Abstract
In recent years, there has been growing interest in the influences of food-drug interactions on the metabolism of antiseizure medications (ASM) and the management of epilepsy. Studies have proven the effectiveness of the ketogenic diet (KD) in controlling refractory epilepsy. However, dietary interventions such as the KD or its variants may induce significant changes in serum drug concentrations which counteracts the anticonvulsive effects of ASMs, leading to an increased risk of developing seizures. Interactions with enzymes within the cytochrome P450 system may also explain the dietary influences on serum concentrations of antiseizure drugs. The bioavailability of ASMs is also affected by several foods and nutritional supplements. Nevertheless, more studies are warranted to explore the mechanisms underlying food-drug interactions and the risks and benefits of combined drug-diet therapy.

Abstract
INTRODUCTION Antiseizure medications (ASMs) are the primary treatment option for epilepsies of wide etiologies, however, about 10-20% of children do not gain sustained seizure control and in this case, it is worth investigating "alternative" therapeutic approaches aside from ASMs. Nowadays, non-pharmacological strategies for epilepsy treatment encompass dietary interventions, neurostimulation-based techniques, and biobehavioral approaches. AREAS COVERED A search on PubMed database was conducted. Experimental and clinical studies, as well as meta-analysis and structured reviews on the latest non-pharmacological treatments for drug-resistant epilepsy (DRE) in children, were included. Special attention is given to the efficacy and tolerability outcomes, trying to infer the role novel approaches may have in the future. EXPERT OPINION The large heterogeneity of primary clinical outcomes and the unavoidable subjective response of each patient to treatments prevents Researchers from the identification of a single, reliable, approach to treat DRE. The understanding of fine pathophysiologic processes is giving the way to the use of alternative therapies, such as the well-known ketogenic diet, in a "personalized" view of treatment. The goal is to apply the non-pharmacological treatment most suitable for the patient's sake.

Abstract
OBJECTIVE EGb 761, a plant extract obtained from the leaves of the Ginkgo biloba tree, is widely used in modern medicine and traditional medicine applications in the treatment of many diseases. However, in some clinical case reports, it has been suggested that G. biloba causes epileptic seizures. A limited number of experimental animal studies related to the effects of G. biloba on epileptic seizures do not provide sufficient information on the solution of a serious clinical problem with contrasting findings. We aimed to investigate the effects of EGb 761 administered in different doses to adult male Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats which is the genetic animal model of absence epilepsy, on absence seizures using in vivo electrophysiological method. In addition, the effects of EGb 761 doses on locomotor behavior of WAG/Rij rats were evaluated with open-field and rotarod behavioral tests. METHODS 50, 100, 200, and 400 mg/kg doses of EGb 761 were administered to male WAG/Rij rats with implanted EEG electrodes by oral gavage for 28 days. Evaluation of absence seizures was performed on spike-wave discharges (SWDs) in EEG recorded for 4 h each week. The number of SWDs, the total duration of SWDs, and the mean duration of SWD were determined for the analysis. RESULTS In the group treated with 400 mg/kg EGb 761, the number of SWDs and the mean duration of SWD at the 1st and 7th doses and the total duration of SWDs at the 1st, 7th and 14th doses were significantly increased (p < 0.05). In all experimental groups treated with EGb 761 doses, there was no significant change in locomotor activity in the open-field and the rotarod tests. CONCLUSION Ginkgo biloba extract EGb 761 increased the epileptic SWD parameters of WAG/Rij rats at high doses (400 mg/kg), causing a pro-epileptic effect on absence seizures. It should be noted that in patients with epilepsy and in high-dose applications, G. biloba extract EGb 761 may lead to an increase in neuronal excitability.

Evaluation of Anticonvulsant Activity of 80% Methanolic Root Bark Extract and Solvent Fractions of Pentas schimperiana (A. Rich.) Vatke (Rubiaceae) in Swiss Albino Mice. Adv Pharmacol Pharm Sci 2021; 2021:6689879. [PMID: 34212153 PMCID: PMC8205597 DOI: 10.1155/2021/6689879] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 03/27/2021] [Accepted: 05/06/2021] [Indexed: 01/03/2023] Open
Abstract
Background Epilepsy is one of the most common serious neurological disorders, responsible for substantial morbidity and mortality due to limited efficacy and negative properties of antiepileptic drugs. Medicinal plants are believed to be an important source of new chemical substances with potential therapeutic effects. Pentas schimperiana (A. Rich.) Vatke is a medicinal plant used in Ethiopian traditional medicine for the treatment of epilepsy. However, it lacks scientific investigation on its anticonvulsant activity. Therefore, this study was conducted to evaluate the anticonvulsant activity of 80% methanol root bark extract and solvent fractions of Pentas schimperiana (A. Rich.) Vatke in mice. Methods Anticonvulsant activity was evaluated by using the pentylenetetrazole and maximal electroshock-induced seizure test. The 80% methanolic root bark extract was subjected to successive fractionation with solvents differing polarity, i.e., chloroform, butanol, and water. The test groups received 100, 200, and 400 mg/kg bodyweight of extract and its solvent fractions. Result The ME400 and BF400 at the higher dose exhibited a significant (p < 0.001) anticonvulsant effect in both the pentylenetetrazole and maximal electroshock-induced seizure test compared with control. However, chloroform fraction only showed a significant (p < 0.001) anticonvulsant effect in the PTZ-induced seizure test, while aqueous fraction had least anticonvulsant activity in both seizure-induced tests. Phytochemical screening of Pentas schimperiana (A. Rich.) Vatke root bark extract revealed the presence of alkaloids, saponins, flavonoids, phenols, steroids, terpenoids, and tannins. Conclusion This study indicated that the plant has anticonvulsant activity and is considered as a potential source to develop a new antiepileptic drug.

Pharmacodynamic and pharmacokinetic interactions of hydroalcoholic leaf extract of Centella asiatica with valproate and phenytoin in experimental models of epilepsy in rats. JOURNAL OF ETHNOPHARMACOLOGY 2021; 270:113784. [PMID: 33429032 DOI: 10.1016/j.jep.2021.113784] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 10/21/2020] [Accepted: 01/04/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Centella asiatica (CA) is commonly used herbal medicine for treatment of epilepsy. CA has CYP2C9, CYP2D6 and CYP3A4 enzymes inhibition property and used as an adjuvant therapy with conventional antiepileptic drugs (AEDs). That may be responsible for herb-drug interaction. AIM OF THE STUDY The present study was planned to evaluate interactions profile of hydroalcoholic extract Centella asiatica (HECA) with antiepileptic drugs in experimental models of epilepsy in rats. MATERIALS AND METHODS Wistar rats (175-200 g) were used. In the pharmacodynamic interaction study, seizures were induced using pentylenetetrazole (PTZ) (60 mg/kg, i.p.) and maximal electroshock seizure (MES) (70 mA for 0.2 s). The therapeutic and sub-therapeutic doses of valproate (VPA) and phenytoin (PHT) were co-administrated with HECA in PTZ and MES model of seizures respectively. Behavioural parameters were assessed using elevated plus maze test and passive avoidance paradigm. Rat brain oxidative stress parameters were also assessed. In the pharmacokinetic interaction study, the serum levels of the VPA and PHT were estimated at different time intervals by HPLC and pharmacokinetic parameters were analyzed by WinNonlin software. RESULTS The VPA and PHT produced complete protection against seizures in their therapeutic doses but not with sub-therapeutic doses. However, co-administration of HECA with a sub-therapeutic dose of VPA and PHT enhanced the protection of seizures and significantly (p < 0.001) attenuated the seizure induced oxidative stress and cognitive impairment. It also significantly increased (p < 0.001) serum levels of VPA and PHT. The alterations in pharmacokinetic parameters (maximum serum concentration, area under the curve, clearance) of AEDs were also found with co-administration of HECA. CONCLUSION The results suggested that co-administration of HECA could improve the therapeutic efficacy of VPA and PHT. But, alteration in pharmacokinetic parameters revel that needs critical medical supervision to avoid any toxic reactions.

Abstract
When managing epilepsy, there is a temptation to focus care with respect to the last and the next seizure. However, epilepsy is a multifaceted chronic condition and should be treated as such. Epilepsy comes with many physical risks, psychological effects, and socioeconomic ramifications, demanding a long-term commitment from the treating physician. Patients with epilepsy, compared to other chronically ill patient populations, have a worse quality of life, family function, and less social support. The majority of patients are well controlled on antiseizure drugs. However, approximately one-third will continue to have seizures despite optimized medical management. The primary aim of this article is to explore the long-term management of chronic epilepsy, and to address some of the particular needs of patients with chronic epilepsy.

Abstract
Background: Lycium chinense fruit (LCF) is widely distributed in East Asia that has been used traditionally for antiaging purposes. This study was performed to examine the effects of LCF on attention and cognitive function in healthy young people. Materials and Methods: An 11-week, double-blind, randomized, placebo-controlled, crossover trial of 74 patients was conducted and its data were collected on Kyung-Hee University Korean Medical Hospital, Seoul, Korea. In crossover treatment, LCF or placebo was administered three times a day, total 3600 mg as two capsules of 600 mg once for 4 weeks with 3-week washout each. The computerized neurocognitive function test (CNT), the Korean version of the attention-deficit/hyperactivity disorder rating scale-IV, the clinical global impression rating scale, and the Frankfurt attention inventory (FAIR) for two groups were conducted 0 week before and 4 week, 11 week after the experiment, and significant mean changes of these tests for within group or two groups were measured by paired t-test or unpaired t-test. Results: The administration of LCF or placebo crossover for 8 weeks in healthy young people presented significant improvement in the verbal learning test, digit span forward test, digit span backward test, auditory continuous performance task of CNT, and FAIR-performance value compared with the placebo group (each group n = 43, P < 0.05). Conclusion: Thus, the consumption of LCF might be beneficial to increase learning and memory through attention and cognitive enhancing effect in normal young people, at an average age of 18 years of age.

Abstract
PURPOSE OF REVIEW This article reviews the management of patients with medically responsive epilepsy, including discussion of factors that may lead to transient breakthrough seizures and patient and physician strategies to maintain freedom from seizures. RECENT FINDINGS Imperfect adherence, unanticipated changes in ongoing medical therapy, inadvertent use of proconvulsants or concurrent medications that alter epilepsy medication kinetics, and a variety of seizure precipitants such as stress or sleep deprivation may alter long-term seizure control. SUMMARY The majority of patients with epilepsy are medically responsive. Many potential factors may lead to breakthrough seizures in these patients. Identification of these factors, patient education, and use of self-management techniques including mindfulness therapy and cognitive-behavioral therapy may play a role in protecting patients with epilepsy against breakthrough seizures.

Abstract
Kratom is an herbal compound that has been used as a recreational drug though is not regulated by the Food and Drug Administration. We report a 19-year-old male with recurrent seizures that developed during daily Kratom abuse as a self-treatment for anxiety. Following recurrent focal impaired awareness seizures in addition to generalized tonic-clonic seizures, he was begun on anti-seizure drugs. Seizures subsided after completing rehabilitation. Brain MRI at 29 months revealed bilaterally symmetric T1-hyperintensity in globus pallidus, subthalamic nuclei, and cerebral peduncles. Our case suggests Kratom abuse may be associated with structural brain lesions on MRI and symptomatic focal epilepsy.

Abstract
Context In 2001 the Institute of Medicine (IOM) released a report on the use of caffeine during sustained military operations in which recommendations for research and practice were made. Objective This systematic review serves as an update on the current quality of the evidence and addresses gaps in the current literature surrounding the effects of caffeinated foods and beverages on cognitive functioning in healthy adult populations exposed to military-like moderators. Data Sources PubMed, CINAHL, Embase, PsycInfo, and the Cochrane Library were searched. Study Selection Peer-reviewed randomized controlled trials published in the English language since 1998 were eligible. Data Extraction Twenty-five trials were included and assessed for methodological quality, and descriptive data were extracted according to each military-like moderator identified. Data Synthesis Moderators included sleep deprivation (n = 17), physical or mental exertion (n = 4), sleep deprivation combined with a sustained military operation (n = 3), and physical exertion combined with low ambient temperature (n = 1). Conclusions The effects of caffeine supplementation on cognitive functioning in sleep-deprived subjects included improvements in attention and vigilance, complex reaction time, and problem solving and reasoning in the trials reviewed. These findings are consistent with the conclusions reached in the 2001 IOM report. This review contributes to the field by addressing gaps outlined in the IOM report.

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
Natural health products (or dietary supplements) refer to those products found in oral dosage forms, containing 1 or more active ingredients considered to be a nutrient, an herbal product, or any other nonnutrient/nonherbal substance. Their use continues to increase in the general population and in patients seen by nutrition support clinicians. Aside from an appraisal of product safety and effectiveness, attention should be paid to the potential for these product ingredients to interact with medication. Estimates are that at least 15 million adults in the United States are at risk for supplement-drug interactions. These can occur through both pharmacokinetic and pharmacodynamic mechanisms. This review describes the influence of dietary supplements on both the disposition and the effect of medication and provides numerous examples. Patients at greatest risk for interactions are those with chronic disease, who use multiple medications-particularly those with a narrow therapeutic range-have genetic variants in drug metabolism, impaired organ function, and are at either end of the age spectrum. Knowledge of the specific effects on drug absorption, metabolism, and effect is still incomplete. Relative to the large number of possible interactions between supplements and medication, only a small number of combinations have been examined or reported. The greatest limiting factor remains the quality or reliability of the existing evidence, as many widely accepted interactions are only theoretical based either on in vitro data or known pharmacology. A distinction needs to be clearly drawn between "documented" interactions and "potential" interactions. Although drug-drug interactions have been widely recognized, supplement-drug interactions may be as important to recognize, report, and manage.

Abstract
Epilepsy is the most common chronic neurological disease, affecting about 1% of the world's population during their lifetime. Most people with epilepsy can attain a seizure-free life upon treatment with antiepileptic drugs (AEDs). Unfortunately, seizures in up to 30% do not respond to treatment. It is estimated that 90% of people with epilepsy live in developing countries, and most of them receive no drug treatment for the disease. This treatment gap has motivated investigations into the effects of plants that have been used by traditional healers all over the world to treat seizures. Extracts of hundreds of plants have been shown to exhibit anticonvulsant activity in phenotypic screens performed in experimental animals. Some of those extracts appear to exhibit anticonvulsant efficacy similar to that of synthetic AEDs. Dozens of plant-derived chemical compounds have similarly been shown to act as anticonvulsants in various in vivo and in vitro assays. To a significant degree, anticonvulsant effects of plant extracts can be attributed to widely distributed flavonoids, (furano)coumarins, phenylpropanoids, and terpenoids. Flavonoids and coumarins have been shown to interact with the benzodiazepine site of the GABAA receptor and various voltage-gated ion channels, which are targets of synthetic AEDs. Modulation of the activity of ligand-gated and voltage-gated ion channels provides an explanatory basis of the anticonvulsant effects of plant secondary metabolites. Many complex extracts and single plant-derived compounds exhibit antiinflammatory, neuroprotective, and cognition-enhancing activities that may be beneficial in the treatment of epilepsy. Thus, botanicals provide a base for target-oriented antiepileptic drug discovery and development. In the future, preclinical work should focus on the characterization of the effects of plant extracts and plant-derived compounds on well-defined targets rather than on phenotypic screening using in vivo animal models of acute seizures. At the same time, available data provide ample justification for clinical studies with selected standardized botanical extracts and plant-derived compounds. This article is part of a Special Issue entitled "Botanicals for Epilepsy".

Abstract
Epilepsy is one of the most common diseases affecting the nervous system, with more than 50 million patients suffering from epilepsy worldwide. Although epilepsy has been prevalent for thousands of years, it is still not possible to completely control the disease. Despite an increase in the number of available antiepileptic drugs, the incidence of epilepsy and its cure rate have not been substantially improved; thus, there is an urgent need to identify new drugs that treat, cure or protect against epilepsy. Resveratrol is a polyphenol compound with a broad range of biological activity; not only it has considerable antiepileptic effects, but it is also neuroprotective and has functions to counter epileptic depression. Resveratrol has the potential to be a new antiepileptic drug, thus further studies are needed to better investigate its potential.

Comparison of precipitating factors for mania and partial seizures: Indicative of shared pathophysiology? J Affect Disord 2015; 183:57-67. [PMID: 26001664 DOI: 10.1016/j.jad.2015.04.057] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2014] [Revised: 03/23/2015] [Accepted: 04/30/2015] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Mania in bipolar disorder (BD) and partial (focal) seizures (PS) arising from the temporal lobes, have a number of similarities. Typically, a chronic course of the disorders is punctuated by acute illness episodes. Common features of episodes may include sensory, perceptual, cognitive and affective changes. Both respond to anticonvulsant treatment. Common mechanisms imputed include neurotransmitters and kindling processes. Further investigation may improve understanding of the occurrence of both mania and PS, casting light on the relevance of temporal lobe mediated processes and pathology. One avenue of investigation is to compare aetiological factors and determine the extent of overlap which may indicate shared brain localization or pathophysiology. Aetiology includes predisposing, precipitating or perpetuating factors. This paper examines the literature on precipitating factors of mania, first or subsequent episode, and of PS in diagnosed epilepsy, which is the second or subsequent seizure, to identify the extent and nature of their overlap. METHOD Narrative review based on a literature search of PubMed and Google Scholar. RESULTS Precipitating factors for both mania and PS were stress, sleep deprivation, antidepressant medication and, tentatively, emotion. For mania alone, goal-attainment events, spring and summer season, postpartum, and drugs include steroids and stimulants. For PS alone, winter season, menstruation and specific triggers in complex reflex epilepsies. Those not substantiated include lunar phase and menopause. A wide range of chemicals may provoke isolated seizures but by definition epilepsy requires at least two seizures. CONCLUSIONS The overlap of precipitating factors in mania and PS imply that common brain processes may contribute to both, consistent with findings from neuroscience research.

Abstract
Epilepsy affects approximately 50 million people worldwide. Among them, at least 40 million people are currently living in the developing world, where resources and standards of care are suboptimal. Around 90 % of people with epilepsy in resource-poor countries do not currently receive appropriate treatments, at a time when two thirds of these patients could have achieved good control of their epileptic seizures had they had access to appropriate therapies. Scarcity of epilepsy specialists, poor availability or access to diagnostic facilities and treatments, poor community knowledge about epilepsy-related issues, stigma, and other societal and cultural barriers are only some of the issues contributing to this deficiency. These issues in epilepsy treatment have been well recognized, and ongoing concerted efforts to address them have been undertaken by both local authorities and international organizations. In many cases, patients resort to the use of traditional local and alternative medicines (herbs, religious practices, etc.) that are closer to indigenous cosmovision, are more holistic, and are more culture-friendly, preserving an optimum subtlety of Afrocentric character shading. Compared with imported Western medicines, patients find these approaches to be more relevant to their ways of thinking, their ways of being, and their belief systems, more accessible, and more acceptable methods of dealing with health and disease states. The impressive local wealth in these natural resources has established them as a preferred source of healing in these regions, but has also fueled interest in exploring their therapeutic potential in the very few existing local research centers. In this review, we discuss the known issues related to the epilepsy treatment gap in resource-poor regions, focusing in particular on African countries, introduce the role and issues related to the use and validation of alternative medical therapies in epilepsy, and comment on the importance and repercussions of initiatives to validate such therapies, primarily for local practices, but also for possible wider international applications.

Abstract
ABSTRACT:Background:Complementary and alternative medicine (CAM) is increasingly used in adults and children. Studies on CAM in neurological disorders have focused on the adult population and its use among pediatric neurology patients has not been well characterized.Objectives:The purpose of this study was: 1) To characterize the prevalence of CAM in pediatric neurology patients; 2) To determine the perceived effectiveness of CAM in these children; 3) To compare the cost of CAM with conventional therapies; and 4) To describe caregiver or patient-related variables associated with the use of CAM.Methods:This was a cross-sectional survey of patients and families attending the Alberta Children's Hospital neurology clinic between February and May 2004. Patients were considered eligible if they were between two and 18 years of age and had a known history of neurological disorders. Caregivers completed several self-administered questionnaires regarding their socio-demographic profile, their child's neurological illness, and their experience with CAM. Caregivers also rated their child's quality of life using the Pediatric Quality of Life Inventory.Results:One hundred and five of 228 (46%) families completed the survey. The mean age of the neurology patients was 9.8 ± 4.5 years. Forty-six (44%) out of 105 patients received one or more types of CAM, with the most common types being chiropractic manipulations (15%), dietary therapy (12%), herbal remedies (8%), homeopathy (8%), and prayer/faith healing (8%). Caregivers' sociodemographic variables or pediatric health-related quality of life were not significantly associated with the use of CAM. Fifty-nine percent of CAM users reported benefits, and only one patient experienced side effects. There was no significant difference in the total median cost of CAM compared to conventional therapies ($31.70 vs. $50.00 per month). Caregivers' personal experience or success stories from friends and media were common reasons for trying CAM.Conclusions:The use of CAM was common among pediatric neurology patients. Over half of the families reported benefits with CAM, and side effects were perceived to be few. Physicians should initiate discussion on CAM during clinic visits so that the families and patients can make informed decisions about using CAM. Further studies should address the specific role of CAM in children with neurological disorders, and to determine the potential interactions between CAM and conventional therapies in these patients.

Abstract
Opioid and ephedra alkaloids known as the active ingredients for Keke capsule, which is used to treat coughs and bronchial asthma, could have potential adverse effects on the central nervous system. Therefore, an efficient, sensitive rapid-resolution LC-MS/MS method for the simultaneous determination of morphine, ephedrine, and pseudoephedrine in rat plasma and brain tissue homogenate has been developed. The method was validated in the plasma and brain tissue samples, showed good linearity over a wide concentration range (r(2) > 0.99). The intra- and interday assay variability was less than 15% for all analytes, and the accuracy was between -8.8 and 5.7%. The study provided the pharmacokinetics profiles and the brain regional distribution of the three active alkaloids after oral administration of Keke capsule. The results also indicated that significant difference in pharmacokinetics parameters of the epimers was observed between ephedrine and pseudoephedrine.

Abstract
Herbs are staging a comeback and herbal 'renaissance' is happening all over the globe. The herbal products, today, symbolize safety, in contrast to the synthetics that are regarded as unsafe to humans and the environment. A herb, botanically speaking, is any plant that lacks the woody tissue which is characteristic of shrubs or trees. More specifically, herbs are plants which are used medicinally or for their flavour or scent. Herbs with medicinal properties are a useful and an effective source of treatment for various disease processes. Herbal extracts have been successfully used in dentistry as tooth cleaning and antimicrobial plaque agents. The use of herbal medicines continues to expand rapidly across the world. Many people take herbal medicines or herbal products now for their health care in different national healthcare settings. Herbal extracts have been used in dentistry for reducing inflammation, as antimicrobial plaque agents, for preventing release of histamine and as antiseptics, antioxidants, antimicrobials, antifungals, antibacterials, antivirals and analgesics. They also aid in healing and are effective in controlling microbial plaque in gingivitis and periodontitis, thereby improving immunity.

Abstract
Cigarette smokers have an increased risk for coronary artery disease. Nicotine present in cigarettes can adversely affect the cardiovascular system via stimulation of both sympathetic and parasympathetic neurons. Caffeine, another cardiovascular and central nervous system (CNS) stimulant, is commonly found in Ephedra and Ephedra-free dietary supplements. These caffeine-containing supplements also have been linked to cardiovascular toxicities. Although no longer on the U.S market, Ephedra-containing supplements are another source of cardiovascular and CNS stimulants, namely the ephedrine alkaloids. Together caffeine, nicotine, and ephedrine can individually stress the cardiovascular system, and an overlap of these agents is predicted in smokers and dieters. To understand the collective effects of these stimulants on the heart morphology and ultrastructure, rats were exposed to synthetic combinations of nicotine (0.2 mg/kg/day), ephedrine (0-30 mg/kg/day), and/or caffeine (0-24 mg/kg/day) as well as an extract from a caffeine-containing Ephedra supplement (Metabolife 356). After exposure for 3 days, the hearts were removed and examined for hypersensitivity myocarditis and myocardial necrosis. None of the drugs tested alone affected heart tissue morphology, nor were atypical cardiac cells observed. However, in combination, significant interactions were found between caffeine and ephedrine; the interventricular septum was most susceptible, with a significant increase in atypical cardiac cells observed. Nicotine pretreatment caused greater susceptibility to cardiotoxicity associated with combinations of caffeine + ephedrine or Metabolife, particularly in the left ventricle wall. These results indicate that sympathomimetic combinations present in Ephedra supplements may have produced cardiotoxicity reported in consumers of these products. Moreover, the presence of nicotine exacerbates these toxic effects.

Abstract
The anticonvulsant activity of the racemate and enantiomers of linalool have been evaluated. Pretreatment of the mice with ( S)-(+)-, ( R)-(-)- and rac-linalool increased the latency of convulsions significantly in the PTZ model. Only rac-linalool had an effect at the dose of 200 mg/kg. The enantiomers and their racemic mixture were effective in inhibiting the convulsant effect of PTZ at the dose of 300 mg/kg. The linalools presented pharmacological activity close to that of diazepam. In the PIC seizure model, ( R)-(-)-linalool and rac-linalool presented activity at the dose of 200 mg/kg, but the rac-linalool was more potent than ( R)-(-)-linalool; ( S)-(+)-linalool had no effect at this dose. On the other hand, at the dose of 300 mg/kg this enantiomer was effective, but less potent than ( R)-(-)-linalool and rac-linalool. In the MES model, linalools decreased the convulsion time of the mice in the doses of 200 and 300 mg/kg. rac-Linalool presented maximum effect at 300 mg/kg. Surprisingly, it increased significantly the convulsion time at a dose of 100 mg/kg. Using the parameter of tonic hind convulsions, only ( R)-(-)-linalool produced protection from tonic extension at the dose of 200 mg/kg. When the (+)- and (-)-enantiomers, and rac-linalool were administered at the dose of 300 mg/kg they were also effective in preventing tonic convulsions induced by transcorneal electroshock in the animals. The (+)- and (-)-forms were equipotent and the rac-linalool was more effective than phenytoin. We have demonstrated that the two enantiomers have similar qualitative anticonvulsant activity, but show different potencies.

Abstract
Annonas are consumed as fresh fruits, but, because of their effects on the central nervous system, are also used in folk medicine. The effect on rat amygdala kindling of repeated administration of Annona diversifolia hexane (100mg/kg IP or PO) and ethanol (100mg/kg, PO) leaf extracts and palmitone (10mg/kg, IP) was determined. Electrographic and/or behavioral changes were monitored during kindling-induced seizures 60minutes after treatments. Antiepileptic efficacy was evaluated with respect to afterdischarge (AD) duration, spike frequency, and/or behavioral seizure activity. Oral administration of both extracts significantly decreased spike frequency, whereas intraperitoneally administered hexane extract and palmitone only reduced AD duration. Hexane extract and palmitone exhibited anticonvulsant properties and delayed establishment of a kindling state as observed with diazepam (0.3mg/kg IP). These results reinforce the anticonvulsant properties of this plant, and palmitone and other constituents are responsible for the pharmacological effects.

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
Background The use of complementary and alternative medicine (CAM) is on the increase globally with a high prevalence in children and adults with chronic illnesses. Many studies have evaluated the epidemiology of medicine use for children in developing countries but none has evaluated the use of CAM for children with chronic illnesses. The aim of this study was therefore to determine the prevalence, pattern of use, parental sources of information, perceived benefits, cost, and adverse effects of CAM in children with epilepsy, sickle cell anaemia and asthma in Lagos, Nigeria. Methods Parents of children with epilepsy (122), asthma (78) or sickle cell anaemia (118) who presented consecutively to the paediatric neurology, respiratory and haematology clinics of the Lagos State University Teaching Hospital (LASUTH), Ikeja were interviewed with a structured open- and close-ended questionnaire. The information obtained comprised the demography of both the patients and their parents; past and present treatments received by the patients; the type of CAM, if any, used by the patients; and the sources, cost, benefits and adverse effects of the CAM used. Results A total of 303 CAMs were used by the patients, either alone or in combination witother CAM. CAM was reportedly used by 99 (31%) patients (epilepsy -38%, sickle cell anaemia – 36% and asthma – 25%). The majority (84%) of these patients were currently using CAM. The use of CAM was stopped six months prior to the study by 16 patients (16%). Biological products were the most frequently used CAMs (58%), followed by alternative medical systems (27%) and mind-body interventions (14%). Relations, friends and neighbours had a marked influence on 76% of the parents who used CAM for their children. Eighty-five (86%) parents were willing to discuss the use of CAM with their doctors but were not asked. CAM use was associated with adverse reactions in 7.1% of the patients. Conclusion Parental use of CAMs to treat their children with epilepsy, asthma and sickle cell anaemia is common in Nigeria. Efforts should be made by doctors taking care of these patients to identify those CAM therapies that are beneficial, harmless and cheap for possible integration with conventional therapy.

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
OBJECTIVE The use of herbals and health supplements is not without risk. This case report of a 17-year-old girl who presented with acute dural sinus thrombosis following herbal tonic ingestion illustrates the dangers of unsupervised ingestion of "health supplements." SUBJECT AND METHODS A 17-year-old girl with normal menses and no prior medical history, procoagulant risk factors, or oral contraceptives use, presented following ingestion of herbal liquid for 2 days, with signs and symptoms of dural sinus thrombosis confirmed by CT scan. MRI and MRV showed bilateral transverse sinuses thrombosis. The patient had an extensive workup, and all procoagulant disorders or factors, including Behcet's disease, were ruled out. The temporal profile of the ingestion of herbal fluid may suggest association with the development of sinus thrombosis. CONCLUSION Combinations of herbs in dietary or health supplements could potentiate their subclinical procoagulant effects, and this case highlights the need to report such serious central nervous system adverse effects associated with the ingestion of herbal preparations.

Abstract
BACKGROUND Plant-derived botanical and dietary supplements are widely self-prescribed in the US and considered natural, safe, and beneficial. However, because they are not strictly regulated by the Food and Drug Administration (FDA), their ingredients are not always known and they may contain unexpected agents. Among the myriad plant-produced molecules are flavonoids, which reportedly have various human health effects, including anticancer, antioxidant, and estrogenic properties. Several flavonoids (eg, isoflavones) are known as phytoestrogens, based on their ability to mimic estrogen in mammals. Because botanical and dietary supplements are plant products and need not be processed or purified due to their FDA classification as foods, they may contain unexpected phytoestrogens, such as flavonoids. OBJECTIVE To analyze 8 botanical and 11 ephedra-containing dietary supplements for the presence and concentration of 5 flavonoids (biochanin A, daidzein, formononetin, genistein, quercetin), which may deliver unexpected estrogenic activity. METHOD Randomly selected tablets from single bottles of 19 botanical and dietary supplements purchased locally were pooled. Flavonoids were extracted into ethanolic solution and analyzed by high-performance liquid chromatography. RESULTS Flavonoids were detected in all supplements tested, with the largest number (4) found in Kava Kava. Almost all supplements contained measurable amounts of genistein and/or daidzein, known estrogenic agents, at up to 22 mg/day of isoflavone, per recommended daily dosage of supplement. CONCLUSIONS These results suggest that single-component botanical and multi-ingredient dietary supplements could contain unexpected estrogenic agents, which may impact the health of consumers.

Abstract
Complementary and alternative medicine (CAM) is a multibillion-dollar industry. Almost half of the American population uses some form of CAM, with many using them in addition to prescription medications. Most patients fail to inform their health care providers of their CAM use, and physicians rarely inquire. Annually, thousands of dietary supplement-induced adverse events are reported to Poison Control Centers nationwide. CAM manufacturers are not responsible for proving safety and efficacy, because the Food and Drug Administration does not regulate them. However, concern exists surrounding the safety of CAM. A literature search using MEDLINE and EMBASE was undertaken to explore the impact of CAM on renal function. English-language studies and case reports were selected for inclusion but were limited to those that consisted of human subjects, both adult and pediatric. This review provides details on dietary supplements that have been associated with renal dysfunction and focuses on 17 dietary supplements that have been associated with direct renal injury, CAM-induced immune-mediated nephrotoxicity, nephrolithiasis, rhabdomyolysis with acute renal injury, and hepatorenal syndrome. It is concluded that it is imperative that use of dietary supplements be monitored closely in all patients. Health care practitioners must take an active role in identifying patients who are using CAM and provide appropriate patient education.

Abstract
Over the last two decades, there has been a rapid expansion in the number and types of available antiepileptic drugs (AEDs), but there is increasing concern amongst parents and carers about their unwanted side effects. Seizure control is achieved in approximately 75% of children treated with conventional AEDs, but non-conventional (or non-standard) medical treatments, surgical procedures, dietary approaches, and other non-pharmacological treatment approaches may have a role to play in those with intractable seizures or AED toxicity. Many of the approaches are largely common sense and are already incorporated into our current practice, including, for example, avoidance techniques and lifestyle advice, while others require further investigation or appear to be impractical in children.

Abstract
Complementary and alternative medicine (CAM) has become much in vogue, and CAM practitioners have increased in tandem with this. The trend of using CAM for treating epilepsy does not differ from that in other medical conditions, with nearly one half of patients using CAM. In this article we review the major complementary and alternative medicines used for treatment of epilepsy. They include mind-body medicines such as reiki and yoga; biologic-based medicine such as herbal remedies, dietary supplements, and homeopathy; and manipulative-based medicine such as chiropractic. In the available literature, there is a sense of the merit of these therapies in epilepsy, but there is a paucity of research in these areas. Individualized therapies such as homeopathy and reiki cannot be compared with medicines in a conventional pharmaceutical model. Hence, many studies are inconclusive. In a science of double-blind, randomized controlled trials, appropriate designs and outcome measurements need to be tailored to CAM. This article explains the principles of the major CAM therapies in epilepsy, and discusses peer-reviewed literature where available. More effort needs to be put into future trials, with the assistance of qualified CAM professionals to ensure conformation to their therapeutic principles.

Abstract
PURPOSE The metal content of dietary supplements, including 13 ephedra-containing supplements, was studied. METHODS Samples of botanicals (black cohosh, echinacea, goldenseal, kava kava, milk thistle, saw palmetto, Synephrine, and valerian root), ephedra-containing dietary supplements (Amp II, EPH 833, Ephedra, Ephedra 1000, Hydroxycut, Metabolife 356, Metabolift, Ripped Fuel, Ripped Fuel Extreme, Ripped Fuel [ma huang-free], Stacker 2 [two lots], Super Stinger, Virgin Earth, Xenadrine RFA-1 [two lots], Yellow Jacket), and nonprescription reference agents (NoDoz and Primatene) were digested in acid, reacidified, and then spiked with internal standards. Metals were quantified using Environmental Protection Agency quality assurance and quality-control standards 6020 and 200.8. Forty-seven metals were analyzed by inductively coupled plasma-mass spectrometry, with subpart-per-trillion detection limits. RESULTS All metals detected were in concentrations below toxic levels or physiological limit levels for the daily doses specified by the products' labeling. Metals found in highest concentrations among all the supplements sampled were sodium, magnesium, calcium, potassium, aluminum, iron, titanium, mercury, strontium, lead, barium, and silver. Of the 27 supplements analyzed, those with the lowest metal concentrations were mostly single-ingredient botanical supplements, while multiple-component, ephedra-containing dietary supplements generally had higher metal concentrations. Significant lot-to-lot variations were found for two ephedra-containing dietary supplements. CONCLUSION None of 47 metals was found in highly toxic amounts in 23 brands of dietary supplements and two nonprescription reference preparations.

Abstract
Drug- and toxin-associated seizures (DTS) may result from exposure to a wide variety of agents. Most DTS can be managed with supportive care. First-line anticonvulsant therapy should include benzodiazepines, unless agents require a specific antidote. Phenytoin is generally not expected to be useful for DTS and in some instances may be harmful. In this article the authors discuss the pathophysiology of DTS, the potential differential diagnosis, and the clinical presentation. They also review selected agents that cause DTS and provide an overview of how the clinician should approach the management of patients who have DTS.

Abstract
Drug- and toxin-associated seizures may result from exposure to a wide variety of agents. Obtaining a comprehensive history behind the exposure is generally more helpful than diagnostic testing. Most DTS may be managed with supportive care, including benzodiazepines, except in the case of agents that require a specific intervention or antidote.

Abstract
The purpose of this paper is to explore the possibility that adverse reactions and drug interactions arising from the use of homeopathic and herbal medicines could lead to confusion when adverse reactions to conventional medicines are reported. An extensive literature review was conducted on the occurrence of adverse reactions and drug interactions following the use of homeopathic or herbal remedies, and the potential for these to confound adverse event reporting to conventional medicines considered. The survey demonstrates the potential for herbal remedies and homeopathic products, to produce adverse drug reactions or drug interactions, and shows the scope for potential for confusion with those arising from conventional medicines. There is a need for greater awareness that adverse reactions apparently due to a conventional medicine, might in reality be due to a herbal medicine or a drug interaction between a herbal medicine and a conventional drug, particularly when a health professional is unaware of the extent of a patient's self-medication with alternative therapies.

Abstract
Yukmijihwang-tang (YMJ), also known as Luweidihuang-tang in China, has been widely used as a general herbal tonic for hundreds of years in many Asian countries. This study examines whether YMJ derivatives (YMJd) enhance cognitive ability in normal human subjects and discusses its potential as treatment for dementia patients with deficient cognitive ability. Subjects were divided into two groups, the placebo-treated group (n = 15) and the YMJd-treated group (n = 20). K-WAIS tests, a Korean version of an individual intelligence quotient (IQ) test, and a P300 latency assessment of event-related potential (ERP) were conducted in order to measure changes in cognitive ability before and after 6 weeks of YMJd treatment. The K-WAIS mean scores of the group treated with YMJd were significantly higher than those of the placebo group (p < 0.05), and their mean P300 latency was substantially shorter (p < 0.005). These results suggest that YMJd treatment accelerates the speed of information processing and enhances cognitive ability. YMJd treatment may help dementia patients or the elderly recover from cognition deficiencies or degeneration in clinic.

Abstract
Complementary and alternative medicines (CAMs) are increasingly used by patients in the Western world. Some of the most popular herbal remedies are known to act on the cytochrome P450 system, with potential effects on antiepileptic drug (AED) levels. Few studies have explored their use in people with epilepsy. We surveyed 400 patients attending epilepsy clinics in Greater Manchester. Thirty-four percent of our patients had used or were using CAMs; the majority had not told their doctor. Use of CAMs was not predicted by age, sex, seizure frequency, number of AEDs, or dissatisfaction with conventional medicine. Patients who had gone onto higher education were significantly (P < 0.05) more likely to have used or be using CAMs. The majority of patients did not use CAMs for their epilepsy but for general health purposes. Most patients stated that CAMs had little or no effect on seizure frequency or severity.

Abstract
The herbal extract Yukmijihwang-tang (YMJ) has been widely used for centuries as an anti-aging herbal medicine in Asian countries. Among the various modified prescriptions of YMJ, YMJ derivatives (YMJd) were formulated to enhance memory retention. This study has three goals: 1) to quantitatively evaluate the memory-enhancing effect of YMJd using behavior tasks; 2) to use cDNA micro-array tools to identify candidate genes responsible for enhancing memory; and 3) to statistically evaluate the specific gene expression patterns using Real-time PCR. Memory retention abilities are addressed by the passive avoidance task with SD male rat. The retention time of the YMJd group was significantly delayed (ca. 100%), whereas with Ginkgo biloba and Soya lecithin treatment, this was only delayed 20% and 10%, respectively. The cDNA from the hippocampi of YMJd and rat control groups were applied to an Incyte rat GEM2 cDNA microarray. The microarray results showed that transthyretin and PEP-19 were abundantly expressed in the YMJd treated group. Importantly, PEP-19 is a neuron-specific protein that inhibits apoptotic processes. On the other hand, neuronal genes involved in neuronal death or neurodegeneration, such as pentraxin and spectrin, were abundantly expressed in the control group. The list of differentially expressed genes may provide further insight into the action and mechanism behind the memory-enhancing effect of herbal extracts of YMJd.

Abstract
Behavioral risk factors associated with comorbidity in people with epilepsy are largely unknown. We studied a population-based sample of 8057 adults through the 2002 Behavioral Risk Factor Surveillance System, in Georgia and Tennessee, ascertaining a lifetime epilepsy prevalence of 2.1% in this population. This structured interview revealed that those with epilepsy had significantly worse self-reported fair or poor health status (39% vs 17% in adults without epilepsy), significantly greater cigarette smoking (38.8% vs 24.9% in other adults), and high rates of obesity (34.1% vs 23.7% in adults without epilepsy). Large percentages of adults with epilepsy reported currently symptomatic asthma and recent joint pain. Adults with epilepsy had lower educational attainment and lower household incomes, but a higher rate of medical insurance coverage, than did other adults. This type of population-based survey can serve to identify health disparities, behavioral risk factors for other chronic diseases, and unmet health care needs in individuals with epilepsy, and to track changes in these measures over time.
