Purpose:
Epilepsy is the most common neurological disorder requiring medical treatment during pregnancy. However, very few studies are specially dedicated to pregnant women with refractory epilepsy. This study was carried out with the aim of describing obstetrical and neurological outcomes of pregnant women with refractory epilepsy in Brazil.
Methods:
Pregnant women with refractory epilepsy were enrolled in longitudinal cohort study between January 2005 and January 2018. They were regularly followed by a neurologist until the end of pregnancy. Neurological outcomes included seizure control, status epilepticus and adherence to antiepileptic medications. Obstetrical outcomes included major congenital malformations and obstetrical complications.
Results:
A total of eighty two patients with a mean age of 24.5 ± 5.5 were included in our study. A significant number of women experienced an increase in seizure frequency and the prevalence of status epilepticus was 8.5%. More than half were non-adherent to antiepileptic drugs. Most of patients required treatment changes during pregnancy, in dose and/or in number of antiepileptic drugs. Cesarean section was the preferred way of delivery and five cases of major congenital malformations were detected. Obstetrical complications were significantly associated with polytherapy, multiple comorbidities, poor adherence to treatment and seizure deterioration during pregnancy (p < 0.05).
Conclusions:
Women with refractory epilepsy can have a significant risk of obstetric and neurological complications during pregnancy. Treatment of refractory epilepsy in pregnancy is a real challenge for neurologists.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
