Abstract
INTRODUCTION In women of childbearing age with epilepsy, 30% experience the comorbidity of polycystic ovary syndrome (PCOS), which is marked by a higher prevalence of hyperandrogenism. Our recent clinical observations indicate the potential contribution of hyperandrogenism-induced PCOS to epilepsy susceptibility, and this study aimed to unravel the underlying factors that increase the susceptibility of females to epilepsy. METHODS A letrozole-induced PCOS rat model was employed to simulate endogenous hyperandrogenism. The threshold of seizure was assessed through seizure kindling rates using pentetrazol and electroencephalogram recordings. Additionally, the role of androgens in epilepsy was verified through interventions using Diane-35. RESULTS This study revealed that letrozole-induced elevated testosterone levels and PCOS-related changes in female rats. PCOS rats, through pentetrazol-kindling, exhibited a reduced seizure threshold compared with controls. Elevated testosterone levels were observed in both the hippocampal and frontal brain tissues, accompanied by changes in circulation. Two weeks of Diane-35 intervention showed a tendency to alleviate these changes, modifying testosterone levels in both the plasma and brain tissue. Western blotting and immunohistochemistry revealed increased expression of GABA-A receptor in the hippocampus and decreased AMPA receptor expression in the frontal cortex, correlating with antiepileptic status in PCOS rats. CONCLUSION This study delves into the impact of elevated androgen levels on seizure threshold, providing crucial insights into the underpinnings of the comorbidity between PCOS and epilepsy. These findings significantly contribute to the evolving field of epilepsy research, emphasizing the imperative consideration of hormonal influences for the development of targeted therapeutic interventions in individuals with epilepsy and PCOS.

Abstract
Seizures, antiseizure medications, and the reproductive systems are reciprocally entwined. In Section 2 of this review, we outline how seizures may affect the hypothalamic-pituitary-gonadal axis, thereby altering sex steroids, and changes in sex steroids across the menstrual cycle and changes in pharmacokinetics during pregnancy may alter seizure susceptibility. The literature indicates that females with epilepsy experience increased rates of menstrual disturbances and reproductive endocrine disorders. The latter include polycystic ovary syndrome, especially for females on valproate. Studies of fertility have yielded mixed results. We aim to summarize and attempt to detangle the existing knowledge on these reciprocal interactions. The menstrual cycle causes changes in seizure intensity and frequency for many females. When this occurs perimenstrually, during ovulation, or in association with an inadequate luteal phase, it is termed catamenial epilepsy. There is a clear biophysiological rationale for how the key female reproductive neurosteroids interact with the brain to alter the seizure threshold, and Section 3 outlines this important relationship. Critically, what remains unknown is the specific pathophysiology of catamenial epilepsy that describes why not all females are affected. There is a need for mechanism-focused investigations in humans to uncover the complexity of the relationship between reproductive hormones, menstrual cycles, and the brain.

Abstract
PURPOSE OF REVIEW Epilepsy is a common neurologic condition amongst people with reproductive capacity, and assisted reproductive technology (ART) is being increasingly utilized. A recent population-based study described favorable outcomes of ART in this population, but other work shows how fluctuating sex hormones may influence medication concentrations and seizures. RECENT FINDINGS This review discusses hormonal influences on epilepsy and catamenial epilepsy, considerations regarding fertility in women with epilepsy, emerging ART outcomes, and management considerations for people with epilepsy undergoing ART. SUMMARY Utilizing ART is an effective treatment for people with epilepsy desiring pregnancy, but closer monitoring and antiseizure medication adjustments may be needed to ensure the best outcomes. More research is needed to better guide epilepsy care during ART.

[PMID: 37810040 PMCID: PMC10559853 DOI: 10.1016/j.heliyon.2023.e20098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 08/21/2023] [Accepted: 09/12/2023] [Indexed: 10/10/2023] Open
Abstract
Objective This study is aimed at comparing differential effect of Levetiracetam (LTC) monotherapy and Carbamazepine (CZP) monotherapy in W omen with epilepsy (WWE) on gonadal hormone. Methods 87 WWE were recruited comprising randomly of 46 and 41 on CZP and LTC group respectively with diagnosis and classification based on International League Against Epilepsy (ILAE). Reproductive hormones (Luteinizing Hormone (LH), Follicle stimulating hormone, progesterone, estradiol and testosterone) were assayed. National Hospital Seizure Severity Scale (NHSS) and Zung self-reporting depression scale (ZSRDS) were used to assess the seizure severity and the mood respectively. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 20. The Chi-square test was used to compare categorical variables while Student's t-test or its non-parametric equivalent where appropriate were used to compare continuous variables. Results Clinical characteristics were comparable in both groups except for ZSRDS (p = 0.048), NHSS (p = 0.012) and hip circumference (p = 0.037). The CZP group had a higher ASEX score and proportion of WWE with clinically significant sexual dysfunction (p < 0.001). WWE on LTC had similar hormonal profiles with those on CZP except for a higher median serum testosterone level (p = 0.004), and lower median serum LH (p = 0.006). Age was negatively associated with serum testosterone level for the 25th, 50th, and 75th quartile. However, the differential effect for AED type was only significant for the 25th quartile; with higher values in LTC. Conclusion The therapeutics implication of lower LH and testosterone levels in the LTC group compared to CZP group need to be explored.

Comparison of the probability of four anticonvulsant mood stabilizers to facilitate polycystic ovary syndrome in women with epilepsies or bipolar disorder-A systematic review and meta-analysis. Front Psychiatry 2023; 14:1128011. [PMID: 37229383 PMCID: PMC10203219 DOI: 10.3389/fpsyt.2023.1128011] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 04/17/2023] [Indexed: 05/27/2023] Open
Abstract
Background Patients treated with anticonvulsant mood stabilizers have a higher incidence of polycystic ovary syndrome (PCOS). However, there is no comparison between different anticonvulsant mood stabilizers. The purpose of this study was to systematically evaluate the prevalence of PCOS in women taking anticonvulsant mood stabilizers and compare the probability of PCOS caused by different anticonvulsant mood stabilizers. Methods Five databases, namely PubMed, Embase, Web of Science, Cochrane Library, and Clinical Trials, were searched for literature on anticonvulsant mood stabilizers and PCOS published up to October 28, 2022. This meta-analysis was performed using Revman 5.4, Stata 14.0, and R4.1.0, and effect size pooling was performed in fixed- or random-effects models based on the results of I2 and Q-test, and the surface under the cumulative ranking curve (SUCRA) was used for analysis to assess the cumulative probability of drug-induced PCOS. Publication bias was assessed by funnel plot Egger's test and meta regression. Results Twenty studies with a total of 1,524 patients were included in a single-arm analysis, which showed a combined effect size (95% CI) of 0.21 (0.15-0.28) for PCOS in patients taking anticonvulsant mood stabilizers. Nine controlled studies, including 500 patients taking medication and 457 healthy controls, were included in a meta-analysis, which showed OR = 3.23 and 95% CI = 2.19-4.76 for PCOS in women taking anticonvulsant mood stabilizers. Sixteen studies with a total of 1416 patients were included in a network meta-analysis involving four drugs, valproate (VPA), carbamazepine (CBZ), oxcarbazepine (OXC), and lamotrigine (LTG), and the results of the network meta-analysis showed that VPA (OR = 6.86, 95% CI = 2.92-24.07), CBZ (OR = 3.28, 95% CI = 0.99-12.64), OXC (OR = 4.30, 95% CI = 0.40-49.49), and LTG (OR = 1.99, 95% CI = 0.16-10.30), with cumulative probabilities ranked as VPA (90.1%), OXC (63.9%), CBZ (50.1%), and LTG (44.0%). Conclusion The incidence of PCOS was higher in female patients treated with anticonvulsant mood stabilizers than in the healthy population, with VPA having the highest likelihood of causing PCOS. The most recommended medication when considering PCOS factors is LTG. Systematic review registration identifier: CRD42022380927.

Abstract
To assess the risk factors for polycystic ovary syndrome (PCOS) in women with epilepsy (WWE) and develop a practical approach for PCOS screening based on clinical characteristic, blood indicator, and anti-seizure medication (ASM) profiles. This cross-sectional study was conducted with 248 WWE who were consecutively enrolled from the Epilepsy Center of West China Hospital between April 2021 and March 2022. The epilepsy characteristics, blood indicators, and use of ASMs were compared between WWE with and without PCOS. Multivariate logistic regression was used to identify the factors independently associated with PCOS. The differential analysis showed that younger age at onset of epilepsy (<13 years), a history of birth hypoxia, obesity (BMI ≥25 kg/m2 ), use of levetiracetam (LEV) (≥1 year), higher levels of cholesterol, luteinizing hormone (LH) and anti-Müllerian hormone (AMH), and lower levels of sex hormone-binding globulin were associated with PCOS (p < .05). Multivariate logistic regression identified that obesity (BMI ≥25 kg/m2 ), use of LEV (≥1 year), and higher levels of AMH and LH were independently associated with PCOS in WWE (p < .05). Obesity (BMI ≥25 kg/m2 ), LEV use (≥1 year), and elevated AMH and LH levels suggest an increased in the probability of occurrence of PCOS in WWE. The combination of these profiles provides a practical approach for screening PCOS in WWE.

Abstract
Patients with epilepsy develop reproductive endocrine comorbidities at a rate higher than that of the general population. Clinical studies have identified disrupted luteinizing hormone (LH) release patterns in patients of both sexes, suggesting potential epilepsy-associated changes in hypothalamic gonadotropin-releasing hormone (GnRH) neuron function. In previous work, we found that GnRH neuron firing is increased in diestrous females and males in the intrahippocampal kainic acid (IHKA) mouse model of temporal lobe epilepsy. Notably, GABAA receptor activation is depolarizing in adult GnRH neurons. Therefore, here we tested the hypothesis that increased GnRH neuron firing in IHKA mice is associated with increased GABAergic drive to GnRH neurons. When ionotropic glutamate receptors (iGluRs) were blocked to isolate GABAergic postsynaptic currents (PSCs), no differences in PSC frequency were seen between GnRH neurons from control and IHKA diestrous females. In the absence of iGluR blockade, however, GABA PSC frequency was increased in GnRH neurons from IHKA females with disrupted estrous cycles, but not saline-injected controls nor IHKA females without estrous cycle disruption. GABA PSC amplitude was also increased in IHKA females with disrupted estrous cycles. These findings suggest the presence of an iGluR-dependent increase in feed-forward GABAergic transmission to GnRH neurons specific to IHKA females with comorbid cycle disruption. In males, GABA PSC frequency and amplitude were unchanged but PSC duration was reduced. Together, these findings suggest that increased GABA transmission helps drive elevated firing in IHKA females on diestrus and indicate the presence of a sex-specific hypothalamic mechanism underlying reproductive endocrine dysfunction in IHKA mice.

Abstract
BACKGROUND Women with epilepsy (WWE) have potentially unique concerns regarding their sexual and reproductive health (SRH). Prior studies of WWE have focused narrowly on pregnancy and preconception experiences, and have not addressed concerns of nulliparous adolescent and young adult women not actively seeking pregnancy. METHODS We conducted individual semi-structured interviews with WWE 18-45 years of age. We sampled to maximize diversity of age and parity, and intentionally included many adolescent and young adult nulliparous women not actively planning pregnancy. Interviews broadly addressed participants' SRH concerns and experiences. Interviews were audio-recorded and transcribed. Two coders performed qualitative analysis using thematic analysis with deductive and inductive approaches. RESULTS Twenty WWE (median age 23 years, range 18-43 years) completed interviews. Twelve were nulliparous, six had children, one had a history of miscarriage only, and two were currently pregnant. WWE's narratives revealed significant concerns about family planning and reproductive health in the context of epilepsy, including: 1) seizures endangering pregnancies and children 2) teratogenic effects of antiseizure medication, 3) heritability of epilepsy, 4) antiseizure medication and epilepsy impacting fertility, and 5) interactions between antiseizure medication and contraception. CONCLUSION WWE, including nulliparous adolescent and young adult women who are not actively planning pregnancy, have significant concerns about how their epilepsy interacts with SRH. SRH counseling for WWE should begin during adolescence and be incorporated into the transition process from pediatric to adult healthcare. Insights from WWE may aid in the creation of relevant patient-facing educational resources as well as provider-facing training and tools to meaningfully support the reproductive decision-making of WWE throughout their childbearing years.

Abstract
AbstractGirls and women constitute nearly 50% of all epilepsy cases. Apart from the disease symptoms, epilepsy and antiseizure medications (ASMs) may also affect the reproductive function, pregnancy and even the health of their offspring. Therefore, it is very important to identify and summarize the problems and risks for women with epilepsy (WWE) of childbearing age, and offer internationally recognized methods through multidisciplinary collaboration. In this review, we summarize the reproduction-related problems with WWE and propose multidisciplinary management by epileptologists, gynecologists and obstetricians, as well as other experts, from preconception to delivery. Large, multicenter registries are needed to advance our knowledge on new ASMs and their effects on WWE and their offspring.

Abstract
OBJECTIVE The study is aimed at comparing effects of older drugs like carbamazepine (CBZ) and newer agent like levetiracetam (LEV) on polycystic ovarian syndrome (PCOS) in women with epilepsy (WWE). METHODS An interviewer-based questionnaire was used to obtain relevant clinical information from 50 WWE on CBZ and LEV monotherapy, respectively, and 50 age-matched controls. The diagnosis of epilepsy was clinical with electroencephalographic features taken into consideration and the seizures classified using the 2017 International League Against Epilepsy classification. The diagnosis of PCOS was based on the European Society for Human Reproduction and Embryology/American Society for Reproductive Medicine. RESULTS The frequency of PCOS and its subcomponent were higher among WWE compare to controls. PCOS was present in 22 (44%) of LEV group compare to 8 (16%) CBZ group. The frequency of its subcomponent was higher among those on LEV except for comparable effect with regard to oligomenorrhea. The levels of the sex steroid hormone were comparable in both groups of WWE except luteal phase luteinizing hormone, which was lower among the LEV group (P .001). The follicular phase estradiol level was lower (P .021), and follicle-stimulating hormone level was about 2-fold higher (P .03) among WWE compare to controls. The mean value testosterone was significantly lower among controls compared to WWE. CONCLUSIONS The increased frequency of PCOS and its subcomponent and the unsatisfactory effect of LEV compared to CBZ on reproductive endocrine function underscore the need for routine reproductive endocrine evaluation to improve overall quality of life.

Abstract
Epilepsy is a common chronic neurological disease that manifests as recurrent seizures. The incidence and prevalence of epilepsy in women are slightly lower than those in men. Polycystic ovary syndrome (PCOS), a reproductive endocrine system disease, is a complication that women with epilepsy are susceptible to, and its total prevalence is 8%-13% in the female population and sometimes as high as 26% in female epilepsy patients. The rate of PCOS increased markedly in female patients who chose valproate (VPA), to 1.95 times higher than that of other drugs. In addition, patients receiving other anti-seizure medications (ASMs), such as lamotrigine (LTG), oxcarbazepine (OXC), and carbamazepine (CBZ), also have reproductive endocrine abnormalities. Some scholars believe that the increase in incidence is related not only to epilepsy itself but also to ASMs. Epileptiform discharges can affect the activity of the pulse generator and then interfere with the reproductive endocrine system by breaking the balance of the hypothalamic-pituitary-ovarian (HPO) axis. ASMs may also cause PCOS-like disorders of the reproductive endocrine system through the HPO axis. Moreover, other factors such as hormone metabolism and related signalling pathways also play a role in it.

Abstract
The aim of the present study was to review existing knowledge on the impact of epilepsy in reproductive health of both sexes. Extensive searches of relevant documentation published until February 2020 were retrieved from PubMed and Google Scholar literature in English or in other languages with an English abstract. In females, epilepsy may lead to estrogen and androgen level abnormalities. Women with epilepsy may develop Polycystic Ovaries Syndrome (PCOS), anovulatory cycles, and menstrual disorders. In men, epilepsy may cause sex hormone dysregulation and influence spermatogenesis. Males with epilepsy may also suffer from sexual dysfunction. Antiepileptic drugs (AEDs) have adverse effects on peripheral endocrine glands, influence hormones' biosynthesis and protein binding, diminish the bioactivity of serum sex hormones, and lead to secondary endocrine disorders related to changes concerning body weight and insulin sensitivity. Valproic acid (VPA) was the first recognized AED to cause disturbances potentially due to metabolic changes and increasing weight. Women taking VPA may develop PCOS, while men may have sperm abnormalities and/or sexual dysfunction. Liver enzyme inducing AEDs may also cause menstrual and sexual disorders in women and sexual dysfunction in men. Newer AEDs are much safer but studies still suggest reduced sexuality and erectile dysfunction.

Abstract
Polycystic ovary syndrome (PCOS) has multiple etiologies including ovarian and adrenal hyperandrogenism, neuro-endocrine and hypothalamic-pituitary dysfunction, and disorders of peripheral insulin resistance. Obesity is neither necessary nor sufficient for the PCOS phenotype, and the association of PCOS with obesity is not universal, with national, cultural, and ethnic differences. Obesity, particularly visceral adiposity which is common in obese and non-obese women with PCOS, amplifies and worsens all metabolic and reproductive outcomes in PCOS. Obesity increases insulin resistance and compensatory hyperinsulinemia, which in turn increases adipogenesis and decreases lipolysis. Obesity sensitizes thecal cells to LH stimulation and amplifies functional ovarian hyperandrogenism by upregulating ovarian androgen production. Obesity increases inflammatory adipokines which, in turn, increase insulin resistance and adipogenesis. Lifestyle interventions focused on diet-weight loss and concurrent exercise are central to therapy which also commonly subsequently needs to include pharmacologic therapy. PCOS symptoms commonly improve with 5% to 10% weight loss, but 25% to 50% weight loss, usually achievable only through bariatric surgery, may be required for morbid obesity unresponsive to lifestyle-medical treatment. Bariatric surgery is a valuable approach to weight loss in PCOS where BMI is ≥40 kg/m2 when non-surgical treatment and/or induction of pregnancy have failed, and can be an initial treatment when BMI is ≥50 kg/m2. Further research in PCOS is needed to better understand the fundamental basis of the disorder, to ameliorate obesity, to correct hyperandrogenism, ovulation, hyperinsulinemia, and to optimize metabolic homeostasis.

Dynamic and Sex-Specific Changes in Gonadotropin-Releasing Hormone Neuron Activity and Excitability in a Mouse Model of Temporal Lobe Epilepsy. eNeuro 2018; 5:eN-NWR-0273-18.

Abstract
Reproductive endocrine disorders are prominent comorbidities of temporal lobe epilepsy (TLE) in both men and women. The neural mechanisms underlying these comorbidities remain unclear, but hypothalamic gonadotropin-releasing hormone (GnRH) neurons may be involved. Here, we report the first direct demonstrations of aberrant GnRH neuron function in an animal model of epilepsy. Recordings of GnRH neuron firing and excitability were made in acute mouse brain slices prepared two months after intrahippocampal injection of kainate (KA) or control saline, a well-established TLE model in which most females develop comorbid estrous cycle disruption. GnRH neurons from control females showed elevated firing and excitability on estrus compared with diestrus. By contrast, cells from KA-injected females that developed prolonged, disrupted estrous cycles (KA-long) showed the reverse pattern. Firing rates of cells from KA-injected females that maintained regular cycles (KA-regular) were not different from controls on diestrus, but were reduced on estrus. In KA-injected males, only GnRH neurons in the medial septum displayed elevated firing. In contrast to the diestrus versus estrus and sex-specific changes in firing, GnRH neuron intrinsic excitability was elevated in all KA-injected groups, indicating a role for afferent synaptic and neuromodulatory inputs in shaping overall changes in firing activity. Furthermore, KA-injected females showed cycle-stage-specific changes in circulating sex steroids on diestrus and estrus that also differed between KA-long and KA-regular groups. Together, these findings reveal that the effects of epilepsy on the neural control of reproduction are dynamic across the estrous cycle, distinct in association with comorbid estrous cycle disruption severity, and sex-specific.

Abstract
Women with epilepsy (WWE) face specific challenges throughout their lifespan due to the effects of seizures and antiepileptic drugs on hormonal function, potentially affecting both sexual and reproductive health. This review article addresses the most common issues of practical relevance to clinicians treating WWE: epidemiology and clinical presentations (including catamenial epilepsy), contraception, reproductive and sexual dysfunction, pregnancy, lactation, menopause-related issues (including bone health), and mental health aspects. Awareness of these gender-specific issues and implementation/adaptation of effective interventions for WWE results in significantly improved health-related quality of life in this patient population.

Abstract
OBJECTIVE Women with epilepsy (WWE) have lower birth rates than expected. The reasons for this are multifactorial and involve a complex interaction between reproductive endocrine and psychosocial factors. The effect of epilepsy surgery on reproduction in women with drug-resistant focal epilepsy has not previously been studied. METHODS Adult women of childbearing age (18-45years old) with drug-resistant focal epilepsy who had undergone a focal cortical resection between 1997 and 2008 at the Mayo Clinic in Rochester, MN were included in the study. Patients who had a history of hysterectomy or tubal ligation or who were menopausal at the time of surgery were excluded. Data on prior pregnancies and births, epilepsy history, surgical treatment, hormonal dysfunction, and socioeconomic status were obtained using a retrospective chart review. Associations between various clinical and demographic variables with changes in pregnancies and births from pre- to postsurgery were assessed using Chi-square or Fisher's exact test for categorical variables and Wilcoxon rank sum test for continuous variables. All tests were 2-sided, and p-values less than 0.05 were considered statistically significant. All analyses were performed using SAS software version 9.2 (SAS INC, Cary NC). RESULTS One hundred and thirteen women (average age: 30.5years) were included in the study. Average length of follow-up was 5.7years (SD-3.90). Sixty-four patients (57.5%) were nulliparous at the time of surgery. Sixty-one patients (54%) had never been married. Average number of pregnancies per patient prior to surgery was 0.93, and average number of births prior to surgery was 0.73. After surgery, a total of 17 women had a total of 35 pregnancies and 25 births. The average number of pregnancies and births after surgery was 1.27 and 0.96, respectively. Infertility was reported in one patient postoperatively. Patients who were younger at the time of surgery experienced a greater change in the number of pregnancies and births after surgery (p=0.0036 and 0.0060, respectively). Patients who received fewer antiepileptic drug medication trials by the time of surgery also had a greater change in the number of births after surgery (p=0.0362). Seizure onset localization and lateralization, presurgical seizure frequency, age at seizure onset, duration of epilepsy, and postoperative seizure outcome were not statistically significant factors. CONCLUSION The present retrospective observational study provides additional evidence for the importance of early surgical treatment in women with drug-resistant focal epilepsy. Patients who had received fewer medications prior to surgery were more likely to experience an increase in births following surgery. The significance of these findings requires further investigation but may support a role for earlier surgical intervention in the management of drug-resistant focal epilepsy.

Abstract
Infertility in individuals with neurologic disorders is complex in etiology and manifestation. Its management therefore often requires a multimodal approach. This review addresses the implications of spinal cord injury (SCI) and other neurologic disease on fertility, including the high prevalence of sexual dysfunction, ejaculation disorders and compromised semen parameters. Available treatment approaches discussed include assisted ejaculation techniques and assisted reproductive technology including surgical sperm retrieval and intracytoplasmic sperm injection (ICSI).

Abstract
BACKGROUND Levetiracetam (Lev) is a new antiepileptic drugs, proved to be effective and tolerance in regulatory trials, but these controlled trials do not always predict how useful a drug will be in day to day clinical practice, Retention rates can provide a better indication of efficacy and tolerability in everyday use. METHODS Totally 124 patients with more than 3 months disease course were enrolled in the study from June 2007 to December 2007. The LEV dose ranged from 10 to 60 mg/kg per day. Follow up visit were performed at 6 months, 12 months, 24 months and 36 months, and treatment effects, adverse effects were recorded. RESULTS The LEV retention rates at 6, 12, 24, and 36 months were 93.5% (116/124), 84.7% (105/124), 65.3% (81/124), and 58.9% (73/124), respectively. The predominant causes of withdrawal were lack of efficacy (62.7%) and serious adverse effects (17.6%). In addition, 48.6% (51/105), 60.5% (49/81) and 72.6% (53/73) patients were seizure-free for 12 months, 24 months and 36 months, respectively. In this study, 75 (60.5%) patients experienced at least one side effect. The most common side effects observed were irritability 38.7% (29/75), somnolence 17.3% (13/75), learning disability 16.0% (12/75), anorexia 17.3% (13/75), somnipathy 13.3% (10/75), and abnormal behavior 13.3% (10/75). CONCLUSIONS Our study revealed the high retention rate of LEV in Chinese children and adolescents with epilepsy.

Abstract
Evidence suggests that there may be drug interactions between antiepileptic drugs and hormonal therapies, which can present a challenge to endocrinologists dealing with patients who have both hypopituitarism and neurological diseases. Data are scarce for this subgroup of patients; however, data for the interaction of antiepileptic drugs with the pituitary axis have shown that chronic use of many antiepileptic drugs, such as carbamazepine, oxcarbazepine, and topiramate, enhances hepatic cytochrome P450 3A4 (CYP3A4) activity, and can decrease serum concentrations of sex hormones. Other antiepileptic drugs increase sex hormone-binding globulin, which reduces the bioactivity of testosterone and estradiol. Additionally, the combined oestrogen-progestagen contraceptive pill might decrease lamotrigine concentrations, which could worsen seizure control. Moreover, sex hormones and their metabolites can directly act on neuronal excitability, acting as neurosteroids. Because carbamazepine and oxcarbazepine can enhance the sensitivity of renal tubules, a reduction in desmopressin dose might be necessary in patients with central diabetes insipidus. Although the effects of antiepileptic drugs in central hypothyroidism have not yet been studied, substantial evidence indicates that several antiepileptic drugs can increase thyroid hormone metabolism. However, although it is reasonable to expect a need for a thyroxine dose increase with some antiepileptic drugs, the effect of excessive thyroxine in lowering seizure threshold should also be considered. There are no reports of significant interactions between antiepileptic drugs and the efficacy of human growth hormone therapy, and few data are available for the effects of second-generation antiepileptic drugs on hypopituitarism treatment.

Abstract
Complex, multidirectional interactions between hormones, seizures, and the medications used to control them can present a challenge for clinicians treating patients with epilepsy. Many hormones act as neurosteroids, modulating brain excitability via direct binding sites. Thus, changes in endogenous or exogenous hormone levels can affect the occurrence of seizures directly as well as indirectly through pharmacokinetic effects that alter the concentrations of antiepileptic drugs. The underlying structural and physiological brain abnormalities of epilepsy and the metabolic activity of antiepileptic drugs can adversely affect hypothalamic and gonadal functioning. Knowledge of these complex interactions has increased and can now be incorporated in meaningful treatment approaches for men and women with epilepsy.
