Are the seizures under control or unnoticed? Electroclinical evaluation of epilepsy with eyelid myoclonia.

PURPOSE: In this study, patients with epilepsy with eyelid myoclonia (E-EM) were evaluated according to their EEG findings, seizure outcomes, and their consistency with the final ictal EEG findings. We also investigated the possible prognostic factors. METHODS: Patients with E-EM and at least two years of follow-up in our clinic were included in the study. We analyzed the presence of eyelid myoclonia, absence and myoclonic seizures, and generalized tonic-clonic seizures for the prior two years and then verified with the latest ictal EEG features. Video-EEGs were analyzed according to the background activity, the existence of generalized spike-wave discharge or polyspike-wave complexes, focal spike-wave discharge, photoparoxysmal responses, and fast activity. RESULTS: 21 patients were involved in this study. In six patients, the seizures were undetected on the first EEGs, whereas they were detected on subsequent ones. The seizures were captured on the first EEGs of six patients; however, they disappeared on subsequent ones. Only one patient had seizures detected on every EEG. The consistency of the seizures was variable in eight patients. At the final follow-up, seizures were reported as being under control for more than two years in 12 patients, according to patients and their parents' reports. However, ictal EEG findings were detected in six of these patients. No electroclinical feature was associated with seizure freedom. CONCLUSION: This study provides further evidence that seizure freedom in E-EM patients is overestimated. The patients and their parents may not be aware of the seizures. Therefore, video-EEG monitorization is essential during follow-up.

What is the price of residence in rural areas for patients with epilepsy?

INTRODUCTION: We aimed to investigate the effects of the urban or rural dwelling of patients with epilepsy living in Giresun on their use of health services, quality of life, and self-efficacy. METHODS: In this cross-sectional study, patients with epilepsy who were admitted to the neurology outpatient clinic between January 2022 and August 2022 were evaluated. All the participants were individually interviewed to complete the Epilepsy Self-Efficacy Scale (ESES) and Quality of Life in Epilepsy Inventory (QOLIE-10) questionnaire. The frequency of admission to the emergency department, neurology outpatient clinic, and general practitioner clinic where the primary reason for the visit was epilepsy in the last year was determined using the hospital database. RESULTS: This study was composed of 109 patients. The rural dwelling was found in 45% of the participants. The mean age of seizure onset was significantly lower in patients dwelling in rural areas Mean GP and ED visits didn't differ according to dwelling. On the other hand, mean neurology outpatient clinic visits were significantly lower in patients living in rural areas. The QOLIE-10 didn't differ according to the dwelling. However, lower ESES results were obtained in patients living in rural areas. CONCLUSION: This study shows that there is a disparity in neurologist visits among patients with epilepsy dwelling in rural areas. Furthermore, lower ESES scores were found in these patients. Educational interventions should be addressed particularly to the patients dwelling in rural areas to strengthen self-efficacy, and fill the gaps for the shortage of health personnel and qualified health care.

Ictal Fear during parietal seizures.

Ictal fear is characterized by subjective fear sensation and consistent clinical manifestations during seizures. This phenomenon is rarely observed in parietal seizures. We report anatomical electroclinical correlations of an SEEG-recorded seizure with prominent fear semiology. Seizure onset zone was quantified using the Connectivity Epileptogenicity Index method (cEI). Occurrence of fear during seizures was related to the involvement of the left inferior parietal cortex and the superior temporal gyrus without amygdala involvement. Our case confirms that parietal seizure can produce ictal fear without concomitant involvement of the limbic temporal network.

Serum Levels of Neuropeptides in Epileptic Encephalopathy With Spike-and-Wave Activation in Sleep.

BACKGROUND: Epileptic encephalopathy with spike-and-wave activation in sleep (EE-SWAS) is a syndrome of childhood, characterized by diffuse or generalized spike-wave activity in electroencephalography during non-rapid eye movement sleep. Neuropeptides have been demonstrated in several studies to function in the sleep-wake cycle and display convulsant and anticonvulsant features. In this study, we aimed to investigate the relationship between EE-SWAS and neuropeptides such as dynorphin, galanin, ghrelin, leptin, melatonin, and orexin. METHODS: This multicenter study was conducted from July 2019 to January 2021. There were three groups: Group 1 contained patients with EE-SWAS. Group 2 consisted of patients with self-limited focal epilepsy of childhood (SeLFE), and group 3 was the control group. Levels of neuropeptides were compared in the sera of these three groups. RESULTS: There were 59 children aged between four and 15 years. Group 1 contained 14 children, group 2 contained 24 children, and group 3 contained 21 children. The level of leptin is higher and the level of melatonin is lower in group 1 than in group 3 (P = 0.01 and P = 0.005, respectively). In group 3, the level of orexin was lower than in both groups 2 and 3 (P = 0.01 and P = 0.01). CONCLUSIONS: These data show that the level of leptin was higher and the level of melatonin was lower in patients with EE-SWAS than in the control group. Furthermore, patients with EE-SWAS had lower orexin levels than both the control group and patients with SeLFE. Further research is required to understand the potential role of these neuropeptides in the pathophysiology of EE-SWAS.

Increased neuropil antibody prevalence in COVID-19 patients with acute ischemic stroke.

OBJECTIVES: COVID-19 infection is associated with an increased risk of acute ischemic stroke (AIS). Although the underlying mechanisms are largely unknown, autoimmunity has been implicated as a potential role player. METHODS: To investigate the presence and clinical impact of neuronal cell surface antibodies in COVID-19 associated AIS, patients with COVID-19 pneumonia and AIS (n = 30), COVID-19 pneumonia without AIS (n = 32) and AIS without COVID-19 infection (n = 27) were recruited. Serum anti-neuronal antibodies directed against well-characterized and novel cell surface antibodies were evaluated by cell-based assays and indirect immunohistochemistry, respectively. RESULTS: None of the recruited patients displayed well-characterized neuronal cell surface antibodies. Ten patients in the COVID-19 pneumonia with AIS group and three patients in the COVID-19 pneumonia without AIS group exhibited antibodies to neuropil of hippocampus and cerebellum. Neuropil-antibody positive patients showed trends towards milder clinical severity and reduced blood levels of inflammation factors. CONCLUSION: Our results confirm the presence of neuropil antibodies in patients with COVID-19 infection and identify a putative antibody-driven association between AIS and COVID-19. The antigenic targets and potential pathogenic action of these antibodies need to be further explored.
