Impact of COVID-19 on quality of life in people with epilepsy, and a multinational comparison of clinical and psychological impacts

Abstract

BackgroundThis study aimed to determine the relationship among the clinical, logistic, and psychological impacts of COVID-19 on people with epilepsy (PWE), and the impact of COVID-19 on the quality of life. MethodThis is a cross-sectional anonymized web-based study on PWE, using an online questionnaire to assess the clinical, logistic, and psychological impacts of COVID-19, including Hospital Anxiety Depression Scale (HADS) and Quality of Life in Epilepsy Inventory (QOLIE-31). Result461 patients were recruited, with a mean age of 39.21 ± 15.88 years, majority female (50.1%), with focal epilepsy (54.0%), and experienced seizures at least once yearly (62.5%). There were 13.0% experienced seizure worsening during COVID-19 period, which were associated with baseline seizures frequency ≥ 1 per month (32.0% vs. 6.2%, p < 0.001), worries of seizure worsening (18.0% vs. 10.9%, p < 0.001), difficulty to go emergency unit (24.4% vs. 10.4%, p < 0.001), AEDs ran out of stock (23.2% vs. 11.6%, p < 0.05), self-adjustment of AED dosages (26.4% vs. 11.3%, p < 0.001), inadequate sleep (22.4% vs. 9.2%, p < 0.001), and stress (23.4% vs.10.1%, p < 0.01). Participants experiencing seizure worsening reported greater anxiety (8.10 ± 5.011 vs. 4.84 ± 3.989, p < 0.001) and depression (6.05 ± 3.868 vs. 3.86 ± 3.589, p < 0.001). Logistic regression showed baseline seizures frequency >1 per month (OR, 14.10) followed by anxiety (OR, 3.90), inadequate sleep (OR, 0.37), and treated in UMMC (OR, 0.31) as the predictors for seizure worsening during COVID-19 period. Poorer total QOLIE-31 score was noted in those with seizure worsening (48.01 ± 13.040 vs. 62.15 ± 15.222, p < 0.001). Stepwise regression highlighted depression as the main negative predictor for quality of life (β = −0.372, p < 0.001), followed by anxiety (β = -0.345, p < 0.001). ConclusionA significant number of PWE experienced seizure worsening during COVID-19 period, which was related to the clinical, logistic, and psychological factors. Quality of life was affected by the seizure worsening and the psychological stress.
