COVID-19 pandemic experiences among people with epilepsy: Effect on symptoms of co-occurring health conditions and fear of seizure

      Highlights

      • A considerable number of PWE experienced more symptoms of existing health conditions and fear of seizure during the initial year of the pandemic (2020).
      • Fear of seeking healthcare services was associated with both negative outcomes.
      • Assuring access to health care and reducing social isolation could potentially reduce negative outcomes for PWE.
      • The fear of seeking healthcare during COVID-19 was associated with both exacerbated co-occurring health conditions and increasing fear of seizure.
      • Social isolation was associated with exacerbated co-occurring health conditions during COVID-19.
      • Reduced access to physical healthcare was associated with increasing fear of seizures.

      Abstract

      Objective

      The Coronavirus disease 2019 (COVID-19) pandemic profoundly affected people worldwide, but little is known about how it impacted people with epilepsy (PWE). We examined the associations between COVID-19 stressors and health outcomes including increases in other health symptoms and fear of seizure among PWE.

      Methods

      This cross-sectional study used data from an online survey that asked about demographic characteristics, health conditions, and potential life stressors during COVID-19. Data were collected from October 30 to December 8, 2020. COVID-19 stressors were anger, anxiety, stress, healthcare access, fear of seeking healthcare, social isolation, sense of control over their lives, and alcohol consumption. A binary variable was created for each of these measures to indicate whether PWEs experienced a negative change versus a neutral or positive change. We used multivariable logistic regression to assess the associations of COVID-19 stressors with primary outcomes: exacerbated co-occurring health conditions and increasing fear of seizure during the pandemic.

      Results

      Of the 260 PWE included in the study, 165 (63.5%) were women; the average age was 38.7 years. During the survey administration period, 79 (30.3%) of the respondents reported exacerbated co-occurring health conditions, and 94 (36.2%) reported an increased fear of seizures. Regression results indicated that the fear of seeking healthcare during COVID-19 was associated with both exacerbated co-occurring health conditions (aOR 1.12; 95%CI 1.01–1.26) and increasing fear of seizure (aOR 2.31; 95%CI 1.14–4.68). Social isolation was associated with exacerbated co-occurring health conditions during COVID-19 (aOR 1.14; 95%CI 1.01–1.29). Reduced access to physical healthcare was associated with increasing fear of seizure (aOR 2.58; 95%CI 1.15–5.78).

      Conclusion

      A considerable number of PWE experienced more symptoms of existing health conditions and fear of seizure during the initial year of the pandemic (2020). Fear of seeking healthcare services was associated with both negative outcomes. Assuring access to health care and reducing social isolation could potentially reduce negative outcomes for PWE. It is necessary to provide adequate support for PWE to reduce risks as COVID-19 continues to be a health concern.

      ]. Therefore, increasing symptoms of co-occurring health conditions and fear of seizures are two important factors that impact the quality of life for PWE.
      The goal of this study was to identify potential relationships between COVID-19 biopsychosocial stressors and the fear of seizure or increasing symptoms of health conditions by using a national survey. We hypothesized that COVID-19 stressors, as well as the limitation of healthcare access experienced during the first year of the pandemic, would be associated with exacerbated co-occurring health conditions and an increased fear of experiencing seizures.

      2. Methods

      2.1 Study design

      Data were collected from adults aged 18 years or older with epilepsy from a cross-sectional, anonymous, and self-reported survey using a cloud-based Qualtrics XM tool. The study was deemed Non-human subjects research by the University of Utah Institutional Review Board.

      2.2 Participants

      Online surveys were conducted between the 30th of October and the 8th of December 2020.
      Qualtrics hosts a survey panel based on a list of several million previous survey participants. From this panel, 2,488 cases were invited to participate in the survey through e-mail. After completing the survey, participants were compensated in an amount agreed upon with Qualtrics when signing up for the panel. We conducted a pilot test of the survey administration with 10% of the initial sample to identify potential issues.
      To ensure data integrity, several strategies were applied:
      • We accepted one response from each IP address and excluded responses with a duplicate IP address (n = 7).
      • Short survey completion times (less than 7 min) were considered improbably fast responses and were excluded (n = 11).
      After applying the exclusion criteria, less than 0.8% of responses were identified as imprecise and ultimately omitted from the final sample.

      2.3 Measurements

      The online survey asked about COVID-19 experiences, demographic characteristics, and comorbidities. The COVID-19 experience measures were designed based on studies conducted during the early months of the COVID-19 pandemic and asked respondents about COVID-19 impacts [

      2.3.1 Increasing symptoms for health conditions, and fear of seizure during the pandemic.

      The primary outcomes of this study were self-reported increasing symptoms for health conditions, and fear of seizures. People with epilepsy were asked:
      “Please indicate whether you have been affected by any of the following as a result of COVID-19.
      • 1-
        Symptoms of pre-existing or current health conditions
      • 2-
        Fear of having a seizure”
      The respondents had four options, including increase, decrease, no change, and not applicable.
      The responses were coded as “1″ indicating that fear/symptoms have increased, and “0” indicating that fear/symptoms decreased, did not change, or were not applicable. We refer to reporting an increase in symptoms of pre-existing or current health conditions as “exacerbated co-occurring health conditions.”.

A binary variable was developed for each of these measures to indicate whether PWEs experienced negative changes versus neutral or positive changes. Negative changes included: decreased healthcare access and control over life and increased anger, anxiety, stress, fear of seeking healthcare, social isolation, and alcohol consumption.

      2.3.3 Demographic and medical history.

      Survey questions included demographic information (i.e., age, gender, racial identity, and level of education), and medical history (e.g., diagnosis with COVID-19, seizure freedom, and severity of seizures). Gender was categorized as men and women, and race/ethnicity was coded into four groups: non-Hispanic White (hereafter White), non-Hispanic Black (hereafter Black), Hispanic, and non-Hispanic others. Education levels were classified into four groups: less than high school, high school graduate, some college, and more than college.
      .
      For the medical history, the participants were asked, “Have you been diagnosed with COVID-19?” to measure the infection rate in the sample. To understand the impact of seizure severity and continued seizures, we used the Global Assessment of Severity of Epilepsy (GASE). The GASE estimates the severity of epilepsy based on the patient's self-reported global perception of severity using a single item previously found to be strongly associated with seizure frequency, treatment with multiple seizure medications, and multimorbidity [

Participants were asked, “Taking into account all aspects of your epilepsy, how would you rate its severity now?” (1) not at all severe, (2) a little severe, (3) somewhat severe, (4) moderately severe, (5) quite severe, (6) very severe, and (7) extremely severe. To identify seizure frequency, we used the following question from the Personal Impact of Epilepsy Scale (PIES) [

      ]: “In the past 12 months, what is the average number of seizures you have had per month?” Those who responded with one or more seizures were classified as having seizures in the past year and those who reported no seizures in the past year were classified as having no seizures in the past year.

      2.4 Statistical analysis

      The participants were divided into two groups for each dependent variable (i.e., people with or without each outcome). We first conducted descriptive analyses; continuous variables were reported as the mean ± standard deviation (SD), and categorical variables as frequencies (percentages). The statistical significance for intergroup differences (i.e., people with or without each outcome) was evaluated with Welch’s t-test for continuous variables, and Pearson’s chi-square test for categorical variables. After conducting descriptive analyses, we then applied logistic regression models to describe which variables were significantly associated with exacerbated co-occurring health conditions and fear of seizures among PWE during the Fall 2020 COVID-19 pandemic. In two separate models for co-occurring health conditions and fear of seizure, COVID stressors plus covariates that were associated with a p < 0.05 in the bivariate analysis were entered in multivariable logistic regression models. These logistic regression analyses for each dependent variable were designed to ascertain whether the COVID-19 stressors were associated with exacerbated co-occurring health conditions and increasing fear of seizure. Data were analyzed using the R programming environment (4.1.2), and adjusted odds ratios (aORs) and 95% confidence intervals (CIs) are presented for the final models; p‐values < 0.05 were considered statistically significant.

      3. Results

      3.1 Participant characteristics

      Among the 260 PWE included in this study, the mean age was 38.7 ± 14.8 years; 165 (63.5 %) were women, and 185 (71.2%) were White. More than 41% of respondents (n = 107) had a college degree or higher. A minority of PWE (n = 19; 7.3%) were diagnosed with COVID-19. Only 91 (35.0%) reported seizure freedom for more than one year, with a mean GASE of 3.16 ± 1.55 indicating “somewhat severe” epilepsy on average (Table 1). Approximately 30.3% of PWE had exacerbated co-occurring health conditions, and 36.1% reported increased fear of seizure during COVID-19.

      3.2 Stressors during COVID-19

      Among the COVID-19 stressors, the increase in stress and anxiety were the highest, 58% and 57%, respectively. Close to half of the sample reported an increase in social isolation, and three out of ten PWEs had a fear of seeking healthcare. More than 40 percent of the sample reported a decrease in control over life, and around a third of the PWEs had decreased access to health care.

      3.3 Changes in health condition and fear of seizure during COVID-19

      The COVID-19 stressors showed a significant relationship in the bivariate analysis of health conditions, while alcohol consumption did not significantly affect co-occurring health conditions (Table 2). The most remarkable differences were in stress and anxiety, where more than 83% of those who had exacerbated co-occurring health conditions reported increased anxiety and stress. Moreover, PWEs with increased social isolation were more likely to report exacerbated co-occurring health conditions (73.4% vs. 38.7%, p < 0.001).

      Alcohol consumption and changes in fear of seizures during COVID-19 were not significant in bivariate analysis, but other COVID-19 stressors were significant (Table 3). As seen in the health conditions' bivariate analysis, those with increased anxiety, stress, and fear of seizures demonstrated the greatest change, 78%, and 76%, respectively. People with epilepsy with increased social isolation were also more likely to report fear of seizure (64.9% vs. 40.4%, p < 0.001).

      3.4 Multivariate analysis

      The multivariate logistic regression for health conditions showed that PWE who reported fear of seeking healthcare were more likely to report exacerbated co-occurring health conditions (aOR 1.12; 95 CI% 1.01–1.26) (Fig. 2). Moreover, increased social isolation was significantly associated with exacerbated co-occurring health conditions (aOR 1.14; 95 CI% 1.01–1.29). Finally, being seizure-free in the previous year was associated with lower odds of exacerbated co-occurring health conditions (aOR 0.87; 95 CI% 0.77–0.98).

      Multivariate logistic regression analysis revealed that increased fear of seeking healthcare (aOR 2.31; 95%CI 1.14–4.68) was significantly associated with increased fear of seizure (Fig. 3). A decrease in physical healthcare access during COVID-19 was also associated with increased fear of seizure (aOR 2.58; 95%CI 1.15–5.78). A higher GASE score was associated with higher fear of seizure (aOR 1.46; 95%CI 1.17–1.82), while freedom from seizure within one year was associated with a lower likelihood of reporting fear of seizure (aOR 0.38; 95%CI 0.18–0.80).

The findings show both exacerbated co-occurring health conditions and increasing fear of seizure were relatively common and that both were associated with the fear of seeking healthcare during COVID-19. One plausible explanation is that the loss of some healthcare services among PWE could increase reported mental and physical symptoms [

A significant correlation between fear of seeking healthcare services and co-occurring health conditions, and fear of seizure can indicate high levels of general anxiety in a pandemic situation, and worsening anxiety could be triggered by the stress scenario during the pandemic.

      Consistent with the moderate to low risk of PWE, only about 7 percent of PWE in this sample indicated COVID-19 infection. The high prevalence of fear of having seizures and health comorbidities depict the greater spectrum of impact of COVID in PWE. This suggests that policies to mitigate COVID-19 and psychosocial reactions to the pandemic may have had more effects on PWE than COVID-19 itself. A notable proportion of respondents reported changes in stressors during the early pandemic period. These changes were associated with exacerbated co-occurring health conditions or increased fear of seizure in over half (51.5%) of our sample.

In our sample, 36% reported a fear of seizures since the pandemic, and those who were seizure-free during the past year were significantly less likely to report a fear of seizures in our survey. This suggests the possibility of increasing seizure frequency since the pandemic was associated with self-reported fear of seizures. Likewise, those who reported seizure freedom were less likely to report exacerbated co-occurring health conditions.

      ]. Therefore. higher psychological distress levels in our study may be critical indicators since they reported higher levels than most other studies, and it is crucial to identify psychological stressors sources amongst PWE who are more vulnerable during pandemics, such as PWE who live alone.
      The present study found no association between demographic characteristics and the outcomes, while higher seizure frequency was associated with exacerbated co-occurring health conditions and increasing fear of seizures. Seizure within one year was significantly associated with exacerbated co-occurring health conditions and increasing fear of seizure. Moreover, those with higher seizure severity (GASE) were more likely to have a fear of seizure during COVID-19. To improve healthcare for PWE, telehealth appointments could be conducted more frequently, and PWE with more severe conditions might be contacted proactively to ensure they have sufficient supplies of their antiseizure medications and psychological support with a variety of virtual tools.

      5. Study limitations

      The study is cross-sectional with questions about retrospective experiences, which limits our ability to evaluate the causal impact of variables on one another. All data were self-reported and could result in misclassification errors because of mistakes in reporting or difficulty accurately recalling changes in experiences since the beginning of the pandemic/lockdowns. Recruitment was conducted through the Qualtrics Panel [

      ], resulting in a sample of mainly people who were young, non-Hispanic White, educated, and women. People with epilepsy with poorer health status and those not as technologically savvy may have been underrepresented in this study. Online data collection might miss many more people with severe cases of epilepsy compared to the face-to-face interview, and consequently, our findings may not apply to all PWEs. The findings of our study could also be strengthened by additional information on pandemic severity and duration, the size and duration of the lockdown, patients' attitudes, and cultural traits. Moreover, our study suggests that changes in healthcare usage during the pandemic resulted in poor outcomes for PWE; however, our data could not distinguish between healthcare types, whether online or in-person. Previous studies suggest that increased telemedicine usage during the pandemic will benefit a considerable number of PWE [

      6. Conclusion

      The current COVID-19 pandemic has had a significant influence on PWE. People with epilepsy in this study had a substantial worsening of their seizure fear and health outcomes during the first few months of the pandemic. People with epilepsy who had reduced health care service access, fear of seeking health care, higher social isolation, and worse seizure characteristics were more susceptible to exacerbating co-occurring health conditions and fear of seizure during the pandemic. New modes of healthcare delivery, messaging about the safety and efficacy of these modes, and increased social support could improve health and seizure outcomes among PWE in the pandemic era.
