Abstract
Background Previous studies suggest a link between diet-derived circulating antioxidants and epilepsy, but the causal relationship is unclear. This study aims to investigate the causal effect of these antioxidants on epilepsy. Methods To assess the causal link between dietary antioxidants and epilepsy risk, we conducted a two-sample Mendelian randomization (MR) analysis. This involved examining antioxidants such as zinc, selenium, α- and γ-tocopherol, vitamin A (retinol), vitamin C (ascorbate), and vitamin E (α-tocopherol). We utilized instrumental variables (IVs) which were genetic variations highly associated with these commonly used antioxidants. Exposure data were sourced from a comprehensive genome-wide association study (GWAS). We aggregated data from the International League Against Epilepsy (ILAE) Consortium sample, which included various types of epilepsy, as an outcome variable. Finally, we applied the inverse variance weighting method and conducted sensitivity analyses for further validation. Results Based on the primary MR estimates and subsequent sensitivity analyses, the inverse variance weighting (IVW) method revealed that a genetically predicted increase in zinc per standard deviation was positively associated with three types of epilepsy. This includes all types of epilepsy (OR = 1.06, 95% CI: 1.02-1.11, p = 0.008), generalized epilepsy (OR = 1.13, 95% CI: 1.01-1.25, p = 0.030), and focal epilepsy (documented hippocampal sclerosis) (OR = 1.01, 95% CI: 1.00-1.02, p = 0.025). However, there is no evidence indicating that other antioxidants obtained from the diet affect the increase of epilepsy either positively or negatively. Conclusion Our research indicates that the risk of developing epilepsy may be directly linked to the genetic prediction of zinc, whereas no such association was found for other antioxidants.

Abstract
Imperata cylindrica is a globally distributed plant known for its antiepileptic attributes, but there is a scarcity of robust evidence for its efficacy. The study investigated neuroprotective attributes of Imperata cylindrica root extract on neuropathological features of epilepsy in a Drosophila melanogaster mutant model of epilepsy. It was conducted on 10-day-old (at the initiation of study) male post-eclosion bang-senseless paralytic Drosophila (parabss1) involved acute (1-3 h) and chronic (6-18 days) experiments; n = 50 flies per group (convulsions tests); n = 100 flies per group (learning/memory tests and histological examination). Administrations were done in 1 g standard fly food, per os. The mutant flies of study (parabss1) showed marked age-dependent progressive brain neurodegeneration and axonal degeneration, significant (P < 0.05) bang sensitivity and convulsions, and cognitive deficits due to up-regulation of the paralytic gene in our mutants. The neuropathological findings were significantly (P < 0.05) alleviated in dose and duration-dependent fashions to near normal/normal after acute and chronic treatment with extract similar to sodium valproate. Therefore, para is expressed in neurons of brain tissues in our mutant flies to bring about epilepsy phenotypes and behaviors of the current juvenile and old-adult mutant D. melanogaster models of epilepsy. The herb exerts neuroprotection by anticonvulsant and antiepileptogenic mechanisms in mutant D. melanogaster due to plant flavonoids, polyphenols, and chromones (1 and 2) which exert antioxidative and receptor or voltage-gated sodium ion channels' inhibitory properties, and thus causing reduced inflammation and apoptosis, increased tissue repair, and improved cell biology in the brain of mutant flies. The methanol root extract provides anticonvulsant and antiepileptogenic medicinal values which protect epileptic D. melanogaster. Therefore, the herb should be advanced for more experimental and clinical studies to confirm its efficacy in treating epilepsy.

Bosak M, Słowik A. Use of complementary and alternative medicine among adults with epilepsy in a university epilepsy clinic in Poland. Epilepsy Behav 2019; 98:40-44. [PMID: 31299531 DOI: 10.1016/j.yebeh.2019.06.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2019] [Revised: 06/02/2019] [Accepted: 06/02/2019] [Indexed: 12/28/2022]
Abstract
INTRODUCTION The use of complementary and alternative medicine (CAM) is becoming increasingly prevalent both in general population and patients with chronic diseases. The aim of the study was to determine the prevalence, reasons, and factors influencing the use of CAM in Polish patients with epilepsy (PWE). MATERIAL AND METHODS This prospective study involved PWE treated in a university epilepsy clinic. Data on epilepsy, antiepileptic drugs, level of education, vocational activity, and patterns of CAM were collected from a structured interview and from medical records. RESULTS The sample population consisted of 473 PWE (mean age: 35.3 years); 220 (46.5%) were females, and 228 (46.5%) were in remission. Overall 26.8% (127) of the cohort used at least one type of CAM. The CAM modalities most frequently used were herbal and dietary supplements (32.3%), energy healing (31.5%), and marijuana (27.6%). The internet was the most common source of information on CAM (45.7%). In one-third of subjects, CAM usage affected negatively compliance to standard treatment. Logistic regression analysis revealed several independent risk factors for CAM use in PWE: younger age, longer duration of epilepsy, lack of remission, and lower level of education. CONCLUSION A significant proportion of PWE uses CAM, and its usage may affect negatively compliance to standard treatment. Our findings highlight poor communication between patients and physicians with regard to CAM use. Healthcare professionalists should routinely check for CAM utilization in PWE to prevent potential harm related to its use.

Abstract
PURPOSE To identify the use pattern of complementary and alternative medicine (CAM) and its impact on antiepileptic drug (AED) adherence among patients with epilepsy. METHOD Potential studies were identified through a systematic search of Scopus, Science Direct, Google Scholar, and PubMed. The keywords used to identify relevant articles were "adherence," "AED," "epilepsy," "non-adherence," and "complementary and alternative medicine." An article was included in the review if the study met the following criteria: 1) conducted in epilepsy patients, 2) conducted in patients aged 18 years and above, 3) conducted in patients prescribed AEDs, and 4) patients' adherence to AEDs. RESULTS A total of 3,330 studies were identified and 30 were included in the final analysis. The review found that the AED non-adherence rate reported in the studies was between 25% and 66%. The percentage of CAM use was found to be between 7.5% and 73.3%. The most common reason for inadequate AED therapy and higher dependence on CAM was the patients' belief that epilepsy had a spiritual or psychological cause, rather than primarily being a disease of the brain. Other factors for AED non-adherence were forgetfulness, specific beliefs about medications, depression, uncontrolled recent seizures, and frequent medication dosage. CONCLUSION The review found a high prevalence of CAM use and non-adherence to AEDs among epilepsy patients. However, a limited number of studies have investigated the association between CAM usage and AED adherence. Future studies may wish to explore the influence of CAM use on AED medication adherence.

Abstract
Complementary and alternative medicine (CAM) includes a wide range of practices and products that are generally outside the use of conventional medicine as practiced in Western cultures. Use of CAM in persons with epilepsy is high, even compared to individuals with other chronic health conditions. In this study, we surveyed caregivers of children admitted to a regional epilepsy monitoring unit (EMU) in the southeast United States to assess CAM use among patients (N=225). Thirteen percent of respondents indicated current use of CAM by their child, 16% reported past use, and 43% reported interest in future use, most commonly in marijuana as a potential treatment (23%). Over 25% of respondents expressed interest in CAM use related to side effects of anti-epileptic medications. Regarding prayer as a form of CAM, a large majority of respondents in this sample identified as Christian and actively prayed for their child's illness, revealing a high prevalence of spiritual practices in this population. Eighty-one percent of respondents reported that they had not discussed CAM use with their doctor. Discussing CAM use with a health care provider was significantly related to past CAM use (p<.02), but not current use or willingness to try CAM in the future (p>.05). These results have important implications for future practice and support increased communication and patient education, as many anti-epileptic medications interact with certain herbs and supplements, posing a potential health risk and treatment barrier in this population.

Abstract
PURPOSE The current survey sought to identify the religious and cultural beliefs about the causes and treatment of epilepsy in people with epilepsy from Saudi Arabia and a number of other aspects relating to the possibility of cure, coping with the condition, and public awareness. METHODS Study instruments were developed on the basis of the literature, a focus group of people with epilepsy, and feedback from people in the field with local knowledge. These were then piloted. A survey was then carried out among a total of 110 adults with epilepsy. Participants were asked to complete questionnaires inquiring into their beliefs about the causes and range of treatments used for epilepsy. Each participant was allowed to choose more than one cause and more than one treatment method. The questionnaires were administered face to face by a clinical psychologist (HAA) to improve the quality of the responses. RESULTS We found that most adults with epilepsy in Saudi Arabia believe that epilepsy is a condition with multifactorial causation and for which more than one treatment method should be applied. A test from God was the most commonly ascribed cause (83% as well as 40% who believed that some cases of the illness were a punishment from God). The belief in the concept of God's will helped many in the cohort to accept their illness as part of their destiny. Ninety-six percent of the patients believed that there were also medical causes (such as an illness, brain insult, inflammation, heredity, contagion), and a similar proportion believed that there were also religious causes. Smaller proportions believed epilepsy could be due to cultural (78%) or psychosocial causes (64%). Thirty-four percent of people believed that there could be sometimes no cause, but only 2% thought that epilepsy never had any identifiable cause. Most patients did not believe that one treatment alone would help. Ninety-three percent of patients believed in medical treatment, 93% in religious treatment, and 64% in traditional treatments, and 7% believed in changing lifestyle (eating balanced food and positive thinking). Seventy-eight percent of the sample believed that their epilepsy was a curable illness. Ninety-six percent believed that faith and practicing religious rituals helped in coping with epilepsy, and 92% believed that family support helped in coping with epilepsy. Nine percent of patients had stopped their medication for religious reasons or because of a sense of shame, and 7% had at one time been forced by their family to stop their medication. Ninety-two percent of the sample reported having enough family support. Ninety-five percent believed that Saudi society needs more awareness to understand epilepsy. CONCLUSION In Saudi Arabia, religious and cultural beliefs about the causes and treatment of epilepsy exist alongside medical beliefs. The holding of religious beliefs, the practicing of religious rituals, and the presence of family support were found to be of great importance in coping with epilepsy, and their role needs to be fully appreciated in the medical management of the condition.

Abstract
Epilepsy is one of the most common neurological conditions worldwide, with many affected persons found in Asia, Latin America, and sub-Saharan Africa. Relatedly, the large majority found in these regions does not receive the appropriate therapy with antiepileptic drugs (AEDs), stemming from various reasons among which are lack of access to AEDs, social stigma, and negative cultural attitudes. The presence of epilepsy resistant to the available AEDs coupled with the frequent AED side effects has further fueled the widespread and growing use of botanicals as alternative therapy in several traditional societies in these developing countries since people with epilepsy (PWE) consider them as safe and effective. There have, however, been few botanicals that have been examined for their pharmacological activities related to traditional uses, and there is hardly any conclusive evidence regarding their efficacy in humans or knowledge about the exact mechanism(s) of action. This review discusses some botanical treatments that have been used for epilepsy in developing countries and the challenges faced. This article is part of a Special Issue entitled "Botanicals for Epilepsy".

Abstract
Epilepsy is known as one of the most frequent neurological diseases, characterized by an enduring predisposition to generate epileptic seizures. Oxidative stress is believed to directly participate in pathways leading to neurodegeneration, which serves as the most important propagating factor, leading to the epileptic condition and cognitive decline. Moreover, there is also a growing body of evidence showing the disturbance of antioxidant system balance and consequently increased production of reactive species in patients with epilepsy. A meta-analysis, conducted in the present review confirms an association between epilepsy and increased lipid peroxidation. Furthermore, it was also shown that some of the antiepileptic drugs could potentially be responsible for additionally increased lipid peroxidation. Therefore, it is reasonable to propose that during the epileptic process neuroprotective treatment with antioxidants could lead to less sever structural damages, reduced epileptogenesis and milder cognitive deterioration. To evaluate this hypothesis studies investigating the neuroprotective therapeutic potential of various antioxidants in cells, animal seizure models and patients with epilepsy have been reviewed. Numerous beneficial effects of antioxidants on oxidative stress markers and in some cases also neuroprotective effects were observed in animal seizure models. However, despite these encouraging results, till now only a few antioxidants have been further applied to patients with epilepsy as an add-on therapy. Based on the several positive findings in animal models, a strong need for more carefully planned, randomized, double-blind, cross-over, placebo-controlled clinical trials for the evaluation of antioxidants efficacy in patients with epilepsy is warranted.

Abstract
AbstractObjective:To describe the social, clinical and use-patterns characteristics of medicinal marijuana use among patients with epilepsy (PWEs).Methods:Eighteen PWEs with prescriptions for medicinal marijuana from a Canadian adult-epilepsy clinic were included in this study.Results:Eighteen patients had a prescription of medicinal marijuana from a total population of 800 PWEs in our center (2.2%). Mean age of patients was 30±7.4 (19-50) years. Twelve (67%) patients were males. Eleven (61%) patients had drug-resistant epilepsy. Eleven (61%) patients suffered a psychiatric comorbidity and reported the use of illicit substances or heavy alcohol or tobacco consumption. Only two (11%) patients were married; the rest of patients (89%) were single or divorced. The drug use pattern was similar among patients. All patients asked for marijuana permission in the epilepsy clinic. Most (83%) had a previous history of marijuana smoking, with a mean of 6.6±3 (1-15) years. The mean consumption dose was 2.05±1.8 (0.5-8) grams per day. Ten (56%) patients reported withdrawal seizure exacerbation when they stopped the marijuana. Only two patients (11%) reported side effects, and all patients found medicinal marijuana very helpful for seizure control and improvement of mood disorder.Conclusions:PWEs using medicinal marijuana have a common profile. They are usually young single men with drug-resistant epilepsy and psychiatric comorbidity. Most used marijuana before formal prescription and all believe the drug was effective on their seizure control. Because of the concurrent use of other antiseizure medications, it is complex to estimate the actual effect of marijuana.

Abstract
We examined self-reported complementary and alternative medicine (CAM) use among a largely indigent population with epilepsy. Overall CAM use was 70%, with the most frequently reported complementary and alternative medicines (CAMs) being medical marijuana (33%), prayer/spirituality (31%), meditation (19%), vitamins (19%), and stress management (16%). Forty-four percent of patients reported improved seizure control with CAMs. Stress management accounted for perceived seizure reduction in 74%, followed by marijuana (54%), prayer (49%), and yoga (42%). Among the most commonly used and helpful CAMs, stress management was not associated with specific demographic or clinical variables; marijuana use was significantly associated with lower age (users=35.2±10 years vs. nonusers=41.6±12; p<0.01) and lower income (under $15,000 40% use vs. 14% over $15,000; p<0.05); and prayer was significantly associated with female gender (male=21% vs. female=45%; p<0.01) and Black ethnicity (Black=55% vs. Hispanic=30% vs. White=23%; p<0.05). Taken together, our study was notable for the high rate of CAM utilization in a largely indigent population, with high rates of perceived efficacy among several CAM modalities.

Abstract
People with epilepsy (PWE) may use prescription and over-the-counter (OTC) drugs for the treatment of concomitant diseases. Combinations of these drugs, as well as dietary supplements, with antiepileptic drugs (AEDs) may lead to reduced control of seizures and of coexisting medical conditions and increased risk of adverse drug reactions (ADRs). The aims of this study were to obtain comprehensive lists of medications, dietary supplements, botanicals, and specific food components used by adult PWE and to evaluate the potential for interactions involving AEDs and patients' awareness of such potential interactions. We conducted a prospective, questionnaire-based study of PWE attending the Hadassah-Hebrew University Epilepsy Clinic over a period of 7months. The questionnaire interview included the listing of medications, medicinal herbs, dietary supplements, and specific food components consumed and the knowledge of potential drug-drug interactions (DDIs), and it was conducted by a pharmacist. Drug-drug interactions were analyzed via the Micromedex online database. Out of 179 patients who attended the clinic over the study period, we interviewed 73 PWE, of which 71 were included in our final analysis. The mean number of AEDs consumed per subject was 1.7 (SD: 0.8, range: 1-4). Forty (56%) subjects were also treated with other prescription and/or OTC medications, and thirty-four (48%) took dietary supplements. Drug families most prone to DDIs involving AEDs included antipsychotic agents, selective serotonin reuptake inhibitors, and statins. Two-thirds of study participants (67%) knew that DDIs may lead to ADRs, but only half (56%) were aware of the potential for reduced seizure control. Only 44% always reported treatment with AEDs to medical professionals. This study provides for the first time a comprehensive picture of prescription and OTC drugs and food supplements used by PWE. Despite a considerable potential for DDIs involving AEDs, patient awareness is limited, highlighting the importance of patient and caregiver education.

Doering JH, Reuner G, Kadish NE, Pietz J, Schubert-Bast S. Pattern and predictors of complementary and alternative medicine (CAM) use among pediatric patients with epilepsy. Epilepsy Behav 2013; 29:41-6. [PMID: 23933629 DOI: 10.1016/j.yebeh.2013.06.025] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2013] [Revised: 06/17/2013] [Accepted: 06/20/2013] [Indexed: 11/28/2022]
Abstract
Parents of pediatric patients with chronic conditions such as epilepsy increasingly opt for complementary and alternative medicine (CAM). However, data on the pattern and reasons of CAM use in childhood epilepsy are scarce. The objectives of this study were as follows: first, to characterize CAM use among pediatric patients with epilepsy by assessing its spectrum, prevalence, costs, and frequency of use; second, to evaluate the influence of CAM use on compliance and satisfaction with conventional care as well as to explore parent-child neurologist communication concerning CAM; and third, to investigate predictors of CAM use. A postal survey was administered to all parents of pediatric outpatients with epilepsy aged 6 to 12, who have received treatment at the neuropediatric outpatient clinic of the University Children's Hospital Heidelberg between 2007 and 2009. One hundred thirty-two of the 297 distributed questionnaires were suitable for inclusion in statistical analysis (44.7%). Forty-nine participants indicated that their children used CAM during the previous year (37.1%). Thirty different types of CAM were used, with homeopathy (55.1%), osteopathy (24.5%), and kinesiology (16.3%) being the most commonly named. A mean of 86€ (0€-500€) and 3h (1 h-30 h) per month was committed to CAM treatment. Only 53% of the users informed their child neurologist of the additional CAM treatment, while 85.6% of all parents wished to discuss CAM options with their child neurologist. Seventy-five percent of users considered the CAM treatment effective. Among the participants most likely to seek CAM treatment are parents whose children show a long duration of epileptic symptoms, parents who make use of CAM treatment themselves, and parents who value a holistic and natural treatment approach. A substantial portion of pediatric patients with epilepsy receive CAM treatment. The high prevalence of use and significant level of financial and time resources spent on CAM indicate the high importance of these treatment options for parents. On the other hand, communication concerning CAM with the child neurologist is largely insufficient despite the wish to speak about CAM. Complementary and alternative medicine users' high compliance with conventional treatment and high perceived effectiveness of CAM support an integrative approach to CAM for pediatric patients with epilepsy. Our study implies that in addition to open parent-child neurologist communication, active inquiry on CAM treatments is necessary to enable informed decision making by parents and to establish the suitability of CAM treatment for the patient. Reliable predictors for CAM use, which allow for improved identification of patients with a high likelihood to receive CAM treatment, are the duration of the illness, use of CAM by the parents themselves, and the desire of the parents to receive a holistic and natural treatment for their child.

Abstract
Background. Carbamazepine (CBZ) is a first-line antiepileptic drug which may be prone to drug interactions. Systematic review of herb- and food-drug interactions on CBZ is warranted to provide guidance for medical professionals when prescribing CBZ. Method. A systematic review was conducted on six English databases and four Chinese databases. Results. 196 out of 3179 articles fulfilled inclusion criteria, of which 74 articles were reviewed and 33 herbal products/dietary supplement/food interacting with CBZ were identified. No fatal or severe interactions were documented. The majority of the interactions were pharmacokinetic-based (80%). Traditional Chinese medicine accounted for most of the interactions (n = 17), followed by food (n = 10), dietary supplements (n = 3), and other herbs/botanicals (n = 3). Coadministration of 11 and 12 of the studied herbal products/dietary supplement/food significantly decreased or increased the plasma concentrations of CBZ. Regarding pharmacodynamic interaction, Xiao-yao-san, melatonin, and alcohol increased the side effects of CBZ while caffeine lowered the antiepileptic efficacy of CBZ. Conclusion. This review provides a comprehensive summary of the documented interactions between CBZ and herbal products/food/dietary supplements which assists healthcare professionals to identify potential herb-drug and food-drug interactions, thereby preventing potential adverse events and improving patients' therapeutic outcomes when prescribing CBZ.

Abstract
This systematic review aimed to estimate the prevalence of use of complementary and alternative medicine (CAM) in the UK. Five databases were searched for English language, peer-reviewed surveys published between 1 January 2000 and 7 October 2011. In addition, relevant book chapters and files from our own departmental records were searched by hand. Eighty-nine surveys were included, with a total of 97,222 participants. Most studies were of poor methodological quality. Across surveys on CAM in general, the average one-year prevalence of use of CAM was 41.1% and the average lifetime prevalence was 51.8%. In methodologically sound surveys, the equivalent rates were 26.3% and 44%, respectively. In surveys with response rates >70%, average one-year prevalence was nearly threefold lower than in surveys with response rates between 21% and 50%. Herbal medicine was the most popular CAM, followed by homeopathy, aromatherapy, massage and reflexology. Many patients and consumers in the UK use CAM; healthcare professionals should therefore responsibly advise their patients about the use of CAM.

Abstract
To understand the treatment-seeking behavior of people with epilepsy (PWE), 403 PWE were surveyed using structured face-to-face interviews. Nearly half (49.1%) of them had previously tried complementary and alternative medicine (CAM); traditional Chinese medicine (51.5%) and temple worship (48.0%) were the most frequently used forms of CAM. In the 155 patients with adult-onset epilepsy, seeking CAM was substantially more common among females (OR=2.11, 95% CI=1.05-4.24, P=0.036), patients with frequent seizures (OR=2.68, 95% CI=1.30-5.53, P=0.008), patients with less educated parents (OR=2.16, 95% CI=1.06-4.41, P=0.034), and patients with religious beliefs (OR=2.84, 95% CI=1.23-6.56, P=0.015). In the 248 patients with childhood-onset epilepsy, frequent seizures (OR=2.23, 95% CI=1.32-3.77, P=0.003) and lower level of parental education (OR=2.71, 95% CI=1.45-5.06, P=0.002) were significantly associated with CAM use. The patients who seek CAM before receiving conventional medical treatment decreased after implementation of the National Health Insurance (NHI) (34/188 before NHI vs 22/215 after NHI, P=0.023). This study showed that the prevalence of CAM use by PWE in Taiwan is high and that a convenient NHI program can affect treatment-seeking behavior.

Abstract
PURPOSE Use of concomitant medicines (CMs) is a common practice in people with epilepsy, as comorbidity in this group is frequent. Comedication, especially if it is self-administered, may pose significant hazards due to potential interactions. Some attention has been given to use of CMs in older patients with epilepsy but the CM habits of younger patients are much less known. The purpose of this study was to determine annual frequency of use, kind and cost of CMs in patients with epilepsy. MATERIAL AND METHODS The 12-month prospective multicentre study included 772 patients with a mean age of 27.4 yrs and a mean epilepsy duration of 12.5 yrs. Data on patient characteristics and treatment were collected during consecutive five visits. All CMs were classified according to the ATC system. RESULTS Of the 772 patients, 472 (61.1%) used at least one CM (3.4 drug/patient). OTC drugs constituted nearly 2/3 of all CMs. More women then men took CMs (p<0.002). The patients taking CMs were significantly older, had longer duration of epilepsy, more frequent comorbidities, and more seizures than patients not receiving any CM. Alimentary tract and metabolism drugs (28.9%), nervous system drugs (19.8%) and cardiovascular system drugs (11%) were the ones most commonly used. The annual cost of CMs was 76011.9 € PPP (mean cost/patient - 161.0 € PPP). CONCLUSIONS The results confirm that patients with epilepsy, regardless of age, take commonly CMs. Physicians should be more aware of this practice.

Abstract
OBJECTIVES This study was undertaken in order to determine the extent of the use of CAM in a UK headache clinic. DESIGN Ninety-two patients attending a headache clinic were given a questionnaire containing questions regarding their headaches and their use of CAM for headaches. SETTING Outpatient headache clinic, Birmingham, UK. Main outcome measures. The use of complementary and alternative therapies and predictive factors. RESULTS 32% of respondents had used a median of 3 different CAM therapies for their headache. The commonest source of recommendation of CAM use was a friend or relative (72%) and the commonest reason given for using CAM was as a last resort after trying all conventional therapies offered (48%). CAM therapies were perceived as beneficial by 60% of CAM users and no users perceived the CAM therapy to worsen their headache. 42% of CAM users had not disclosed it to their doctor or nurse, 80% of these giving the reason that the doctor or nurse never asked, rather than fear of discouragement or lack of understanding. Individuals who were in employment were more likely to have used CAM than those who were not. Binary logistic regression revealed Headache Impact Test (HIT-6) score to be a significant predictor of CAM use (Odds Ratio=1.38 [95% CI 1.05-1.81]). CONCLUSIONS As a matter of desperation, headache clinic patients try CAM therapies. Health care professionals involved in the management of headache should be aware of this. There is a need for evaluation of the benefits and safety of CAM therapies for headache.

Abstract
More efficacious and better tolerated treatments for epilepsy are clearly needed. Complementary and alternative medicine (CAM) has a long history of use in certain parts of the world and has gained increasing interest over the last decades in Western countries. In countries with a Western-based type of medical system, people with epilepsy (PWE) take natural products or engage in other forms of CAM mainly to enhance general health, but also to prevent seizures or to alleviate symptoms of comorbidities or side effects of antiepileptic medications. In other countries, well developed medical systems, such as traditional Chinese Medicine and Ayurveda, are often the basis for treating PWE. Based on anecdotal reports of efficacy in PWE, natural products from these and other traditions are increasingly being studied in animal models of epilepsy, and candidates for further clinical development have been identified. It is likely, therefore, that natural products will be further evaluated for safety, tolerability and efficacy in PWE with drug-resistant seizures.

Abstract
OBJECTIVE To determine the prevalence of herb and dietary supplement use and to provide a comprehensive analysis of factors influencing the use of these products in patients with epilepsy. METHODS We performed a cross-sectional study using self-administered questionnaires in a selected group of patients who were receiving care at a tertiary epilepsy center. Logistic regression was used to measure the association between the demographic variables and herb and dietary supplement use. In addition, we performed a MEDLINE search for each of the herb and dietary products used by our patients to determine the effect of these products on seizures and on their potential for interactions with other drugs metabolized by the liver. RESULTS One hundred eighty-seven patients completed the survey. Fifty-six percent of this group of patients with epilepsy used herbs and dietary supplements at the time of the survey. A considerable portion (71%) of these patients reported the use of these products to their physician, and most of them relied on their physicians as the primary source of information. Most of the patients used dietary supplement for health promotion rather than to specifically benefit their epilepsy condition. Approximately one-third of patients used herb or dietary supplements that had the potential to increase seizures (16%) or to interact with hepatically metabolized drugs (19%). The most powerful independent predictors of herb and dietary supplement use were partial epilepsy [odds ratio (OR) 3.36; 95% confidence interval (CI) 1.27-8.88] and Caucasian race (OR 3.55; 95% CI 1.11-11.34). CONCLUSION Patients with epilepsy commonly used dietary supplements along with their antiepileptic medications. The majority of these patients used herb and dietary supplements for health promotion rather than because of dissatisfaction with conventional treatment. It is important that physicians involved in the care of patients with epilepsy routinely inquire about the use of dietary supplements and that they make use of reliable resources to assess the safety of these products with regard to modification of seizure risk and the potential for interactions with antiepileptic drugs.

Abstract
Botanicals and herbs have a centuries-old tradition of use by persons with epilepsy, in many cultures around the world. At present, herbal therapies are tried by patients in developing as well as developed countries for control of seizures or adverse effects from antiepileptic drugs (AEDs), or for general health maintenance, usually without the knowledge of physicians who prescribe their AEDs. Well-designed clinical trials of herbal therapies in patients with epilepsy are scarce, and methodological issues prevent any conclusions of their efficacy or safety in this population. Furthermore, some botanicals and herbs may be proconvulsant or may alter AED metabolism. In spite of these limitations, further preclinical evaluation of botanicals and herbs and their constituent compounds using validated scientific methods is warranted based on numerous anecdotal observations of clinical benefit in patients with epilepsy and published reports showing mechanisms of action relevant to epilepsy or anticonvulsant effects in animal models of epilepsy. This review highlights the use of herbal therapies for epilepsy, outlines the role of the U.S. Food and Drug Administration in regulating herbal products, and presents the author's approach to the scientific assessment of herbal therapies as potential therapies for patients with epilepsy.

Abstract
PURPOSE OF REVIEW Complementary and alternative medical therapies include herbs, acupuncture, and mind-body therapies. This review highlights the findings of recently published studies of complementary and alternative medical therapies and epilepsy, and provides an update of the US Food and Drug Administration's role in regulating herbal products. RECENT FINDINGS Complementary and alternative medical therapies are often tried by patients with epilepsy, frequently without physician knowledge. Many modalities have been evaluated in patients with epilepsy, though methodological issues preclude any firm conclusions of efficacy or safety. Some herbal medicines have been shown experimentally to have mechanisms of action relevant to epilepsy and promising actions in animal models. SUMMARY There is currently a paucity of credible evidence to support the use of complementary and alternative medical therapies in patients with epilepsy. Herbal medicines traditionally used for epilepsy and compounds isolated from them, as well as other herbal medicines and their constituent compounds that have been shown experimentally to have mechanisms of action relevant to epilepsy, should undergo further preclinical evaluation with a view towards clinical development under the new US Food and Drug Administration guidelines. Additional studies of other, nonherbal complementary and alternative medical therapies are also warranted based on anecdotal observations or pilot studies that suggest a favorable risk-benefit ratio.

Abstract
Background Studies have shown that a significant proportion of people with epilepsy use complementary and alternative medicine (CAM). CAM use is known to vary between different ethnic groups and cultural contexts; however, little attention has been devoted to inter-ethnic differences within the UK population. We studied the use of biomedicine, complementary and alternative medicine, and ethnomedicine in a sample of people with epilepsy of South Asian origin living in the north of England. Methods Interviews were conducted with 30 people of South Asian origin and 16 carers drawn from a sampling frame of patients over 18 years old with epilepsy, compiled from epilepsy registers and hospital databases. All interviews were tape-recorded, translated if required and transcribed. A framework approach was adopted to analyse the data. Results All those interviewed were taking conventional anti-epileptic drugs. Most had also sought help from traditional South Asian practitioners, but only two people had tried conventional CAM. Decisions to consult a traditional healer were taken by families rather than by individuals with epilepsy. Those who made the decision to consult a traditional healer were usually older family members and their motivations and perceptions of safety and efficacy often differed from those of the recipients of the treatment. No-one had discussed the use of traditional therapies with their doctor. The patterns observed in the UK mirrored those reported among people with epilepsy in India and Pakistan. Conclusion The health care-seeking behaviour of study participants, although mainly confined within the ethnomedicine sector, shared much in common with that of people who use global CAM. The appeal of traditional therapies lay in their religious and moral legitimacy within the South Asian community, especially to the older generation who were disproportionately influential in the determination of treatment choices. As a second generation made up of people of Pakistani origin born in the UK reach the age when they are the influential decision makers in their families, resort to traditional therapies may decline. People had long experience of navigating plural systems of health care and avoided potential conflict by maintaining strict separation between different sectors. Health care practitioners need to approach these issues with sensitivity and to regard traditional healers as potential allies, rather than competitors or quacks.

Abstract
Complementary and alternative medicine (CAM) is recognized to be commonly used by patients, yet there have been few studies regarding the scope of CAM use by patients with epilepsy. This study assessed usage and perceptions of CAM by patients with epilepsy in the midwest of the United States. A 25-item survey was administered to adult patients with epilepsy, and data were collected from 228 patients. The survey collected demographics, specific CAM usage, adverse effects of CAM therapy, and perceptions of the effectiveness of CAM. Thirty-nine percent reported using CAM; 25% reported using CAM specifically for their epilepsy. Prayer/spirituality was the most commonly used form of CAM (46%), followed by "mega" vitamins (25%), chiropractic care (24%), and stress management (16%). CAM use is common among midwestern patients with epilepsy, although the pattern of use may be slightly different than in other regions of the United States and elsewhere.

Kim IJ, Kang JK, Lee SA. Factors contributing to the use of complementary and alternative medicine by people with epilepsy. Epilepsy Behav 2006; 8:620-4. [PMID: 16530015 DOI: 10.1016/j.yebeh.2006.01.020] [Citation(s) in RCA: 25] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2005] [Revised: 01/18/2006] [Accepted: 01/26/2006] [Indexed: 11/20/2022]
Abstract
We evaluated the factors that influence the use of complementary and alternative medicine (CAM) by people with epilepsy. Two hundred forty-six people were recruited from an outpatient clinic. Data on CAM utilization in the past 5 years as well as in the near future were collected via face-to-face structured interviews, and the factors contributing to CAM use were determined by multivariate analysis. About one-third of the participants (31.3%) reported using CAM in the past 5 years, and an equal number (30.5%) were willing to use CAM in the future. CAM use in the past was independently related to gender, economic status, and a belief in the safety of CAM use, whereas CAM use in the near future was independently associated with experience with CAM use in the past and a belief in the safety of CAM use.
