They are age-related, without demonstrable anatomic lesions, and are subject to spontaneous remission. Clinically, patients have neither neurologic and intellectual deficit nor a history of antecedent illness, but frequently have a family history of benign epilepsy. The seizures are usually brief and rare, but may be frequent early in the course of the disorder. The seizure patterns may vary from case to case, but usually remain constant in the same child. This includes not only patients with small circumscribed constant epileptogenic lesions (anatomic or functional), that is, true focal epilepsies, but also patients with less well-defined lesions, whose seizures may originate from variable loci. In most symptomatic localization-related epilepsies, the epileptogenic lesions can be traced to one part of one cerebral hemisphere, but in idiopathic age-related epilepsies with focal seizures, corresponding regions of both hemispheres may be functionally involved. Childhood Epilepsy with Occipital Paroxysms the syndrome of childhood epilepsy with occipital paroxysms is, in general respects, similar to that of benign childhood epilepsy with centrotemporal spikes. The seizures start with visual symptoms (amaurosis, phosphenes, illusions, or hallucinations) and are often followed by a hemiclonic seizure or automatisms. During seizures, the occipital discharge may spread to the central or temporal region. Generalized Epilepsies and Syndromes According to the International Classification of Epilepsies and Epileptic Syndromes, generalized epilepsies and syndromes are epileptic disorders with generalized seizures, that is, "seizures in which the first clinical changes indicate initial involvement of both hemispheres. The patient usually has a normal interictal state, without neurologic or neuroradiologic signs. The various Chapter 18: Classification of the Epilepsies 239 syndromes of idiopathic generalized epilepsies differ mainly in age of onset. If other seizures occur, they are mostly absence or myoclonic, as in juvenile myoclonic epilepsy. Benign Neonatal Convulsions Benign neonatal convulsions are very frequently repeated clonic or apneic seizures occurring at about the fifth day of life, without known etiology or concomitant metabolic disturbance. There is no recurrence of seizures, and the psychomotor development is not affected. Benign Myoclonic Epilepsy in Infancy Benign myoclonic epilepsy in infancy is characterized by brief bursts of generalized myoclonus that occur during the first or second year of life in otherwise normal children who often have a family history of convulsions or epilepsy.

The evidence presented is too slim to make any specific recommendations regarding concurrent use. Mu Y, Zhang J, Zhang S, Zhou H-H, Toma D, Ren S, Huang L, Yaramus M, Baum A, Venkataramanan R, Xie W. Traditional Chinese medicines Wu Wei Zi (Schisandra chinensis Baill) and Gan Cao (Glycyrrhiza uralensis Fisch) activate pregnane X receptor and increase warfarin clearance in rats. Liquorice + Warfarin the interaction between liquorice and warfarin is based on experimental evidence only. Constituents Lycium fruit contains carotenoids such as betacarotene and zeaxanthin, beta-sitosterol, linoleic acid, betaine and various polysaccharides, vitamins and amino acids. Interactions overview Lycium has antidiabetic effects, which may be additive to conventional antidiabetics, although evidence for this is largely experimental. Use and indications Lycium (dried berries or root bark) has been used to treat diabetes, ophthalmic disorders, hypertension and erectile dysfunction, and is thought to possess anti-inflammatory, antioxidant and anticancer properties. L 277 278 Lycium Lycium + Antidiabetics the interaction between lycium and antidiabetics is based on experimental evidence only. Experimental evidence In an experimental study in rats with streptozotocin-induced type 2 diabetes,1 Lycium barbarum polysaccharide (extracted from the fruit of lycium) decreased insulin resistance, and reduced fasting insulin and postprandial glucose levels. In another study, a fruit extract of Lycium barbarum 10 mg/kg twice daily for 10 days significantly reduced blood-glucose levels in diabetic rabbits but did not reduce blood-glucose levels in healthy mice. Importance and management the evidence is limited and purely experimental but what there is suggests that lycium may have antidiabetic properties. Therefore, there is a theoretical possibility that lycium may enhance the bloodglucose-lowering effects of conventional antidiabetics. However, until more is known, it would be unwise to advise anything other than general caution. Hypoglycemic and hypolipidemic effects and antioxidant activity of fruit extracts from Lycium barbarum.

An interpretation, stating the overall impressions gained from, and clinical significance of, the electrographic and behavioral correlations. This portion of the report should be an interpretive synthesis rather than a reiteration of the description. Overall pathophysiological and diagnostic formulations should include reference to available data on the quantitative and topographic features of interictal epileptiform and nonepileptiform, as well as ictal, abnormalities. Inferences as to the site of origin and propagation of seizures should be made when this is justified by the findings. The purpose of this phenomenological study was to contribute to the existing literature by identifying the perceptions and school experiences of a small group of children with epilepsy. Through the process of journal writing, the researcher implemented bracketing as a means of eliminating presuppositions of the phenomenon so that its essence can emerge without influence from existing theories, research findings, or personal biases (Ashworth, 1999). Although the researcher bracketed her presuppositions, findings continue to be subjective, and are therefore not generalizable, but are instead specific to the children in this study. Throughout the study, interview discussions were recorded, extensively reviewed, and transcribed. Transcripts were coded for meaning units and themes (Creswell, 1998, 2005; Donalek, 2004). Participants were then asked to validate the emergent themes to confirm the truth-value of the interpretation (Donalek, 2004; Roberts & Cairns, 1999). The researcher continued to use a journal to reflect on her thoughts, responses, and decision-making process to establish credibility. Each participant had been diagnosed with epilepsy and was enrolled in school located in the Victoria, British Columbia region. At the time of the interview, three participants were enrolled in public schools, two attended private schools, and one was home-schooled. These children experienced absence, tonic clonic, or complex partial seizures (Table 1).

In situations where discordant information is obtained, or poorly defined epileptogenic areas are found in noninvasive testing, or in cases of close proximity of the epileptogenic zone to eloquent cortex, the need from chronically implantable invasive electrodes becomes an acceptable alternative. The success of epilepsy surgery depends on the identification of a focal epileptogenic zone and invasive recordings may offer in-depth evaluation for patients that may otherwise have no other option. Intracranial electrodes overcome the sensitivity limitations of extracranial electrodes because they are closer to the cortical focus and free of the dampening effect of the skull and scalp. This increased sensitivity, however, is at the expense of more restricted sampling, or "vision," and involves an enhanced risk of complications. A thin electrode wire is introduced into the subtemporal fossa within a 22-gauge lumbar puncture needle. After the needle is inserted to a depth of 3 to 5 cm, the cannula is withdrawn and the wire is left in place. The wire is looped and taped into place on the cheek, and the distal end soldered to connectors for use in the electrode jackbox. For this reason, intracranial electrodes should be used only after noninvasive testing. The strength of the hypothesis (based on the results of the noninvasive evaluation) is a key to successful use of invasive techniques. The clearer the question formulated for testing, the greater the chance of success with the invasive evaluation. Chapter 81: Intracranial Electroencephalography and Localization Studies 915 this chapter provides an overview of the invasive techniques available for these difficult cases, and reviews the major clinical situations and how they can be approached. Modern computer-assisted image-based stereotaxy has greatly improved the ease and precision of depth electrode placement. A common approach for patients with suspected bitemporal epilepsy uses three electrodes placed under stereotaxis guidance, each with eight contacts that are advanced transversely through punctures in the middle or inferior temporal gyri into the amygdala and anterior and posterior hippocampus on each side. These allow the survey of electrical activity from the mesial structures, from infolded gray matter of basal temporal gyri, and from the lateral temporal lobe. An alternative trajectory for the evaluation of mesial temporal epilepsy is the longitudinal placement of depth electrodes by way of occipital burr holes (10,11).

It is not clear whether we will be able to identify a therapy that will provide a greater level of efficacy in this patient population using the current approach. As such, there is a clear need to move beyond the conventional animal models and to explore other animal models and molecular targets by which neuronal hyperexcitability may be reduced. Levetiracetam demonstrated that a new therapy does not have to be effective in the traditional seizure models to be effective in the patient with epilepsy. This implies that the community interested in developing a drug for this patient population will need to take a substantial risk when advancing a novel drug into a clinical trial. Only then will we likely find a therapy that provides the level of efficacy for which patients continue to hope.

One retrospective study limited to adolescents with adolescent-onset seizures reported a recurrence rate of 49% (71). The timing of recurrence is similar in studies of both children and adults and is independent of the absolute recurrence risk. One series in adults reported that 68% of relapses were during drug withdrawal and an additional 24% occurred during the first year after discontinuation of treatment (70). There is no secondary peak in recurrence risk years after discontinuing medications. Etiology and Neurologic Status Patients with remote symptomatic epilepsy associated with a prior neurologic insult, congenital malformation, motor handicap, brain tumor, mental retardation, progressive metabolic disease, trauma, or stroke are less likely to attain complete seizure control than are those with cryptogenic or idiopathic epilepsy (41,44,48). In one study of 264 children and adolescents, the cumulative recurrence risk 2 years following withdrawal of medications was 26% in the cryptogenic group and 42% in the neurologically abnormal group (P 0. The severity of mental retardation was an additional prognostic factor within this group. A recent study of the prognosis of epilepsy in children with cerebral palsy and epilepsy (56) found that the majority of these children did not achieve remission. However, of the 69 children who achieved a 2-year seizure remission and had their medication withdrawn, 58% remained seizurefree. With one exception (66), studies that did not find such an association either had very few (74) remote symptomatic cases or were restricted to those with cryptogenic epilepsy (55,67,70,78,80). A meta-analysis estimated the relative risk of recurrence in those with remote symptomatic epilepsy compared with cryptogenic epilepsy to be 1. This applies to all remote symptomatic causes including both mental retardation and cerebral palsy. Within Chapter 43: Initiation and Discontinuation of Antiepileptic Drugs 531 the remote symptomatic group, those with severe mental retardation have the highest recurrence risk (73). The discussion that follows focuses on differences within the pediatric age group. This corresponds to the known higher remission rates in the younger group (41,44,84).

One study of zonisamide in patients with mania and acute psychotic conditions indicated that 71% responded at least moderately to treatment (69). In an open-label trial of zonisamide in 35 patients with neuropathic pain, mean pain scores showed little or no improvement after 8 weeks of therapy (70). A trial in nine patients with Parkinson disease demonstrated that seven of the nine patients had improvement in their symptoms, especially wearing-off phenomenon, when zonisamide was added to their other medications (71). Preliminary data suggest that zonisamide is at least as effective as propranolol in patients with head tremor or essential tremor (14,72). Dizziness, somnolence, anorexia, abnormal thinking, ataxia, and confusion were more common with zonisamide compared to placebo. A meta-analysis, which calculated the odds ratios of adverse events reported in clinical trials, showed that patients on zonisamide were more likely to experience anorexia, ataxia, dizziness, and fatigue compared to patients receiving placebo (52). Monotherapy of Monotherapy Few clinical trials have evaluated the use of zonisamide in monotherapy for the treatment of epilepsy. When zonisamide is used by itself in children, the only adverse effect that occurs in 10% of individuals is somnolence (39). In some of these studies, this translated into a definite weight loss for many of the patients. A post hoc analysis of data from the major clinical trials demonstrated that significantly more patients on zonisamide (21. As a follow-up to the weight-loss effects, a double-blind, placebo-controlled study of 60 obese nonepileptic patients demonstrated a mean weight loss of 9. Women who took zonisamide had an additional 5 pounds weight loss compared to those only on a diet. Rare Adverse Effects Early in the clinical trials of zonisamide, the formation of renal calculi was observed in some patients (55). Four patients of the 113 enrolled in this study had kidney stones form during the study. Kubota reported three cases of nephrolithiasis in patients receiving zonisamide (76) and Miyamoto reported the case of a 10-year-old girl with a kidney stone after starting zonisamide (77). Some have speculated that renal calculi formation is related to inhibition of carbonic anhydrase by zonisamide.

If you have a Medical Home, the behavioral health specialists may work as part of the team or be located in the same facility. If there is not a Medical Home, your physician or other contact person can refer you to a knowledgeable practitioner. The behavioral health specialist may work in an office building close to you, or may work in a medical facility. Your contact person should take into account how far you will have to travel to see the behavioral health specialist, since these appointments usually occur on a frequent (often weekly) basis for a period of time. Also think about things that are special strengths of your child, since the description of your child should include strengths as well as needs. Try to be as specific as possible about how you would like things to look when change has occurred. Patient and Family Advocacy: the key role of the family is being the champion for your child, since nobody knows your child better. In the case of children and youth with epilepsy, many of the medications have side effects that can seriously affect quality of life. The family should note all of the side effects and communicate them effectively to the physician, so the family, the patient and the physician can make the best decision for the patient. There are many family- and patient-centered groups focused on advocating for the different needs of patients with epilepsy: medicalhomeinfo. When a child is newly diagnosed with epilepsy, it can be very overwhelming; having support from different community organizations and parents who have a child who was diagnosed with epilepsy and is now under control can make an important difference in the life of a child and the family. Before every medical or specialty visit, it is important to think about your goals for the visit: 1. Write all the questions that you want to ask your doctor and let the doctor know that you want these questions answered. If the medication has to be taken at school, have you filled out a seizure action plan for the school It is very important that all the key providers are informed and ready to help your child.

When zonisamide is used in children, parents should be instructed to carefully monitor for decreased sweating and increased body temperature. Children on zonisamide should not be exposed for prolonged periods of time to extreme heat. Individuals with impaired pulmonary or renal function are especially at risk for this side effect, and serum electrolytes should be monitored. Zonisamide doses were calculated to maintain plasma concentrations of 15 to 40 g/mL, and a battery of neuropsychological tests were administered prior to starting and after 12 weeks of zonisamide therapy. When plasma concentrations of zonisamide exceeded 30 g/mL the acquisition and consolidation of new information, especially verbal learning, were impaired. There were significantly more men than women with psychosis, and this group was younger than the general population of patients with epilepsy. Hirai and colleagues reported on 27 children in a prospective clinical trial of zonisamide monotherapy and two displayed behavioral disturbances (82). It is difficult to truly assess the incidence of these effects, because none of the reports accounted for the number of individuals taking zonisamide. Chapter 59: Zonisamide 729 Few data are available on the teratogenic effects of zonisamide. Only two women exposed to zonisamide during pregnancy bore children with major malformations. Zonisamide has been used in a variety of age groups, seizure types, and as monotherapy. The adverse effect and pharmacokinetic profile of zonisamide is favorable with few severe adverse effects reported and a long half-life that allows once-daily dosing.

Corticosterone secretion-inducing activity of saikosaponin metabolites formed in the alimentary tract. Constituents of some Chinese herbal medicines containing bupleurum Proportion of herbs in the medicines (parts) Sho-saiko-to1 Sairei-to2 Saiko-ka-ryukotsuborei-to3 Constituents Bupleurum root contains a range of triterpene saponins, the saikosaponins and saikogenins. Use and indications Bupleurum is used for chills, fevers, as an anti-inflammatory and general tonic. Anti-inflammatory and immune-modulatory activities have been demonstrated in laboratory tests. Bupleurum root is an ingredient of a number of traditional Chinese and Japanese herbal medicines such as Sho-saiko-to (Xiao Chai Hu Tang) and Sairei-to, see the table Constituents of some Chinese herbal medicines containing bupleurum opposite. Pharmacokinetics Saikosaponin a, and its monoglycoside and aglycones, were detectable in the plasma of rats when saikosaponin a was given orally. Absorption of other derivatives, structural isomers and their monoglycosides and aglycones, which were formed in the gastrointestinal tract, depended on food intake. The pharmacological effects of saikosaponin a given orally may therefore differ depending on conditions of the gastrointestinal tract. A study in rats to determine which of these metabolites are active, based on their corticosterone-secreting activity, found that saikosaponin a, saikosaponin d and their intestinal metabolites prosaikogenin F and prosaikogenin G showed strong activity. Other compounds and metabolites showed varying degrees of biological activity so the degree to which metabolism occurs is likely to affect pharmacological and clinical effects. Bupleurum is the main constituent of a number of Chinese herbal medicines, such as sho-saiko-to, saiko-ka-ryukotsu-borei-to and sairei-to. Neither sho-saiko-to nor sairei-to appears to alter the pharmacokinetics of ofloxacin. Sho-saiko-to may modestly affect the absorption of tolbutamide but blood-glucose levels appear to be minimally affected.
