Lamotrigine add-on therapy for drug-resistant focal epilepsy.

Background: This is an updated version of the Cochrane Review previously published in 2016. Epilepsy is a common neurological disorder, affecting 0.5% to 1% of the population.

Pregabalin add-on for drug-resistant focal epilepsy.

Background: Epilepsy is a common neurological disease that affects approximately 1% of the UK population. Approximately one-third of these people continue to have seizures despite drug treatment. Pregabalin is one of the newer antiepileptic drugs which have been developed to improve outcomes.

A pilot study on the efficacy of transcranial direct current stimulation applied to the pharyngeal motor cortex for dysphagia associated with brainstem involvement in multiple sclerosis.

Objective: we investigated the effect of anodal transcranial direct current stimulation (tDCS) applied over the pharyngeal motor area in dysphagia associated with multiple sclerosis (MS).

Methods: Eighteen MS patients with dysphagia associated with brainstem involvement were randomized to receive either "real" or "sham" tDCS.

Primary Outcome: The Penetration/Aspiration Scale (PAS).

Gabapentin add-on treatment for drug-resistant focal epilepsy.

Background: This is an updated version of the Cochrane Review previously published in 2013.Most people with epilepsy have a good prognosis and their seizures are well controlled by a single antiepileptic drug, but up to 30% develop drug-resistant epilepsy, especially those with focal seizures. In this review, we summarised the evidence from randomised controlled trials (RCTs) of gabapentin, when used as an add-on treatment for drug-resistant focal epilepsy.

Rufinamide add-on therapy for refractory epilepsy.

Background: Epilepsy is a central nervous system disorder (neurological disorder). Epileptic seizures are the result of excessive and abnormal cortical nerve cell electrical activity in the brain. Despite the development of more than 10 new antiepileptic drugs (AEDs) since the early 2000s, approximately a third of people with epilepsy remain resistant to pharmacotherapy, often requiring treatment with a combination of AEDs.

Yoga for epilepsy.

Background: This is an updated version of the original Cochrane Review published in the Cochrane Library, Issue 5, 2015.Yoga may induce relaxation and stress reduction, and influence the electroencephalogram and the autonomic nervous system, thereby controlling seizures. Yoga would be an attractive therapeutic option for epilepsy if proved effective.

Carbamazepine versus phenytoin monotherapy for epilepsy: an individual participant data review.

Background: This is an updated version of the original Cochrane Review published in Issue 2, 2002 and its subsequent updates in 2010 and 2015.Epilepsy is a common neurological condition in which recurrent, unprovoked seizures are caused by abnormal electrical discharges from the brain. It is believed that with effective drug treatment, up to 70% of individuals with active epilepsy have the potential to become seizure-free and go into long-term remission shortly after starting drug therapy with a single antiepileptic drug in monotherapy.

Carbamazepine versus phenobarbitone monotherapy for epilepsy: an individual participant data review.

Background: This is an updated version of the original Cochrane Review, first published in Issue 1, 2003 and updated in 2015. This review is one in a series of Cochrane Reviews investigating pair-wise monotherapy comparisons.Epilepsy is a common neurological condition in which abnormal electrical discharges from the brain cause recurrent unprovoked seizures.

Immediate-release versus controlled-release carbamazepine in the treatment of epilepsy.

Background: Carbamazepine (CBZ) is a commonly used drug for epilepsy that is associated with troublesome adverse events including dizziness, double vision, drowsiness, poor co-ordination and unsteadiness. These adverse events often occur during peaks in drug plasma concentration. These adverse events may limit the daily dose of CBZ that can be tolerated and reduce the chances of seizure control in patients who require high doses.

Topiramate versus carbamazepine monotherapy for epilepsy: an individual participant data review.

Background: Epilepsy is a common neurological condition in which abnormal electrical discharges from the brain cause recurrent unprovoked seizures. It is believed that with effective drug treatment, up to 70% of individuals with active epilepsy have the potential to become seizure-free and go into long-term remission shortly after starting drug therapy, the majority of which may be able to achieve remission with a single antiepileptic drug (AED).The correct choice of first-line antiepileptic therapy for individuals with newly diagnosed seizures is of great importance.

Monotherapy treatment of epilepsy in pregnancy: congenital malformation outcomes in the child.

Background: There is evidence that certain antiepileptic drugs (AEDs) are teratogenic and are associated with an increased risk of congenital malformation. The majority of women with epilepsy continue taking AEDs throughout pregnancy; therefore it is important that comprehensive information on the potential risks associated with AED treatment is available.

Objectives: To assess the effects of prenatal exposure to AEDs on the prevalence of congenital malformations in the child.

Vagus nerve stimulation therapy in partial epilepsy: a review.

Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked epileptic seizures. The majority of people given a diagnosis of epilepsy have a good prognosis, but 20-30 % will develop drug-resistant epilepsy. Vagus nerve stimulation (VNS) is a neuromodulatory treatment that is used as an adjunctive therapy for treating people with medically refractory epilepsy.

Non-pharmacological interventions for people with epilepsy and intellectual disabilities.

Background: Approximately 30% of patients with epilepsy remain refractory to drug treatment and continue to experience seizures whilst taking one or more antiepileptic drugs (AEDs). Several non-pharmacological interventions that may be used in conjunction with or as an alternative to AEDs are available for refractory patients. In view of the fact that seizures in people with intellectual disabilities are often complex and refractory to pharmacological interventions, it is evident that good quality randomised controlled trials (RCTs) are needed to assess the efficacy of alternatives or adjuncts to pharmacological interventions.

Pharmacological interventions for epilepsy in people with intellectual disabilities.

Background: The prevalence of epilepsy among people with intellectual disabilities is much higher than in the general population. Seizures in this population are often complex and refractory to treatment and antiepileptic medication may have a profound effect upon behaviour (Kerr 1997).This is an updated version of a Cochrane Review first published in Issue 3, 2007.

Neuropsychological and psychological interventions for people with newly diagnosed epilepsy.

Background: Many people with epilepsy report experiencing psychological difficulties such as anxiety, depression and neuropsychological deficits including memory problems. Research has shown that these difficulties are often present not only for people with chronic epilepsy but also for people with newly diagnosed epilepsy. Despite this, there are very few published interventions that detail means to help people with newly diagnosed epilepsy manage these problems.

Assessment of the quality of harms reporting in non-randomised studies and randomised controlled studies of topiramate for the treatment of epilepsy using CONSORT criteria.

Purpose: Treatment decisions should be informed by high quality evidence of both the potential benefit and harms of treatment alternatives. Randomised controlled trials (RCTs) provide the best evidence regarding benefits; however information relating to serious, rare and long-term harms is usually available only from non-randomised studies (NRSs). The aim of this study was to use a checklist based on the CONSORT (Consolidating Standards for Reporting Trials) extension for harms recommendations to assess the quality of reporting of harms data in both NRSs and RCTs of antiepileptic drugs, using studies of topiramate as an example.

Lacosamide add-on therapy for partial epilepsy.

Background: Around half of people with epilepsy will not achieve seizure freedom on their first antiepileptic drug; many will require add-on treatment with another drug. Sometimes multiple treatment combinations are tried to achieve maximum seizure control, although around a third of people do not achieve complete seizure control. Lacosamide is an antiepileptic drug that has been licensed as an add-on treatment for partial epilepsy.

Yoga for epilepsy.

Background: This is an updated version of the original Cochrane review published in The Cochrane Library, Issue 1, 2002.Yoga may induce relaxation and stress reduction, and influence the electroencephalogram and the autonomic nervous system, thereby controlling seizures. Yoga would be an attractive therapeutic option for epilepsy if proved effective.

Vagus nerve stimulation for partial seizures.

Background: Vagus nerve stimulation (VNS) is a neuromodulatory treatment that is used as an adjunctive therapy for treating people with medically refractory epilepsy. VNS consists of chronic intermittent electrical stimulation of the vagus nerve, delivered by a programmable pulse generator. The majority of people given a diagnosis of epilepsy have a good prognosis, and their seizures will be controlled by treatment with a single antiepileptic drug (AED), but up to 20%-30% of patients will develop drug-resistant epilepsy, often requiring treatment with combinations of AEDs.

Antiepileptic drugs as prophylaxis for post-craniotomy seizures.

Background: The incidence of seizures following supratentorial craniotomy for non-traumatic pathology has been estimated to be between 15% to 20%; however, the risk of experiencing a seizure may vary from 3% to 92% over a five-year period. Postoperative seizures can precipitate the development of epilepsy; seizures are most likely to occur within the first month of cranial surgery. The use of antiepileptic drugs (AEDs) administered pre- or postoperatively to prevent seizures following cranial surgery has been investigated in a number of randomised controlled trials (RCTs).

Pregabalin add-on for drug-resistant partial epilepsy.

Background: Epilepsy is a common chronic neurological disease with an estimated prevalence of 1% in the UK. Approximately one third of these people continue to have seizures despite drug treatment. In order to try to improve outcomes a number of new antiepileptic drugs have been developed and pregabalin is one of these.

Topiramate add-on for drug-resistant partial epilepsy.

Background: The majority of people with epilepsy have a good prognosis and their seizures are controlled by a single antiepileptic drug. However, up to 20% of patients from population-based studies and up to 30% from clinical series (not population-based) develop drug-resistant epilepsy, especially those with partial onset seizures. In this review we summarise the current evidence regarding topiramate, an antiepileptic drug first marketed in 1996, when used as an add-on treatment for drug-resistant partial epilepsy.

Tiagabine add-on for drug-resistant partial epilepsy.

Background: Epilepsy is a common neurological condition that affects almost 0.5% to 1% of the population. Nearly 30% of people with epilepsy are resistant to currently available drugs.

Zonisamide add-on for drug-resistant partial epilepsy.

Background: The majority of people with epilepsy have a good prognosis and their seizures can be well controlled with the use of a single antiepileptic agent, but up to 30% develop refractory epilepsy, especially those with partial seizures. In this review we summarise the current evidence regarding zonisamide, when used as an add-on treatment for drug-resistant partial epilepsy.

Objectives: To evaluate the efficacy and tolerability of zonisamide when used as an add-on treatment for people with drug-resistant partial epilepsy.
