Clinical, Journal: Randomized Trial of Three Anticonvulsant Medications for Status Epilepticus. (Pubmed Central) - Dec 19, 2019 P3 In the context of benzodiazepine-refractory convulsive status epilepticus, the anticonvulsant drugs levetiracetam, fosphenytoin, and valproate each led to seizure cessation and improved alertness by 60 minutes in approximately half the patients, and the three drugs were associated with similar incidences of adverse events. (Funded by the National Institute of Neurological Disorders and Stroke; ESETT ClinicalTrials.gov number, NCT01960075.).

Preclinical, Journal: Characterization of Epileptic Spiking Associated With Brain Amyloidosis in APP/PS1 Mice. (Pubmed Central) - Dec 1, 2019 These data show that by only adding a pair of hippocampal deep electrodes and EMG to routine cortical epidural screw electrodes and by taking into account underlying cortical oscillations, one can drastically refine the analysis of cortical spike data. This new approach provides a powerful tool to preclinical testing of potential new treatment options for AD related epilepsy.

Journal: Images: Facial cataplexy with demonstration of persistent eye movements. (Pubmed Central) - Nov 29, 2019 The diagnosis of cataplexy is often missed, due to clinicians being unfamiliar with the findings and the lack of ability to induce sufficient emotional responses to trigger an episode. This example of cataplexy is also quite characteristic of the "cataplectic facies." The ability to observe the infrequently observed phenomenon of cataplexy serves as a reminder that consciousness is preserved, as are extra-ocular muscle movements.

Brivaracetam Is More Effective Than Levetiracetam in the Treatment of Experimental Benzodiazepine-Refractory Status Epilepticus (Hall E) - Nov 28, 2019 - Abstract #AES2019AES_1551; Studies of acute neuronal injury showed strong neuroprotection in all groups treated with ketamine. Conclustions This experiment demonstrates that brivaracetam in more effective than higher-dose levetiracetam in stopping seizures in this model of RSE, and confirms that combinations of a GABAA receptor allosteric stimulator, a NMDA receptor antagonist and an antiepileptic drug are superior to monotherapy in treating RSE.

Multinodular and Vacuolating Neuronal Tumors of the Temporal Lobe (Hall E) - Nov 28, 2019 - Abstract #AES2019AES_1516; She has rare breakthrough seizures on zonisamide...Also, it is unclear whether lesionectomy is sufficient, or if these patients require 2-step epilepsy surgery with invasive monitoring to define epileptic zone margins beyond radiographic margins. Larger multi-center case series would help to answer these questions.

Awareness of Seizures: Patient Report and RNS Record (Hall E) - Nov 28, 2019 - Abstract #AES2019AES_1515; It can also be challenging to differentiate focal seizures without awareness from non-epileptic hypervigilant behaviors by patients’ descriptions. RNS ECog recordings provide further objective electrophysiological evidence, and therefore could be helpful in the diagnosis and treatment.

Use of Brivaracetam in Cases of Acquired Pathologic Myoclonus (Hall E) - Nov 28, 2019 - Abstract #AES2019AES_1512; This may suggest the potential of an additive benefit in spite of a similar mechanism of action between levetiracetam and brivaracetam. It is unclear if this effect would be similar in the absence of levetiracetam.

Intranasal midazolam and intravenous lorazepam were specified as first line benzodiazepines (BZD), second line medication options were expanded (see Figure 1), and midazolam was recommended as the initial third line continuous infusion...Considering all second line medications given (with and without SE), more valproic acid (p=0.0001) and less levetiracetam (p=0.008) were provided post-pathway, but this was not associated with reduced frequency of fosphenytoin and phenobarbital dosing (p=0.957)...While different second line medications were prescribed post-pathway, the overall incidence of requiring one and two doses of second-line medication was unchanged. Further analyses will evaluate whether these changes were associated with changes in patient outcome.

Evaluation of the Acute Anticonvulsant Efficacy of Fenfluramine in Mouse Models of Acute and Chronic Seizures (Hall E) - Nov 28, 2019 - Abstract #AES2019AES_1387; Conclustions Acute administration of FFA exerted dose-dependent anticonvulsant effect in the mouse MES test, a model of tonic-clonic seizures in humans, an observation aligning with the clinical experience with FFA in Dravet syndrome. FFA may also have activity against focal seizures that secondarily generalize, but effects in different models were inconsistent, suggesting that further studies are warranted.

Utility of Inpatient Brain MRI and EEG for New-Onset Seizures: A Five-Year Single Hospital Experience (Hall E) - Nov 28, 2019 - Abstract #AES2019AES_1361; Conclustions At our institution, patients presenting with new-onset seizure and a normal neurologic exam typically have additional testing such as MRI brain and EEG as an outpatient, whereas those who present with an abnormal neurologic exam often have these tests done on an inpatient basis. This retrospective chart review of the utility of such testing in the inpatient setting supports the continued practice of obtaining these tests when deemed necessary by a neurologist as they frequently led to a change in acute management or an anticipated change in future outpatient management.

Those who had a shorter latency to their outpatient visits had a significantly lower average number of seizures which underlines the importance of continued care after the resolution of status epilepticus.

Medical provider and patient education is essential in planning pregnancies and prescribing folic acid as AA WWE may be exposed to slightly higher risks of complications in pregnancy than reported in existing national registries.

Given that the safety profile of 25 mg/kg/d was superior to 50 mg/kg/d, the lower dose range confers a superior benefit to risk ratio.
