The World Health Organisation has pointed that a successful health care delivery, requires effective medical devices as tools for prevention, diagnosis, treatment and rehabilitation. Several studies have concluded that longer monitoring periods and outpatient settings might increase diagnosis accuracy and success rate of treatment selection. The long-term monitoring of epileptic patients through electroencephalography (EEG) has been considered a powerful tool to improve the diagnosis, disease classification, and treatment of patients with such condition...

BACKGROUND: An increasing amount of evidence suggests an association between epilepsy and multiple somatic and psychiatric conditions, which is more significant than in the general population. Furthermore, a bidirectional association has been established between epilepsy and several conditions, notably depression and suicide, cerebrovascular disease, stroke, dementia and migraine, which is best explained by the presence of common underlying mechanisms and risk factors. Gaining knowledge about these common mechanisms can provide insight into new therapeutic targets, screening and preventive measures...

BACKGROUND: Epilepsy is a serious brain disorder characterized by recurrent unprovoked seizures. Approximately two-thirds of seizures can be controlled with antiepileptic medications (Kwan 2000). For some of the others, surgery can completely eliminate or significantly reduce the occurrence of disabling seizures. Localization of epileptogenic areas for resective surgery is far from perfect, and new tools are being investigated to more accurately localize the epileptogenic zone (the zone of the brain where the seizures begin) and improve the likelihood of freedom from postsurgical seizures...

This study investigated psychotropic medication usage in two large, cohorts of people with autism spectrum disorder (ASD) throughout the calendar year 2014. The cohorts referred to individuals with commercial (employer-sponsored) and Medicaid insurance in the United States. We aimed to understand prescribing patterns of such medications across a wide age-range and in the presence/absence of other clinical and non-clinical characteristics, including psychiatric comorbidities. We described the prevalence and length of prescriptions by age, psychiatric comorbidity and overall...

BACKGROUND: Electrode placement in epilepsy surgery seeks to locate the sites of ictal onset and early propagation. An invasive diagnostic procedure, stereoelectroencephalography (SEEG) is usually implemented with frame-based methods that can be especially problematic in young children. OBJECTIVE: To evaluate the feasibility and accuracy of a new technique for frameless SEEG in children using the VarioGuide® system (Brainlab AG, München, Germany). METHODS: A frameless stereotactic navigation system was used to implant depth electrodes with percutaneous drilling and bolt insertion in pediatric patients with medically refractory epilepsy...

OBJECTIVE: The study provides updated information about the distribution of seizures, epilepsies, and etiologies of epilepsy in the general child population, and compares the old and new classification systems from the International League Against Epilepsy (ILAE). METHODS: The study platform was the Norwegian Mother and Child Cohort Study. Cases of epilepsy were identified through registry linkages and sequential parental questionnaires. Epilepsy diagnoses were validated using a standardized protocol, and seizures, epilepsies, and etiologies were classified according to the old (ILAE 1981/1989) and new (ILAE 2017) classifications...

BACKGROUND: Although anterior temporal lobectomy may be a definitive surgical treatment for epileptic patients with mesial temporal sclerosis, it often results in verbal, visual, and cognitive dysfunction. Studies have consistently reported the advantages of selective procedures compared with a standard anterior temporal lobectomy, mainly in terms of neuropsychological outcomes. OBJECTIVE: To describe a new technique to perform a selective amygdalohippocampectomy (SAH) through a transpalpebral approach with endoscopic assistance...

Despite significant progress in developing new drugs for seizure control, epilepsy still affects 1% of the global population and is drug-resistant in more than 30% of cases. To improve the therapeutic efficacy of epilepsy medication, a promising approach is to deliver anti-epilepsy drugs directly to affected brain areas using local drug delivery systems. The drug delivery systems must meet a number of criteria, including high drug loading efficiency, biodegradability, neuro-cytocompatibility and predictable drug release profiles...

OBJECTIVE: Some medical problems, such as syncope, have direct consequences for fitness to drive. Our objective was to discover if patients had been informed about their driving status after a syncopal episode by their physician, and if this advice was in line with current legislation. DESIGN: Cross-sectional study. METHOD: By means of a structured questionnaire, 150 patients referred to the syncope clinic at the Academic Medical Centre, Amsterdam, were asked about the advice they had received concerning their driving status during previous consultations with their general practitioner or specialists...

INTRODUCTION: One-third of patients with refractory epilepsy may be candidates for resective surgery, which can lead to positive clinical outcomes if efficiently managed. In Australia, there is currently between a 6-month and 2-year delay for patients who are candidates for respective epilepsy surgery from the point of referral for surgical assessment to the eventual surgical intervention. This is a major challenge for implementation of effective treatment for individuals who could potentially benefit from surgery...

OBJECTIVE: There are no evidence-based guidelines on the preferred approach to treating early-life epilepsy. We examined initial therapy selection in a contemporary US cohort of children with newly diagnosed, nonsyndromic, early-life epilepsy (onset before age three years). METHODS: Seventeen pediatric epilepsy centers participated in a prospective cohort study of children with newly diagnosed epilepsy with onset under 36 months of age. Details regarding demographics, seizure types, and initial medication selections were obtained from medical records...

First part of this review (Chapter 1) demonstrates an ambiguous attitude toward psychiatry among professionals and in society in recent decades. The articles of supporters and opponents of psychiatry are also quoted. The authors describe the dynamics of the reflection of psychopathology in the main widely accepted classifications and manuals. Critical and negative opinions regarding the DSM-5, due to its role in the 'medicalization' processes, for the movement 'World Mental Health', are mentioned. The history of antipsychiatry movement and its results for psychiatry and society are analyzed as well...

In recent years, the source localization technique of magnetoencephalography (MEG) has played a prominent role in cognitive neuroscience and in the diagnosis and treatment of neurological and psychological disorders. However, locating deep brain activities such as in the mesial temporal structures, especially in preoperative evaluation of epilepsy patients, may be more challenging. In this work we have proposed a modified beamforming approach for finding deep sources. First, an iterative spatiotemporal signal decomposition was employed for reconstructing the sensor arrays, which could characterize the intrinsic discriminant features for interpreting sensor signals...

BACKGROUND: The frontal aslant tract (FAT) is a deep frontal pathway connecting the superior frontal gyrus (SFG) to Broca's area. This fiber is assumed to be associated with language functions, especially speech initiation and spontaneity. OBJECTIVE: The aim of this study was to electrophysiologically investigate this network using cortico-cortical evoked potentials (CCEPs). METHOD: Eight patients with brain tumors or medically intractable focal epilepsies who underwent frontal craniotomy over the language dominant side were enrolled in this study...

Seizures are a common co-morbidity during the course of Alzheimer's disease (AD) and in a subset of patients may be one of the presenting symptoms. In this case series, we highlight three patients with recurrent medically refractory epileptic auras whose work up ultimately lead to the diagnosis of AD. All three patients underwent prolonged EEG, serial neuropsychological testing, FDG-PET, cerebrospinal fluid (CSF) AD biomarkers, and MRI. CSF biomarkers were particularly helpful in two cases. These cases highlight the importance of having a high index of suspicion for AD in new onset "idiopathic" epilepsy in the elderly...

We present the results of an 18-month study of a new model of how to care for emergency neurological admissions. We have established a hyperacute neurology team at a single district general hospital. Key features are a senior acute neurology nurse coordinator, an exclusively consultant-delivered service, acute epilepsy nurses, an acute neurophysiology service supported by neuroradiology and acute physicians and based within the acute medical admissions unit. Key improvements are a major increase in the number of patients seen, the speed with which they are seen and the percentage seen on acute medical unit before going to the general wards...

Treatment of TBI remains a major unmet medical need, with 2.5 million new cases of traumatic brain injury (TBI) each year in Europe and 1.5 million in the USA. This single-center proof-of-concept preclinical study tested the hypothesis that pharmacologic neurostimulation with proconvulsants, either atipamezole, a selective α2-adrenoceptor antagonist, or the cannabinoid receptor 1 antagonist SR141716A, as monotherapy would improve functional recovery after TBI. A total of 404 adult Sprague-Dawley male rats were randomized into two groups: sham-injured or lateral fluid-percussion-induced TBI...

In the wake of successive cases of fatal accidents caused by patients behind the wheel whose driving was likely to be hindered due to paroxysmal diseases, including epilepsy, there has been an outcry from victims demanding stricter criminal penalties against the perpetrators due to negligence. As a result of this action, a revised Road Traffic Act was put into effect in Japan on June 14, 2013. This act established new penal provisions against any person who provides false statements on his/her medical condition(s) when acquiring or renewing a driver's license...
