According to the seventh report of Joint National Committee (JNC 7), hypertensive emergency (HE), a kind of hypertensive crisis, is defined as a sudden and abrupt elevation in blood pressure so as to cause acute target organ dysfunctions, including central nervous system, cardiovascular system or kidneys. Patients with HE require immediate reduction in markedly elevated blood pressure. Currently, there are no international guidelines for children HE, so the JNC definition is commonly used. Hypertensive emergency in children is rare but a life-threatening emergency...

In the investigation of psychogenic nonepileptic seizures (PNES), the main differential diagnoses are between convulsive PNES and tonic-clonic seizures, between swoon PNES and syncope, and between pseudoabsence PNES and absence seizures. For the best diagnostic certainty, events must be captured, ideally using video-electroencephalogram (EEG), including an electrocardiographic channel. The "video" part of video-EEG allows EEG changes (or lack of them) to be interpreted in the appropriate clinical context. When the diagnosis is based on less good data (e...

Major depressive disorder (MDD) is a frequent and painful mental disorder considered among the five leading causes of disability in Western countries by the World Health Organization. MDD occurs at all ages, but childhood onset MDD has a more severe course with longer depressive episodes, more suicidality, and more frequent hospitalization, than later onset MDD. Childhood seems to be a window of opportunity for prevention of mental disorders, and subsequently prevention of MDD onset in childhood is recommended...

Creutzfeldt-Jakob disease has a higher incidence in Chile than in other countries. The post mortem pathological characterization of brain tissue is necessary to reach a definitive diagnosis. We report a 73 years old man with a history compatible with of a rapidly progressive dementia, in which the first electroencephalographic study showed a pattern consistent with non-convulsive status epilepticus. Besides discarding this diagnosis, it was necessary to rule out other causes of rapidly progressive dementia such as Hashimoto encephalopathy...

Pediatric Status Epilepticus (SE) is an emergency situation with high morbidity and mortality that requires early and aggressive management. The minimum time criterion to define SE was reduced from 30 to 5 minutes, defined as continuous seizure activity or rapidly recurrent seizures without resumption of consciousness for more than 5 minutes. This definition considers that seizures that persist for > 5 minutes are likely to do so for more than 30 min. Those that persist for more than 30 minutes are more difficult to treat...

OBJECTIVE: Most patients with localization-related epilepsy (LRE) and genetic generalized epilepsy (GGE) are classified based on semiology and video-EEG, but both features occasionally fail to provide a definitive diagnosis. Several reliable lateralizing signs have been described, although hand and finger posturing has received little attention. We sought to investigate the frequency of index-finger pointing (IFP) during generalized motor convulsions as a lateralizing semiology in LRE...

Tuberous sclerosis complex (TSC) is a neurocutaneous syndrome, inherited as an autosomal dominant trait with a high incidence of sporadic cases and protean clinical expression, with a incidence of prevalence between 1 in 10,000 and 1 in 170,000. The cardinal features of TSC are skin lesions, convulsive seizures, and mental retardation. We report a sporadically occurring case of definite TSC in a young female who presented with oral and cutaneous manifestations without mental retardation or history of convulsive seizures, which to the best of our knowledge has not been reported so far...

The distinction between acute encephalopathy (AE) and convulsive disorders with pyrexia may be problematic. We analyzed the clinical and laboratory features in 127 children who were admitted for suspected AE. They were categorized into (1) definite acute encephalopathy group (DAEG; n = 17, abnormal findings on electroencephalography [EEG], magnetic resonance imaging, or single-photon emission computed tomography [SPECT] with prolonged impaired consciousness), (2) probable acute encephalopathy group (PAEG; n = 21, abnormal findings without prolonged impaired consciousness), and (3) nonacute encephalopathy group (NAEG; n = 89)...

BACKGROUND: The disability adjusted life year (DALY) is a composite measure of disease burden that includes both morbidity and mortality, and is relevant to conditions such as epilepsy that can limit productive functioning. The 2010 Global Burden of Disease (GBD) study introduced a number of new methods and definitions, including a prevalence-based approach and revised disability weights to calculate morbidity and new standard life expectancies to calculate premature mortality. We used these approaches, and local, population-based data, to estimate the burden of convulsive epilepsy in rural South Africa...

Acute disseminated encephalomyelitis (ADEM) is an immune-mediated monophasic inflammatory demyelinating disorder of the central nervous system which poses a diagnostic challenge. We report on six cases of different etiologies that mimicked the clinical and radiologic findings of ADEM. The cases were collected from four different reference hospitals in Turkey. The same radiologist from the Akdeniz University Faculty of Medicine examined the magnetic resonance images of all patients. Three (50%) patients had antecedent infections...

Status epilepticus is a heterogeneous disorder with varied definitions and presentations. Taken together, all forms of status epilepticus carry significant morbidity and mortality, much of which is dictated by the underlying etiology. Generalized convulsive status epilepticus, which represents a common form, is a true neurologic emergency that requires emergent management. Treatment focuses on stabilizing the patient and aggressive medical management to achieve the timely termination of seizures. For other forms of status epilepticus including nonconvulsive and focal status epilepticus, the goal remains early seizure termination, but the use of intravenous medications should be weighed against the risks associated with these therapies...

Tuberous sclerosis complex (TSC) is known to cause severe intractable epilepsy and mental retardation; however, diagnosis can be delayed in milder cases. We report a 26-year-old right-handed female patient who started having convulsions at age 7 days. She had several focal seizures per year that were intractable to treatment with carbamazepine or phenytoin. Her two sisters had several episodes of suspected epileptic seizures but had no symptoms related to TSC. Seizure semiology of the patient comprised of visual hallucination, loss of consciousness, and convulsive movements predominantly on the right...

PURPOSE OF REVIEW: There have been a considerable number of research articles published in the last 10 years outlining possible advances in the provision of electro-convulsive therapy (ECT) anaesthesia. This has resulted in a range of new drugs having been proposed as useful in the ECT setting. In particular, the use of adjuvant drugs that might improve outcomes to treatment has been investigated. RECENT FINDINGS: There is a high level of interest in ketamine and remifentanil as agents that may alter response in ECT anaesthesia, by reducing cognitive effects, and minimizing the dose of induction agent...

In this study, we assessed 11 patients who were definitively diagnosed with tuberous sclerosis complex (TSC) based on the accepted clinical diagnostic criteria (Roach, 1998). We compared the clinical and radiological findings of six adult-onset TSC cases (group A) and five child-onset TSC cases (group B). The prevalence rates of generalized tonic-clonic convulsions at onset, mental retardation, facial angiofibroma, and epilepsy were lower in group A than in B group. The number of cortical tubers and subependymal nodules on brain magnetic resonance (MR) and computed tomography (CT) images were also lower in group A...

Non-convulsive status epilepticus (NCSE) presents with minimal seizure activity clinically, but with evidence on EEG. It is a recognised cause of delirium in older people, but prevalence estimates vary widely. As delirium is a common presentation in older people and because NCSE is potentially reversible, an improved diagnostic ability in this group could be highly beneficial. EEG testing is required to make a definitive diagnosis, but this may be difficult due to access to testing, patient adherence and result interpretation...

The Commission on Classification and Terminology and the Commission on Epidemiology of the International League Against Epilepsy (ILAE) have charged a Task Force to revise concepts, definition, and classification of status epilepticus (SE). The proposed new definition of SE is as follows: Status epilepticus is a condition resulting either from the failure of the mechanisms responsible for seizure termination or from the initiation of mechanisms, which lead to abnormally, prolonged seizures (after time point t1 )...

BACKGROUND: Rosai-Dorfman disease (RDD) is a rare, idiopathic, non-neoplastic histioproliferative disease. Central nervous system (CNS) manifestations are extremely rare. Its low incidence and unknown etiology restrict early diagnosis and optimal therapy. METHODS: In the 1995-2013 period, seven CNS-RDD patients with intracranial and/or spinal lesions were retrospectively analyzed, including the clinical data, laboratory and imaging results, treatment applied and outcome...

INTRODUCTION: Aicardi syndrome (OMIM 304050) was first described in 1965. Its classic triad consists of infantile spasms, partial or total agenesis of the corpus callosum and ocular disorders, such as chorioretinal lacunae. It has been posited that it is due to a mechanism involving X-linked dominant inheritance. CASE REPORT: We report the case of a full-term female, with no pathological familial history or parental consanguinity, with a prenatal diagnosis of Dandy-Walker type malformation, who presented convulsions, coloboma of the optic nerve, thoracic vertebral block with presence of scoliosis, transfontanellar ultrasound imaging showing agenesis of the corpus callosum and karyotype 46,XX...
