Myoclonic status epilepticus (MSE) is defined as prolonged period of myoclonic jerks that are correlated with epileptiform discharges on EEG. We here describe clinical features and video-EEG records of six adult patients with MSE who did not have a prior diagnosis of epilepsy. In four out of six patients, MSE was precipitated by drugs. Two out of four patients had chronic renal disease and received beta lactam group antibiotics. Two other patients, who described chronic pain, developed MSE while taking pregabalin. One patient who had dementia and family history of juvenile myoclonic epilepsy (JME) developed MSE one month after quetiapine was introduced. Another patient, who had a recent ischemic stroke, developed MSE due to an unknown reason. In these last two patients, an immediate triggering factor was not evident. Myoclonic status epilepticus ceased in five out of six patients after withdrawal of the drugs and/or intravenous antiepileptic treatment. Myoclonic status epilepticus is a rare event in patients without epilepsy. A correct diagnosis and prompt drug discontinuation may reverse this severe and life-threatening condition.

Rasmussen's encephalitis (RE) is a rare neurological disorder of inflammatory aetiology characterised by encephalitis, intractable seizures, hemiparesis, variable motor deficits, and dementia. It is not commonly considered in the clinical differential diagnosis of a patient with a past history of a stroke-like episode presenting with status epilepticus. It is suspected mainly in children in whom the disease is more common. Here we report a case of an adult man presenting with a common symptom of seizure caused by Rasmussen's encephalitis.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) often presents with a history of migraine with aura and eventual manifestations of dementia with unrelenting, repeated cerebral vascular insults. Only 6-10% of patients with CADASIL have been reported to develop seizures, and status epilepticus (SE) is exceedingly rare. Here, we describe a patient who presented with recurrent SE, with eventual biopsy diagnosis of CADASIL. An 80-year-old woman presented to our hospital three times in two years with decreased level of consciousness and subtle intermittent right-sided upper extremity and facial twitching. There was no known significant family history and no past medical history for seizures, stroke, migraine headache, or overt dementia. Electroencephalography revealed recurrent focal seizures with left hemispheric onset and evolution, fulfilling the criteria for focal SE each time. All three admissions required sedation with midazolam to control seizure activity, in addition to high doses of multiple antiepileptic drugs. Brain MRI repeatedly showed extensive abnormalities in the periventricular and deep white matter, subcortical white matter, and bilateral basal ganglia. Skin biopsy was obtained on the third admission, and electron microscopy showed numerous deposits of granular osmiophilic material, which are pathognomonic for CADASIL. Detailed investigations failed to reveal any other etiology for the patient's condition. This case illustrates the potential for nonconvulsive SE to be the sole manifestation of CADASIL. With the appropriate brain MRI findings, CADASIL should be added to the list of rare causes of SE.

Epilepsy is a heterogeneous clinical condition characterized by recurrent unprovoked seizures, their causes and complications. The incidence, prevalence and mortality of epilepsy vary with age, place and time contributing to a variable extent to the burden of the disease. Diagnostic misclassification may have strong impact on personal and societal reflections of the disease in light of its clinical manifestations and the need for chronic treatment. Epilepsy accounts for a significant proportion of the world's disease burden ranking fourth after tension-type headache, migraine and Alzheimer disease. Among neurological diseases, it accounts for the highest disability-adjusted life year rates both in men and in women. Although epilepsy is self-remitting in up to 50% of cases, variable long-term prognostic patterns can be identified based on the response to the available treatments. Epilepsy carries an overall increased risk of premature mortality with variable estimates across countries. Premature mortality predominates in patients aged less than 50 years, with epilepsies due to structural/metabolic conditions, with generalized tonic-clonic seizures, and seizures not remitting under treatment. Among deaths directly attributable to epilepsy or seizures, included are sudden unexpected death in epilepsy (SUDEP), status epilepticus, accidents, drowning, unintentional injuries, and suicide. Somatic and psychiatric disorders prevail in patients with epilepsy than in people without epilepsy. Asthma, migraine and cerebral tumors tend to occur more frequently in younger adults while cardiovascular disorders, stroke, dementia and meningioma predominate in the elderly. As being a fairly common clinical condition affecting all ages and requiring long-term (sometimes lifelong) treatment, epilepsy carries high health care costs for the society. Direct costs peak in the first year after diagnosis and then vary according to the severity of the disease, the response to treatment, and the presence of comorbidity. Although in several countries the costs of epilepsy are met by the national health systems, out-of-pocket costs may be a relevant fraction of the overall costs, especially in countries where the public management of health care is suboptimal or non-existent. Epilepsy strongly affects patients' independence, psychological health and emotional adjustment. Epilepsy impairs all aspects of health-related quality of life. Awareness and attitudes of the public about epilepsy may significantly affect the burden of the disease. All these factors add to the burden of the disease. However, many of the factors implicated in the onset of epilepsy, its course and treatment can be favorably addressed with appropriate strategic plans. More research is needed to investigate and manage the medical and psychosocial implications of epilepsy.

The aim of this systematic review was to describe particularities in epidemiology, outcome, and management modalities in the older adult population with status epilepticus. There is a higher incidence of status epilepticus in the older adult population, and it commonly has a nonconvulsive presentation. Diagnosis in this population may be difficult and requires an unrestricted use of EEG. Short and long term associated-mortality are high, and age over 60 years is an independent factor associated with poor outcome. Stroke (acute or remote symptomatic), miscellaneous metabolic causes, dementia, infections hypoxemia, and brain injury are among the main causes of status epilepticus occurrence in this age category. The use of anticonvulsive agents can be problematic as well. Thus, it is important to take into account the specific aspects related to the pharmacokinetic and pharmacodynamic changes in older critically-ill adults. Beyond these precautions, the management may be identical to that of the younger adult, including prompt initiation of symptomatic and anticonvulsant therapies, and a broad and thorough etiological investigation. Such management strategies may improve the vital and functional prognosis of these patients, while maintaining a high overall quality of care.

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. Finally, the sustained clinical deterioration with no response to anticonvulsants and corticosteroids, the imaging studies, a serial electroencephalographic monitoring study and the detection of 14-3-3 protein in cerebrospinal fluid were the keys to achieve the diagnosis of the disease.

Down's syndrome (DS; also known as trisomy 21; T21) is caused by a triplication of all or part of human chromosome 21 (chr21). DS is the most common genetic cause of intellectual disability attributable to a naturally-occurring imbalance in gene dosage. DS incurs huge medical, healthcare, and socioeconomic costs, and there are as yet no effective treatments for this incapacitating human neurogenetic disorder. There is a remarkably wide variability in the 'phenotypic spectrum' associated with DS; the progression of symptoms and the age of DS onset fluctuate, and there is further variability in the biophysical nature of the chr21 duplication. Besides the cognitive disruptions and dementia in DS patients other serious health problems such as atherosclerosis, altered lipogenesis, Alzheimer's disease, amyotrophic lateral sclerosis (Lou Gehrig's disease), autoimmune disease, various cancers including lymphoma, leukemia, glioma and glioblastoma, status epilepticus, congenital heart disease, hypotonia, manic depression, prostate cancer, Usher syndrome, motor disorders, Hirschsprung disease, and various physical anomalies such as early aging occur at elevated frequencies, and all are part of the DS 'phenotypic spectrum.' This communication will review the genetic link between these fore-mentioned diseases and a small group of just five stress-associated microRNAs (miRNAs)-that include let-7c, miRNA-99a, miRNA-125b, miRNA-155, and miRNA-802-encoded and clustered on the long arm of human chr21 and spanning the chr21q21.1-chr21q21.3 region.

Creutzfeldt-Jakob disease (CJD), the most common form of human prion diseases, is a fatal condition with a mortality rate reaching 85% within one year of clinical presentation. CJD is characterized by rapidly progressive neurological deterioration in combination with typical electroencephalography (EEG) and magnetic resonance imaging (MRI) findings and positive cerebrospinal spinal fluid (CSF) analysis for 14-3-3 proteins. Unfortunately, CJD can have atypical clinical and radiological presentation in approximately 10% of cases, thus making the diagnosis often challenging. We report a rare clinical presentation of sporadic CJD (sCJD) with combination of both expressive aphasia and nonconvulsive status epilepticus. This patient presented with slurred speech, confusion, myoclonus, headaches, and vertigo and succumbed to his disease within ten weeks of initial onset of his symptoms. He had a normal initial diagnostic workup, but subsequent workup initiated due to persistent clinical deterioration revealed CJD with typical MRI, EEG, and CSF findings. Other causes of rapidly progressive dementia and encephalopathy were ruled out. Though a rare condition, we recommend consideration of CJD on patients with expressive aphasia, progressive unexplained neurocognitive decline, and refractory epileptiform activity seen on EEG. Frequent reimaging (MRI, video EEGs) and CSF examination might help diagnose this fatal condition earlier.

We herein report a 67-year-old female who presented with progressive dementia and disturbance of consciousness. Brain CT showed multiple subcortical calcifications with edema. Enhanced CT showed multiple abnormal vessels in the left hemisphere. Electroencephalography indicated diffuse spike and slow wave complex, so non-convulsive status epilepticus was diagnosed. Cerebral angiography revealed several feeder arteries with retrograde leptomeningeal venous drainage. We diagnosed her with Borden type III cerebral dural arteriovenous fistulas. Trans-arterial embolization with n-butyl-2-cyanoacrylate was performed, and she has experienced no epileptic attacks for at least ten months. Calcification changes are sometimes seen in Borden type II dural arteriovenous fistulas but not in aggressive types, such as Borden type III. It is important to suspect dural arteriovenous fistulas when we encounter patients with progressive dementia or/and epilepsy with cerebral calcification lesions, as this may be a treatable disease condition.

In this study we report the clinical features of 32 patients with gamma aminobutyric acid B receptor (GABABR) antibodies, identify additional autoantibodies in patients with anti-GABABR encephalitis that mark the presence of an underlying small cell lung carcinoma and optimize laboratory methods for the detection of GABABR antibodies. Patients (n = 3225) were tested for the presence of GABABR antibodies using cell-based assay, immunohistochemistry and live hippocampal neurons. Clinical data were obtained retrospectively. Potassium channel tetramerization domain-containing (KCTD)16 antibodies were identified by immunoprecipitation, mass spectrometry analysis and cell-based assays. KCTD16 antibodies were identified in 23/32 patients with anti-GABABR encephalitis, and in 1/26 patients with small cell lung carcinoma and Hu antibodies, but not in 329 healthy subjects and disease controls. Of the anti-GABABR encephalitis patients that were screened sufficiently, 18/19 (95%) patients with KCTD16 antibodies had a tumour versus 3/9 (33%) anti-GABABR encephalitis patients without KCTD16 antibodies (P = 0.001). In most cases this was a small cell lung carcinoma. Patients had cognitive or behavioural changes (97%) and prominent seizures (90%). Thirteen patients developed a refractory status epilepticus with intensive care unit admittance (42%). Strikingly, 4/32 patients had a rapidly progressive dementia. The addition of KCTD16 to the GABABR cell-based assay improved sensitivity of the in-house fixed cell-based assay, without loss of specificity. Twenty-two of 26 patients improved (partially) to immunotherapy or chemotherapy. Anti-GABABR encephalitis is a limbic encephalitis with prominent, severe seizures, but patients can also present with rapidly progressive dementia. The co-occurrence of KCTD16 antibodies points towards a paraneoplastic origin. The addition of KCTD16 improves the sensitivity of the cell-based assay.
