OBJECTIVE: Clinical absences are now classified as "generalized nonmotor (absence) seizures" by the International League Against Epilepsy (ILAE). The aim of this paper is to critically review the concept of absences and to put the accompanying focal and motor symptoms into the context of the emerging pathophysiological knowledge. METHODS: For this narrative review we performed an extensive literature search on the term "absence," and analyzed the plethora of symptoms observed in clinical absences...

OBJECTIVE: To determine the occurrence of chronic traumatic encephalopathy (CTE) in young adult patients undergoing epilepsy surgery. METHODS: Ten patients who underwent epilepsy surgery were randomly selected for this retrospective study. The patients were 18-45 years of age, had preoperative neuropsychological evaluation, and had 1 year postoperative follow-up. Microscopic sections from resections were evaluated for the presence of CTE with standard stains and antibodies to tau (clone AT8)...

BACKGROUND: Hydatid disease is a worldwide zoonosis produced by the larval stage of cestodes of the Echinococcus genus. Hydatid disease primarily involves the liver and lungs. The brain is involved in less than 2% of cases. Surgery has long been the only choice for the treatment, but chemotherapy has been successfully replaced surgery in some special cases. CASE PRESENTATION: We report a rare hydatid disease case which presented with multiple lesions in right frontal lobe, an uncommon site, and in the liver and lungs...

Drug-induced peripheral neuropathy had been rarely reported as an adverse effect of some antiepileptic drugs (AEDs) at high cumulative doses or even within the therapeutic drug doses or levels. We describe clinical and diagnostic features of a patient with peripheral neuropathy as an adverse effect of chronic topiramate (TPM) therapy. A 37-year-old woman was presented for the control of active epilepsy (2010). She was resistant to some AEDs as mono- or combined therapies (carbamazepine, sodium valproate, levetiracetam, oxcarbazepine and lamotrigine)...

BACKGROUND: Thirty-percent of patients with epilepsy are drug-resistant, and might benefit from effective noninvasive therapeutic interventions. Evidence is accumulating on the efficacy of autonomic biofeedback therapy using galvanic skin response (GSR; an index of sympathetic arousal) in treating epileptic seizures. This study aimed to extend previous controlled clinical trials of autonomic biofeedback therapy with a larger homogeneous sample of patients with temporal lobe epilepsy. In addition, we used neuroimaging to characterize neural mechanisms of change in seizure frequency following the therapy...

Objective: To investigate the damage of gray matter structure in MRI-negative epilepsy patients with different symptoms by voxel-based morphometry (VBM). Methods: From June, 2009 to October, 2016, ninety MRI-negative epilepsy patients and thirty-five healthy volunteers underwent the 3T magnetic resonance imaging scan in Nanjing General Hospital. The patients were divided into three groups, including idiopathic generalized tonic-clonic seizure (I-GTCS), secondarily generalized tonic-clonic seizure (S-GTCS), and partial seizure (PS) according to different symptoms...

To evaluate metabolic changes in the ipsi- and contralateral hemisphere in children showing a cognitive profile consistent with early reorganization of cognitive function, we evaluated the regional glucose uptake, interhemispheric metabolic connectivity, and cognitive function in children with unilateral SWS. Interictal 2-deoxy-2[18 F]fluoro-D-glucose (FDG)-PET scans of 27 children with unilateral SWS and mild epilepsy and 27 age-matched control (non-SWS children with epilepsy and normal FDG-PET) were compared using statistical parametric mapping (SPM)...

A rosette-forming glioneuronal tumor (RGNT) was initially reported as an infratentorial tumor that comprised both small neurocytic rosettes and astrocytic components. However, a few studies have reported supratentorial RGNTs arising in the cerebral hemispheres. Here, we report an unusual case involving a 9-year-old boy with a supratentorial RGNT who presented with intractable epilepsy and behavioral changes. Brain MRI revealed a well-circumscribed space-occupying lesion with septae in the right inferomedial parietal lobe...

Occipital cortical malformation is a rare neurodevelopmental disorder characterized by pachygyria and polymicrogyria of the occipital lobes as well as global developmental delays and seizures. This condition is due to biallelic, loss-of-function mutations in LAMC3 and has been reported in four unrelated families to date. We report an individual with global delays, seizures, and polymicrogyria that extends beyond the occipital lobes and includes the frontal, parietal, temporal, and occipital lobes. Next-generation sequencing identified a homozygous nonsense mutation in LAMC3: c...

Multinodular and vacuolating neuronal tumors (MVNT) are low grade neuronal tumors classified in cerebral tumors based on 2016 WHO central nerve system classification. Previously, MVNTs were probably tumors incidentally determined by imaging methods, but they could not be diagnosed or they were misdiagnosed. Two cases are reported in the present study, for which radiological imaging was carried out for epilepsy in one and for headache in the other. The first case was a twenty seven years old female patient with headache complaint...

An 82-year-old man was admitted to the emergency department following bizarre behaviour. Police had noticed him driving erratically through his village. He did not stop when instructed, drove slowly home and appeared 'vacant' on questioning. While in hospital, he had approximately 15 episodes of catatonia, involving rigidity, negativism, mutism except echolalia and perseveration, automatic obedience and utilisation phenomena, lasting 2-20 min each. Between episodes, he was amnestic but otherwise well. Electroencephalography demonstrated bifrontal slowing with left-sided emphasis, and captured two focal onset partial seizures with the clinical correlate of the syndrome described above...

Gaucher's disease is a rare autosomal recessive, potentially fatal disorder but most common type among lysosomal storage disorders. The disease's incidence is around 1/40 000 to 1/60 000 births in the general population. A 32-year-old man, born out of non-consanguineous union, presented with generalised tonic-clonic seizures and myoclonus since 17 years of age. Seizures were noted to be resistant to multiple epileptic drugs. He developed gait imbalance, intentional tremor and dysarthria. Detailed examination revealed hepatosplenomegaly, bilateral pancerebellar signs with normal power, reflexes and sensory system...

PURPOSE: Magnetoencephalography (MEG) was used to record and localize the sources of the epileptiform discharges, in absence epilepsy, at three different time intervals to infer the sources of involvement during generation and propagation. METHODS: Twenty patients with absence epilepsy (M:F=1:1; age: 10.2±3.4years), which included 12 patients with childhood absence epilepsy (CAE) and 8 patients with juvenile absence epilepsy (JAE), were recruited in this prospective MEG based study...

Women show better performance than men on a range of episodic memory tasks. Evidence regarding a neuroanatomical localization of this effect remains ambiguous. It has been suggested that anterior temporal lobe structures are responsible for sex differences in verbal memory, yet temporal lobe epilepsy (TLE) and TLE surgery do not affect women's verbal memory advantage. Instead, frontal lobe regions may be relevant for female verbal memory superiority, i.e. by enabling more efficient encoding and retrieval strategies in women...

Refractory frontal lobe epilepsy has been traditionally treated through a frontal lobectomy. A disconnective technique may allow similar seizure outcomes while avoiding the complications associated with large brain resections. The aim of this study was to describe a new technique of selective disconnection of the frontal lobe that can be performed in cases of refractory epilepsy due to epileptogenic foci involving 1 frontal lobe (anterior to the motor cortex), with preservation of motor function. In addition to the description of the technique, an illustrative case is also presented...

In this review, the authors discuss the problem of management of the patient with epilepsy with regard an impact of epileptic seizures and syndromes on sleep structure. Sleep disorders can lead to worsening of seizure control and general medical condition of the patients. However, seizures themselves and types of epilepsy can affect the sleep architecture. One of the most frequent symptoms of disordered sleep in epilepsy patients is excessive daytime sleepiness, which can be a consequence of poor sleep quality due to frequent nocturnal seizures or excessive interictal epileptiform activity during sleep leading to frequent arousals...

We report a case of impairment of consciousness (IOC) induced by electrical cortical stimulation (ECS) of homologous regions within the lateral frontal convexities in a patient with medically intractable epilepsy. The patient had mixed features of idiopathic generalized and focal epilepsy. On intracranial EEG recording, interictal and ictal discharges showed a high degree of synchrony across widespread bilateral fronto-parietal areas. We identified regions in the lateral frontal lobes that reliably and produced loss of consciousness by ECS...
