Abstract
Epilepsy is a neurodevelopmental disorder that affects millions of adults and children. Several different types of seizures, ranging from generalized which affect both sides of the brain to focal seizures that are rooted in one location of the brain. In addition to the physical impact of epilepsy, there are many emotional and identity consequences of living with epilepsy. An area that is not yet explored is the impact of epilepsy on the lives of women of color. In this paper, we fill this gap by exploring the experiences of two women of color who have had epilepsy beginning in early childhood through motherhood. One of the women is Mexican-American and an early career faculty in social work. The other identifies as a Chinese immigrant doctoral student in disability studies. Together, these stories bring to the literature voices that have not been actively engaged by epilepsy research or academia. We use a duoethnographic approach in this work given that this method provides an opportunity to explore identity and intersectionality and juxtapose our narratives surrounding epilepsy. By applying disability critical race theory (DisCrit) to our narratives, we identified how fluctuating epileptic symptoms, gender, and culture, interact with the layers of our epileptic identities. Furthermore, we discuss how our experiences with epilepsy exposes the lack of accommodative efforts in both the healthcare and education systems for individuals with invisible neurodevelopmental disabilities. This duoethnography has important implications for engaging youth with epilepsy and other invisible disabilities. By showcasing our journey of "coming to terms" with epilepsy, our dialog provides insights into how to support youth in building a positive disability identity. Our experiences in academia set up a basis to discuss accommodations for students with epilepsy and other invisible disabilities.

Abstract
Epilepsy is a common disorder and exposure to antiepileptic drugs during pregnancy increases the risk of teratogenicity. Older AEDs such as valproate and phenobarbital are associated with a higher risk of major malformations in the fetus than newer AEDs like lamotrigine and levetiracetam. Exposure to valproic acid during first trimester can result in fetal valproate syndrome (FVS), comprising typical facial features, developmental delay, and a variety of malformations such as neural tube defects, cardiac and genitourinary malformations, and limb defects. We are presenting an Indian case of FVS with major limb defects.

Abstract
PURPOSE Women with epilepsy (WWE), of all ages, have much to consider if their care is to be optimised and they are not to be denied the choices open to those without epilepsy. At no time is this more critical than during their child-bearing years when treatment decisions are complex. METHODS In this article we will provide a personal commentary and review of the pertinent literature on how the management of WWE of childbearing years has changed over the last 25 years. As well as reflecting on the state of knowledge at the start of the 1990s and the approach to managing WWE at this time, we will demonstrate that in addition to much more information now being available that there has also been an attempt to standardise how WWE should be managed. RESULTS As a means of achieving this increase in knowledge and standardisation of care, we argue that the various pregnancy registries have played a significant part in these positive developments. As vehicles for collecting clinically relevant data, they have provided information that has helped empower women and their health care providers to make sound clinical decisions, as well as highlighting the difficulties and unknowns. CONCLUSIONS Still being active the pregnancy registries maintain a continued focus on the relevant issues relating to WWE.

Abstract
OBJECTIVE This paper reveals the studies of carbamazepine monitoring in the manifestation of side effects during clinical use. It is important to realize that these ranges are derived statistically, with most patients who have high levels suffering side effects and some with poor control having low levels. Broadly, the newer agents have advantages of lower risk of side effects and less drug interaction. At the presence they are more expensive than the, than "older" agents. Current recommendations and practice are to use newer agents as second line drugs, although in some countries there are gaining favour as potential first line agents. METHODS In the study 91 patients with epilepsy were involved from which 53 or 58.2% were female and 38 or 41.8% were male with no great significant difference between two genders (X(2)=2.47, P=0.116). However, according to the study results female patients had slightly greater prevalence of epilepsy than man. Average age of epileptic patients was 23.2 years (SD ± 16.4 years), in the range 1-66 years. Patient distribution was present within all age-groups, but 59.4% of all patients were up to 20 years old. The highest prevalence of epilepsy was in the group age 6-15 years old: 33.0%. There were also children 1 - 5 years old with 7 or 7.7% of the patients, and the patients older than 60 years with 4 or 4.4% of the patients. Patient distribution according to the age and gender results with no female patient over 60 year old and more female patients in the age group 1-5 years. However statistically this did not produce a highly significant difference (T-test= 0.72, P=0.437) between average age according to the gender. The average age of the female gender was 22.1 year (SD ± 14.2 years), with the range 2-55 years, while the average age of the male patients was 24.6 year (SD ±19.2 years), with the range 1-66 years. CONCLUSION Unwanted side effects of antiepileptic drugs analyzed in the study are frequent, but not so severe as to be life threatening. Treatment of epilepsy with these three drugs (carbamazepine, ac.valproic and phenobarbitone) would be the first choice of treatment, with the best safety and efficacy. Application of this therapy is rarely compromised because of the appearance of unwanted side effects. Replacement or termination of therapy may be applied if actual therapy is not adequate for the management of epileptic attacks.

Abstract
Antenatal use of anticonvulsant valproic acid can result in a well-recognized cluster of facial dysmorphism, congenital anomalies and neurodevelopmental retardation. In this report, we describe a case with typical features of fetal valproate syndrome (FVS). A 26-year-old female with epilepsy controlled on sodium valproate 800 mg/day since 3 years, gave birth to a male child with characteristic features of FVS. She also had 3 spontaneous first-trimester abortions during those 3 years. Sodium valproate, a widely used anticonvulsant and mood regulator, is a well-recognized teratogen that can result in facial dysmorphism, craniosynostosis, neural tube defects, and neurodevelopmental retardation. Therefore, we strongly recommend avoidance of valproic acid and supplementation of folic acid during pregnancy.

Abstract
For women with epilepsy (WWE), pregnancy is complicated by considerations such as the potential teratogenicity of antiepileptic drugs (AEDs) versus the risks of having seizures during pregnancy. However, qualitative research suggests that many WWE remain uninformed about the risks associated with epilepsy and pregnancy and may, therefore, be making uninformed decisions about their families. The objectives of this review were to determine the level of patient knowledge, their informational needs, and whether these needs concerning pregnancy and childbirth issues are met among WWE. Electronic databases searched were PsycINFO, MEDLINE, Embase, CINAHL, and Web of Science. Studies were included if they used quantitative methods to survey WWE aged 16years or older about their knowledge, access to information, or informational needs specifically regarding epilepsy and pregnancy. Twelve studies were identified and assessed for research standards using the Quality Index. Overall Quality Index score was only 7.1 out of 14, indicating significant design limitations of many included studies, including highly selective sampling methods and the use of unvalidated outcome measures. There was a paucity of studies investigating specific areas of women's knowledge and information needs. Overall, WWE reported adequate awareness, but limited knowledge, of key issues regarding pregnancy and childbirth. Across studies, many women reported not receiving information about these issues. Evidence suggested that many WWE wanted to receive more information - particularly about the risks of AEDs for their offspring - well in advance of choosing an AED or planning pregnancy. Women aged under 35years wanted the most information. Preconception counseling received by many WWE appears insufficient, risking uninformed decision-making about pregnancy. Further research is needed to investigate the barriers that WWE face in accessing, receiving, and retaining appropriate information.

Abstract
Pregnant women with epilepsy have to balance maternal and fetal risks associated with uncontrolled seizures against the potential teratogenic effects from antiepileptic drugs (AEDs). Carbamazepine (CBZ) is among the four most commonly used AEDs for treatment of pregnant epileptic women. We previously reported that new-born children had a decreased head circumference after in utero CBZ exposure. This study investigates how prenatal exposure of CBZ influences the number of neurons in new-born and young mouse hippocampus, amygdala and cortex cerebri. Clinical studies describe inconclusive results on if prenatal CBZ treatment influences cognition. Here we investigate this issue in mice using two well characterized cognitive tasks, the passive avoidance test and the Morris water maze test. Prenatal exposure of CBZ reduced the number of neurons (NeuN-immunoreactive cells) in the new-born mouse hippocampus with 50% compared to non-exposed mice. A reduction of neurons (20%) in hippocampus was still observed when the animals were 5 weeks old. These mice also displayed a 25% reduction of neurons in cortex cerebri. Prenatal CBZ treatment did not significantly impair learning and memory measured in the passive avoidance test and in the Morris water maze. However, these mice displayed a higher degree of thigmotaxic behaviour than the control mice. The body weight of prenatally CBZ exposed five-week old mice were lower compared to control mice not exposed to CBZ (p = 0.001). In conclusion, prenatal exposure to CBZ reduces the number of neurons dramatically in areas important for cognition such as hippocampus and cortex, without severe impairments on learning and memory. These results are in line with some clinical studies, reporting that CBZ has minor negative effects on cognition. The challenge for future studies are to segment out what possible effects a reduction of neurons could have on different types of cognition, like intellectual ability and social interaction.

Abstract
We present a case of a woman who used topiramate (100 mg) and oxcarbazepine (300 mg) continuously during pregnancy. Multiple fetal anomalies including limp defects of the lower extremities, pericardiac fluid collection, cardiomegaly, cleft lip and palate, absent right kidney, and dysplastic left kidney were found by ultrasonography. Labor was induced and anomalies were confirmed by autopsy. The malformation rate after exposure to oxcarbazepine in utero as a monotherapy was calculated to be 2.4%, which is compatible with the malformation rate seen in the general population. Topiramate is teratogenic in mice, rats, and rabbits, but there are very few reports about its teratogenicity in humans.

Abstract
Reproductive endocrine dysfunction in women with epilepsy is an important issue, and in recent years there is growing evidence to support the effect on sex hormones of both epilepsy per se and various antiepileptic drugs (AEDs). Focal epileptic discharges from the temporal lobe may have a direct influence on the function of the hypothalamic-pituitary axis, thereby altering the release of sex steroid hormones. The role of laterality and severity of epilepsy is still conflicting. The use of the liver enzyme-inducing AEDs--such as phenobarbital, phenytoin, and carbamazepine--can increase serum sex hormone-binding globulin concentrations, leading to diminished bioactivity of testosterone (T) and estradiol. Valproic acid, an enzyme inhibitor, has been associated with the occurrence of reproductive endocrine disorders characterized by high serum T, free androgen index, androstenedione, dehydroepiandrosterone sulfate concentrations, and with polycystic changes in ovaries and menstrual disorders. A better understanding of the effects of AEDs on sex hormones is key to selecting the appropriate AEDs and is crucial for reproductive health in female patients.

Abstract
Fetal valproate syndrome (FVS) results from prenatal exposure to valproic acid. It is characterized by a distinctive facial appearance, a cluster of minor and major anomalies and central nervous system dysfunction. We describe a 2-month-old male infant with the typical dysmorphic features characteristic of FVS. He had a persistent left superior vena cava draining into a dilated coronary sinus and mild pulmonary hypertension. There was a history of maternal intake of sodium valproate during pregnancy.

Abstract
Women with epilepsy have a higher incidence of reproductive endocrine disorders than the general female population. These alterations include polycystic ovary syndrome, hyperandrogenemia, infertility, hypothalamic amenorrhea and hyperprolactinemia. Reproductive dysfunction is attributed both to epilepsy itself and to antiepileptic drugs (AEDs). Focal epileptic discharges from the temporal lobe may have a direct influence on the function of the hypothalamic-pituitary axis, thus altering the release of sex steroid hormones, including the production of luteinizing hormone, follicle-stimulating hormone, gonadotropin-releasing hormone and prolactin. AEDs may modulate hormone release from the hypothalamic-pituitary-gonadal axis and they may alter the metabolism of sex hormones and their binding proteins. Hepatic enzyme-inducing AEDs, such as carbamazepine and phenytoin, may be most clearly linked to altered metabolism of sex steroid hormones, but valproic acid, an enzyme inhibitor, has also been associated with a frequent occurrence of polycystic ovary syndrome and hyperandrogenism in women with epilepsy. Therefore, treatment of epilepsy and selection of AEDs are important for reproductive health in female patients. The aim of the present review is to critically evaluate the recently published data concerning the interactions between sex hormones, epilepsy and AEDs.

Abstract
PURPOSE To determine the influence of epilepsy and its treatment on pregnancy and its outcome. DESIGN Controlled, observational study. SETTING National Health Service maternity hospitals in Liverpool and Manchester regions. POPULATION 277 women with epilepsy (WWE) and 315 control women. METHODS WWE were recruited from antenatal clinics. Controls were matched for age and parity but not gestational age. Information was obtained by interview and from clinical records. MAIN OUTCOME MEASURES Obstetric complications, mode of delivery, condition of newborn. RESULTS Distribution of epilepsy syndromes was similar to previous surveys. Most WWE (67%) received monotherapy with carbamazepine, sodium valproate or lamotrigine. Half WWE had no seizures during pregnancy but 34% had tonic clonic seizures. Seizure-related injuries were infrequent. Pregnancies with obstetric complications were increased in women with treated epilepsy (WWTE 45%, controls 33%; p=0.01). Most had normal vaginal delivery (WWTE 63%, controls 61%; p=0.65). Low birth weight was not increased (WWTE 6.2%, controls 5.2%; p=0.69). There were more major congenital malformations (MCM) (WWTE 6.6%, controls 2.1%; p=0.02) and fetal/infant deaths (WWTE 2.2%, controls 0.3%; p=0.09). Amongst monotherapies MCM prevalence was highest with valproate (11.3%; p=0.005). Lamotrigine (5.4%; p=0.23) and carbamazepine (3.0%; p=0.65) were closer to controls (2.1%). There was no association between MCM and dose of folic acid pre-conception. CONCLUSION MCM were more prevalent in the babies of WWTE particularly amongst those receiving sodium valproate.

Abstract
OBJECTIVE To investigate the pregnancy outcome of patients with epilepsy. STUDY DESIGN A population-based study comparing all singleton pregnancies of patients with and without epilepsy was performed. Patients lacking prenatal care were excluded from the analysis. Deliveries occurred between the years 1988 and 2002 in a tertiary medical center. Stratified analysis, using a multiple logistic regression model, was performed to control for confounders. RESULTS During the study period 139 168 singleton deliveries occurred in our medical center. Of these, 220 (0.2%) were of patients with epilepsy. With the exception of gestational diabetes mellitus (GDM), no other significant differences regarding maternal outcomes were noted between the groups. However, a higher rate of congenital malformations was noted among the epileptic population (7.7% vs. 3.8%; p < 0.001). Also, a higher rate of cesarean deliveries (CD) was found among epileptic women (17.3% vs. 11.55%, p = 0.008). This association was persistent after controlling for possible confounders, using a multivariable analysis (OR = 1.5, 95% CI 1.1-2.3; p = 0.05). CONCLUSION The course of pregnancy of patients with epilepsy is favorable, except for higher rates of cesarean deliveries, GDM, and congenital malformations.

Abstract
OBJECTIVE The purpose of this Cochrane review was to determine the effectiveness of delivering preconception counseling interventions to women with epilepsy (WWE) as a means of reducing adverse pregnancy outcomes, increasing knowledge, and increasing intentions to plan pregnancy. METHODS Two hundred twenty-five citations were retrieved from a systematic search of the Cochrane Library and electronic databases: Medline (OVID), Scopus, CINAHL, PsychINFO, and ASSIA, and hand searches of relevant epilepsy and obstetric journals. RESULTS The search strategy identified 11 studies for consideration for inclusion. However, none met the required criteria for inclusion. CONCLUSIONS There is no robust evidence to inform the content, methods of delivery, or likely effectiveness of preconception counseling to improve pregnancy outcomes for WWE and their offspring. The value of counseling WWE prior to conception remains uncertain and requires evaluation in well-designed studies, appropriately powered to detect changes likely associated with both maternal and infant outcomes.

Abstract
As health care systems seek to provide patient-centered care as a cornerstone of quality, how to measure this aspect of quality has become a concern. Previous development of quality indicators for treating individual chronic disease has rarely included patient perspectives on quality of care. Using epilepsy as an exemplar, the authors sought to develop an approach to measuring patient-centered quality of care. They conducted six focus groups with adults with epilepsy. Using qualitative methods, the authors initially identified 10 patient-generated quality indicators, 5 of which were subsequently rated, along with literature-based quality indicators, by an expert panel using a modified RAND appropriateness methodology. The authors discuss similarities and differences in aspects of care patients and providers value as essential for good quality. The process presented in this article may serve as a model for incorporating patient perceptions of quality into the future development of quality indicators for chronic diseases.

Abstract
BACKGROUND The provision of preconception counselling to women with epilepsy (WWE) has become established as recommended practice and includes a review of drug treatment and the provision of information and advice on both seizure and treatment-related risks to both mother and child. In this review we assess the evidence regarding the effectiveness of preconception counselling for WWE. OBJECTIVES To determine the effectiveness of preconception counselling for WWE, measured by a reduction in adverse pregnancy outcome in both mother and child; increased knowledge of preconception issues in WWE and increasing intention to plan pregnancy. SEARCH STRATEGY We searched the Epilepsy Group's Specialized Register (30/01/2008), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 4), and electronic databases: MEDLINE (OVID) (1950-February 2008); SCOPUS (1966-March 2008); CINAHL (1982-March 2008); PsyclNFO (1806-March 2008); ASSIA (1987-March 2008). SELECTION CRITERIA Randomised control trials; including cluster and quasi-randomised trials, prospective cohorts, controlled before and after studies, and interrupted time series that compared the outcomes in mothers with epilepsy and infants of mothers with epilepsy who received preconception counselling, to the outcomes of mothers with epilepsy and their infants who received standard care or no intervention. DATA COLLECTION AND ANALYSIS The methodological quality of potentially relevant studies were assessed to determine appropriate inclusion. Where necessary, study authors were contacted for additional information. No studies met the review inclusion criteria. MAIN RESULTS The search strategy identified 11 studies for consideration of inclusion. However, none met the required criteria for inclusion. AUTHORS' CONCLUSIONS There is no evidence to inform the content, methods of delivery or effectiveness of preconception counselling to improve pregnancy outcomes for WWE and their offspring. The value of counselling delivered to WWE prior to conception, with the intention of reducing the risks of adverse outcome in mother and child, requires evaluation in well-designed studies, appropriately powered to detect changes in both maternal and infant outcome.

Abstract
BACKGROUND Although anxiety and depression in populations with epilepsy have been studied, no research on fear of childbirth in women with epilepsy have been conducted. The purposes of this study were to examine whether a significant difference occurred in fear of childbirth between pregnant women with epilepsy and pregnant healthy controls and to evaluate the most common fears. METHODS Fifty pregnant women with epilepsy and 50 pregnant women without epilepsy were assessed at a gestational age between 32 and 36 weeks of pregnancy, using two questionnaires for the measurement of fear of childbirth, an open question, and a clinical interview. RESULTS We found that during pregnancy, women with epilepsy experienced a significantly higher rate of fear of childbirth when compared with healthy controls, whereas after delivery, the experiences and feelings about childbirth are almost the same as those of women without epilepsy. CONCLUSIONS Our findings signify the importance of the assessment of the fear of childbirth, especially in women with epilepsy, and the need to offer professional and ad hoc support to those who suffer from it.

Abstract
The majority of epileptic disorders are not self-limiting over time, and therefore require a long-lasting and often even lifelong antiepileptic drug (AED) treatment, in Wi/omen with epilepsy, the influence of their disease on the possibility and course of pregnancies, as well as the potential impact of the AED treatment on mother and child, are crucial questions. This review addresses the clinically relevant knovledge concerning the impact of the disease itself and the AED treatment on fertility, pregnancy, delivery, the postpartum period, and teratogenicity. Some of the new AEDs appear to have a favorable profile due to a lack of clinically relevant interactions and promising teratogenic profiles. However, the finding of decreases in lamotrigine serum concentrations during hormonal contraception and pregnancy is an instructive example, shovt/ing that ongoing studies are urgently needed to further investigate stillunanswered questions. Several prospective multinational surveys are currently being performed, and should add essential information in this context.

Abstract
BACKGROUND The impact of chronic illness on families has long been noted in the literature, but in such studies families appear as ready-formed entities. This exploratory qualitative study addresses the largely unacknowledged work involved in the production of families and the maintenance of reproductive health by women with epilepsy, a condition whose symptoms and treatment have serious implications for all aspects of reproductive health. METHODS Qualitative in-depth interviews were conducted with a sample of 15 women aged 20-40 years diagnosed with epilepsy and recruited from across the UK. The women had a range of neurological symptoms and hence different diagnostic categories; most had been diagnosed during childhood or adolescence. Ten women had at least one child. RESULTS Women's experiences of healthcare services for key phases of reproduction are explored. While some women reported that they had received good healthcare, others reported that they were given inadequate information and that advice was offered too late to enable them to take appropriate action. DISCUSSION Management of both epilepsy and reproductive health involves work with a significant moral dimension, the accomplishment of which is contingent on appropriate and timely advice from healthcare practitioners.

Abstract
Women with epilepsy who were service users of Epilepsy Action in the United Kingdom (UK) completed a questionnaire on the risks of caring for their baby and whether they were provided with useful information on fulfilling their caring role (Epilepsy Action is the trading name of the British Epilepsy Association a major UK charity for those with epilepsy). The cohort of 84 all reported some problems. The following were rated as being the most problematic; caring for their baby outside the home and bathing, whereas breastfeeding was rated as much less problematic. Some problems were rated as severe, which meant some babies were put at undue risk. Approximately 50% had been provided with information about caring and managing risk. Eighty-six percent found this information useful. The main conclusion is that more extensive, well-planned research is needed on this topic. There is virtually nothing in the academic literature to guide practice and this is needed. Present guidelines tend only to cover what the women rate as less problematic, e.g. breastfeeding, whereas what they rate highly problematic is often not covered. This needs attention in updates.

Abstract
BACKGROUND Managing epilepsy during pregnancy is a critical challenge as maternal seizures may have deleterious effects on the fetus. While many patients with epilepsy have been managed successfully with antiepileptic drugs (AEDs), the potential teratogenicity of AEDs is a major concern. First-generation AEDs such as valproate have been associated with at least a 2-fold risk of fetal malformations compared with the general population. However, recent studies suggest that the newer AEDs given as monotherapy may have a lower teratogenic risk. The current case report adds to the growing experience of oxcarbazepine therapy in pregnant women with epilepsy. REVIEW SUMMARY This case report presents a 23-year-old female with a history of complex partial seizures (CPS) and mild depression. In high school, she had 2 initial tonic-clonic seizures and was placed on phenytoin monotherapy. She was subsequently placed on combination therapy (phenytoin + gabapentin) and was maintained on it for several years. Preceding a planned pregnancy, the patient was switched to oxcarbazepine and tapered off both phenytoin and gabapentin. The patient was maintained on oxcarbazepine monotherapy with a seizure-free pregnancy and delivered a normal, healthy baby girl. The patient breast-fed the infant for 6 months, supplemented with infant formula without any adverse effects. Subsequently, the patient has had a healthy second child while receiving oxcarbazepine during her pregnancy. CONCLUSION Although there are very limited data in the literature, this case illustrates that a patient with a history of CPS can be treated with oxcarbazepine with no adverse effects during and after pregnancy.

Abstract
Women with epilepsy should not be discouraged from becoming pregnant as the likelihood of having a healthy baby is very high. However, in such women, early and individualised counselling about pregnancy and contraception is essential. Ideally, pregnancies should be planned, folic acid (5 mg/day) given and antiepileptic drug (AED) treatment optimised well before conception to ensure that the lowest dosage that controls seizures is administered. When initiating AEDs in a woman of childbearing age, the most appropriate drug for the seizure type and syndrome should be chosen, although it is preferable to avoid valproate, because of a possible elevated risk of fetal malformations, when equi-effective agents are available for a given syndrome. In women who become pregnant while taking AEDs, fetal monitoring should include high-resolution ultrasonography before week 20 and measurement of serum alpha-fetoprotein levels. Amniocentesis is not routinely indicated. The measurement of blood concentrations of AEDs can be useful to ensure that the lowest possible maintenance dosage is being used, especially for those drugs whose pharmacokinetics are likely to change during pregnancy. Breastfeeding should be encouraged whatever the treatment administered.

Abstract
Pregnancies in women with epilepsy need careful management, by both the medical and obstetric teams, owing to the increased incidence of complications and adverse outcomes of pregnancy. By the time a pregnant woman with epilepsy presents, the major fetal organs are significantly formed, apart from the brain, and the development of which may be impaired by the maternal intake of valproate. Women of child-bearing age need to be counseled and told to seek advice regarding their anticonvulsant antiepileptic drug (AED) therapy, should they wish to become pregnant. All major AEDs are teratogenic, but the main risk to the developing fetus appears to be when the mother is on polytherapy, especially if sodium valproate forms part of the combination. Other issues that need to be discussed include the methods and consequences of prenatal screening, genetics of seizure disorder, folic acid and vitamin K supplements, labor, breast feeding and care and safety of the child.

Abstract
PURPOSE This study evaluated obstetric and neonatal outcome in a community-based cohort of women with active epilepsy (WWAE) compared with the general pregnant population receiving modern obstetric care. METHODS We reviewed the total population who gave birth between January 1989 and October 2000 at Kuopio University Hospital. Obstetric, demographic, and epilepsy data were collected prospectively from 179 singleton pregnancies of women with epilepsy and from 24,778 singleton pregnancies of unaffected controls. The obstetric data from the pregnancy register was supplemented with detailed neurologic data retrieved from the medical records. The data retrieved were comprehensive because of a follow-up strategy according to a predecided protocol. RESULTS During pregnancy, the seizure frequency was unchanged, or the change was for the better in the majority (83%) of the patients. We found no significant differences between WWAE and controls in the incidence of preeclampsia, preterm labor, or in the rates of caesarean sections, perinatal mortality, or low birth weight. However, the rate of small-for-gestational-age infants was significantly higher, and the head circumference was significantly smaller in WWAE. Apgar score at 1 min was lower in children of WWAE, and the need for care in the neonatal ward and neonatal intensive care were increased as compared with controls. The frequency of major malformations was 4.8% (-0.6-10.2%; 95% confidence interval) in the 127 children of WWAE. CONCLUSIONS Pregnancy course is uncomplicated and neonatal outcome is good in the majority of cases when a predecided protocol is used for the follow-up of WWAE in antenatal and neurologic care. Long-term follow-up of the neurologic and cognitive development of the children of WWAE is still needed.

Abstract
Optimal epilepsy management in teenage patients represents a particular challenge. These patients are often likely to respond more positively to a regimen that least disrupts their activities. In addition, as a patient group, they are more sensitive to peer perception. Current perceptions of older antiepilepsy drugs do not take into account frequent undesirable side effects or potential adverse interactions with other drugs. Furthermore, they often do not completely control seizures. Recent data suggest that not only do the newer antiepileptic drugs appear to be as efficacious as the older drugs, they also often have more favorable cognitive, cosmetic, and teratogenic side-effect profiles. In addition, newer antiepileptic drugs are being used more often in monotherapy. Successful management of epilepsy in teenagers requires that physicians not only understand the advantages that the newer antiepileptic drugs appear to provide but also consider the social impact of treatment on their patients.

Abstract
Valproic acid (sodium valproate) is widely used as a first-line antiepileptic agent. As with many antiepileptic drugs, there are a number of consequences associated with the use of valproic acid in women of child-bearing potential. Most pregnancies have a favourable outcome in women with epilepsy, and these women should not be discouraged from becoming pregnant. Unlike many other antiepileptic drugs, valproic acid has no significant pharmacokinetic interactions with the steroid hormones used in oral contraceptives. During pregnancy, the major risks to mother and child result from loss of seizure control on the one hand, and an elevated risk of major congenital malformations due to antiepileptic drug treatment on the other. In particular, an elevated risk of major congenital malformations associated with valproic acid use has been a consistent finding in studies of patient registries and several large case series. In addition, developmental delay, characterised by low verbal IQ, has also been reported in children exposed to valproic acid in utero, although the relative risk is not precisely known. For these reasons, pregnancies in women being treated with valproic acid need to be planned, and the benefit-risk ratios associated with continuing valproic acid or changing treatment need to be discussed with the patient. When treatment with valproic acid is the most appropriate treatment to achieve optimal seizure control, a number of measures can be implemented to minimise risk to the fetus. These include the use of the lowest possible effective dose of valproic acid in monotherapy (ideally <1000 mg/day), appropriate folic acid supplementation and close antenatal monitoring. Regular counselling is a prerequisite for informed planning of pregnancies and optimisation of the probability of a healthy outcome. Future research on valproic acid and pregnancy should involve risk assessment in large, population-based prospective studies.

Abstract
Being a woman with epilepsy is not the same as being a man with epilepsy. Epilepsy affects sexual development, menstrual cycle, aspects of contraception, fertility, and reproduction. MENSTRUAL CYCLE, EPILEPSY, AND FERTILITY: The diagnosis of epilepsy and the use of antiepileptic drugs (AEDs) present women of childbearing age with many problems; both the disease and its treatment can alter the menstrual cycle and fertility. CONTRACEPTION IN EPILEPSY: There are no contraindications to the use of nonhormonal methods of contraception in women with epilepsy (see Table 3). Nonenzyme-inducing AEDs (valproate sodium, benzodiazepines, ethosuximide, and levetiracetam) do not show any interactions with the combined oral contraceptive pill. There are interactions between the COCP and hepatic microsomal-inducing AEDs (phenytoin, barbiturates, carbamazepine, topiramate [doses above 200 mg/day], and oxcarbazepine) and also lamotrigine. SEXUALITY: The majority of women with epilepsy appear to have normal sex lives, although in some women with epilepsy, both the desire and arousal phases may be inhibited. PRECONCEPTION COUNSELING: Preconception counseling should be available to all women with epilepsy who are considering pregnancy. Women with epilepsy should be aware of a number of issues relating to future pregnancy, including methods and consequences of prenatal screening, genetics of their seizure disorder, teratogenicity of AEDs, folic acid and vitamin K supplements, labor, breast feeding, and childcare. PREGNANCY: The lowest effective dose of the most appropriate AED should be used, aiming for monotherapy where possible. Recent pregnancy databases have suggested that valproate is significantly more teratogenic than carbamazepine, and the combination of valproate sodium and lamotrigine is particularly teratogenic. Most pregnancies are uneventful in women with epilepsy, and most babies are delivered healthy with no increased risk of obstetric complications in women. BREAST FEEDING: All women with epilepsy should be encouraged to breastfeed their babies. The AED concentration profiled in breast milk follows the plasma concentration curve. The total amount of drug transferred to infants via breast milk is usually much smaller than the amount transferred via the placenta during pregnancy. However, as drug elimination mechanisms are not fully developed in early infancy, repeated administration of a drug such as lamotrigine via breast milk may lead to accumulation in the infant. THE CARE OF CHILDREN OF MOTHERS WITH EPILEPSY: Although there is much anxiety about the possible risks to a child from the mother's epilepsy, there is little published evidence. The risk of the child being harmed depends on the type of seizure and its severity and frequency, and this risk is probably small if time is taken to train mothers and caregivers in safety precautions. MENOPAUSE: During menopause, about 40% of women report worsening of their seizure disorder, 27% improve, and a third had no change. Hormone replacement therapy is significantly associated with an increase in seizure frequency during menopause, and this is more likely in women with a history of catamenial epilepsy. BONE HEALTH: Women with epilepsy are at increased risk of fractures, osteoporosis, and osteomalacia.

Abstract
There are many aspects to the management of epilepsy in women related to their role in reproduction. Some of these need to be considered in adolescents, some are related to pregnancy, concerning both the mother and her infant, and others with the menstrual cycle and the menopause. This review considers contraception, fertility, teratogenicity, and the use of folic acid. It also discusses the special investigations in pregnancy, hyperemesis, the effect of pregnancy on the control of epilepsy, the effect of seizures on the fetus, a first fit in pregnancy, pseudoseizures, seizures during delivery, vitamin K, breast feeding, postpartum maternal epilepsy, hereditary risks, counselling, catamenial epilepsy, the menopause, and bone density.

Abstract
A rational approach to the treatment of women of childbearing potential with epilepsy has been hampered by the lack of conclusive data on the comparative teratogenic potential of different antiepileptic drugs (AEDs). Although, several cohort studies on birth defects associated with AED use during pregnancy have been published, these have generally failed to demonstrate differences in malformation rates between AEDs, probably mainly due to insufficient power. In particular, pregnancies with new generation AEDs have been too few. In recent years, pregnancy registries have been introduced to overcome this problem--EURAP (an international collaboration), the North American, and the U.K. AED and pregnancy registries are observational studies that prospectively assess pregnancy outcome after AED exposure using slightly different methods. Each has enlisted 3-5,000 pregnancies in women with epilepsy, and the North American and the U.K. have released preliminary observations. Thus the U.K. registry reported a higher malformation rate with valproate, 5.9% (4.3-8.2%; 95% CI), than with carbamazepine, 2.3% (1.4-3.7%), and lamotrigine, 2.1% (1.0-4.0%). Most of the more recent cohort studies have also identified a nonsignificant trend toward a higher teratogenicity with valproate. These signals need to be interpreted with some caution since none of the studies to date have fully assessed the impact of possible confounders, such as type of epilepsy, family history of birth defects, etc. However, with increasing number of pregnancies it should be possible in the near future for the pregnancy registries to take such confounding factors into account and thus make more reliable assessments of the causal relationship between exposure to specific AEDs and teratogenic risks. While awaiting more conclusive results, it appears reasonable to be cautious in prescribing valproate to women considering to become pregnant if other suitable treatment alternatives, and with less teratogenic potential, are available. Any attempt to change treatment should, however, be accomplished well before conception. The importance of maintained seizure control must also be kept in mind, and the woman who needs valproate to control her seizures should not be discouraged from pregnancy, provided that counseling at the best of available knowledge is given.

Abstract
Bipolar disorder in women presents special diagnostic and treatment challenges to the clinician. The presentation of female bipolar may resemble depressive disorders, comorbid Axis I disorders, Axis II personality disorders, behavioral dysregulation, or general medical disorders; thus, it is critically important for clinicians to assess for a history of hypomania or mania when determining diagnosis in any woman presenting with psychological symptoms. Several gender differences may exist in the epidemiology and symptomatology of bipolar disorder, and each must be kept in mind during assessment. Rapid cycling and mixed states have been associated with female gender and may present diagnostic challenges as each often presents as major depression. Symptoms of postpartum psychosis tend to differ from the symptoms typically seen in bipolar mania; therefore, if postpartum psychosis is actually a manifestation of bipolar disorder, accurate diagnosis depends upon a knowledge of these differences. Special treatment considerations for bipolar disorder in women involve interactions between the illness and the female reproductive cycle. A risk of fetal malformation exists when some mood-stabilizing agents are used during conception and/or during the first trimester of pregnancy. Neurobehavioral teratogenicity and neonatal toxicity is also possible. Careful treatment management is necessary to reduce the risks to the fetus/infant and to effectively manage bipolar disorder in the mother. In treating women with bipolar disorder, clinicians should discuss the issue of pregnancy and associated risks of treatment versus no treatment with every patient of reproductive age. Further studies are needed on gestational timing and exposure to mood-stabilizing agents, especially newer agents recently approved or currently being considered for the treatment of bipolar disorder.

Abstract
This article concentrates on the practical management of those with seizures by general nurses. It focuses on the role of the hospital nurse in secondary care and the practice nurse in primary care. Both need to be conversant and practically competent to deal with the first-aid management of a seizure. They also need to know when medical assistance is required and how to act in an emergency. Epilepsy is a chronic long-term condition in adults and the main function of the nurse is advisory and educational. It is to act as a facilitator, and to assist adults to self-manage their epilepsy. Where the nurse is unable to provide this advice, appropriate referrals or contacts should be given.

Abstract
The potential teratogenicity of antiepileptic drugs (AEDs) is a major concern for women with epilepsy who are considering pregnancy. Traditional AEDs are associated with an at least twofold risk of fetal malformations compared with the general population. The risk of malformations with newer AEDs is unclear. This article reports the multicenter clinical experience in Argentina of pregnant women with epilepsy receiving AEDs. Of 114 pregnancies monitored, 16 newborns had anomalies: 3 cardiac, 3 skull, and 2 gastrointestinal malformations, and 8 facial dysmorphies. Most fetal anomalies were observed following exposure to phenobarbital, valproate, and carbamazepine. Of 55 babies exposed to the new-generation AED oxcarbazepine (20 as combination therapy and 35 as monotherapy), one malformation (cardiac) was reported (in a patient receiving oxcarbazepine and phenobarbital). Thus, newer AEDs may have a lower teratogenic risk than traditional AEDs. These data add to the growing experience with AED therapy in pregnant women with epilepsy.

Abstract
BACKGROUND The potential adverse effects of antiepileptic drug (AED) exposure in pregnancy have been well recognised but the relative risks of specific antiepileptic drug exposures remain poorly understood. OBJECTIVES To assess the adverse effects of commonly used antiepileptic drugs on maternal and fetal outcomes in pregnancy in women with epilepsy. Comparison of outcomes following specific antiepileptic drug exposures in utero to unexposed pregnancies in the general population or women with epilepsy are described. The current manuscript reports the first phase of this review which focuses upon neurodevelopmental outcomes in children exposed to antiepileptic drugs in utero. SEARCH STRATEGY We searched MEDLINE, Pharmline, EMBASE, Reprotox and TERIS from 1966 to December 2003. Review articles and conference abstracts were also hand searched. SELECTION CRITERIA All randomized controlled trials, prospective cohorts of children of pregnant women with and without epilepsy and case control studies (cases: developmental delay or impaired cognitive outcome, control: normal development) were included. DATA COLLECTION AND ANALYSIS Methodological quality was assessed using an adapted version of the Newcastle-Ottawa Scale. The wide variety of outcome measures and methodological approaches made meta-analysis difficult and a descriptive analysis of the results is presented. MAIN RESULTS PART A 1b - DEVELOPMENTAL OUTCOMES: The majority of studies were of limited quality. There was little evidence about which specific drugs carry more risk than others to the development of children exposed in utero. The results between studies are conflicting and while most failed to find a significant detrimental outcome with in utero exposure to monotherapy with carbamazepine, phenytoin or phenobarbitone, this should be interpreted cautiously. There were very few studies of exposure to sodium valproate. Polytherapy exposure in utero was more commonly associated with poorer outcomes, as was exposure to any AEDs when analysis did not take into account type of AED. The latter may reflect the large proportion of children included in these studies who were in fact exposed to polytherapy. REVIEWERS' CONCLUSIONS PART A 1b - DEVELOPMENTAL OUTCOMES: Based on the best current available evidence it would seem advisable for women to continue medication during pregnancy using monotherapy at the lowest dose required to achieve seizure control. Polytherapy would seem best avoided where possible. More population based studies adequately powered to examine the effects of in utero exposure to specific monotherapies which are used in everyday practice are required.

Abstract
The impact of some commonly prescribed anti-epilepsy drugs (AEDs) on female health is well documented. Yet many women continue to experience side effects such as menstrual irregularities, interactions with hormonal contraception/HRT and teratogenicity [Seizure 8 (1999) 201] through lack of awareness or opportunity to discuss problems with a health professional on a regular basis. The 'Ideal World' survey aimed to: (a) assess quality of current treatment information provision to women with epilepsy at different life stages (childbearing age, pre-conception/pregnancy, menopause); (b) identify information needs and wants with a view to ensuring that all women with epilepsy are counselled appropriately, in a timely manner and able to make informed choices about their treatment. The survey content was developed with a steering group of epilepsy specialists during 2001 (see 'ACKNOWLEDGEMENTS') and mailed to Epilepsy Action (formerly the British Epilepsy Association) UK female membership aged 19+ (approximately 12,000) during the period of January 2002. A sample of 2000 randomly selected responses was analysed by the Planning Shop International. The survey shows that women are not receiving important information about their condition and possible adverse effects of treatment, which could have profound implications for their health and the health of their unborn child. One third (33%) of women of childbearing age were not considering having children because of their epilepsy. Women with epilepsy need regular review and should receive appropriate information about the impact of their treatment in a timely manner.

Abstract
A group of 105 women (54 of whom were, and had only ever been, taking valproate for at least a year, and 51 who had only ever taken either lamotrigine or carbamazepine, for at least a year) were compared with a group of 50 women who did not have epilepsy: any oral contraceptive taken at the time of testing was recorded and blood levels of follicle stimulating hormone (FSH), luteinising hormone (LH), testosterone and prolactin were estimated from days 2 to 6 of the menstrual cycle (day 1 being the first day of bleeding) and an MRI scan made of their pelvis. Women with epilepsy in general were significantly more likely to exhibit evidence on MRI scanning, of polycystic ovaries (PCO): women taking valproate but not an oral contraceptive were significantly more likely to have clinical biochemical evidence of the polycystic ovarian syndrome (PCOS) with raised LH and/or testosterone levels between days 2 and 6 of their menstrual cycle than women who did not have epilepsy: this was not so for women taking lamotrigine or carbamazepine. Since the polycystic ovary syndrome has potentially serious consequences it is suggested that, where possible, valproate is avoided in women of child bearing potential.

Abstract
The prevalence of polycystic ovaries (PCO) and polycystic ovary syndrome (PCOS) in the general population is approximately 20 and 10%, respectively, and published studies suggest a similar prevalence in women with epilepsy. These data do not suggest that epilepsy is associated with a higher prevalence of the condition, and it would appear that the background prevalence of PCO and PCOS is the same as in the general population.
