Frequency and risk factors of psychological distress among individuals with epilepsy before and during the outbreak of the SARS-CoV-2 Omicron variant in China: an online questionnaire survey

TL;DR

The study found that the Omicron variant of SARS-CoV-2 increased psychological distress in people with epilepsy, especially those with low income or uncontrolled seizures.

Contribution

The study identifies new risk factors for psychological distress in people with epilepsy during the Omicron outbreak.

Findings

Psychological distress in people with epilepsy increased significantly during the Omicron outbreak.

Low household income (<5000 RMB) and uncontrolled seizures were key risk factors for psychological distress.

Seizure onset within 30 days before assessment predicted both distress and its worsening during the outbreak.

Abstract

The COVID-19 pandemic substantially increases the risk of severe psychological distress among people with epilepsy (PWE), especially those with monthly household income < 5000 RMB or with uncontrolled seizures. Patients with Kessler scores > 12 should consult a psychiatrist, especially during major disasters. This study was aimed to compare the frequency of psychological distress among Chinese PWE before and during the outbreak of the SARS-CoV-2 Omicron variant, and to identify risk factors for such distress.

In this prospective study, we collected sociodemographic data of PWE aged > 14 years, who were treated at our center during December 1 to 15, 2022. All participants completed the 6-item Kessler Psychological Distress Scale before the outbreak and again during the outbreak. Health visitors who were unrelated to those patients during the outbreak were included as a control. Multivariate logistic regression analysis was performed to identify risk factors of severe psychological distress and its exacerbation.

Of the 223 PWE, 127 were tested positive for SARS-CoV-2, while 174 of 218 controls were positive for SARS-CoV-2. The neurological symptoms were similar between PWE and controls with SARS-CoV-2. The average Kessler score of PWE was significantly higher during the outbreak than before it (9.93 ± 3.98 vs. 8.52 ± 0.23, P < 0.001). The average score of controls during the outbreak (5.146 ± 0.35, P < 0.001) was significantly lower than that of the PWE. We identified three independent predictors for severe psychological distress in PWE during the outbreak, i.e., monthly household income < 5000 RMB (OR = 0.252, 95%CI 0.064–0.998, P = 0.048), severe psychological distress before the outbreak (OR = 0.067, 95%CI 0.026–0.174, P < 0.001), and seizure onset within 30 days before the assessment during the outbreak (OR = 0.356, 95%CI 0.157–0.805, P = 0.013). Of the three predictors, the last one was also an independent predictor for exacerbation of psychological distress during the outbreak (OR = 0.302, 95%CI 0.123–0.741, P = 0.009).

Our analysis suggests that the COVID-19 pandemic has substantially increased psychological distress of individuals with epilepsy, regardless of the viral infection or not. Various neurological symptoms similar to those of “long COVID” appeared for the first time among these individuals during the Omicron outbreak, highlighting the need for clinicians to screen carefully for this condition. Management of epilepsy during the pandemic or a similar major disaster should focus on the control of seizures and maintenance of mental health, especially among those with monthly household incomes below 5000 RMB, suffering uncontrolled seizures and having a history of severe psychological distress.
