Takotsubo cardiomyopathy (TC) is increasingly recognized in neurocritical care population especially in postmenopausal females. We are presenting a 61-year-old African American female with past medical history of epilepsy, bipolar disorder, and hypertension who presented with multiple episodes of seizures due to noncompliance with antiepileptic medications. She was on telemetry which showed ST alarm. Electrocardiogram (ECG) was ordered and showed ST elevation in anterolateral leads and troponins were positive...

BACKGROUND: Dysphoric disorder (DD), characterized by intermittent pleomorphic symptoms, has been believed to be specific to epilepsy. However, our previous study revealed that DD in patients with localization-related epilepsy was associated with a lifetime diagnosis of mood disorders. The present study was conducted to estimate the prevalence of DD in patients with mood disorders, but not epilepsy, and to identify the clinical similarities and differences of DD in patients with either epilepsy or mood disorders...

This review presents the recently published revised classifications of epilepsies and seizure types developed by the International League Against Epilepsy (ILAE). The Classification of Epilepsies includes several diagnostic levels (steps): 1) from seizure type to epilepsy type (generalized/focal/combined generalized and focal/unknown), 2) diagnosis of epilepsy syndrome 3) etiology (genetic/ structural/ infectious/ metabolic/ immune/unknown). A clinician can use any level of the classification. Operational classification of seizure types is replaced by the previous classification that was grounded on the anatomical basis...

Duchenne Muscular Dystrophy (DMD) is the most frequent muscular dystrophy in childhood, with a worldwide incidence of one in 5000 live male births. It is due to mutations in the dystrophin gene leading to absence of full-length dystrophin protein. Central nervous system involvement is well-known in Duchenne Muscular Dystrophy. The multiple dystrophin isoforms expressed in brain have important roles in cerebral development and functioning. The association of Duchenne Muscular Dystrophy with seizures has been reported, and there is a higher prevalence of epilepsy in Duchenne Muscular Dystrophy patients (between 6...

Subclinical rhythmic discharges of adult (SREDA) is a rare benign EEG variant in adults and is of unknown clinical significance. Its occurrence in children is extremely rare. In review of the literature, it has been described in only four children. We present a case of a 10-year-old female with generalized idiopathic childhood absence epilepsy who is noted to have SREDA in three subsequent EEGs performed across a 25-month span. She had no clinical change with these discharges and it was believed to be a benign variant...

One of the standard surgical approaches to lateral ventricular tumors involves interhemispheric dissection along the falx cerebri. The falx cerebri thus provides an important landmark in guiding the surgeon to the midline. Unrecognized absence of falx may lead to surgical complications. A child with tuberous sclerosis presented with refractory epilepsy and a lateral ventricular tumor. The tumor was excised by an interhemispheric trans-callosal approach. The midline falx cerebri was absent anteriorly, rendering the identification of midline difficult...

The state of therapeutic ketosis can be achieved by using the ketogenic diet (KD) or exogenous ketone supplementation. It was suggested previously that the adenosinergic system may be involved in the mediating effect of KD on suppressing seizure activity in different types of epilepsies, likely by means of adenosine A1 receptors (A1Rs). Thus, we tested in the present study whether exogenous ketone supplements (ketone ester: KE, 2.5 g/kg/day; ketone salt/KS + medium chain triglyceride/MCT: KSMCT, 2.5 g/kg/day) applied sub-chronically (for 7 days) by intragastric gavage can modulate absence epileptic activity in genetically absence epileptic Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats...

Absence epilepsy is the neurological disorder characterized by the pathological spike-and wave discharges present in the electroencephalogram, accompanying a sudden loss of consciousness. Experiments were performed on brain slices obtained from young male WAG/Rij rats (2-3weeks old), so that they were sampled before the appearance of brain-damaging seizures symptoms. Two differing brain areas of the rats' brain tissue were studied: the somatosensory cortex (Sc) and the dorsal lateral geniculate nucleus of the thalamus (DLG)...

REVIEW
J Vuong, Annaelle Devergnas
Epilepsy is a network disorder and each type of seizure involves distinct cortical and subcortical network, differently implicated in the control and propagation of the ictal activity. The role of the basal ganglia has been revealed in several cases of focal and generalized seizures. Here, we review the data that show the implication of the basal ganglia in absence, temporal lobe, and neocortical seizures in animal models (rodent, cat, and non-human primate) and in human. Based on these results and the advancement of deep brain stimulation for Parkinson's disease, basal ganglia neuromodulation has been tested with some success that can be equally seen as promising or disappointing...

Absence epilepsy, characterized by 2-4 Hz spike-wave discharges (SWDs), can be caused by pathological interactions within the thalamocortical system. Cortical spindling oscillations are also demonstrated to involve the oscillatory thalamocortical rhythms generated by the synaptic circuitry of the thalamus and cortex. This implies that SWDs and spindling oscillations can share the common thalamocortical mechanism. Additionally, the thalamic reticular nucleus (RE) is hypothesized to regulate the onsets and propagations of both the epileptic SWDs and sleep spindles...

Background Migraine is a well-known feature of mitochondrial disorders (MDs). However, no systematic epidemiological data are available in large populations of patients. Aims The aim of this cross-sectional cohort study was to describe the prevalence and migraine characteristics in a large cohort of patients with mitochondrial encephalomyopathies. Methods We studied 93 consecutive patients with characterised MDs referred to our Neuromuscular Unit during a 12-month period. All patients (age range = 16-78 years; 31 men; 58 progressive external ophthalmoplegia [PEO], 12 myoclonic epilepsy with ragged red fibres [MERRF], eight mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes [MELAS], two mitochondrial neurogastrointestinal encephalomyopathy [MNGIE] and 13 other MDs) underwent a structured diagnostic headache interview using an operational diagnostic tool following the IHS criteria...

The occurrence of a single seizure does not always require initiation of antiepileptic drugs. Risk of recurrent seizures should guide their use. In adults, key risk factors for recurrence are two unprovoked seizures occurring more than 24 hours apart, epileptiform abnormalities on electroencephalography, abnormal brain imaging, nocturnal seizures, or an epileptic syndrome associated with seizures. In children, key risk factors are abnormal electroencephalography results, an epileptic syndrome associated with seizures, severe head trauma, and cerebral palsy...

Tuberous sclerosis complex (TSC) is an autosomal-dominant inheritable neurocutaneous disease due to mutations within the TSC1 and TSC2 genes. Many patients present with West syndrome, a severe epilepsy syndrome characterized by the triad of infantile spasms, an interictal electroencephalogram (EEG) pattern termed hypsarrhythmia (continuous slow activity with an amplitude higher than 300 µV and multiregional spikes/polyspikes/sharp waves) and developmental regression. In this study, we report on a previously healthy patient with positive family history of epilepsy with new-onset epileptic encephalopathy at the age of 9 years...

Introduction  Epidermoid tumors represent approximately 0.3 to 1.8% of all intracranial brain tumors. Only 1.5% of all intracranial epidermoid cysts (ECs) invade the brain and secondary epilepsy is extremely rare. Since August 2014, a 59-year-old male smoker had been presenting bad smell feelings, totaling four episodes with sudden onset and duration of 2 minutes. On September 2014, after a sense of smell episode, it evolved into loss of contact and automatic movements followed by generalized tonic-clonic movements...

Antiepileptic drugs (AEDs) have long been known to affect carnitine metabolism, dropping the plasma free carnitine. Valproate (VPA) was considered to be the strongest carnitine-reducing agent. VPA-induced hyperammonemic encephalopathy and hepatotoxicity are well known, and pre-existing carnitine deficiency can be a predisposing factor, especially in congenital metabolic disorders. Several studies have shown that carnitine supplementation in patients receiving VPA to result in subjective and objective improvements and to prevent VPA-induced hepatotoxicity and encephalopathy, in parallel with increases in carnitine serum concentrations...

In the absence of a culprit epileptogenic lesion, pharmacoresistant seizures should prompt the physician to consider potentially treatable metabolic epilepsies, especially in the presence of developmental delays. Even though the anti-seizure treatment of the epilepsies remains symptomatic and usually tailored to an electroclinical phenotype rather than to an underlying etiology, a thorough metabolic workup might reveal a disease with an etiology-specific treatment. Early diagnosis is essential in the case of treatable metabolic epilepsies allowing timely intervention...

Closed-loop brain stimulation is a promising alternative to treat drug-resistant epilepsies. In contrast to optogenetic interventions, transcranial electrical stimulation (TES) does not require cellular modification of neurons to be effective, and it is less invasive compared to deep brain stimulation. Furthermore, on-demand TES of targeted brain regions allows the potential for normal function of these networks during interictal periods, a possibility that is eliminated by resective surgical treatment approaches...

OBJECTIVE: In mesial temporal lobe (mTL) epilepsy, seizure onset can precede the appearance of a scalp EEG ictal pattern by many seconds. The ability to identify this early, occult mTL seizure activity could improve lateralization and localization of mTL seizures on scalp EEG. METHODS: Using scalp EEG spectral features and machine learning approaches on a dataset of combined scalp EEG and foramen ovale electrode recordings in patients with mTL epilepsy, we developed an algorithm, SCOPE-mTL, to detect and lateralize early, occult mTL seizure activity, prior to the appearance of a scalp EEG ictal pattern...
