Given the distinctive characteristics of both epilepsy and antiepileptic drugs (AEDs), therapeutic drug monitoring (TDM) can make a significant contribution to the field of epilepsy. The measurement and interpretation of serum drug concentrations can be of benefit in the treatment of uncontrollable seizures and in cases of clinical toxicity; it can aid in the individualization of therapy and in adjusting for variable or nonlinear pharmacokinetics; and can be useful in special populations such as pregnancy. This review examines the potential for TDM of newer AEDs such as eslicarbazepine acetate, felbamate, gabapentin, lacosamide, lamotrigine, levetiracetam, perampanel, pregabalin, rufinamide, retigabine, stiripentol, tiagabine, topiramate, vigabatrin, and zonisamide...

OBJECTIVE: To investigate whether prepregnancy overweight in women with epilepsy increases their risk for complications during pregnancy and delivery. METHODS: This study is based on The Norwegian Mother and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. A diagnosis of epilepsy was reported in 706 pregnancies. Overweight was defined as body mass index ≥ 25 prepregnancy. Overweight women with epilepsy (n = 259) were compared to normal-weight women with epilepsy (n = 416), and to women without epilepsy with and without overweight (n = 30,516 and n = 67,977, respectively)...

INTRODUCTION: Prenatal antiepileptic drug (AED) exposure is associated with an increased risk of cognitive impairment and autism spectrum disorders detected mainly at the age of two to six years. We examined whether the developmental aberrations associated with prenatal AED exposure could be detected already in infancy and whether effects on visual attention can be observed at this early age. MATERIAL AND METHODS: We compared a prospective cohort of infants with in utero exposure to AED (n=56) with infants without drug exposures (n=62)...

In the US, more than one million women with epilepsy are of childbearing age and have over 20,000 babies each year. Patients with epilepsy who become pregnant are at risk of complications, including changes in seizure frequency, maternal morbidity and mortality, and congenital anomalies due to antiepileptic drug exposure. Appropriate management of epilepsy during pregnancy may involve frequent monitoring of antiepileptic drug serum concentrations, potential preconception switching of antiepileptic medications, making dose adjustments, minimizing peak drug concentration with more frequent dosing, and avoiding potentially teratogenic medications...

Epilepsy is one of the few neurologic disorders that requires a constant treatment during pregnancy. Epilepsy affects 0.3-0.8% of pregnant women. Prescription of antiepileptic drugs (AEDs) to pregnant women with epilepsy requires monitoring and maintaining a balance between limiting seizures and decreasing fetal exposure to the potential teratogenic effects. AEDs are also commonly used for psychiatric disorders, pain disorders, and migraines. The types of malformations that can result in fetuses exposed to AEDs include minor anomalies, major congenital malformations, intrauterine growth retardation, cognitive dysfunction, low IQ, microcephaly, and infant mortality...

OBJECTIVE: Effective contraception enables women with epilepsy (WWE) to plan their pregnancies and improve outcomes for themselves and their children. Although popular among all women, complex drug interactions limit the efficacy and safety of oral contraceptives (OCs) for WWE. We sought to explore the safety, acceptability, and pharmacokinetic impact of a progestin-containing intrauterine device (IUD) in WWE. METHODS: We enrolled 20 women with well-controlled epilepsy and a stable antiepileptic drug (AED) regimen and who were initiating a progestin-containing IUD (levonorgestrel 52 mg) in a prospective, observational study...

In the vast majority of women with epilepsy, no complications occur during pregnancy. Important for that is early, preconceptional counseling and close surveillance during pregnancy. The aim should be to maintain the best possible seizure control without occurrence of generalized tonic-clonic seizures while using antiepileptic drugs and with the lowest possible risk of malformations. The warnings for the prescription of valproic acid in women of reproductive age were tightened because of the dose-dependent increase in the malformation rate and other risks, especially regarding adverse effects on childhood cognitive development...

OBJECTIVE: To investigate the effects of prenatal exposure to monotherapy levetiracetam, topiramate, and valproate on child cognitive functioning. METHODS: This was a cross-sectional observational study. Children exposed to monotherapy levetiracetam (n = 42), topiramate (n = 27), or valproate (n = 47) and a group of children born to women who had untreated epilepsy (n = 55) were enrolled retrospectively from the UK Epilepsy and Pregnancy Register. Assessor-blinded neuropsychological assessments were conducted between 5 and 9 years of age...

BACKGROUND: Some recent studies have found an association between foetal malformations in earlier antiepileptic drug (AED)-exposed pregnancies and an increased hazard of such malformations in subsequent pregnancies. We investigated this matter further, and also considered the possible role of spontaneous abortions in previous pregnancies, in this situation. METHODS: Analysis of foetal malformation data for current and previous pregnancies in women taking AEDs and women with untreated epilepsy in the Australian Register of Antiepileptic Drugs in Pregnancy (APR) from 1999 to late 2014...

Although prenatal exposure to antiepileptic drugs (AEDs) is known to impart relatively higher risks of major congenital malformations, prospective studies have provided refined data that allow us to differentiate the risks of different types and doses of AEDs. As the number of AED prescriptions has dramatically increased in reproductive-aged women with a variety of neuropsychiatric indications, the evolving concepts learned from studies in women with epilepsy can be applied to a much larger group of pregnant women to improve child outcomes while maintaining maternal disease control...

The usage of drugs during pregnancy affect the fetus and the newborn. In this report, we present findings from a newborn baby, whose mother was epileptic, and was under the treatment of valproic acid and carbamazepine during pregnancy. We have found symptoms of withdrawal syndrome, hyponatremia and feeding problem, which was most probably related to exposure to the mentioned drugs. We have also diagnosed hypomagnesaemia and atrial septal defect 4 milimeters in diameter. There are already many reports about the side effects of valproic acid and carbamazepine usage during pregnancy...

INTRODUCTION: Antiepileptic drugs (AEDs) are teratogens and confer a risk of congenital malformation. The estimated prevalence of major congenital malformations such as cardiac defects, facial clefts, hypospadias, and neural tube defects in epileptic women is 4-10 %, which represents a two- to fourfold increase in pregnant women compared to the general population. However, there are no clear data for newer drugs. Lacosamide (LCM), a novel AED, is the first of the third-generation AEDs to be approved as adjunctive therapy for the treatment of partial-onset seizures...

Neurocysticercosis (NCC) is a parasitic infection with the larvae of Taenia solium from contaminated pork. It is a leading cause of seizures in the developing world. Symptoms may be secondary to live or degenerating cysts, or previous infection causing calcification or gliosis. Diagnosis is based on clinical presentation, radiological confirmation of intracranial lesions and immunological testing. Management involves symptom control with antiepileptics and antiparasitic agents. Few cases have been described of maternal NCC during pregnancy...

INTRODUCTION: The prescription pattern of antiepileptic drugs (AEDs) during pregnancy is changing but to what extent this is occurring in Spain remains unknown. The efficacy of newer drugs for controlling seizures is a key issue and may have changed over the years as doctors gained familiarity with these drugs during pregnancy. To assess these 2 topics, we report the results from the Spanish EURAP register gathered over a 12-year period. MATERIAL AND METHODS: After signing informed consent forms, patients were included in the register and evaluated at onset of pregnancy, at the end of the second and third trimesters, after delivery, and one year after delivery...
