Abstract
BACKGROUND The ketogenic diet (KD) is a high fat, moderate protein and very low carbohydrate diet. It can be used as a medical treatment for drug-resistant epilepsy (DRE), glucose transporter 1 deficiency syndrome and pyruvate dehydrogenase deficiency. The aim of this scoping review was to map the KD literature, with a focus on epilepsy and associated metabolic conditions, to summarise the current evidence-base and identify any gaps. METHODS This review was conducted using JBI scoping review methodological guidance and the PRISMA extension for scoping reviews reporting guidance. A comprehensive literature search was conducted in September 2021 and updated in February 2024 using MEDLINE, CINAHL, AMED, EmBASE, CAB Abstracts, Scopus and Food Science Source databases. RESULTS The initial search yielded 2721 studies and ultimately, data were extracted from 320 studies that fulfilled inclusion criteria for the review. There were five qualitative studies, and the remainder were quantitative, including 23 randomised controlled trials (RCTs) and seven quasi-experimental studies. The USA published the highest number of KD studies followed by China, South Korea and the UK. Most studies focused on the classical KD and DRE. The studies key findings suggest that the KD is efficacious, safe and tolerable. CONCLUSIONS There are opportunities available to expand the scope of future KD research, particularly to conduct high-quality RCTs and further qualitative research focused on the child's needs and family support to improve the effectiveness of KDs.

Abstract
In 2003, the first case series of six patients treated with an Atkins diet for epilepsy was published in the journal Neurology. The concept was a simple, outpatient-initiated diet in which ketosis could be maintained by eating high-fat foods while tracking and limiting daily carbohydrate counts based on food ingredient labels. Twenty years later, after dozens of studies encompassing hundreds of patients, including several randomized controlled trials, the Modified Atkins Diet is a proven method of providing ketogenic dietary therapy for epilepsy. It is a diet therapy of choice for adolescents and adults, is being investigated for new-onset epilepsy, and is researched for neurological conditions other than epilepsy. Adverse effects do exist but may be less common than the classic ketogenic diet. This review will cover the history, clinical trials, implementation, current utilization, and future directions of this "alternative" ketogenic diet therapy on its 20-year anniversary.

Front Neurol 2023; 14:1134827. [PMID: 37122314 PMCID: PMC10133555 DOI: 10.3389/fneur.2023.1134827] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Accepted: 03/27/2023] [Indexed: 05/02/2023] Open
Abstract
Background and purpose Ketogenic diet (KD) is an emerging treatment option for super-refractory status epilepticus (SRSE). We evaluated the effectiveness of KD in patients presenting SRSE including NORSE (and its subcategory FIRES). Methods A retrospective review of the medical records was performed at the Necker Enfants Malades Hospital. All children with SRSE in whom KD was started during the last 10 years were included. A systematic search was carried out for all study designs, including at least one patient of any age with SRSE in whom KD was started. The primary outcome was the responder rate and Kaplan-Meier survival curves were generated for the time-to-KD response. As secondary outcomes, Cox proportional hazard models were created to assess the impact of NORSE-related factors on KD efficacy. Results Sixteen children received KD for treatment of SRSE, and three had NORSE presentation (one infectious etiology, two FIRES). In medical literature, 1,613 records were initially identified, and 75 were selected for review. We selected 276 patients receiving KD during SRSE. The most common etiology of SRSE was acute symptomatic (21.3%), among these patients, 67.7% presented with NORSE of immune and infectious etiologies. Other etiologies were remote symptomatic (6.8%), progressive symptomatic (6.1%), and SE in defined electroclinical syndromes (14.8%), including two patients with genetic etiology and NORSE presentation. The etiology was unknown in 50.7% of the patients presenting with cryptogenic NORSE, of which 102 presented with FIRES. Overall, most patients with NORSE benefit from KD (p < 0.004), but they needed a longer time to achieve RSE resolution after starting KD compared with other non-NORSE SRSE (p = 0.001). The response to KD in the NORSE group with identified etiology compared to the cryptogenic NORSE was significantly higher (p = 0.01), and the time to achieve SE resolution after starting KD was shorter (p = 0.04). Conclusions The search for underlying etiology should help to a better-targeted therapy. KD can have good efficacy in NORSE; however, the time to achieve SE resolution seems to be longer in cryptogenic cases. These findings highlight the therapeutic role of KD in NORSE, even though this favorable response needs to be better confirmed in prospective controlled studies.

Abstract
AbstractSuper-refractory status epilepticus (SRSE) is a serious and life-threatening neurological condition. Ketogenic diet (KD) is a diet characterized by high fat, low carbohydrate, and moderate protein. As KD shows effectiveness in controlling seizures in more than half of SRSE patients, it can be a treatment option for SRSE. Currently, KD treatment for SRSE is based on personal experience and observational evidence has been published. In the context of a lack of a validated guideline, we convened a multicenter expert panel within the China Association Against Epilepsy (CAAE) Ketogenic Diet Commission to work out the Chinese expert recommendations on KD for SRSE. We summarize and discuss the latest clinical practice of KD for SRSE in critical care settings. Recommendations are given on patient selection, the timing of KD, diet implementation, and follow-up. More research data are needed in this area to support better clinical practice.

Abstract
Super-refractory status epilepticus (SRSE) is a life-threatening condition characterized by the persistence or recurrence of seizures despite the use of first- and second-line antiepileptic drugs and the continuous infusion of anesthetics for more than 24 hours. This has always been a challenge for the physician, given the high mortality and morbidity related to this condition. Unfortunately, there are currently no definitive data to guide the therapy, since most of the therapeutic approaches regarding SRSE come from anecdotal evidence. Here, we present a case report of long-persisting new-onset SRSE treated with unconventional therapies recently reported to be successful such as ketamine, ketogenic diet, and tocilizumab, that could have played an important role in the management of this patient. A review of the literature regarding those is also included. SRSE has been reported to have long hospital length of stay, with a small percentage of patients returning to baseline functional status. Moreover, recent evidence showed that functional and cognitive outcome could depend on seizure duration, so prolonged duration of epileptic activity with abnormalities on the magnetic resonance imaging (MRI) could be seen as a reason to discontinue treatment. However, despite many weeks of seizures and a noncomforting MRI, our patient was discharged with a good functional status.

Abstract
Ketogenic diet therapies are high-fat, low-carbohydrate diets designed to mimic a fasting state. Although initially developed nearly one century ago for seizure management, most clinical trials for the management of drug-resistant epilepsy in children as well as adults have been conducted over the last 3 decades. Moreover, ketogenic diets offer promising new adjunctive strategies in the critical care setting for the resolution of acute status epilepticus when traditional antiseizure drugs and anesthetic agents fail. Here, we review the history of ketogenic diet development, the clinical evidence supporting its use for the treatment of drug-resistant epilepsy in children and adults, and the early evidence supporting ketogenic diet feasibility, safety, and potential efficacy in the management of status epilepticus.

Abstract
Despite the rapid increase of clinical and basic-science knowledge on ketogenic diet therapies over the past years, it has not always been easy to determine the adequate indications of this treatment. Over the nearly 100 years of use, from being a last resource in the therapeutic algorithm, the diet has become one of the four main treatments for patients with difficult-to-control epilepsy together with antiepileptic drugs, surgery, and vagus nerve stimulation. The use of the diet has also changed. The current paper will briefly discuss the history of the diet together with a review of the literature regarding its most important indications and how they have evolved. The concept of the importance of defining the type of seizure, type of syndrome, and etiology in the selection of patients and timing of diet initiation has been gaining importance. This paper explores how the indications of the diet changed together with the shifting focus of epilepsy teams towards its use in different types of epilepsy and epilepsy syndromes and according to etiologies and as an alternative option in refractory and superrefractory status epilepticus.

Abstract
Status epilepticus (SE) is a medical emergency that is associated with a significant morbidity and mortality. Recently, there has been significant interest in the use of ketogenic diets (KD) in the management of SE. KD is a high‐fat, low‐carbohydrate, and adequate protein diet that has been shown to be a safe and effective adjuvant to present SE management in patients with refractory epilepsy. Many case reports and case series have demonstrated the potential safety and effectiveness of KD for the acute treatment of SE; however, quality studies remain scarce on this topic. The purpose of this systematic review is to summarize the available evidence for the safety and effectiveness of KD in adults with SE. A literature search was performed in MEDLINE, EMBASE, Cochrane Library, and CINAHL (September 14, 2018). The search was repeated on March 27, 2019, to include any studies published since the original search. Keywords related to KD and SE were used. Studies were selected based on the reported use of the KD in SE. The search resulted in a total of 954 records. After screening and full‐text review, 17 articles were included in this review: four observational studies, 10 case reports, and 3 case series. Based on the observational studies, a total of 38 Patients with SE have been reported. KD was successful in achieving cessation of SE in 31 Patients (82%). The most common adverse effects reported were metabolic acidosis, hyperlipidemia, and hypoglycemia. The current limited evidence suggests that KD might be considered as an option for adult patients with SE. Although promising, the results need to be interpreted with caution due to the inherent bias, confounding and small sample size of the included studies. A randomized controlled trial is recommended to establish role of KD in the management of SE in adults.

Abstract
OBJECTIVES Super-refractory status epilepticus (SRSE) is one of the most challenging issues in intensive care units (ICUs) in that it is associated with high morbidity and mortality. Although the ketogenic diet (KD) has been reported to be effective in treating of SRSE, the use of the diet as therapy can be complicated by concomitant medical problems specific to critically ill patients. In this study, we aimed to describe our experience of the KD for SRSE patients in ICUs. METHODS We retrospectively reviewed the medical records of 16 patients (10 males, 6 females) with SRSE who were treated with the KD in the ICUs at Samsung Medical Center from July 2005 to July 2017. RESULTS The median age of seizure onset was 8 years (interquartile range 5-13.5). Prior to diet initiation, the patients were in convulsive or non-convulsive SRSE for a median of 23 days (range, 3-420). The median time to achieve ketosis was 3 days (range, 2-6). The KD was continued for a median of 2.1 months (range, 0.1-15.8). Of the 16 patients, nine (56.3%) achieved seizure freedom, six (37.5%) reported >50% seizure reduction, and one (6.2%) had <50% seizure improvement after the KD. There was no significant change in the number of antiepileptic drugs. The most commonly encountered complication during the KD was gastrointestinal disturbance. CONCLUSIONS Our experience indicates that the KD is an effective alternative therapeutic strategy for SRSE patients in ICUs with adequate efficacy and safety in reducing seizure frequency and weaning from prolonged mechanical ventilation, although functional outcome was not favorable for most patients. Close monitoring and preventive management of potential adverse effects are critical elements for success with the KD in patients with SRSE.

Abstract
Nonconvulsive status epilepticus (NCSE) is present in multiple pediatric neurogenetic syndromes with epileptic encephalopathies. While intravenous (IV) medications are used inpatient for treatment of critical illness-related NCSE, there is no consensus on treatment of ambulatory NCSE. Up to 50% of patients with Angelman syndrome (AS) have NCSE with myoclonic or atypical absence status. Here we report our experience in pediatric patients with AS and NCSE treated outpatient with a tapering course of oral diazepam. We conducted a chart review of 104 patients seen in the Angelman Syndrome Clinic at Massachusetts General Hospital from January 2008 to March 2017, who met the criteria. Response to treatment was defined as cessation of NCSE symptoms with electroencephalogram (EEG) confirmation when possible. Twenty-one patients with NCSE were identified, and 13 patients (9 male) with 25 episodes of NCSE were included. Mean age at NCSE episode was 5years 4months (15months-12years). Six patients had one episode of NCSE, and 7 patients had recurrent episodes (mean: 2.7; range: 2-4). Median diazepam treatment was 6days (4-12days), with a mean dose of 0.32mg/kg/day divided over 2-3 administrations, decreased every 2days. Nine episodes required multiple courses; however, oral diazepam alone was ultimately successful in 80% (20/25) of NCSE episodes. Oral diazepam was well-tolerated with no major side effects. A short course of oral diazepam is well-tolerated and effective in patients with AS who have ambulatory NCSE. It may be considered prior to escalating to inpatient care in AS and possibly other epilepsy syndromes.

Abstract
A status epilepticus which persists for 24 hours or more after starting treatment with anaesthesia or has recurred inspite of general anaesthesia is known as Super-Refractory Status Epilepticus (SRSE). It includes cases where status epilepticus recurs on reduction or withdrawal of anaesthesia. SRSE, though infrequently seen, constitutes a medical emergency due to the associated high morbidity and mortality. No clear cut guidelines are available till date for the management of SRSE. Most of the published literature was case reports and expert opinion. We hereby reported three cases of super refractory seizures as they posed a therapeutic challenge. All three children were aged 6-7 years with prior normal developmental history and no medical illness. Viral meningoencephalitis, fever induced refractory status epilepticus, and auto-immune encephalitis was the probable aetiology in the cases studied. Midazolam, pentobarbital, and ketamine are the most commonly used anaesthetic agents. Phenytoin, phenobarbitone, valproate and levetiracetam are the most commonly used antiepileptic agents. All three cases had residual neurological deficits and morbidities like pneumonia and sepsis. SRSE is associated with high rates of mortality and morbidity necessitating immediate treatment.

Abstract
Super-refractory status epilepticus (SRSE) is a devastating neurological condition with limited treatment options. We conducted an extensive literature search to identify and summarize the therapeutic options for SRSE. The search mainly resulted in case reports of various pharmacologic and non-pharmacologic treatments. The success rate of each of the following agents, ketamine, inhaled anesthetics, intravenous immunoglobulin G (IVIG), IV steroids, ketogenic diet, hypothermia, electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), and vagal nerve stimulation (VNS), are discussed in greater detail. The choice of appropriate treatment options for a given patient is based on clinical presentation. This review focuses on evidence-based, pharmacotherapeutic strategies for patients in SRSE.

Abstract
Status epilepticus is a common pediatric neurological emergency. Management includes prompt administration of appropriately selected anti-seizure medications, identification and treatment of seizure precipitant(s), as well as identification and management of associated systemic complications. This review discusses the definitions, classification, epidemiology and management of status epilepticus and refractory status epilepticus in children.

Abstract
PURPOSE OF REVIEW To discuss the use of continuous infusions, general anesthesia, hypothermia, and ketogenic diet as treatment for uncontrolled status epilepticus in pediatric patients. RECENT FINDINGS Recent studies demonstrate that clinical practitioners have a hierarchy in approach in controlling refractory status epilepticus (RSE) and super-refractory status epilepticus in children. In the acute setting of RSE, midazolam achieves clinical seizure control at a mean of 41 min after starting an infusion. When midazolam has failed to control RSE, the evidence points to barbiturate anesthesia as the next frequently used option. When both midazolam and barbiturates have failed, use of isoflurane or ketamine anesthesia has been tried at a mean of 10 days after RSE onset, although the studies are largely anecdotal. Increasingly, the use of therapeutic hypothermia or ketogenic diet is described as a strategy for super-refractory status epilepticus, and better evidence for their use may become available from ongoing randomized studies. SUMMARY Uncontrolled episodes of status epilepticus require intensive care treatment and the literature describes a common pathway of care used by many. However, cases of truly refractory and super-refractory status epilepticus are seen infrequently at any given institution. One strategy to improve the quality of evidence is to develop prospective, national and multinational case registries to determine the range of presentations and causes, efficacy of treatments, and clinical outcomes.

Abstract
Febrile infection-related epilepsy syndrome (FIRES) is a newly recognized epileptic encephalopathy in which previously healthy school-aged children present with prolonged treatment-resistant status epilepticus (SE). Survivors are typically left with pharmacoresistant epilepsy and severe cognitive impairment. Various treatment regimens have been reported, all with limited success. The ketogenic diet (KD) is an alternative treatment of epilepsy and may be an appropriate choice for children with refractory SE. We report 2 previously healthy children who presented with FIRES and were placed on the KD during the acute phase of their illness. Both children experienced resolution of SE and were maintained on the KD, along with other anticonvulsant medications, for several months. Both were able to return to school, with some academic accommodations. These cases highlight the potential value of the KD as a preferred treatment in FIRES, not only in the acute setting but also for long-term management. Early KD treatment might optimize both seizure control and cognitive outcome after FIRES.

Abstract
The modified Atkins diet is a less restrictive variation of the ketogenic diet. This diet is started on an outpatient basis without a fast, allows unlimited protein and fat, and does not restrict calories or fluids. Recent studies have shown good efficacy and tolerability of this diet in refractory epilepsy. In this review, we discuss the use of the modified Atkins diet in refractory epilepsy.

Abstract
The modified Atkins diet has been used since 2003 for the treatment of children and adults with refractory epilepsy.This “alternative” ketogenic diet is started in clinic, without fasting, hospitalization, and restriction of protein,calories, or fluid intake. Now after 10 years of continued use, approximately 400 patients have been reported in over 30 studies of the modified Atkins diet as treatment for intractable seizures, with results demonstrating similar efficacy to the ketogenic diet and improved tolerability. The modified Atkins diet is being increasingly used in the adult population. Clinical trials have provided insight into the mechanisms of action of dietary therapies overall. This review will discuss the past decade of experience with the modified Atkins diet as well as predictions for its role in the treatment of epilepsy a decade from now.

Abstract
INTRODUCTION Refractory status epilepticus (RSE) in children is associated with a significant risk of death or neurological morbidity. Recently attention has been drawn to the ketogenic diet (KD) as an acute treatment, as it has shown promise in controlling seizures in otherwise refractory status epilepticus in several cases. We have listed these and reviewed all cases of KD used in RSE at our centre. KD was given as 4:1 fat:carbohydrate-protein solution. RESULTS A 3-year-old girl with RSE due to Hemiconvulsion-Hemiplegia Epilepsy syndrome. KD was instigated on day 6. Seizures stopped with ketosis on day 7. A 10-year-old boy rapidly developing RSE. After months a mitochondrial disorder was discovered. KD was tried twice with severe side-effects but no seizure control. 11-year-old healthy boy with RSE as FIRES. On KD seizures stopped for 24 h one day after reaching ketosis. He improved over 3-4 weeks. DISCUSSION KD was efficient in two of three cases of RSE. The non-responder had severe side-effects and proved to have a mitochondrial disorder which is arguably a contraindication for KD. More studies are needed to prove efficacy of KD in RSE, to define optimal timing of KD and possible contraindications for KD in RSE.

Abstract
PURPOSE Status epilepticus (SE) is a life-threatening condition that can be refractory to initial treatment. Randomized controlled studies to guide treatment choices, especially beyond first-line drugs, are not available. This report summarizes the evidence that guides the management of refractory convulsive SE (RCSE) in children, defines gaps in our clinical knowledge and describes the development and works of the 'pediatric Status Epilepticus Research Group' (pSERG). METHODS A literature review was performed to evaluate current gaps in the pediatric SE and RCSE literature. In person and online meetings helped to develop and expand the pSERG network. RESULTS The care of pediatric RCSE is largely based on extrapolations of limited evidence derived from adult literature and supplemented with case reports and case series in children. No comparative effectiveness trials have been performed in the pediatric population. Gaps in knowledge include risk factors for SE, biomarkers of SE and RCSE, second- and third-line treatment options, and long-term outcome. CONCLUSION The care of children with RCSE is based on limited evidence. In order to address these knowledge gaps, the multicenter pSERG was established to facilitate prospective collection, analysis, and sharing of de-identified data and biological specimens from children with RCSE. These data will allow identification of treatment strategies associated with better outcomes and delineate evidence-based interventions to improve the care of children with SE.

Abstract
One of the newest and yet fastest growing indications for dietary therapy is the emergency treatment of refractory status epilepticus. Ten retrospective publications since 2008 have reported benefits in 32 children and adults, of whom 25 (78%) became seizure-free. Most of the patients who responded did so within 7 to 10 days of the initiation of nasogastrically administered ketogenic formulas. Encephalitis and febrile-illness related epilepsy syndrome causing status epilepticus highly refractory to antiepileptic drugs may be particularly amenable to dietary treatment. Prospective, multicenter studies are under way to help clarify who best will respond, how quickly, and the optimal diet duration after success.

Abstract
The modified Atkins diet has been studied in mostly short-term clinical trials and case series. No studies have systematically examined the long-term benefits and side effects. The modified Atkins diet was started without prior ketogenic diet use in 87 children at the Johns Hopkins Hospital since 2002, of which 54 continued for more than 6 months. Children who had not been seen within the past 2 years were contacted by phone and email. At their most recent point during the modified Atkins diet (mean 19.9 months), 30 of 54 (55%) children with diet durations of more than 6 months achieved >50% improvement; 19 (35%) were seizure-free. Using an intent-to-treat analysis, at 12 months, 33 of 87 (38%) had >50% seizure reduction; 16 (18%) were seizure-free. These results are similar to published data for short-term modified Atkins diet and long-term ketogenic diet use. Side effects were predominantly elevations in lipid profile and gastrointestinal upset.

Abstract
The modified Atkins diet (MAD) consists of a nearly balanced diet without any age-dependent restriction of recommended daily calorie intake. Recently, there has been a marked increase in the use of the MAD in the treatment of epilepsy. Over the last 8 years, evidence suggesting that the MAD may exhibit similar anticonvulsant properties as the traditional ketogenic diet (KD) has been accumulating. KD is now an 'evidence-based' treatment for refractory epilepsy. Although there are currently no direct comparisons data from the literature suggest that the KD is more efficacious than the MAD. However, the MAD is easier to administer and has better tolerability. This review discusses when to consider each diet. The MAD may be the first diet of choice. In case of insufficient efficacy under the MAD, a switch from the MAD to the KD should be considered.

Abstract
Ten Japanese patients aged 1.5-17years with medication-resistant epilepsy were placed on the modified Atkins diet (MAD) for 3weeks during admission to our hospital. Dietary carbohydrate was restricted to 10g per day. We studied the efficacy of the diet regarding the seizure frequency and tolerability of the diet at the end of the 3weeks on the diet. Those who decided to continue the MAD at the time of discharge were followed up in the out-patient clinic to observe the effect of the diet on the seizure frequency. Three of the 10 patients could not continue the diet during the 3-week admission; one had rotavirus enterocolitis and the other 2 disliked the diet. Among the remaining 7 patients who could continue the diet for 3weeks, 3 achieved the seizure reduction; 2 became seizure-free and 1 showed about 75% reduction in the seizure frequency within 10days on the diet. All of these 3 patients continued the diet after the 3-week admission. The other 4 patients did not show a reduction of the seizure frequency by the end of the 3weeks on the diet. Two of them discontinued the diet on discharge. The remaining 2 still continued the diet at home and one became seizure-free 3months after the start of the diet. In total, 4 of 10 patients achieved>75% reduction in the seizure frequency, although relapse occurred in 2 of the patients, at 5months and 2years after seizure reduction, respectively. The MAD was effective and well-tolerated in children with medication-resistant epilepsy in Japan.

Abstract
The modified Atkins diet is a high-fat, low-carbohydrate treatment for intractable childhood epilepsy. As data suggest that a stricter diet onset can be more effective, we added a ketogenic supplement to the modified Atkins diet during its initial month. Thirty children with intractable epilepsy were prospectively started on the modified Atkins diet in combination with a daily 400-calorie KetoCal shake. At 1 month, 24 (80%) children had >50% seizure reduction, of which 11 (37%) had >90% seizure reduction. There was no significant loss of efficacy during the second month after KetoCal was discontinued. The use of this ketogenic supplement increased daily fat intake and thus the ketogenic ratio (1.8:1 versus 1.0:1 in the modified Atkins diet alone, P = .0002), but did not change urinary or serum ketosis. The addition of a ketogenic supplement to the modified Atkins diet during its initial month appears to be beneficial.

Abstract
Modified Atkins diet (MAD) is a less restrictive variety of the classical ketogenic diet (KD), used for treating patients with medically resistant epilepsy. There are only few reports comparing the two types of diets in terms of seizure reduction and tolerability. We compared the effect of a MAD evaluated prospectively on 33 consecutive children with medically resistant epilepsy, with a group of 50 patients, previously treated with KD. Patients who had >50% seizure reduction were considered responders. After 3 months on the MAD, 17 patients (52%) were responders, including 14 (42%) who had >90% seizure reduction. After 6 months, 13 patients (39%) were responders. Seventeen patients (52%) remained on the MAD at least 12 months with excellent overall tolerance and compliance, including 9 patients (27%) who were responders, 4 of them (12%) having >90% seizure reduction. Although there was a trend for higher incidence of responders in the KD group, this failed to reach the level of significance: after 6 months 39% on MAD and 60% on KD were responders. However, this trend was not observed when the two groups were adjusted for difference in age (patients in the MAD group were older than the KD group). In conclusion, our experience suggests that the MAD is similarly effective as the KD in reducing seizure frequency in children with medically resistant epilepsy.

Abstract
Refractory convulsive status epilepticus occurs when seizures are not controlled with initial benzodiazepine therapy or a subsequent anticonvulsant drug. Typically drug-induced anesthesia is then pursued with midazolam or a barbiturate. This results in prolonged, intensive care, which requires meticulous attention to medical management to minimize complications. When seizures persist other options must be considered. These include (1) other medications, (2) surgery, (3) the ketogenic diet, (4) hypothermia, (5) inhalational anesthetic agents, and (6) immune modulating therapy. This review addresses the literature related to the use of the latter (4) treatment options. I will discuss the role of each treatment and review the evidence for it's use, along with possible side-effects.
