Caregiver burden in epilepsy: determinants and impact.
Aim. Caregiver burden (CB) in epilepsy constitutes an understudied area. Here we attempt to identify the magnitude of this burden, the factors associated with it, and its impact to caregiver quality of life (QOL). Methods. 48 persons with epilepsy (PWE) underwent video-EEG monitoring and their caregivers completed questionnaires providing demographic, disease-related, psychiatric, cognitive, sleep, QOL, and burden information. Results. On regression analysis, higher number of antiepileptic drugs, poorer patient neuropsychological performance, lower patient QOL score, and lower caregiver education level were associated with higher CB. Time allocated to patient care approximated but did not attain statistical significance. A moderate inverse correlation between CB and caregiver QOL physical component summary score and a stronger inverse correlation between CB and caregiver QOL mental component summary score were seen. Conclusion. In a selected cohort of PWE undergoing video-EEG monitoring, we identified modest degree of CB, comparable to that reported in the literature for other chronic neurological conditions. It is associated with specific patient and caregiver characteristics and has a negative effect on caregiver QOL

Challenges in identifying Lennox–Gastaut syndrome in adults: A case series illustrating its changing nature
The variable presentation and progression of Lennox–Gastaut syndrome (LGS) can make it difficult to recognize, particularly in adults. To improve diagnosis, a retrospective chart review was conducted on patients who were diagnosed as adults and/or were followed for several years after diagnosis. We present 5 cases that illustrate changes in LGS features over time. Cases 1 and 2 were diagnosed by age 8 with intractable seizures, developmental delay, and abnormal EEGs with 1.5–2 Hz SSW discharges. However, seizure type and frequency changed over time for both patients, and the incidence of SSW discharges decreased. Cases 3, 4, and 5 were diagnosed with LGS as adults based on current and past features and symptoms, including treatment-resistant seizures, cognitive and motor impairment, and abnormal EEG findings. While incomplete, their records indicate that an earlier LGS diagnosis may have been missed or lost to history. These cases demonstrate the need to thoroughly and continuously evaluate all aspects of a patient's encephalopathy, bearing in mind the potential for LGS features to change over time

A Quick and Reliable EEG Montage for the Detection of Seizures in the Critical Care Setting
Obtaining an emergent EEG for the diagnosis of nonconvulsive status epilepticus and conconvulsive seizures in the intensive care unit raises logistic problems in most hospitals. Previous studies have looked into the hairline EEG for a broader population than the critically ill, with controversial conclusions. The authors created a montage sufficiently simple to be performed and interpreted by residents and rapidly achievable to meet the time constraints of a busy on-call schedule. Seven electrodes (Fp1, Fp2, T3, T4, O1, O2, and Cz), easily applied without the need for tape measure by using only anatomic landmarks (pupils, ears, vertex, and inion), were used to configure three different montages: double diamond, circumferential, and Cz referential. EEG records obtained with the full 10-20 system in critically ill patients were reformatted into these montages and reviewed retrospectively independently by neurology attending physicians with expertise in EEG interpretation and senior neurology residents. A comparison was done with the previously studied hairline EEG. The average sensitivity of the study montage for seizure detection was 92.5%, whereas the average specificity was 93.5%. These results suggest that the seven-electrode montage could potentially be a quick and reliable EEG montage for the detection of seizures in the intensive care unit, when technical support is not available. Further prospective studies are required to validate these promising results in a larger population sample
Conversions between monotherapies in epilepsy: expert consensus.
To develop expert consensus for conversion between antiepileptic drug (AED) monotherapies, an 11-member panel used the Delphi Technique over three rounds to: (1) identify relevant issues, (2) vote on the issues, and (3) develop consensus. The panel agreed on the basic principle to taper the existing AED only after a presumably efficacious dose of the planned AED was reached. Application is modified by adverse effects possibly attributable to the existing drug, in which case earlier or more rapid tapering of the existing drug should be considered. Patients with uncontrolled seizures, as well as seizure-free patients for whom driving privileges are a consideration, may benefit from slower tapering by smaller dosage decrements of the existing AED. For 10 of the 12 AEDs considered, the panel made titration recommendations concerning initial and target doses for the planned AED, supplementing limited data in the prescribing information. This expert guidance will aid in the period of transitional polytherapy with AEDs from monotherapy to monotherapy

Efficacy and Tolerability of the New Antiepileptic Drugs, I: Treatment of New-Onset Epilepsy: Report of the TTA and QSS Subcommittees of the American Academy of Neurology and the American Epilepsy Society
Purpose: To assess the evidence demonstrating efficacy, tolerability, and safety of seven new antiepileptic drugs [AEDs; gabapentin (GBP), lamotrigine (LTG), topiramate (TPM), tiagabine (TGB), oxcarbazepine (OXC), levetiracetam (LEV), and zonisamide (ZNS), reviewed in the order in which these agents received approval by the U.S. Food and Drug Administration] in the treatment of children and adults with newly diagnosed partial and generalized epilepsies. Methods: A 23-member committee, including general neurologists, pediatric neurologists, epileptologists, and doctors in pharmacy, evaluated the available evidence based on a structured literature review including MEDLINE, Current Contents , and Cochrane Library for relevant articles from 1987 until September 2002, with selected manual searches up to 2003. Results: Evidence exists, either from comparative or dose-controlled trials, that GBP, LTG, TPM, and OXC have efficacy as monotherapy in newly diagnosed adolescents and adults with either partial or mixed seizure disorders. Evidence also shows that LTG is effective for newly diagnosed absence seizures in children. Evidence for effectiveness of the new AEDs in newly diagnosed patients with other generalized epilepsy syndromes is lacking. Conclusions: The results of this evidence-based assessment provide guidelines for the prescription of AEDs for patients with newly diagnosed epilepsy and identify those seizure types and syndromes for which more evidence is necessary.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65231/1/j.0013-9580.2004.06204.x.pd
