While brain tumors are a frequent cause of seizures, they rarely cause epileptic spasms (ES). The objective of this study was to investigate features of tumor-associated ES. We conducted a retrospective review of patients with ES and a brain tumor. Demographics; pathologic, radiologic, and EEG data; treatment response; and long-term outcome were collected. Twenty four patients were identified; 11 met inclusion criteria. Epileptic spasm (ES) onset occurred prior to tumor diagnosis in seven patients (63%), and after tumor resection in 4 patients (36%)...

INTRODUCTION: Despite decades of research into the prognostic significance of post anoxic myoclonic status (MS), no consistent definition has been used to describe its clinical appearance. We set out to characterize the clinical features of MS and hypothesized that there are distinct clinical subtypes that may have prognostic implications. METHODS: Video EEG reports from 2008 to 2016 were searched to identify adult patients with post anoxic MS defined as persistent myoclonus for >30minutes beginning within 3days of cardiac arrest in a comatose patient...

PURPOSE OF REVIEW: In this review, we elucidate the evaluation process involved in the diagnosis of psychogenic non-epileptic seizures (PNES). Minimum clinical criteria required to attain this diagnosis via a staged approach are delineated. The psychological underpinnings and management of PNES from the neurologists' perspective are also explored. RECENT FINDINGS: Helpful clues can be deduced from history-taking, seizure semiology, ictal/peri-ictal physical exam, and ictal/inter-ictal EEG data...

BACKGROUND: Musicogenic reflex seizures (MRS) are a rare form of seizures described in patients with temporal lobe epilepsy (TLE), mainly of unknown etiology. Epilepsy with antibodies against glutamic acid decarboxylase (GAD-ab) is a form of autoimmune epilepsy for which no specific semiology has been described. AIM OF THE STUDY: To retrospectively review the incidence of MRS in the general epileptic population and in the series of patients with epilepsy and GAD-ab and to describe its clinical and paraclinical characteristics...

To evaluate the sensitivity and specificity of quantitative EEG (QEEG) spectrograms in order to distinguish epileptic from non-epileptic events. Seventeen patients with paroxysmal non-epileptic events, captured during EEG monitoring, were retrospectively assessed using QEEG spectrograms. These patients were compared to a control group of 13 consecutive patients (ages 25-60 years) with epileptic seizures of similar semiology. Assessment of raw EEG was employed as the gold standard against which epileptic and non-epileptic events were validated...

INTRODUCTION: Refractory epilepsy is a common clinical manifestation in patients with tuberous sclerosis complex (TSC), which can be complicated by many life-threatening conditions, such as status epilepticus (SE). However, very few reports mention the patterns and semiology of SE in those patients. OBJECTIVE: To study the clinical characteristics and outcomes of SE in TSC patients. MATERIALS AND METHODS: This observational, prospective study was carried out on 36 Egyptian children with definite TSC...

This retrospective cohort study included 53 patients admitted in ICU, of average age 69 years, without neurologic disorder before initiation of piperacillin continuous infusion at standard dose and who underwent piperacillin serum concentration monitoring. Among them, 23 developed neurologic disorder for which the piperacillin causality was chronologically and semiologically suggestive. A concentration threshold of 157.2 mg/L independently predicted neurotoxicity with 96.7% specificity and 52.2% sensitivity and may constitute a limitation when targeting less susceptible pathogens...

O Walusinski
Joseph Jumentié (1879-1928), through his clinical skill and expertise in anatomical pathology, enhanced the prestige of the master neurologists he studied under- Jules Dejerine, Augusta Dejerine-Klumpke and Joseph Babiński -and their fame overshadowed the crucial support that Jumentié provided them. Following a remarkable doctoral thesis in 1911, which defined the semiology of tumors in the cerebellopontine angle, Jumentié conducted research into various areas of neurology and authored numerous publications...

PURPOSE: Convulsive epileptic seizures triggered by transient cerebral hypoperfusion 'reflex anoxic seizures' are well-described in children but are not commonly recognized in adults. METHODS: We report a case series of 12 adults who presented acutely after generalized tonic-clonic seizures with a clear syncopal phase before the convulsion. We describe the aetiology, semiology and natural history of these events. RESULTS: Four patients (33...

In this review, authors discuss the semiology and noninvasive investigations of insular epilepsy, an underrecognized type of epilepsy, which may mimic other focal epilepsies. In line with the various functions of the insula and its widespread network of connections, insular epilepsy may feature a variety of early ictal manifestations from somatosensory, visceral, olfactory, gustatory, or vestibular manifestations. Depending on propagation pathways, insular seizures may also include altered consciousness, dystonic posturing, complex motor behaviors, and even autonomic features...

INTRODUCTION: Stereotactic stimulations of the insular cortex through intracranial electrodes aim at characterizing the semiology of insular seizures. These stimulations, carried out in the context of Stereo-Electro-Encephalography (SEEG) during presurgical monitoring of epilepsy, reproduce the ictal symptoms observed during the development of insular seizures. METHODS: The authors reviewed the results of insular stimulations performed in 222 patients admitted between 1997 and 2015 for presurgical SEEG exploration of atypical temporal or perisylvian epilepsy...

OBJECTIVE: To report the presurgical workup, surgical procedures, and outcomes in a series of pediatric patients with drug-resistant epilepsy involving the perisylvian/insular regions. METHODS: We retrospectively assessed 16 pediatric patients affected by drug-resistant focal epilepsy involving perisylvian/insular regions, who consecutively underwent tailored resective surgery. All patients underwent a detailed presurgical workup, which included the analysis of the anatomoelectroclinical correlations with scalp electroencephalography (EEG) and/or with stereo-electroencephalography (SEEG), brain magnetic resonance imaging (MRI), and comprehensive cognitive and neuropsychological evaluations...

Koji Iida, Hiroshi Otsubo
Stereoelectroencephalography (SEEG) is a method for invasive study of patients with refractory epilepsy. Localization of the epileptogenic zone in SEEG relied on the hypothesis of anatomo-electro-clinical analysis limited by X-ray, analog electroencephalography (EEG), and seizure semiology in the 1950s. Modern neuroimaging studies and digital video-EEG have developed the hypothesis aiming at more precise localization of the epileptic network. Certain clinical scenarios favor SEEG over subdural EEG (SDEEG). SEEG can cover extensive areas of bilateral hemispheres with highly accurate sampling from sulcal areas and deep brain structures...

The risk of unprovoked seizures in population-based cohorts of cerebral infection survivors is 7-8% in developed countries, rising to considerably higher rates in resource-poor countries. The main risk factors for epilepsy after cerebral infection, besides acute seizures, are infection-associated brain lesions and status epilepticus during the acute phase. Despite the high prevalence of pharmacoresistant epilepsies after cerebral infections, especially in patients with MRI-identifiable lesions, only a small minority undergoes epilepsy surgery...

Schizophrenia is a complex pathology. Its prevalence reaches almost 1 %. Its semiology can be diversified. Sensorial perception can be altered included pain perception. Most of the studies conclude that psychotic patients have a hypoalgesia. It's important to consider this fact to avoid missing potentially grave somatic disease.

The pre-operative assessment and surgical management of patients with dual pathology is challenging. We describe a patient with drug-resistant focal epilepsy with hippocampal sclerosis and extensive periventricular nodular heterotopia in the same hemisphere. The semiology, scalp EEG, and imaging were divergent, but the presence of focal interictal and ictal epileptic discharges of the putative ictal onset zone resulted in successful localization of the epileptogenic zone. A less aggressive resection was performed based on intracranial EEG recording...

OBJECTIVE: To clarify the semiology of febrile seizures (FS) and to determine the frequency of FS with symptoms suggestive of focal onset. METHODS: FS symptoms in children were reported within 24h of seizure onset by the parents using a structured questionnaire consisting principally of closed-ended questions. We focused on events at seizure commencement, including changes in behavior and facial expression, and ocular and oral symptoms. We also investigated the autonomic and motor symptoms developing during seizures...
