Abstract:
Primary headaches, particularly those that are recurrent or chronic, in childhood are increasingly being recognized as a significant neurologic health problem. The high incidence and prevalence of headaches in the pediatric population has a significant impact on children and their families. To improve the diagnosis of headache and to establish a standardized set of criteria to serve as a common basis for the additional scientific study of headaches, the International Classification of Headache Disorders (ICHD) was developed and is now in its third edition (ICHD-3b).
The ICHD-3b is divided into three major categories: primary headaches, those that are diseases by themselves; secondary headaches, those caused or exacerbated by a secondary factor, and the cranial neuropathies; and other facial pains and headaches.
One essential clarification that was noted in ICHD-3b is that all headache diagnoses that a patient meets should be included in the diagnostic list for that patient (e.g., migraine without aura, migraine with aura, chronic migraine, acute posttraumatic headache). In this way, the full phenotype of the patient can be recognized. Migraine remains under-recognized, under-diagnosed, and ultimately under- or inappropriately treated in this population; this has potential long-term consequences with regards to disease progression.
The underlying pathophysiology is presumably the same as in adults, but the presenting symptoms in a developing brain are often different, especially in children. Early effective intervention may prevent progression and lifelong consequences, including the development of comorbidities. The prevalence of migraine in children age 11 to 13 is estimated to be between 6.1 and 13.6 per 100 and for tension-type headache between 9.8 and 24.7 per 100. These common disorders are often accompanied by significant disability, impacting the child's life and school performance. Early diagnosis and an integrative treatment approach are essential to minimize the impact on a child's quality of life. In addition, differentiating primary headaches from those caused by underlying, perhaps life-threatening pathology is critical to expedient establishment of appropriate treatment and, potentially, cure.
Here we address the key issues of: using practical diagnostic criteria for clinical practice, which acute medication should be chosen, when to use preventive therapy in childhood, and which preventive therapies have the best therapeutic index.

Keynote: A low molecular weight GAPDH binder reduces secondary damage after traumatic brain injury on rats
Time : 11:00 - 11:45
Biography:
Vladimir Lazarev has completed his PhD at the age of 25 years from Institute of Cytology (RAS) and postdoctoral studies were continued at the same place. Now he is the senior reseacher in the Laboratory of cell protection mechanisms. He has published over 20 papers in reputed journals is a supervisor of several students and has been serving as an editorial board member of repute.
Abstract:
Extensive death of neurons can be caused by neurodegenerative pathologies or massive cell damage due to ischemia or traumatic brain injure (TBI). Such pathological conditions lead to the emergence of various proteins in the intercellular space. These proteins can regulate the development of secondary damage due to a clearly expressed toxic effect on the surrounding cells. In this work, we demonstrated the possibility of inhibiting the cytotoxic effect of such aggregates by treatment with specific drug that bind the GAPDH protein, a well-known participant of aggregation, in the intercellular space. Selected chemical – hydrocortisone derivative RX624 prevented the interaction of exogenous GAPDH with cell membrane and reduced the death of the acceptor cells. We also demonstrated efficiency of RX624 treatment on rat model of TBI. This chemical blocked formation of GAPDH aggregates, inhibited cytotoxic effects of cerebrospinal fluid and rescue motor function of injured rats. Importantly, that RX624 treatment of rats had the similar effect with specific anti-GAPDH antibodies intracranial injection.

Keynote: MentalPlus Digital Game for Cognitive Evaluation in Psychiatric Disorders
Time : 11:45- 12:30
Biography:
Prof. Dr. Valentin has completed her Ph.D. at the age of 39 years from University of São Paulo School of Medicine and Duke University and postdoctoral studies from Harvard Medical School. She is the Principal Investigator of MentalPlus Project, the International and Multicentric Study linked at National Institute of Health (NIH) and registered in the clinicaltrials.gov under number NCT 02551952. She has published several papers in renowned journals and has been serving as an editorial board member of repute whose main topics are psychology, psychiatry, neurosciences, anesthesiology, neuropsychiatry, and cardiology.
Abstract:
We know that many psychiatric and neurological disorders affect cognition such as senile illnesses, mood changes, external factors such as surgical interventions, anesthetic procedures, cardiorespiratory arrest, and organic diseases such as diabetes and hypertension. Concerned about this factor, we, a group of neuroscientists involved with health and technology, developed the digital game MentalPlus. This game was created to evaluate and rehabilitate cognitive functions in a playful and fast way since other neuropsychological tests traditionally (paper) evaluate the same functions for a very long period, approximately 3 hours. The MentalPlus digital game assesses memory, visual perception, attention, and inhibitory control of executive functions in just 25 minutes. It has 12 different themes so that the professional can evaluate, rehabilitate and reassess a person without incurring the possibility of the test presenting the learning effect. The only learning it provides is the greater ability in handling a tablet for people who do not master these features. The digital game MentalPlus is in several countries: Thailand; Egypt; Japan; United States; Denmark; Netherlands; Brazil, Portugal. Being studied in Clinical Trials for several pathologies such as Attention Deficit and Hyperactivity Disorder (ADHD), Depression, General and Cardiac Surgeries with the use of deep anesthesia, Perthes Syndrome, Learning Difficulties and the cognitive evaluation for normalization and validation of the results of the game in healthy people from 8 years to 80 years of age. The digital game MentalPlus is also being used as an aid to other techniques for cognitive rehabilitation, as in the concomitant use with Transcranial Current Stimulation - tDCS for the improvement of the attentional, mnemonic and executive functions. The digital game is self -explanatory and can be used offline, and it offers graphics and tables with the player's scores and cognitive performance if you are a health professional or education and researcher and would like to be part of our team; welcome!

Abstract:
R.O.G.E.R (Realistic Observation in Game and Experiences in Rehabilitation) is a virtual reality software. It was developed by a video game company (Fishing Cactus), in collaboration with researchers in neuropsychology (University of Brussels) and neuropsychologists (ERASME Hospital). The purpose of this software is to gather cognitive assessment scale and rehabilitation into a virtual house.
This software can be used in cognitive laboratories or rehabilitation services (i.e. neurology) by several therapists (neuropsychologists, physiotherapists, speech therapists, occupational therapists ...). It is also possible to combine the software with physiological measurements which can record and analyze data during each session (eye-tracker, electrodermal activity, electro-encephalogram ...). Thus, we can obtained precise measurements and guarantee the standardization of the evaluation.The R.O.G.E.R. software offers the possibility for patients to evolve in a safe environment (a complete house with 10 rooms, a garden and 300 objects), and the graphic quality enable a complete immersion and easier transfers in real life situations.
The software integrates an ergonomic scenario editor, which does not required sophisticated computer programming knowledge. The scenario editor enable therapists and researchers to create personalize scenarios for each patient.
R.O.G.E.R promises a graphic quality, accessible for all therapists and neuroscientists, and offers the possibility to work with all cognitive functions and to provide new data for the clinical and the research field.

Abstract:
The knowledge of modern Neuroscience has allowed to identify the origin of some neurodegenerative diseases, thus contributing to the development of more effective therapeutic and surgical strategies that are providing the affected people with greater independence and a better quality of life. In addition, this neuroscientific knowledge is providing relevant psychosocial knowledge and a better understanding of the human being, a field of action of Social Work.
Both the knowledge of modern Neuroscience and its contribution to social problems, as well as to behavioral phenomena and to the human condition at large, has important consequences for mental health and social well-being. It is therefore essential knowledge for the practice of health social workers. Such neuroscientific knowledge provides a new way of examining and addressing problems and can help them to improve their interventions with the different people they assist.
Health social workers are the health field professionals who deal with the psychosocial aspects of patients; in this case, patients with neurodegenerative diseases such as Alzheimer's, Parkinson's, Multiple Sclerosis, Neuromuscular Diseases or ALS (amyotrophic lateral sclerosis). Therefore, it is essential that they have training on the most basic aspects of the human brain, such as: structure, functioning, how, the influence of psychosocial factors develops how it becomes ill or the treatments that can be used.
The pairing of Health Social Work and Modern Neuroscience means having more efficient and better trained professionals, and therefore, offering a higher quality psychosocial care to patients with neurodegenerative diseases.

Abstract:
Insulin dependent diabetes Mellitus (IDDM) is a common condition in children and adolescents worldwide and so is epilepsy. Recently, there were increasing reports suggesting a potential association between 1DDM and the occurrence of epilepsy. Their association might represent simply a chance to relate their underlying mechanisms. However, the cause-effect relationship is not well defined. IDDM pediatric patients have characteristic clinical and biochemical features, including the positivity of glutamic acid decarboxylase antibodies (anti-GAD 65). Literature from other countries have shown the increased prevalence of seizure disorders in this group of patients. However, despite the high prevalence of this disease in Saudi Arabia, no studies have investigated this relationship. Moreover, literature lacks studies investigating IDDM characteristics contributing to this relationship, including anti-GAD 65. In this study we are aiming to determine the prevalence of epilepsy among IDDM children age <15 years old, and compare the positivity of anti-GAD 65 amongst them. Hence, we tried to establish the presence or absence of a relation between epilepsy in children with diabetes and presence of positive GAD65 Antibodies. This is a retrospective cross-sectional study, involving patients’ survey and files review. We randomly recruited around 300 pediatric patients (age <14) with IDDM from our cohort at pediatric endocrinology clinic of King Fahad Medical City (KFMC). A questionnaire was given to caregivers to determine any history of seizure disorders, followed by retrospective review of patients’ files for anti-GAD 65 positivity. In this talk we present our results and review literatures in this issue.

Abstract:
With the growth of the world population, there is concern about the mental health of the people resulting from the daily agitation, from the demands of the social environment, from the academic and professional milieus. In addition to population growth, there is concern about the aging of this population and with this the mental diseases that affect cognition. But not only aging must concern the minds of neuroscientists as well as the healthy development of children who are discovering and training their cognitive abilities. Therefore, neuroscience is concerned with the human being at all stages of his life, as well as preserving in integrity his physical, emotional and mental health. Thinking about how to find a faster and fun way to evaluate the cognitive functions of humans from the age of 8 years to 80 years, the digital game MentalPlusÒ was created. This game aims to evaluate and also to rehabilitate the mnemonic, attentive, perceptive and executive functions in just 25 minutes which characterizes it different from the other neuropsychological tests that require a long time, sometimes up to three hours to evaluate all these functions together and the most interesting in this game is that it is digital, fun and self-applicable. The MentalPlus digital game provides the evaluator with final graphs of the player's results allowing the understanding of the person's performance during the phases of the game in each evaluated function. The digital game MentalPlus is being studied in several research centers, national (Brazil) and international. Studies in clinical trials are being performed with the MentalPlus Digital Game to investigate its efficiency in evaluating cognitive functions such as postoperative recovery after anesthetic-surgical procedures, after a cardiorespiratory arrest, pathologies such as Autism, Attention Deficit Hyperactivity Disorder (ADHD), Depression, Perthes' disease and academic learning difficulties. The MentalPlus digital game is already in several places in the world: America, Europe, Africa, and Asia. We are interested in new partnerships.

Abstract:
Alzheimer’s disease is a neurodegenerative disorder resulting in gradual decline of mental faculties leading to an almost vegetative state eventually. The study of the synaptic alterations and the dendritic and spine pathology in cortical and subcortical neurons is crucial for the correlation of the steps of the mental deterioration with the morphological changes which may disrupt the harmonious communication between neurons, causing serious mental deficits. In early case of Alzheimer’s disease we attempted to study the morphology of synapses and to estimate the numerical density of synapses per dendritic arbor. In addition we studied the morphology of the dendritic spines, estimating also the spinal density per dendritic branch. The study is based on stereological methods applied in light and electron microscopy on specimens of the cerebellar cortex and the hypothalamus of brains derived from patients who suffered from Alzheimer’s disease in early stages. The numerical density of synapses per dendritic branch was estimated on the basis of dissector counting method. We applied also the physical dissector technique on serial sections studied in transmission electron microscopy. The study revealed tremendous loss of dendritic branches, spines and synapses in AD brains in comparison with normal controls. The synaptic loss in the cerebellar cortex concerned mostly the parallel fibers and the Purkinje cell dendrites. In the hypothalamus the neurons of the suprachiasmatic nucleus demonstrated the most impressive decrease of synaptic density per dendritic branch. The morphological and morphometric alterations estimated by stereological techniques confirm that the mental decline coincides with the numerical decline of the synapses in cortical and subcortical neuronal networks in Alzheimer’s disease.

Abstract:
We studied on meningioma among 614 patients with Brain tumor (consists of meningioma, glioma and pituitary tumor). 145 patients had meningioma. Our results are in various topics:
- Clinical features of meningioma
- Anatomical distribution
- Radiation induced meningioma
- Meningioma and foster Kennedy syndrome
- Meningioma and pseudo foster Kennedy syndrome
- Multiple meningioma
- Post traumatic and skull fracture meningioma
- Cutaneous meningioma
- Meningioma and DVT
- Trigeminal neuralgia and meningioma
- Recurrent meningioma
- Meningioma and thrombosis
We are going on to continue this study. This research project has been held in neurosurgery ward Shariati Hospital and had been scientifically registered. We studied during 6 years on meningioma and in this abstract article, we present a patient with Brain stroke symptoms. In this regard, we aimed to review the unusual sign and symptoms of meningioma, e.g. behavioral change, MS like symptom and symptoms of cerebral infarction. All mentioned signs and symptoms initially seems to be unusual for Brain tumor diagnosis, so we found among our study sample, 4 patients under psychiatric treatment and psychological consultation without any Brain imaging study. Therefore, meningioma can present with varies types of neurological and non-neurological symptoms. Meningioma is an extra axial Brain tumor. In fact, meningioma can push the brain tissue, leads to Brain compression as well as intra cranial portion of internal carotid artery. Since meningioma can involve intra cranial portion of the internal carotid artery, the cerebral blood flow slows and, in this status, a clot formation can occur. Various anatomical types of meningioma like sphenoid wing, frontobasal, temporobasal, olfactory groove can compress intra cranial portion of the internal carotid artery.
We report one case of meningioma presenting with cerebral stroke. A 30 years old woman with right upper extremity weakness and right hand numbness, in physical examination, right hand force was 1/5 worsening during 4 weeks. MRI study reveals cavernous area meningioma and the patient after radiation therapy improved completely. We dedicate radiologic specificities and patient's angiography and discussion of anatomical and clinical properties and behaviors of meningioma in this current case, at oral presentation time. In this case, we had done sufficient modalities to rule out hypercoagulable state or any source of emboli.

Title: Myricetin Reduces toxic Level of CAG Repeats RNA in Huntington’s disease (HD) and Spino Cerebellar Ataxia (SCAs)
Biography:
Eshan Khan is PhD Research Scholar under supervision Dr. Amit Kumar in Discipline of Biosciences and Biomedical Engineering, Indian Institute of Technology Indore, India. He has joined Amit Kumar’s lab in July, 2014 and working on therapeutic approaches targeting (CAG)exp RNA that causes neurological disorders like Huntington’s Disease (HD) and Spino Cerebellar Ataxia (SCAs).
Abstract:
Huntington’s disease (HD) is a neurodegenerative disorder that is caused by abnormal expansion of CAG repeats in the HTT gene. The transcribed mutant RNA contains expanded CAG repeats that translate into a mutant huntingtin protein. This expanded CAG repeat also causes mis-splicing of pre-mRNA due to sequestration of muscle blind like-1 splicing factor (MBNL1), and thus both of these elicit the pathogenesis of HD. Targeting the onset as well as progression of HD by small molecules could be a potent therapeutic approach. We have screened a set of small molecules to target this transcript and found Myricetin, a flavonoid, as a lead molecule that interacts with the CAG motif and thus prevents the translation of mutant huntingtin protein as well as sequestration of MBNL1. Here, we report the first solution structure of the complex formed between Myricetin and RNA containing the 5′CAG/3′GAC motif. Myricetin interacts with this RNA via base stacking at the AA mismatch. Moreover, Myricetin was also found reducing the proteo-toxicity generated due to the aggregation of polyglutamine, and further, its supplementation also improves neurobehavioral deficits in the HD mouse model. Our study provides the structural and mechanistic basis of Myricetin as an effective therapeutic candidate for HD and other polyQ related disorders.

Title: High-Sensitivity Troponin T Predicts Perioperative Adverse Events in Patients undergoing Neurosurgical procedures
Biography:
Arsal Acarbas has completed his Phd from Trakya University of Medical Faculty at 2001. And then postdoctoral studies from Vakıf Gureba Egitim ve Arastırma Hospital from 2002 to 2007. And he is still working at Mugla University of Medical School as Asistant Professor.
Abstract:
Objective: Previous studies have shown that troponin is a valuable predictor of perioperative complications after non-cardiac surgery. However, the relation of preoperative troponin levels with perioperative adverse events have not been well described in patients undergoingneurosurgical procedures. This study aimed to evaluate the impact of preoperative high-sensitivity cardiac troponin T (hs-cTnT) levels on outcome of patients undergoing neurosurgical procedures.
Methods: A total of 2519 patients who were aged over 18 years and undergoing elective neurosurgery between December 2014 and December 2018, were retrospectively evaluated. Patients’ information, including medical and demographic data, routine preoperative laboratory tests including hs-cTnT levels were collected to assess the association between these factors and perioperative adverse events.
Results: Perioperative adverse events occurred in 251 (10.0%) patients. Older patients and those with more comorbid conditions tended to have a higher rate of perioperative adverse events. The preoperative hs-cTnT levels were significantly higher in the individuals that experienced complicated in-hospital course than in those who did not (21.6±8.2 vs 6.3±3.1 ng/L, p < 0.001). Multivariate analysis showed that age (OR: 2.33, 95% CI 1.16-4.35, p<0.01), presence of diabetes (OR: 3.13; 95% CI: 1.15-6.32; p =0.004), and preoperative hs-cTnT > 18.3 ng/L (OR 4.51, 95% CI 2.34–7.82, p < 0.001) were signiï¬cant and independent predictors of perioperative adverse events.
Conclusion: This study showed that higher preoperative hs-cTnT is associated with perioperative adverse events in adult patients undergoing elective neurosurgery.

Title: Prognosticating Traumatic Brain Injury (TBI) - How does admission to Neurosurgical units affect outcome?
Biography:
Conor Gillespie is a third year medical student at the University of Liverpool, UK. His interests in Neurosurgery include Traumatic Brain Injury, prognosticating TBI using age, CRASH and IMPACT models, the effect of admission to a tertiary neurosurgical centre and the outcomes of elderly TBI patients. He works closely with the Consultant Neurosurgeons at the Walton Centre (The only specialist hospital trust in the UK dedicated specifically to Neurology and Neurosurgery) on a variety of research areas, ranging from TBI, Meningioma management and Cranioplasty material development. He is also an academic rep for NANSIG (Neurology and Neurosurgery Interest group, UK).
Abstract:
Introduction: Both CRASH and IMPACT models have been developed in recent years to prognosticate Traumatic Brain Injury (TBI). However, there is no clear evidence as to how acceptance for Neurosurgical intervention to tertiary centres affects outcome compared to other centres. There is also predictive uncertainty with regards to if acceptance affects the ability of CRASH and IMPACT to prognosticate TBI.
Methods: Patients referred to a tertiary neuroscience centre from December 2014-January 2016 with a suspected TBI were retrospectively examined. For each model, the predicted survival and overall outcome were compared to the actual outcome on admission and at 6 months post injury, stratified by patient age and acceptance for Neurosurgical intervention.
Results: 161 patients met the initial criteria; mean age 65 yrs (SD=21). Both CRASH and IMPACT correctly predicted 6-month mortality rates and functional outcomes in most patients (range 61.7-82.4%), with better predictive performance for patients not accepted to the centre (range 84-98%). There was also no significant difference in the initial survival of elderly patients if accepted (78% [95% CI 50.6-104] vs. 81% [95% CI 67.8-94.8] but were lower for those not accepted (24% [95% CI 4.2-43.7] vs. 76% [95% CI 63.5-88.5], p=0.027).
Discussion: The lesser ability of CRASH and IMPACT models to predict outcomes when accepted suggests that acceptance to specialist centres may be able to improve outcome. Patients >65 years also had good survival rates on admission and at 6 months if accepted. This suggests more optimistic treatment and acceptance of appropriate patients should be considered.

Raquel Elisabeth Dumaszak is a graduate in psychology with a master's degree from the University of Brasilia and currently working as a teacher at UniOpet- Curitiba, Brazil
Abstract:
Sleep is essential for mental and physical health, and its alterations or deprivation (SD) can alter several behavioral and cognitive aspects, such as memory, for example. In recent years, much has been observed regarding the diversity of alternatives used to interfere in sleep time. Alcohol, for example, is related as an alternative to manipulate sleep and, in times of leisure, is used to reduce levels of anxiety and stress. However, many are the contradictory evidences regarding the interaction (EtOH) x sleep, and its influences on behavior and cognition, being the object of study of this work, it was observed the behavioral response of rats, in experimental models equivalent to anxiety and memory: open field test (locomotion), elevated plus maze (EPM - anxiety) and “step down” inhibitory avoidance (memory). In a general context, it was observed that the SD, induced the animals to longer dodging time which suggested increased learning, while this experimental condition varied the results for anxiety. EtOH, on the other hand, influenced the reduction of anxiety and learning outcomes according to the association of the experimental conditions, but it was concluded that even in acute and low dose consumption, modify memory, learning and anxiety.
