Biography:

Jeffrey M. Chung received his Doctor in Medicine from Northwestern University Medical School. He is currently the Director of Epilepsy and Neurophysiology Programs at Cedars-Sinai Medical Center and an Associate Clinical Professor of Neurology at UCLA. He has presented at multiple national and international conferences on the localization of the epileptogenic zone with neuronal signal processing analysis and on the prediction of surgical decisions and outcomes with multi-modal probabilistic mapping techniques. His awards include Falks Medical Scholar, CARE Outstanding Patient Care Award, and the Clinical Research Fellowship Training Award from the Epilepsy Foundation, and multiple teaching awards.

Abstract:

High frequency oscillations (HFO)—100 – 150 Hz—are thought to be the earliest ictal onset frequencies which may be used to identify the epileptogenic zone for surgical resection. We analyzed EEG data sampled at 2 khz from 10 patients with medically refractory partial epilepsy undergoing intracranial macroelectrode monitoring (5 depth electrodes, 5 subdural grids).Multiband frequency and power analysis were performed to characterize the predominating frequency during the interictal, pre-ictal, ictal, and postictal periods. Thirty-seven seizures—17 from subdural grid and 20 from depth electrodes—were analyzed. In eight patients, power spectrogram between 0 – 100 Hz demonstrated the ictal onset was localized to one contact and was characterized by a significant increase of 10 – 30 Hz frequencies preceding the increase of 30 – 100 Hz frequencies by 3 seconds before propagation. Focal surgical resections were performed in the areas correlated to the synchronization of these alpha-beta frequencies and HFO prior to and during the patients’ clinical seizures. These eight patients have seizure-free outcomes confirming the localization. In contrast, the alpha-beta frequencies synchronization was not seen in two patients (13 seizures) who did not become seizure-free. Previous studies of HFO from intracranial EEG recordings consistently show the frequencies at ictal onset above gamma range. In contrast, we found that HFO were preceded by lower frequencies, and the presence of the lower frequency synchronization correlated with post-operative seizure freedom. HFO may not be the first ictal manifestation in some cases and lower frequency ictal frequencies should not be overlooked. Larger studies are underway.

Abstract:

Epilepsy is a complex disorder, noted for its heterogeneous and unpredictable manifestation which can amplify diagnostic uncertainty.   This can be exacerbated by variability in access to diagnostic methods and site personnel experience with various epileptic syndromes.  Even when the clinical diagnosis is accurate, seizure frequency is notoriously difficult to measure reliably and even more problematic to assess in pediatric epilepsy trials. These concerns are intensified when trials are performed on a global scale and across numerous study centers that conduct neurological clinical trials in multiple indications.

I will discuss how Syneos Health can help minimize the risk of these issues through the use of our Clinical Surveillance and Training (CST) team.  In addition, Syneos Health can offer additional value propositions regarding the next stage in clinical development – commercialization.  Research indicates that 75% of products across various indications that reach the market are commercial failures because they lack integrated planning across the clinical and commerical continuum. 

At Syneos Health-the industry’s only biopharma accelerator, we understand the worldwide gold standard for solving intricate problems and optimizing opportunities, thereby ensuring that promising compounds have the important support in order to make it to market.  Clinical Surveillance & Training has over twenty years of experience working in clinical trials and works to streamline efficiencies to address data impacting errors discovered during seizure diary review processes, thereby helping to increase the likelihood of commercial success in Epilepsy Trials

Abstract:

Super refractory status Epilepticus is an uncommon, but very important clinical problem that is associated with high morbidity and mortality. Studies concerning Super refractory status epilepticus has been limited. Up to present, there are no existing Philippine data. The study aims to determine the status of Refractory and Super refractory status epilepticus within a 10-year period in a Tertiary Hospital. This is a retrospective study of adult patients with prolonged seizures admitted at a Tertiary Hospital from January 2009- July 2018.  Frequency, Mean and standard deviation was used in the Descriptive analysis. Multinomial Logistic Regression was used to assess probability of good or poor outcome. Significant Correlation is defined by P value of <0.05. The Incidence of Refractory Status Epilepticus is as high as 38% (n=64) and 35% (n=58) for Super Refractory Status Epilepticus. Mortality rate is 39.1% in Refractory and 62.1% in Super refractory status epilepticus. Poor functional outcome has been observed in RSE and SRSE whein the majority was Alive Dependent. Significant factor increasing likelihood of being Alive Dependent is the absence of Arrest. Factors associated with likelihood of being alive and independent includes Status Epilepticus which is more benign type of prolonged seizure and younger age therefore more aggressive control of seizures in preventing progression to SRSE will give higher likelihood of good functional outcome and elderly patients would need closer and more adept seizure control for better functional outcome.

Abstract:

The Milk Awareness Campaign, eight rules to respect in case of a seizure With half a million people living with Epilepsy, and 30,000 new cases found per year in Italy, this disease has become a very common pathology and a one worth of attention. This is why Aice (Italian Association Against Epilepsy Veneto), Lice (Italian League Against Epilepsy), and Lattebusche, joined forces to ease how to deal with an epileptic seizure, by printing on 300,000 Lateebusche cartons of milk the 8 rules to follow in case of a seizure. This awareness campaign aims at reaching at least 1.5 million people if not more. The campaign builds on the last national conference held in Padua, "Update in Epileptology", and aims at raising awareness, educate the population and patients, and break down false myths on this pathology.

Abstract:

Background: The Neurocutaneous Syndromes (N.S.) are a rarther heterogeneous group of diseases from both a clinical and genetic point of view. Most N.S. reveal themselves through convulsive crises, wich sometimes do not respond to the pharmacological treatment. The purpose of this study is to evaluate the therapeutic and clinical aspects of and adequate therapeutic procedure.

Methods: 78 children have been studied, they are affected by: 33 children from neurofibromatosis; 23 children from tuberous sclerosis; 9 children from the Sturge-weber syndrome; 5 from Ito hypomelanosis; 4 from incontinentia pigmenti: | from Dubowitz syndrome; | from the Schimmelpenning-Feuerstin-mims syndrome;! from kippel-Trenaunay-weber syndrome, 1 from ataxia-telangiectasia. The anamnesis, the hystory of the cris and of the anti-epileptic therapy was recorder for each case.

Results: The initial critical symptomatology was divided into groups: infantile spasms; simple focal seizures; focal focal epilepsy; generalized crises. The age of onset at the beginning of the critical symptomatology is between 15 days and 5 years of age. The neuroradiological pictures observed with brain MRI are fairly heterogeneous. The evolution and the current state of epileptic symptoms has been evaluated: 40% of cases have generalized epilepsy: 60% of cases a focal epilepsy. The most used drugs are: VPA, CBZ, PB, LTG, BDZ. In some cases cycles of cortisone therapy (cases with infantile spasms, S. di Lennox-Gastaut) were also practiced. Conclusions: The neurocutaneous syndromes constitute a group of quite heterogeneous pathologies. The use of tools such as TAC and, above all, MRI are essential for a correct diagnostic classification. EEG changes are clearly correlated with the type and extent of the malformation pattern; it seems difficult to establish a specific and pathognomonic picture of a form of S.N. It remains however difficult to establish, in these pathologies, what is the evolution, the therapeutic strategy to be implemented and the prognosis of the epileptic symptomatology based on its time of onset and the associated neuroradiological framework. It is therefore important to underline how the use of new pharmacological therapies leads to a considerable reduction of critical episodes and consequentially to an improvement in the life of these subjects.

Abstract:

Microglia are the principle immune cells in the central nervous system. They are highly dynamic and interact constantly with neurons. During neuronal hyperactivities under seizure conditions, we found an unique microglia-neuron interaction we named “microglial process extension”, that is, an increased number of microglial primary processes toward hippocampal neurons. The mechanism of microglial process extension involves the activation of neuronal NMDA receptors, calcium influx, subsequent ATP release, and microglial response through P2Y12 receptors. The interaction is potentially neuroprotective because P2Y12 knockout mice exhibited reduced seizure-induced increases in microglial process numbers and worsened KA-induced seizure behaviors. Our recent studies further found that activated hippocampal microglia highly expressed chemokine CCL2 in kainic acid (KA)-induced seizure mice. Taking advantage of CX3CR1GFP/+:CCR2RFP/+ double-transgenic mice, we demonstrated that CCL2-CCR2 signaling plays a critical role in blood-derived monocyte infiltration. Moreover, seizure-induced degeneration of neurons in the hippocampal CA3 region was attenuated in mice lacking CCL2 or CCR2. We further showed that CCR2 activation induced STAT3 (signal transducer and activator of transcription 3) phosphorylation and IL-1β production, which are critical for promoting neuronal cell death after status epilepticus. Two weeks after KA-induced seizures, CCR2 deficiency not only reduced neuronal loss, but also attenuated seizure-induced behavioral impairments, including anxiety, memory decline, and recurrent seizure severity. Together, we demonstrated that resident microglia have the neuroprotective potential while infiltrated monocytes contribute mostly to neuroinflammation that is neurotoxic in epilepsy.

Abstract:

Background: Epileptic seizures are resistant to pharmacotherapy in approximately 1/3 of all instances, a statistic that has not changed despite the introduction of >20 new antiepileptic drugs in the late twentieth and early twenty-first century. Accordingly, neuromodulation protocols are emerging as potentially valuable tools for seizure control. In focal epilepsy, the capacity of cathodal transcranial direct current polarisation to reduce cortical excitability has prompted research into this technique’s antiepileptic potential. Purpose to investigate whether cathodal transcranial direct current polarisation can modify seizure frequency in drug resistant focal epilepsy patients assessed by clinical evaluation, seizure diary and electroencephalography.

Methods: A randomized, double blind, placebo controlled clinical trial on 20 patients diagnosed with multidrug resistant focal epilepsy was enrolled in our study. The patients were randomized into 2 groups. Group A received real 5-day sessions of cathodal tdcs over the area of most frequent interictal epileptiform discharges or the area of suspected ictal onset inferred by MRI findings, ictal EEG and clinical seizure semiology. Group B received sham sessions. Outcome indicators were baseline and post sessions seizure diary as well as EEG (epileptiform discharges were counted per hour).

Results: There were no significant differences in age and gender between patients and controls (p> 0.05). The percentage reduction of epileptiform discharges was greater for real stimulation group versus the placebo group (p= 0.0124). In addition, the percentage reduction of seizure frequency was greater for real stimulation group versus the placebo group (p= 0.0308). It is noted that cathodal direct current stimulation can improve control of focal drug resistant epilepsy patients. Conclusion our study shows that cathodal tdcs is a promising therapeutic tool for short term seizure reduction in chronic drug resistant focal epilepsy patients.

 

Joey Gaines

Title: Life after seizures and neurosurgery

Time : 12:30-12:50

Speaker
Biography:

Joey Gaines was born a perfectly healthy baby boy May 15, 1967, the last of 4 children. Epilepsy was not listed in the familial health history. At age 2, he became ill running a high fever causing seizures. It was not until puberty that it became clear that he had been affected by the illness as a toddler. He became afflicted with grand mal and complex partial seizures. After high school he went to work for his uncle and became a skilled craftsman, a 100 % x-ray welder. He retained his ability to weld even after the surgery and has been actively working his craft for 33 years.

 

Abstract:

A febrile seizure began the 30 year journey from captivity of seizures to freedom after neurosurgery: Left Anterior Temporal Lobectomy/ Left Hippocampus removal had to be considered for best end result. 80% of patients after surgery were seizure free  one year post op and 90% showed marked improvement.(neuro.mcg.eduepisurg.htm)  It was suspected that he had been having petite mal seizures all along. At age 14 and 16 years of age, he experienced seizure activity that put him into a coma for 3 days leaving him with some memory loss. By the time the “subject” was 32, medication was no longer effective, having approximately 800 seizures a year. It was determined at this time that surgery was his only option if he was to continue to live. Because of the extent of the surgery, it was thought it would leave him a nonfunctioning adult that he would be bound to a wheelchair and unable to care for himself, when he opened his eyes after surgery he had no memory. No memory of the ability to function in everyday living, or who or what people surrounding him in hospital were. He had no memory of family or friends, that he had children or a wife and had difficulty retaining short term memory without continual repetition. But he learned again how to eat, walk, use the toilet and care for his personal needs. He returned to work, drives and lives on his own. The one thing he did retain was his craft as a master welder.

Abstract:

Lennox-Gastaut syndrome (LGS) is an epileptic encephalopathy defined by a triad of multiple drug-resistant seizure types, a specific EEG pattern showing bursts of slow spike-wave complexes or generalized paroxysmal fast activity, and intellectual disability. The prevalence of LGS is estimated between 1 and 2% of all patients with epilepsy.The relationship between sleep disturbances and refractory epileptic encephalopathies (EEs) are still scarce. The aim was to assess, by means of nocturnal polysomnography, if children with LGS present with objective alterations in sleep macrostructure.33 children with LGS  (21 males; mean age: 7.9 ± 1.4 years) and 33 healthy controls (22 males; mean age: 8.1 ± 1.1 years) underwent an overnight full polysomnography (PSG). Relative to controls, children with LGS showed a significant reduction in all PSG parameters related to sleep duration time in bed (TIB-min; p< 0.001), total sleep time (TST-min; p<0.001), and sleep percentage (SPT-min;  p <0.001), as well as significantly higher REM latency (FRL-min p<0.001), rate in stage shifting (p = 0.005), and number of awakenings/hour (p = 0.002).Relative to controls, children with EEs also showed significant differences in respiratory parameters (AHI/h, p<0.001; ODI/h, p<0.001; SpO2%, p<0.001; SpO2 nadir%, p<0.001) and a higher rate of periodic limb movements with an index per hour >5 (PLMs%, p<0.001).Our findings suggest that sleep evaluation could be considered mandatory in children with Lennox-Gastaut syndrome  in order to improve the clinical management and the therapeutic strategies.

Ivan Pigarev, electrophysiologist, graduated from biological department of Moscow State University in 1963. Since that time till the present he is working in the Institute for Information Transmission problems (Kharkevich Institute) of Russian Academy of Sciences in Moscow, at present as leading scientist. His studies were mainly concentrated in the field of vision. Since 1991 Pigarev began to investigate sleep. He proposed and confirmed by direct experiments the visceral theory of sleep according to which cortical sensory areas during sleep switch to processing of the visceral information thus supporting animal homeostasis. Pigarev has published more than 90 papers.

 

Abstract:

Vagus nerve stimulation is widely used for seizure prevention in otherwise incurable epilepsy. Vagus nerve is engaged in bidirectional information transfer between internal organs and the brain, but how activity of the visceral pathways may be related to paroxysmal events in the brain remained unclear.  It has been recently shown that during sleep signals from internal organs are directed towards all areas of the cerebral cortex for comprehensive analysis and restoration of body functionality. Visceral organs often have rhythmic activity and neuronal messages from such organs to the cerebral cortex are also rhythmic. Epileptogenic effect of rhythmic sensory stimulation is well known. Thus it is possible that during developing sleep and in deep sleep rhythmic visceral afferentation may provoke paroxysmal activity in cerebral cortex. Stimulation of vagus nerve can change the frequency of this seizure-promoting activity of internal organs from the resonance range thereby blocking paroxysmal activity. Proposed mechanism of epileptiform activity resulting from visceral signaling do not exclude that paroxysmal activity can be initiated in otherwise healthy brain. The cause of this type of epileptic events may be related to a deviation from the normal rhythmical working of some internal organs and transmission of these signals to the cerebral cortex during local or total sleep.

Abstract:

Malformations of cortical development (MCD) are a group of developmental disorders frequently causing epilepsy. Although next generation sequencing can help identify substantial genetic variants, a correct genetic diagnosis of MCD relies on the correlations with neuropathology. I will report the genetic landscape of MCD with refractory epilepsy (RE) whose diagnosis were firmly established in a multidisciplinary epilepsy team at Taipei Veterans General Hospital in Taiwan. Sixty-six patients were recruited. Their MCD types include: FCD (51, 77.3%), heterotopia (4, 6.06%), polymicrogyri, Dandy-Walker malformation and lissencephaly. Tuberous sclerosis complex was not included. These patients were first screened by targeted sequencing (TS) of 66 genes causative for MCD and epilepsy encephalopathy. For those with a potential candidate variant identified, they were submitted to whole exome sequencing to confirm the variant is the best pathogenic candidate. Reported pathogenic variant or novel but potentially disease-causative variants were identified in 28 patients (42%). Among them, nine were familial cases (32%). In the 38 genetic not-assigned individuals, only two had a positive family history (5.3%). Nine variants (32/1%) occurred in the GATOR1 complex genes (DEPDC5/NPRL2/NPRL3). The hit rate was the highest, reaching 78% (7/9), in severe and diffuse MCD, like Dandy-Walker malformation and lissencephaly. For FCD, the hit rate was 55% (28/51). Our results supported that rapid screening by tTS of known disease-causative genes is efficient to enhance genetic diagnosis of MCD, particularly in severe and diffuse MCD and FCD. Brain MRI and neuropathology are essential to determine the pathogenicity of identified variants.
