The Epilepsy Center (EC) is considered as reference for referring epilepsy patients from around the country, particularly those that are difficult to diagnose or present forms of refractory epilepsy. EC makes efforts to the promotion and prevention of epilepsy, and intervention for most patients with epilepsy regain health. Not confined to hospital care, but strategies are designed to reach the community. The proposed actions produce results in the short term. Epilepsy and PharmacologyThe 61% of patients have adverse drug reactions (ADR) with antiepileptic drugs (AED), in 40% determining discontinuation due to toxicity.The goal in treating epilepsy is control seizures, but also prevents adverse events (AE). International League Against Epilepsy (ILAE) has recognized AE assessing outcome in epilepsy treatment. Among the most frequent ADR are cognitive changes and their impact on quality of life. Few studies have assessed them using neuropsychological test. Other frequent AE are severe adverse skin reactions, especially DRESS. Clinical judgment is sufficient to evaluate AE. However, there are AE that rely on patient's subjective complaints and systematic questionnaire. There is underreporting of AE. A checklist allows systematic monitoring of AE produced by AED. We evaluate cognitive changes and their impact on quality of life, the occurrence of rash and a checklist to increase reports of AE to reduce morbidity, promoting rational use of AED. Investigation of Genetics Factors Contributing to Diagnosis and Treatment of EpilepsyEpilepsy is one of the most prevalent neurological disorders, affecting about 3% of world population. Even though, the vast majority of patients respond well to different anti-epileptic drugs, there remain a 30% of subjects non-responsive to medical treatment. It is still not completely understood the reason and mechanisms involved in the so-called phenomenon of drug-resistance in epilepsy. Genetic factors could be involved in these processes. Epilepsy secondary to Malformations of Cortical Development is one the frequently drug-resistant syndromes in infancy. We propose to advance in the knowledge of the genetic factor responsible for some of the malformations of cortical development applying classic strategies of molecular genetics as the most news tools such as next generation sequencing in a clinical epileptology setting.Maternity and EpilepsyMore information coming soon...Epilepsy and SleepBiological rhythms are inherent to all living systems. These rhythms are originated within each organism and modulated by environmental stimuli. It has been reported that alteration in these circuits, for example the decrease in the inhibitory GABAergic system, causes a reduction in the CNS epileptogenic threshold. Despite the controversies in the literature on the relationship between epilepsy and sleep, there is evidence to assume that sleep act is a natural protector of epilepsy. With the hypothesis that central biological rhythms are altered in this population, we studied the clinical, EEG, and subjective quality and architecture of nocturnal sleep in patients with seizures only during sleep.Magnetic Resonance Images & Diffusion Tensor Images in EpilepsyMore information coming soon...Malformations of Cortical Development and EpilepsyMalformations of cortical development (MCD) are responsible for a wide spectrum of clinical manifestations that include epilepsy, mental retardation and neurological deficits. MCD are considered the second most common cause of medically refractory partial epilepsy in adults after hippocampal sclerosis. Diagnosis of MCD has notably been improved in the past 2 decades as a result of advances in modern imaging, especially magnetic resonance imaging (MRI), and genetics. Epilepsies that were considered cryptogenic in the past are now recognized as secondary to MCD.A detailed assessment of MRI features allows determining the MCD subtype according to Barkovich classification scheme, which can be summarized by 3 main groups: Group 1: “malformations due to abnormal cell proliferation” Group 2: “malformations due to abnormal migration” Group 3: “malformations due to abnormal cortical organization” Several variables are included in the studies that are conducted in our centre: demographic data and clinical features of epilepsy, EEG findings (both the EEG interictal and ictal EEG video registers) and type of response to treatment. Among epilepsy secondary to alterations of neuronal proliferation, are the focal cortical dysplasia identified by MRI. These patients often lack pharmacological control, considering the surgical alternative. One of the most valuable resources for defining the neural network involved in the epileptogenic zone (EZ) is the high definition electroencephalogram (EEG). Applying mathematical algorithms , solving the “inverse problem”, we try to locate the sources of epileptic discharge. From the field of the dipole we localized interictal spike that best explains the pattern of surface EEG. These source localization techniques are less aggressive and expensive, if proven its usefulness, to facilitate location of EZ and contribute to the understanding of cortical neuronal connectivity. Consciousness and EpilepsyConsciousness is a multifaceted concept is defined as the ability of the person to maintain alertness, attention and knowledge of self and environment. Based on various studies show that it depends on the normal activity of a cortical neural network, particularly large cortical association areas located at the fronto-parietal, and its modulation by subcortical system located at the brain stem and diencephalon.Epileptic seizures are expressed by sudden changes in the behavior of short duration, 1 to 3 minutes, most of the time show disturbance of consciousness, and this is one of the aspects that affect the quality of life of the patients. Despite the different investigations both experimentally and clinically, there is no clear explanation of why this impaired of consciousness happens. The understanding of the underlying mechanisms of consciousness would modify treatments to avoid such disturbance during a crisis. To this end we evaluated demographic variables, characteristics of altered consciousness, the surface and intracerebral EEG records and brain MRI.

The Advanced Center of Intracerebral Recordings (ACIR) is the first center in Latin American to have the necessary equipment for human single cell recording in order to study more precisely the origin of epileptic seizures. The ACIR was inaugurated on August 3rd 2012 and is part of the Epilepsy Center who has dual membership: Neurology Division, Ramos Mejía Hospital and Epilepsy Laboratory, Institute of Cellular Biology and Neuroscience "Prof. Dr. E. De Robertis" (University of Buenos Aires - National Council for Scientific and Technical Research). Single Cell RecordingThe Advanced Center of Intracerebral Recordings count with necessary equipment and human resources capable of register the activation of single neuron. The acquisition of this new technology puts Argentine as one of the few countries in the world (USA, England, France, Germany, Holand), and first in Latin America capable of performing such a study.The Advanced Center of Intracerebral Recordings is part of the Epilepsy Center (EC) of Ramos Mejía Hospital. The EC is a high complexity center for outpatients care, being considered as reference for referring patients from around the country and neighboring countries. The EC counts with a video unit-EEG, where patients are admitted for continuous recording during 7-10 days. Studied populationPatients who do not become seizure-free with the current pharmacological treatments go to EC to perform video-EEG studies, neuropsychological and psychiatric assessment, MRI and fMRI studies, among others. With this studies, the EC specialist can design surgical strategy according each patient.Most of the time, the surgery of epilepsy, which removes the portion of the brain where seizures originate (epileptogenic zone), is the next step of these patients to become seizure-free. In some cases, the information obtain with non-invasive methods is not enough to delimit the epileptogenic zone, for which is explored by intracerebral electrodes in specific areas of the brain which vary from each patient. Thus, for clinical reasons there is the unique opportunity to make a direct recording of brain activity in humans, both large group of neurons and single neurons in patients candidates for epilepsy surgery. EquipmentMotivated by technological advances, the Advanced Center of Intracerebral Recordings has acquired the elite system of Blackrock Neuromed (Utah, USA) for simultaneous recording of 128 channels of microelectrodes and macroelectrodes. Microelectrodes are used for single cell recordings, while macroelectrodes are used for intracerebral EEG (iEEG) recordings. This system, which combines in one device the two type of recordings, improves the conditions used so far in the best centers of the world.The traditional iEEG capture the electrical activity of millions of neurons simultaneously. This new technique used microelectrodes of 40 micrometers thick placed in specific brain areas, which are believed from several clinical studies, could be the epileptogenic zone. Each of these microelectrodes records the activity of a small group of neurons (2-3) and with the use of mathematical algorithms can differentiate the electrical activity of neurons one by one. It is important to note that the placement of the microelectrodes do not imply additional risk, since they are located inside the electrodes normally used for iEEG, protruding 3-4 mm from the end of macroelectrode. Objectives and ImplicationsThe advantage essentially consists in register and differentiate the electrical activity of a single neuron from other, instead of recording the activity of millions of neurons as occurs until now with surface electrodes and intracerebral macroelectrodes.This will not only allow greater accuracy when defining the epileptogenic zone, but also explore new treatments. The higher risk of epilepsy is that it cannot predict. The increased risk of epilepsy is that you cannot predict the onset of the crisis, with an uncertainty factor for patients. Although clinically crises seem to come without warning, there is much evidence that the neural network begins to prepare before what the subject perceives. Therefore, the possibility of such registrations will obtain, applying prediction algorithms, better information on how to prepare the epileptogenic network and possibly in the future, develop treatments that prevent the onset of the seizure. At the same time, this procedure allows research the neurophysiological bases of different cognitive processes, chiefly perception and memory, as well as motor activity. In the patients with epilepsy exist a brain region that functions badly in a specific moment, but then is normalized enabling the comprehension of brain operation. By this, the epilepsy is a model that allows study the cognitive capabilities. Main CollaboratorRodrigo Quian Quiroga. Director of the Centre for Systems Neuroscience & Head of the Bioengineering Research Group, University of Leicester, United Kingdom.Localization and characterization of brain activity sourcesThe overall goal is to develop methods and algorithms to model, locate and characterize the neuronal populations sources of interest in the study human brain functions from electroencephalography (EEG), intracranial EEG and magnetic resonance imaging (MRI). Applications focus locating sources in epilepsy, as well as in the study of normal brain, through the use of event related potentials. The results are contrasted with those obtained by other techniques such as functional MRI (fMRI), diffusion tensor imaging (DTI), clinical correlation of the crisis (video-EEG) and, where feasible, with data from electrical stimulation and cortical resection surgery.Different source localization techniques are used to solve the inverse problem. Realistic models of electrical conductivity are made using finite element method (FEM) and boundary element method (BEM). The distributed or dipolar source models are used depending on the particular application. In order to obtain a greater degree of realism, "Physiologically plausible neural populations models" are used. This gives a different perspective to the modeling of brain activity sources, considering both the nonlinear dynamics of neuronal behavior, as well as the complex network of connections between neuronal populations. These models allow a detailed description of epileptogenic sources, among other parameters controlling connectivity among epileptogenic and non epileptogenic populations.

Nurse Ramos Mejía Hospital External CollaboratorsThis new system, that allow register a single neuron electrical activity was developed in the '70s in the University of California, LA (USA). The arrival to Argentina of this technology was possible thanks to the contribution of the Argentine Physicist Rodrigo Quian Quiroga, head of Biophysicist Department and professor of Bioengineering in the University of Leicester, United Kingdom, who is working with this technique ten years ago.The collaboration with Dr. Quian Quiroga starts in the `90s and in the last year a joint work was initiated to install in Argentina the same setup that is installed in Leicester to single cell recordings during visual perception tasks. Dr. Quian Quiroga possesses a vast experience and has developed the algorithm of spike sorting, which allows to recognize the electrical activity of a neuron particularly differentiating it of the others. During August of 2012, we have counted with the presence of Dr. Quian Quiroga in the EC to attend the inauguration of the Advanced Center of Intracerebral Recordings, and to supervise the setup for the registration with microelectrodes. We have also counted with the contribution of Dr. Bekinschtein, of the MRC-Cognition and Brain Sciences Unit, University of Cambridge, UK, in the study of Local Field Potentials (LFP) and Event-Related Potentials (ERP). At the same time, it will continued with the contribution of Dr. Muravchik, director of the LEICI laboratory, Faculty of Engineering, National University of La Plata, to continue with the study of characterization and locating of sources in epilepsy. Dr. D'Attellis, director of the Department of Mathematics at Favaloro Foundation and director of the Department of Mathematics at National University of San Martín will lead the seizure prediction studies with the obtained data.

The Clinic and Laboratory of Neurogenetics at the Neurology Service in the JM Ramos Mejia Hospital specializes in the care of patients and families affected by central nervous system diseases that have or may have a hereditary basis in its development. Since its inception in 2008, we have carried out simultaneously care, teaching and research in the field of Clinical Neurogenetics. The office works with general neurologists or sub-specialized in different areas of Neurology, offering advice on the diagnosis and genetic counseling of patients and families affected by diseases caused by genetic alterations. Among the various pathologies that are often assisted in the office, familial epilepsies stand out. Furthermore, we can mention spinocerebellar ataxia, Friedreich's ataxia, dystonia, Huntington's disease, and mitochondrial neurometabolic disorders, leukodystrophies and hereditary Polyneuropathies (Charcot -Marie-Tooth). The office works in the Department of Neurology of the Ramos Mejia Hospital in Buenos Aires, Argentina and is led by Dr. Marcelo Kauffman, Medical Neurologist, Master of Medical Molecular Biology. Dr. Dolores González Morón, Dr. Sergio Rodriguez, Quiroga, Dr. Patricia Vega and Dr. Marta Córdoba participate in patient care and research and teaching duties, too. Lines of ResearchStudy of the genetic mechanisms underlying the malformations of cortical development.Hypothesis and general objectiveMany Malformations of Cortical Development (MDC) are caused by genetic defects. Although several genes involved in the pathogenesis of these disorders have been recognized, it is still large the number of subjects with no individualization of MDC genetic etiopathogenesis. Therefore, our hypothesis is that mutations in different functional genes in the development of central nervous system represent a frequent cause of Malformations of Cortical Development and the overall goal of the project is, then, contribute to the knowledge of the mechanisms involved in the genesis of Malformations of Cortical Development, particularly the identification of mutations making aetiopathogenic in a population of patients with them.Research Objectives1. Determine in a population of patients with epilepsy secondary to periventricular nodular heterotopias from Argentina the prevalence of mutations in filamin A (FLNA).2. Discover new pathogenic mutations in FLNA, ARFGEF2, YWHAE and PQBP1 genes in the study of the etiology of epilepsy secondary to periventricular nodular heterotopias. 3. Discover new pathogenic mutations in the doublecortin gene in the study of the etiology of epilepsy secondary to subcortical band heterotopias. 4. Determine in a population of patients with epilepsy secondary to Polimicrogirias from Argentina the prevalence of mutations in the genes encoding Tubulins. Genomic Diagnosis in the study of neurogenetic diseasesHypothesis and objective:Many of the Nervous System Diseases are caused by genetic defects. Although several genes involved in its pathogenesis have been recognized, it is still large the numbers of subjects with neurological disorders without identification of their genetic etiology. On the other hand, new massive genome sequencing technologies are called to produce a paradigm shift in the approach to diagnosis of disease, predicting a noticeable short-term impact on the study of the molecular causes of monogenic disorders. Therefore, our hypothesis is that mutations in different functional genes in the development and function of the nervous system represent a significant etiology of Neurological Disorders and developing a systematic genomic analysis oriented will impact clinical diagnostic practice of Hereditary disorders of the nervous system and the overall goal of the project is, then, contribute to the study of neurogenetic diseases through massive genomic sequencing in a population of patients.Specific objectives:Our specific objective of work is the recognition of new genes involved in the pathogenesis of monogenic neurogenetic disorders familiarly aggregated by using massive genome sequencing platforms. We propose in particular:1. Explore the use of different bioinformatics tools in analyzing data obtained through massive genomic sequencing through the implementation of an algorithm for annotation and classification of genetic variants identified. 2. Generating a meta-tool that combines bioinformatics existing analytical resources correlating usual medical narrative (history), genotypes and biomedical literature. Members. CV Summary

Neurobiological and behavioral aspects in people with epilepsya- Neurobiological aspects of epilepsy, determination of biochemical markers related to brain neuroplasticity in patients with surgical treatment; histological and neurochemical study of tissue removed during surgery.b- Behavioral aspects. Research on the behavioral characteristics that affect the quality of life of patients, determining the presence of disorders plausible treated of interdisciplinary team of Mental Health; comorbidity with mood disorders, anxiety, substance abuse and psychosis and personality disorders. Evaluation of patients with epilepsy surgery. c- Analysis of the prevalence of CNE-P (non-epileptic seizures of psychogenic origin); paroxysmal changes in behavior, sensory perception and / or cognitive activity, simulating generalized or partial seizures, but they are not due to a neuronal discharge, and they are associated with psychiatric disorders. PNES are confused with the epilepsy and are often underdiagnosed. The CNEP require an interdisciplinary approach by Mental Health team. Members

Inhibition of epileptic discharge by high and low frequency stimulation in an experimental model of epilepsyEpileptic seizures involve sudden changes in neuronal activity which interfere with the normal operation of the neural network, expressing through hypersynchronous discharges of neuronal populations affected. In the last decade it has been proposed to deep brain stimulation (DBS) as an alternative treatment for patients who do not become seizure-free with the current pharmacological treatments and cannot undergo resective surgical procedure of the epileptogenic zone. However, it remains to determine the optimum stimulation parameters.In our laboratory, the animals are implanted by stereotaxic surgery with stimulation and recording electrodes. The process of epileptogenesis is studied by applying the kindling model, which consists of a single periodic stimulation in a specific brain area for approximately 30 days, giving rise to the appearance of focal seizures secondarily generalized. Currently, our laboratory applies a variable of this phenomenon called Rapid Kindling (RK). Unlike the kindling, in RK is repeated electrical stimulation several times a day for three consecutive days, accelerating the epileptogenic process. To study the effect of the high (HFS) or low frequency (LFS) electrical activity as a potential inhibitor of seizures, it applies HFS or LFS immediately prior to kindling stimulation. It register the electrical activity of the animal pre- and post-stimulation and its analyzed the behavioral response of the animal, as well as different parameters of the electroencephalogram (EEG). This information allows for the antiepileptogenic effect which could cause the stimulation of high and low frequency, delaying the development of the Kindling phenomenon and reducing the post-discharge. High (HFS) and low (LFS) frequency stimuli act by inhibiting the neural network organization involved in epileptogenesis, thus preventing hypersynchronous discharges. Members
