COVID-19 vaccination-related exacerbation of seizures in persons with epilepsy.

Although vaccines are generally safe in persons with epilepsy (PWE), seizures can be associated with vaccination, including COVID-19. This study assessed the occurrence of COVID-19 vaccination-related seizure exacerbations in PWE. Adult PWE who had received a COVID-19 vaccine were consecutively recruited at a tertiary epilepsy clinic between June 2021 and April 2022. Patient demographics, including epilepsy history, vaccination details, and reported adverse effects were recorded. Seizure exacerbation, defined as occurring within one week of vaccination, was assessed. Five hundred and thirty PWE received the COVID-19 vaccine. 75 % received the Comirnaty (Pfizer) vaccine as their initial dose. Most patients (72 %) were taking ≥ 2 antiseizure medications (ASM) and had focal epilepsy (73 %). One-third were 12 months seizure free at their first vaccination. 13 patients (2.5 %) reported a seizure exacerbation following their first vaccination, three of whom required admission. None were seizure-free at baseline. Six of these patients (46 %) had a further exacerbation of seizures with their second vaccine. An additional four patients reported increased seizures only with the second vaccine dose. Seizure exacerbations are infrequently associated with COVID-19 vaccination, mainly in patients with ongoing seizures. The likelihood of COVID-19 infection complications in PWE outweighs the risk of vaccination-related seizure exacerbations.

Recalling the COVID-19 lockdown: Insights from patients with epilepsy.

PURPOSE: The purpose of our study was to explore health changes among people with epilepsy (PWE) during a national COVID-19 lockdown in the context of patients' clinical characteristics and their experience of receiving epilepsy-related medical services. METHODS: A questionnaire was distributed for adult PWE both online and at a tertiary epilepsy center after the end of a national lockdown in Lithuania. PWE were asked to evaluate their health status during the lockdown and estimate changes in their seizure patterns. Additional questions concerned the accessibility and quality of epilepsy-related consultations. RESULTS: The study sample consisted of 143 PWE (59 [41.3%] male, mean age 35.1 ±â€¯13.4 years), 94 (65.7%) completed the survey in person, 49 (34.3%) - online. A deterioration in reported physical and mental health during lockdown was observed (Z = -4.604, p < 0.0001 and Z = -4.253, p < 0.0001, respectively) and 22 (15.4%) PWE reported seizure exacerbation. In an ordinal logistic regression model (analysis of data from all participants), baseline seizure frequency (b = 0.413, p = 0.031), reported physical health before lockdown (b = -0.462, p = 0.031) and the ease of proper antiepileptic drug (AED) use during the imposed restrictions (b = -0.535, p = 0.006) were statistically significant variables associated with changes in seizure frequency. The latter were not affected by modifications in AED use (Mann-Whitney U = 1127.0, p = 0.307) irrespective of the data collection method. With teleconsultations being predominant during the lockdown, an overall decline in the quality of epilepsy-related consultations was observed (Z = -2.895, p = 0.004). Among all participants, 46 (32.2%) lost an epilepsy-related consultation or medical service because of the lockdown. This loss was found to be associated with seizure exacerbation (Mann-Whitney U = 1622.5, p = 0.046). CONCLUSION: Our study indicates that a national COVID-19 lockdown may have led to worse seizure control and health status in some PWE. Easy access to AEDs and their appropriate use may be especially useful to prevent seizure exacerbation during strict COVID-19 restrictions. The quality and accessibility of remote epilepsy-related consultations was suboptimal and may require further improvement during disruption of in-person services.

COVID-19 outbreak: The impact of stress on seizures in patients with epilepsy.

OBJECTIVE: Stress is a known trigger for seizures in patients with epilepsy (PWE). However, the association between stress and seizures has not been thoroughly investigated. In December 2019, an outbreak of coronavirus disease (COVID-19) occurred in Wuhan, Hubei province, China, causing tremendous collateral stress. This study was designed to evaluate the influence of the COVID-19 outbreak on seizures in PWE in the most severely affected area, Wuhan, and its surrounding cities. METHODS: In this single-center, cross-sectional study, PWE were surveyed via online questionnaires between February 23 and March 5, 2020. Collected data included demographic information, epilepsy-related characteristics (seizure type, frequency, antiepileptic drugs [AEDs], and medication management), direct and perceived threat of COVID-19, and changes in seizures during the outbreak. Psychological comorbidities were evaluated by the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7 items, and Insomnia Severity Index (ISI). Multivariate logistic regression was used to identify precipitants for seizure exacerbation. RESULTS: We received 362 completed questionnaires after excluding 12 duplicates (response rate = 63.51%). A total of 31 (8.56%) patients had increased seizures during the outbreak. Exposure history to COVID-19 (P = .001), uncontrolled seizure after AED therapy (P = .020), seizure frequency of two or more times per month before the outbreak (P = .005), change of AED regimen during the outbreak (AED reduction, withdrawal, replacement, skipping altogether; P = .002), and worry about the adverse effect of the outbreak on overall seizure-related issues (severity = moderate to critical; P = .038) were risk factors for increased seizures. SIGNIFICANCE: A minority of PWE experienced seizure exacerbation during the outbreak of COVID-19. Stress, uncontrolled seizures, and inappropriate change in AED regimen were associated with increased seizures. Based on these findings, stress might be an independent precipitant for triggering seizures in some PWE.
