Adjunctive cenobamate in people with focal onset seizures: Insights from the Italian Expanded Access Program.

OBJECTIVE: This study was undertaken to assess the effectiveness/tolerability of adjunctive cenobamate, variations in the load of concomitant antiseizure medications (ASMs) and predictors of clinical response in people with focal epilepsy. METHODS: This was a retrospective study at 21 centers participating in the Italian Expanded Access Program. Effectiveness outcomes included retention and responder rates (≥50% and 100% reduction in baseline seizure frequency). Tolerability/safety outcomes included the rate of treatment discontinuation due to adverse events (AEs) and their incidence. Total drug load was quantified as the number of concomitant ASMs and total defined daily dose (DDD). Concomitant ASMs were also classified according to their mechanism of action and pharmacokinetic interactions to perform explorative subgroup analyses. RESULTS: A total of 236 subjects with a median age of 38 (Q1-Q3 = 27-49) years were included. At 12 months, cenobamate retention rate was 78.8% and responders were 57.5%. The seizure freedom rates during the preceding 3 months were 9.8%, 12.2%, 16.3%, and 14.0% at 3, 6, 9, and 12 months. A higher percentage of responders was observed among subjects treated with clobazam, although the difference was not statistically significant. A total of 223 AEs were recorded in 133 of 236 participants, leading to cenobamate discontinuation in 8.5% cases. At 12 months, a reduction of one or two concomitant ASMs occurred in 42.6% and 4.3% of the subjects. The median total DDD of all concomitant ASMs decreased from 3.34 (Q1-Q3 = 2.50-4.47) at baseline to 2.50 (Q1-Q3 = 1.67-3.50) at 12 months (p < .001, median percentage reduction = 22.2%). The highest rates of cotreatment withdrawal and reductions in the DDD were observed for sodium channel blockers and γ-aminobutyric acidergic modulators (above all for those linked to pharmacokinetic interactions), and perampanel. SIGNIFICANCE: Adjunctive cenobamate was associated with a reduction in seizure frequency and in the burden of concomitant ASMs in adults with difficult-to-treat focal epilepsy. The type of ASM associated did not influence effectiveness except for a favorable trend with clobazam.

FDG-PET and ASL MRI identify largely overlapping hypermetabolic and hyperperfusion changes in limbic autoimmune encephalitis.

BACKGROUND: Arterial spin labeling (ASL) MRI has been anecdotally used to assess brain perfusion in autoimmune encephalitis (AE) and its relationship with [18F]FDG-PET dysmetabolism has been scarcely investigated.Considering the physiological coupling of metabolism and perfusion, we aimed to evaluate the degree of correspondence between ASL-MRI and [18F]FDG-PET in AE. METHODS: A retrospective cohort of five patients underwent ASL-MRI and [18F]FDG-PET during the acute stage and at follow-up. We assessed the presence of regions with hypermetabolism on [18F]FDG-PET and hyperperfusion on ASL-MRI and evaluated concordance and spatial overlap of these metrics. Clinical assessment scale in AE and modified Rankin Scale were obtained at baseline and follow-up. RESULTS: In two patients [18F]FDG-PET and ASL-MRI were unremarkable; in three patients there were anatomically overlapping areas of hypermetabolism and hyperperfusion (average DICE similarity coefficient 0.358). Following immunotherapy, metabolic and perfusion changes consistently demonstrated a progressive normalization, aligning with clinical improvement. CONCLUSIONS: We identified suboptimal anatomical correspondence of abnormalities assessed with [18F]FDG-PET and ASL-MRI. Hyperperfusion and hypermetabolism might reflect differently AE-related pathophysiological correlates, but they both demonstrate ability to monitor disease activity. ASL-MRI is a promising marker of disease activity in AE and a favorable alternative to [18F]FDG-PET due to its cost-effectiveness, safety, and wide availability.

Pitfalls and unmet needs of transition in epilepsy: Understanding the adult neurologist perspective.

Transition from the paediatric holistic approach to the adult more individual care of epilepsy is a process that carries a high level of complexity and involves many actors. It is a mandatory step so to provide a gold-standard quality of care in young people with epilepsy. Its failure is strongly associated with a poor epilepsy, cognitive, and behavioural outcome. Although the interest of the scientific community on transition has increased, in the clinical practice it is still considered a sensitive issue, in particular for adult neurologists. In this study we aimed at exploring pitfalls and unmet needs of transition from the adult neurologists' perspective. A short survey, aimed to adult neurologists, was designed to explore i) whether transition is considered a problematic issue for the adult neurologist, ii) how transition impact his/her clinical practice, iii) which are the major problems related to the process, and iv) how transition may be improved. The results of the survey showed that transition is felt as a complex process that needs a shared action plan between child and adult neurologists, possibly with multidisciplinary team meetings as well as a higher training on childhood epilepsies for the adult neurologist.

The role of EEG and neuroimaging in the diagnosis of non-convulsive status epilepticus in Subacute Encephalopathy with Seizures in Alcoholics (SESA syndrome): a case report and overview of the literature.

Epileptic seizures are frequently associated with liver dysfunction and alcoholism. Subacute encephalopathy with seizures in chronic alcoholics (SESA) is an underrecognized condition with peculiar clinical, EEG and neuroradiological features.We report the case of a 58-year-old man with previous alcohol use disorder (AUD) and acute-on chronic liver failure on alcohol-related cirrhosis, referred for urgent Orthotopic Liver Transplantation evaluation. The patient presented with delirium, aphasia and progressive deterioration of consciousness leading to intensive care unit admission. EEG showed slow activity with superimposed lateralized periodic discharges (LPDs) over the left temporo-occipital regions and ictal discharges with focal motor phenomena, consistent with focal status epilepticus. Antiseizure treatment with lacosamide and levetiracetam was administered with progressive improvement of consciousness.Brain MRI disclosed T2/FLAIR areas of hyperintensity in the left pulvinar and T2/FLAIR hyperintensity with corresponding DWI hyperintensity in the left hippocampal cortex, suggestive of post/peri-ictal excitotoxic changes with anatomical correspondence to focal LPDs distribution. SWI demonstrated decreased prominence of cortical veins in the left temporo-occipital region consistent with increased venous blood oxygenation in compensatory hyperperfusion.In conclusion, SESA should be suspected in the differential diagnosis of patients with AUD presenting with focal neurological deficits, seizures and focal EEG abnormalities. In this context, EEG and brain MRI represent useful tools with both diagnostic and prognostic value.

CO2 is the contrast media to choose in patients with initial Chronic Kidney Disease undergoing endovascular aneurysm repair to prevent further renal function deterioration.

OBJECTIVE: Even low quantities of iodine contrast media (ICM) could be responsible for exacerbation of a chronic kidney disease (CKD). Aim of this study was to determine whether it is more reasonable to perform endovascular aneurysm repair (EVAR) procedures in patients with initial CKD using CO2 rather than ICM to prevent further kidney deterioration. METHODS: A retrospective analysis was performed at our institution to identify patients with preoperative CKD at initial stage (class G3a-G3b according to KDOQI-KDIGO classification) who underwent either CO2-EVAR or ICM-EVAR. Primary endpoint was renal function evaluation; secondary endpoints were technical success, perioperative complications, hospital stay, and reinterventions and overall mortality at follow-up. RESULTS: Both CO2-EVAR and ICM-EVAR groups were composed of 21 patients. There were no differences in demographics, anatomy, and comorbidities, apart from worse ASA score in CO2-EVAR group (100% vs 57.1%, p = .001). Preoperative serum creatinine and glomerular filtration rates (GFR) were comparable (1.73 vs 1.6 mg/dl, p = .082 and 39.71 vs 43.04 mL/min/1.73 m2, p = .935). At follow-up (16.7 ± 18.1 months), CO2-EVAR was not associated with significant changes in creatinine and GFR, whereas ICM-EVAR determined a significant increase in creatinine (1.6 mg/dl vs 1.91 mg/dl, p = .04) and decrease in GFR values (43 vs 37.9 mL/min/1.73 m2, p = .04), determining the need for dialysis in one patient. CONCLUSIONS: ICM seems to be a determining factor in worsening renal function; therefore, an effort should be made to standardize the use of CO2 as the contrast medium of choice in patients with initial renal insufficiency undergoing EVAR.

High-resolution ultrasound and superb microvascular imaging findings in a case of post-COVID-19 vaccine parsonage-turner syndrome with multiple nerves involvement.

Parsonage-Turner syndrome (PTS) is an idiopathic condition that may be triggered by vaccination against SARS-CoV-2. High-resolution ultrasound can support the diagnosis and monitoring of PTS patients by demonstrating specific nerve abnormalities. The recently implemented superb microvascular imaging technology can help stratify the prognosis of these patients, with the potential to contribute to the clinical management of PTS.

Long-term effectiveness of add-on perampanel in patients with Lennox-Gastaut syndrome: A multicenter retrospective study.

This retrospective study assessed long-term effectiveness of add-on perampanel (PER) in patients with Lennox-Gastaut syndrome (LGS). Outcomes included time to PER failure and time to seizure relapse in responders. PER failure was defined as either discontinuation of PER or initiation of another treatment. Seizure relapse in responders was defined as occurrence of a seizure in seizure-free patients and increase of at least 50% in average monthly seizure frequency for those who were responders. Eighty-seven patients were included. Treatment failure occurred in 52 (59.8%) subjects at a median time of 12 months. Treatment failure was due to lack of efficacy in 27 (52.0%) patients, lack of tolerability in 14 (27.0%), and both reasons in 11 (21.0%). A slower titration was associated with a lower risk of PER failure compared to faster titration schedules, and the occurrence of adverse events increased the risk of treatment failure. Thirty-six patients (41.4%) were responders during a median follow-up of 11 months. Seizure relapse occurred in 13 of 36 (36.1%) patients after a median time of 21 months. The overall rate of seizure responders was 23 of 87 (26.4%) at the end of follow-up. This study provides real-world evidence on the effectiveness of PER as adjunctive treatment in LGS patients.

Distinctive electro-clinical, neuroimaging and histopathological features of temporal encephaloceles associated to epilepsy.

OBJECTIVE: Encephaloceles (ENCs) may cause clinical complications, including drug-resistant epilepsy that can be cured with epilepsy surgery. METHODS: We describe clinical, diagnostic, and neuropathological findings of 12 patients with temporal ENC and epilepsy evaluated for surgery and compare them with a control group of 26 temporal lobe epilepsy (TLE) patients. RESULTS: Six patients had unilateral and 6 bilateral temporal ENCs. Compared to TLEs, ENCs showed i) later epilepsy onset, ii) higher prevalence of psychiatric comorbidities, iii) no history of febrile convulsions, and iv) ictal semiology differences. Seven patients had MRI signs of gliosis, and 9 of intracranial hypertension. Interictal EEG analysis in ENCs demonstrated significant differences with controls: prominent activity in the beta/gamma frequency bands in frontal regions, interictal short sequences of low-voltage fast activity, and less frequent and more localized interictal epileptiform discharges. Ictal EEG patterns analyzed in 9 ENCs showed delayed and slower contralateral spread compared to TLEs. All ENCs that underwent surgery (7 lobectomies and 1 lesionectomy) are in Engel class I. Neuropathological examination revealed 4 patterns: herniated brain fragments, focal layer I distortion, white matter septa extending into the cortex, and altered gyral profile. CONCLUSIONS AND SIGNIFICANCE: The described peculiarities might help clinicians to suspect the presence of largely underdiagnosed ENCs.

Epileptic phenotypes in autoimmune encephalitis: from acute symptomatic seizures to autoimmune-associated epilepsy.

OBJECTIVE: To describe the clinical and paraclinical findings, treatment options and long-term outcomes in autoimmune encephalitis (AE), with a close look to epilepsy. METHODS: In this retrospective observational cohort study, we enrolled patients with new-onset seizures in the context of AE. We compared clinical and paraclinical findings in patients with and without evidence of antibodies. RESULTS: Overall, 263 patients (138 females; median age 55 years, range 4-86) were followed up for a median time of 30 months (range 12-120). Antineuronal antibodies were detected in 63.50%.Antibody-positive patients had multiple seizure types (p=0.01) and prevalent involvement of temporal regions (p=0.02). A higher prevalence of episodes of SE was found in the antibody-negative group (p<0.001).Immunotherapy was prescribed in 88.60%, and effective in 61.80%. Independent predictors of favourable outcome of the AE were early immunotherapy (p<0.001) and the detection of antineuronal surface antibodies (p=0.01).Autoimmune-associated epilepsy was the long-term sequela in 43.73%, associated with cognitive and psychiatric disturbances in 81.73%. Independent predictors of developing epilepsy were difficult to treat seizures at onset (p=0.04), a high number of antiseizure medications (p<0.001), persisting interictal epileptiform discharges at follow-up (p<0.001) and poor response to immunotherapy during the acute phase (p<0.001). CONCLUSIONS: The recognition of seizures secondary to AE represents a rare chance for aetiology-driven seizures management. Early recognition and treatment at the pathogenic level may reduce the risk of long-term irreversible sequelae. However, the severity of seizures at onset is the major risk factor for the development of chronic epilepsy.This study provides class IV evidence for management recommendations.

Relative importance of clinical outcomes and safety risks of antiseizure medication monotherapy for patients and physicians: Discrete choice experiment eliciting preferences in real-world study "VOTE".

OBJECTIVE: This study was undertaken to elicit patients' preferences for attributes characterizing antiseizure medication (ASM) monotherapy options before treatment consultation, and to explore the trade-offs patients consider between treatment efficacy and risks of side effects. Further objectives were to explore how treatment consultation may affect patient preferences, to elicit physicians' preferences in selecting treatment, and to compare patient and physician preferences for treatment. METHODS: This prospective, observational study (EP0076; VOTE) included adults with focal seizures requiring a change in their ASM monotherapy. Patients completed a discrete choice experiment (DCE) survey before and after treatment consultation. Physicians completed a similar survey after the consultation. The DCE comprised 12 choices between two hypothetical treatments defined by seven attributes. The conditional relative importance of each attribute was calculated. RESULTS: Three hundred ten patients (mean [SD] age = 46.8 [18.3] years, 52.3% female) were enrolled from eight European countries, of whom 305 completed the survey before consultation and 273 completed the survey before and after consultation. Overall, this preference study in patients who intended to receive a new ASM monotherapy suggests that patient preferences were ordered as expected, with better outcomes being preferred to worse outcomes; patients preferred a higher chance of seizure freedom, lower risk of developing clinical depression, and fewer severe adverse events; avoiding moderate-to-severe "trouble thinking clearly" was more important than avoiding any other side effect. There were qualitative differences in what patients and physicians considered to be the most important aspects of treatment for patients; compared with patients, physicians had a qualitatively stronger preference for greater chance of seizure freedom and avoiding personality changes. Patients' preference weights were qualitatively similar before and after treatment consultation. SIGNIFICANCE: For patients, seizure freedom and avoiding trouble thinking clearly were the most important treatment attributes. Physicians and patients may differ in the emphasis they place on specific attributes.

The value of EEG attenuation in the prediction of outcome in COVID-19 patients.

INTRODUCTION: During the COVID-19 pandemic, electroencephalography (EEG) proved to be a useful tool to demonstrate brain involvement. Many studies reported non-reactive generalized slowing as the most frequent pattern and epileptiform activity in a minority of patients. OBJECTIVE: To investigate the prevalence of diffuse unreactive background attenuation or suppression and its correlation with outcome in a cohort of COVID-19 patients. METHODS: The EEGs recorded during the first year of the COVID-19 pandemic were retrospectively evaluated to identify the main pattern and focus on the occurrence of a low-voltage background, either attenuated (10-20 µV) or suppressed (< 10 µV). We sought a correlation between in-hospital mortality and low-voltage EEG. In a subsample of patients, biomarkers of inflammation, hypoxemia and organ failure were collected. Brain imaging was also evaluated. RESULTS: Among 98 EEG performed in 50 consecutive patients, diffuse unreactive slowing was the most prevalent pattern (54%), followed by unreactive attenuation or suppression pattern (26%), being the latter significantly correlated with an unfavourable outcome (p = 0.0004). Survivors showed significantly lower interleukine-6 values compared to non-survivors. Patients with attenuated EEG and non-survivors also showed lower PaO2/FiO2 values. Neuroradiological findings were very heterogeneous with a prevalence of lesions suggestive of a microangiopathic substrate. CONCLUSIONS: EEG attenuation or suppression may be more frequent than previously reported and significantly associated with a poor outcome. SARS-CoV-2 infection may result in encephalopathy and reduced EEG voltage through mechanisms that are still unknown but deserve attention given its negative impact on prognosis.

Knowledge and attitudes of neurologists toward epilepsy surgery: an Italian survey.

The current study, conceived with the contribution of the Commission for Epilepsy Surgery of the Italian League Against Epilepsy (LICE) and the Epilepsy Study Group of the Italian Neurological Society (SIN), aimed to assess potential physician-related barriers to refer subjects for epilepsy surgery. All the members of SIN and LICE were invited by email to complete a 28-item online questionnaire. The survey items included: (1) individual and medical practice characteristics, (2) knowledge of current indications to select candidates for epilepsy surgery, (3) factors potentially affecting the attitude toward epilepsy surgery. Overall, 210 physicians completed the survey. More than half (63.3%) of the participants showed proper knowledge of the ILAE drug-resistance. Definition and almost two-thirds of them (71.9%) considered themselves adequately informed about indications, risks, and benefits of epilepsy surgery. Surgery was regarded as a valid option to be used as early as possible by 84.8% of the interviewees, and 71% of them estimated its complication rate to be low. However, more than half (63%) of the respondents reportedly referred patients for surgery only after the failure of 3-5 antiseizure medications. Overestimation of risks/complications of surgery and inadequate healthcare resources were identified as the main factor contrasting the patient referral for surgery by 43% and 40.5% of the participants, respectively. In conclusion, this survey confirms the existence of knowledge gap within both physicians and the healthcare system, as well as an educational need regarding epilepsy surgery. Further researches are warranted to define learning outcomes and optimize educational tools.

Temporal lobe epilepsy surgery in children and adults: A multicenter study.

OBJECTIVE: To assess seizure and cognitive outcomes and their predictors in children (<16 years at surgery) and adults undergoing temporal lobe epilepsy (TLE) surgery in eight Italian centers. METHODS: This is a retrospective multicenter study. We performed a descriptive analysis and subsequently carried out multivariable mixed-effect models corrected for multiple comparisons. RESULTS: We analyzed data from 511 patients (114 children) and observed significant differences in several clinical features between adults and children. The possibility of achieving Engel class IA outcome and discontinuing antiepileptic drugs (AEDs) at last follow-up (FU) was significantly higher in children (P = .006 and < .0001). However, percentages of children and adults in Engel class I at last FU (mean ± SD, 45.9 ± 17 months in children; 45.9 ± 20.6 months in adults) did not differ significantly. We identified different predictors of seizure outcome in children vs adults and at short- vs long-term FU. The only variables consistently associated with class I outcome over time were postoperative electroencephalography (EEG) in adults (abnormal, improved,odds ratio [OR] = 0.414, P = .023, Q = 0.046 vs normal, at 2-year FU and abnormal, improved, OR = 0.301, P = .001, Q = 0.002 vs normal, at last FU) and the completeness of resection of temporal magnetic resonance (MR) abnormalities other than hippocampal sclerosis in children (OR = 7.93, P = .001, Q = 0.003, at 2-year FU and OR = 45.03, P < .0001, Q < 0.0001, at last FU). Cognitive outcome was best predicted by preoperative performances in either age group. SIGNIFICANCE: Clinical differences between adult and pediatric patients undergoing TLE surgery are reflected in differences in long-term outcomes and predictors of failures. Children are more likely to achieve sustained seizure freedom and withdraw AEDs after TLE surgery. Earlier referral should be encouraged as it can improve surgical outcome.

Hybrid Surgical Approach to a Giant Post-Coarctation Aortic Aneurysm.

PURPOSE: To report a rare case of giant aortic coarctation (CoA)-related descending thoracic aneurysmal degeneration, complicated by an acute aortic dissection. CASE REPORT: A 57-year-old man referred with acute chest pain to the emergency department. A computed tomography angiography (CTA) revealed a CoA with a giant post-stenotic descending thoracic aneurysm (14 cm) and a concomitant left subclavian artery (LSA) aneurysm, complicated by an acute type B aortic dissection. A single-stage hybrid procedure was planned in an urgent setting. Initially, a left common carotid-to-left subclavian artery (LCCA-LSA) bypass was performed to gain a suitable proximal landing zone, the procedure was then completed with 3 thoracic endografts and 1 aortic dissection stent through a percutaneous femoral approach. The patient was discharged in postoperative day 8th without complications; the CTA performed at 1 month demonstrated patency of supra-aortic and visceral vessels, dilation of CoA site and exclusion of the false lumen. CONCLUSIONS: CoA is a congenital malformation rarely found in adults that may represent a challenge for the surgeon, especially when combined with a complication like an acute aortic dissection. This case shows that a hybrid approach is a safe and feasible treatment option even in such complex anatomies.

Predictors of self-perceived health worsening over COVID-19 emergency in ALS.

INTRODUCTION: Factors influencing self-perceived health status over Corona Virus Disease 2019 (COVID-19) emergency in vulnerable populations, such as patients with chronic neurological diseases, are still unknown. In this work, we aimed at testing whether clinical care changes imposed by the quarantine, together with certain demographic and disease-specific features, might have determined a self-perceived worsening of health status in patients with amyotrophic lateral sclerosis (ALS). METHODS: A brief web-based questionnaire investigating self-perceived anxiety, depression, and motor worsening, as well as clinical care changes over COVID-19 emergency, was administered to ALS patients currently followed at San Martino Hospital. Ordinal and logistic regression analyses were applied to identify significant predictors of health status. RESULTS: Fifty-seven ALS patients completed the questionnaire. A total of 35.08% of cases reported anxiety symptoms, 36.84% depressive symptoms, and 35.08% reported worsening of motor symptoms. Significant predictors of anxiety symptoms severity included female gender, greater motor impairment, more aggressive disease course, and rehabilitation therapy suspension. The only significant predictor of depressive symptoms severity was a more aggressive disease course. Significant predictors of motor worsening were shorter disease duration and exams/visits cancelation. DISCUSSION: COVID-19 emergency and its management exerted a significant impact on self-perceived health status in patients with ALS, particularly in those cases in the earliest disease phases and with a more aggressive disease course. These findings have potential to improve personalized medicine strategies in the next phase.

The surgical treatment of epilepsy.

In 2009, the Commission for Epilepsy Surgery of the Italian League Against Epilepsy (LICE) conducted an overview about the techniques used for the pre-surgical evaluation and the surgical treatment of epilepsies. The recognition that, in selected cases, surgery can be considered the first-line approach, suggested that the experience gained by the main Italian referral centers should be pooled in order to provide a handy source of reference. In light of the progress made over these past years, some parts of that first report have accordingly been updated. The present revision aims to harmonize the general principles regulating the patient selection and the pre-surgical work-up, as well as to expand the use of epilepsy surgery, that still represents an underutilized resource, regrettably. The objective of this contribution is drawing up a methodological framework within which to integrate the experiences of each group in this complex and dynamic sector of the neurosciences.

Quality of life, psychiatric symptoms, and stigma perception in three groups of persons with epilepsy.

OBJECTIVE: The current study aimed to describe quality of life (QoL) levels, psychiatric symptoms prevalence, and perceived stigma levels in persons with either drug-resistant epilepsy (DRE) or drug-sensitive epilepsy (DSE) and in persons with epilepsy (PwE) with DRE that underwent epilepsy surgery (DREES). METHODS: Persons with epilepsy diagnosed as having DRE according to International League Against Epilepsy (ILAE) criteria, DSE, and DREES were enrolled at the Epilepsy Unit of the Neurological Institute Carlo Besta of Milan. Sociodemographic and clinical data, Quality of Life in Epilepsy Inventory (QOLIE-31), Symptom Checklist-90 (SCL-90), and the Epilepsy Stigma Scale (ESS) were collected based on self-reported information and on medical records. RESULTS: Sociodemographic, medical, and psychological data were obtained from 181 PwE: 80 with DRE, 31 with DSE, and 70 with DREES. We found that QoL is higher and psychiatric symptoms are lower in persons with DSE compared with DRE and that patients with DREES, who were drug-resistant before surgery, are in between DSE and DRE for both measures. Perceived stigma level is different in DSE and in DRE, that report the highest levels of stigma, and is between the other two groups in DREES. SIGNIFICANCE: This study suggests that low QoL levels and high psychiatric symptoms prevalence in drug-resistant PwE may be significantly improved after epilepsy surgery and suggests the importance of a biopsychosocial approach when planning therapeutic intervention.

Epilepsy course during COVID-19 pandemic in three Italian epilepsy centers.

During epidemic outbreaks, epilepsy course can be modified by different physical and psychological stressors and, most importantly, by irregular therapy intake. The effect of COVID-19 and quarantine isolation on the course of epilepsy and on incidence of new-onset seizures is still unclear. With the aim of managing epilepsy in quarantined patients, three Italian Epilepsy Centers set up telephone consultations using a semistructured interview, allowing a prospective collection of data on seizure course and other seizure-related problems during pandemic. The collected data on seizure course were compared with the analogous period of 2019. The level of patients' concern relating to the COVID-19 pandemic was also assessed using a numeric rating scale. To address the effect of COVID-19 pandemic on seizure incidence, data collection included the number of consultations for first seizures, relapse seizures, and status epilepticus (SE) in the emergency department of one of the participating centers. Clinical telephone interviews suggest the absence of quarantine effect on epilepsy course in our cohort. No differences in incidence of emergency consultations for seizures over a two-month period were also observed compared with a control period. As demonstrated in other infective outbreaks, good antiepileptic drug (AED) supplying, precise information, and reassurance are the most important factors in chronic conditions to minimize psychological and physical stress, and to avoid unplanned treatment interruptions.

A European questionnaire survey on epilepsy monitoring units' current practice for postoperative psychogenic nonepileptic seizures' detection.

BACKGROUND: In cases undergoing epilepsy surgery, postoperative psychogenic nonepileptic seizures (PNES) may be underdiagnosed complicating the assessment of postsurgical seizures' outcome and the clinical management. We conducted a survey to investigate the current practices in the European epilepsy monitoring units (EMUs) and the data that EMUs could provide to retrospectively detect cases with postoperative PNES and to assess the feasibility of a subsequent postoperative PNES research project for cases with postoperative PNES. METHODS: We developed and distributed a questionnaire survey to 57 EMUs. Questions addressed the number of patients undergoing epilepsy surgery, the performance of systematic preoperative and postoperative psychiatric evaluation, the recording of sexual or other abuse, the follow-up period of patients undergoing epilepsy surgery, the performance of video-electroencephalogram (EEG) and postoperative psychiatric assessment in suspected postoperative cases with PNES, the existence of electronic databases to allow extraction of cases with postoperative PNES, the data that these bases could provide, and EMUs' interest to participate in a retrospective postoperative PNES project. RESULTS: Twenty EMUs completed the questionnaire sheet. The number of patients operated every year/per center is 26.7 ( ±â€¯19.1), and systematic preoperative and postoperative psychiatric evaluation is performed in 75% and 50% of the EMUs accordingly. Sexual or other abuse is systematically recorded in one-third of the centers, and the mean follow-up period after epilepsy surgery is 10.5 ±â€¯7.5 years. In suspected postoperative PNES, video-EEG is performed in 85% and psychiatric assessment in 95% of the centers. An electronic database to allow extraction of patients with PNES after epilepsy surgery is used in 75% of the EMUs, and all EMUs that sent the sheet completed expressed their interest to participate in a retrospective postoperative PNES project. CONCLUSION: Postoperative PNES is an underestimated and not well-studied entity. This is a European survey to assess the type of data that the EMUs surgical cohorts could provide to retrospectively detect postoperative PNES. In cases with suspected PNES, most EMUs perform video-EEG and psychiatric assessment, and most EMUs use an electronic database to allow extraction of patients developing PNES.

Brain microvascular occlusive disorder in COVID-19: a case report.

We describe the case of a COVID-19 patient with severely impaired consciousness after sedation hold, showing magnetic resonance imaging (MRI) findings of (i) acute bilateral supratentorial ischemic lesions involving the fronto-parietal white matter and the corpus callosum and (ii) multiple diffuse susceptibility weighted imaging (SWI) hypointense foci, infra and supratentorial, predominantly bithalamic, suggestive of microhemorrhage or alternatively microthrombi. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) RNA was detected in the cerebrospinal fluid. Our findings suggest the occurrence of vascular damage, predominantly involving microvessels. The underlying mechanisms, which include direct and indirect penetration of the virus to the central nervous system and systemic cardiorespiratory complications, are yet to be elucidated, and a direct correlation with SARS-CoV-2 infection remains uncertain.
