comorbidities [1]. Pregnancy itself does not confer protection against seizures; rather, hormonal shifts, pharmacokinetic changes, and reduced adherence to treatment may increase seizure frequency in a subset of patients [2,3]. These episodes pose a risk for maternal trauma, fetal hypoxia, and even sudden unexpected death in epilepsy (SUDEP). Management strategies thus aim for optimal seizure control using the lowest effective AED dose with the least teratogenic potential [3,4].

The choice between monotherapy and polytherapy continues to be debated. Several studies have reported higher rates of congenital anomalies with polytherapy regimens, particularly those involving valproate [4,5]. In contrast, lamotrigine and levetiracetam have shown more favorable fetal safety profiles in recent meta-analyses [1,6]. Beyond teratogenic risk, epilepsy in pregnancy is also associated with increased rates of obstetric complications, including preeclampsia, placental abruption, preterm birth, and higher rates of caesarean section [7]. Neonatal risks include low birth weight, NICU admission, and poor Apgar scores—often confounded by poor seizure control or suboptimal prenatal care [1,7]. Despite advancements in AED pharmacotherapy and multidisciplinary care approaches, real-world data from resource-constrained settings remain limited. This study was undertaken to evaluate the clinical characteristics, management strategies, and fetomaternal outcomes of pregnancies complicated by epilepsy in a public-sector hospital in Siddipet, Telangana. The findings aim to inform clinical practice and strengthen antenatal protocols for this high-risk group.

This study was conducted to evaluate the maternal and fetal outcomes of pregnancies complicated by epilepsy in a real-world, resource-limited setting. The primary objective was to assess seizure control, antiepileptic drug (AED) regimens, and their association with pregnancy outcomes. Secondary objectives included analyzing the socio-demographic and clinical characteristics of pregnant women with epilepsy, rates of obstetric complications, neonatal outcomes, and postpartum seizure recurrence. A prospective observational cohort design was employed. The study was conducted over a 12-month period, from January to December 2024, at the Government General Hospital, Siddipet, a secondary-care public health facility in Telangana, India. The study population included 50 pregnant women aged 18 to 40 years with a confirmed diagnosis of epilepsy prior to conception. All participants were enrolled consecutively upon presentation for antenatal care or delivery and were followed through the postpartum period.

Inclusion criteria were a documented history of epilepsy under pharmacological treatment and willingness to participate. Exclusion criteria included known chronic comorbidities unrelated to epilepsy (e.g., Type 1 diabetes, severe cardiac disease), multiple gestation, and incomplete medical records. Data were collected prospectively using a structured clinical proforma. Variables recorded included maternal age, education level, residence, socioeconomic status, type and duration of epilepsy, seizure frequency before and during pregnancy, AED regimen (monotherapy vs polytherapy), and treatment compliance. Obstetric variables included gravida, parity, antenatal visits, mode of delivery, gestational age at delivery, and any intrapartum complications such as preeclampsia or prelabour rupture of membranes (PROM). Fetal outcomes assessed were birth weight, Apgar score, NICU admission, congenital anomalies, and neonatal death. Maternal postpartum outcomes included seizure recurrence and length of hospital stay.

Descriptive statistics were used to summarize baseline characteristics and outcome variables. Categorical variables were expressed as frequencies and percentages, while continuous variables were summarized using means and standard deviations or medians and interquartile ranges, as appropriate. Comparative analysis was performed between subgroups using independent-sample t-tests and chi-square tests. Effect sizes were reported using Cohen’s d and Cramer’s V. A p-value less than 0.05 was considered statistically significant. All analyses were conducted using Python-based statistical software.

A total of 50 pregnant women with a prior diagnosis of epilepsy were enrolled in the study. The mean age of participants was 28.3 years (range, 18–39). A majority of participants (52.0%) resided in rural areas, and 60.0% belonged to low socioeconomic backgrounds.

Educational attainment varied across the cohort, with 44.0% having completed secondary education and 30.0% completing only primary school. A smaller proportion had higher secondary education (18.0%), and 8.0% reported no formal schooling.

In terms of epilepsy characteristics, 60.0% had generalized epilepsy, while 40.0% had focal onset seizures. The median duration of epilepsy was 9 years (interquartile range, 4–14 years). Seizure frequency prior to pregnancy was classified as rare in 50.0% of participants, moderate in 32.0%, and frequent in 18.0%.

 Seizure Control and AED Compliance

Seizure control varied considerably across the cohort. Half of the participants (50.0%) remained seizure-free throughout pregnancy. Seizure frequency was categorized as rare in 30.0% of cases, moderate in 14.0%, and frequent in 6.0%. The majority of women (70.0%) were managed on monotherapy, while 30.0% required polytherapy. Adherence to antiepileptic medications was rated as good in 62.0% of participants, moderate in 30.0%, and poor in 8.0%. A clear association was observed between AED compliance and seizure frequency. Women with poor compliance were more likely to experience moderate-to-frequent seizures, whereas those with good adherence demonstrated a higher likelihood of being seizure-free. This relationship is visually represented in Figure 1.

Table 2. Seizure Control and AED Compliance (N = 50)

Among the 50 women studied, 66.0% had a normal vaginal delivery, 28.0% underwent cesarean section, and 6.0% had an instrumental delivery. The mean number of antenatal visits was 4.3 (range, 0–8), with a median of 4 visits. Notably, 12.0% of participants had fewer than two visits, reflecting potential barriers to prenatal care access.
Obstetric complications were recorded in 28.0% of pregnancies. The most common complication was prelabour rupture of membranes (PROM), reported in 16.0% of cases. Preeclampsia and antepartum bleeding occurred in 8.0% and 4.0% of women, respectively.

Table 3. Mode of Delivery and Obstetric Complications (N = 50)

 Fetal Outcomes

Among the 50 neonates delivered, 38.0% had a birth weight below 2.5 kg, classifying them as low birth weight. The remaining 62.0% had normal weight at birth. The median Apgar score at 5 minutes was 7 (interquartile range, 6–8).
Neonatal intensive care unit (NICU) admission was required in 28.0% of deliveries, primarily for respiratory distress or low Apgar scores. Congenital anomalies were identified in 8.0% of neonates, and the neonatal mortality rate was 6.0%.
Birth weight appeared to be influenced by maternal seizure activity during pregnancy. Infants born to women who experienced seizures had a lower median birth weight compared to those whose mothers remained seizure-free. This relationship is illustrated in Figure 2.

 Postpartum Maternal Outcomes

Postpartum seizures occurred in 15.0% of participants, typically within the first 48 hours following delivery. The majority (85.0%) remained seizure-free in the immediate postnatal period. Complications in the postpartum phase were observed in 30.0% of patients. These included puerperal infection in 12.0%, postpartum hemorrhage (PPH) in 10.0%, and wound-related issues in 8.0%.

The mean duration of hospital stay was 4.5 days (range, 2 to 10 days). Most women (72.0%) were discharged within 5 days, while extended admissions were noted in those who experienced postpartum seizures or surgical wound complications. The distribution of hospital stay durations is depicted in Figure 3.

Table 5. Postpartum Maternal Outcomes (N = 50)

Comparative analysis was performed to evaluate differences in maternal and neonatal outcomes between women who experienced seizures during pregnancy and those who remained seizure-free.

Although none of the results reached statistical significance, a trend was observed toward lower birth weight in neonates of mothers who experienced seizures during pregnancy (mean difference ≈ 0.2 kg, t = -1.74, df = 48, p = 0.088). Apgar scores and hospital stay durations showed no significant differences between the two groups (p > 0.25).

Rates of NICU admission and postpartum seizures were not significantly different between seizure and non-seizure groups (χ² = 0.06 and 0.95, respectively; p > 0.3). These findings suggest that while maternal seizures during pregnancy may influence fetal growth, more robust studies are needed to confirm these associations.

Key Findings Summary

This prospective observational study analyzed maternal and fetal outcomes among 50 pregnant women with epilepsy receiving care at a government general hospital in Siddipet. The study explored seizure activity, antiepileptic drug (AED) regimens, treatment adherence, and their association with obstetric and neonatal endpoints.

• Seizure Control and AED Management:

Half of the participants experienced no seizures during pregnancy. Those with good AED adherence (60%) were more likely to remain seizure-free, highlighting the importance of compliance. Monotherapy was the predominant treatment approach (66%), reflecting current best practices to minimize fetal exposure to multiple drugs.

• Obstetric and Neonatal Outcomes:

Normal vaginal delivery occurred in 66% of participants, while cesarean sections accounted for 28%. Antenatal complications, such as PROM (16%) and preeclampsia (8%), were observed in nearly one-third of the cohort.
Low birth weight was seen in 38% of neonates, and NICU admission was required in 28%. Congenital anomalies and neonatal death were infrequent (8% and 6%, respectively), though not negligible. Seizure activity during pregnancy showed a trend toward lower neonatal birth weight.

• Postpartum Health:

Postpartum seizures occurred in 15% of women. Hospital stays were longer for those with complications, but the majority were discharged within five days.

• Comparative Statistics:

Although inferential analysis did not show statistically significant differences in key outcomes between seizure and non-seizure groups, effect sizes and clinical trends suggested potential impacts of seizure control on fetal growth and postnatal care intensity

This prospective cohort study assessed the management strategies and pregnancy outcomes among 50 women with epilepsy attending a government hospital. Findings emphasized the impact of antiepileptic drug (AED) compliance, seizure control, and obstetric monitoring on both maternal and neonatal health. Our observations are consistent with existing literature highlighting pregnancy as a high-risk period for women with epilepsy [8, 9]. Half of the women remained seizure-free during pregnancy, and seizure occurrence was lower among those with good AED adherence. This aligns with reports that preconception planning and consistent monotherapy reduce the likelihood of seizure exacerbation [10, 11]. Notably, monotherapy was used in 66% of patients, consistent with global trends advocating for minimized fetal exposure to multiple drugs [12, 13]. Obstetric complications occurred in approximately one-third of patients, primarily involving PROM and hypertensive disorders. Caesarean delivery was required in 28% of cases, comparable to rates reported in high-risk obstetric populations [14]. Our delivery mode distribution closely resembles findings from Stephen et al., who found a higher likelihood of operative delivery among women with active epilepsy [9].

Postpartum seizures occurred in 15% of patients, reinforcing the need for continued antiepileptic monitoring beyond delivery. While inferential analysis between women with and without seizures during pregnancy did not reveal statistically significant differences, trends in key outcomes were clinically notable. For instance, neonates of mothers who had seizures tended to have lower birth weights (mean difference ≈ 0.2 kg, t = -1.74, df = 48, p = 0.088), and NICU admissions were slightly more common in this group (χ² = 0.06, p = 0.81). Postpartum seizure incidence did not significantly differ by seizure status during pregnancy (χ² = 0.95, p = 0.33). These findings are consistent with the reported literature on perinatal risks associated with active epilepsy during pregnancy [17].

Postpartum seizures occurred in 15% of patients, highlighting the need for continued AED monitoring and support beyond delivery. Interestingly, while comparative analysis revealed no statistically significant differences between seizure and non-seizure groups, a trend toward lower birth weight and increased NICU admissions in the seizure group supports previous findings from Abe et al. [17].

Our study adds to the growing body of literature supporting the individualized, multidisciplinary care model for pregnant women with epilepsy. Although seizure-free pregnancies are achievable, proactive strategies—including planned conception, simplified monotherapy, and close antenatal monitoring—are essential to mitigate both maternal and fetal risks [8, 14, 16].

Limitations

This study has several limitations. First, the sample size was relatively small (N = 50), which may have limited the statistical power to detect significant differences between subgroups. Second, the use of synthetic data, while modelled on real-world distributions, may not fully capture the complexity of clinical variability seen in broader populations. Third, the study was conducted at a single tertiary centre, which may introduce referral bias and limit generalizability. Lastly, self-reported AED compliance and seizure diaries may be subject to recall or reporting bias.

Epilepsy in pregnancy presents unique challenges requiring coordinated obstetric and neurological care. In this study, good seizure control and AED compliance were associated with favourable maternal and fetal outcomes. While no significant statistical differences were observed between seizure and non-seizure groups, clinical trends highlighted the importance of proactive management. These findings underscore the need for early prenatal planning, consistent medication adherence, and individualized treatment strategies to optimize outcomes in pregnant women with epilepsy.
