Abstract

Highlights: The prevalence of seizure phobia was 27.5% among the participants of the study. Seizure phobia was associated with female gender, anxiety disorders, a past major depressive episode, and psychogenic non-epileptic seizures. Seizure phobia was not associated with the severity or duration of epilepsy. Seizure phobia is a distinct psychiatric disorder worthy of further exploration. Abstract: Objective: Epilepsy is characterized by unpredictable attacks. Hence, people with epilepsy (PWE) may develop anxious anticipation of upcoming seizures. Seizure phobia is an anxiety disorder wherein seizure anticipatory situations trigger fear, accompanied by avoidance behaviors. Research on seizure phobia among PWE is scarce. Therefore, we aimed to describe the diagnosis of seizure phobia and its association with demographic, psychiatric and neurological variables. Methods: This is a cross-sectional study of adult PWE in a tertiary epilepsy outpatient clinic. Data were collected from semi-structured interviews, demographic questionnaires and medical records. Patients with and without seizure phobia were compared in terms of sociodemographic, psychiatric, and neurological variables. A logistic regression analysis was performed to identify variables that predicted seizure phobia. Results: Among 69 PWE included in the study, 19 (27.5%) were diagnosed with seizure phobia. In comparison with PWE without seizure phobia, PWE with seizure phobia were predominantly female (84.2% vs 44.2%, p = 0.005), and had more comorbid anxiety disorders (84.2% vs 34.9%, p = 0.01), past major depressive episode (MDE) (63.2% vs 20.9%, p = 0.003), and post-traumatic stress disorder (26.3% vs 7%, p = 0.05). There was a significant association between seizure phobia and comorbid psychogenic non-epileptic seizures (36.8% vs 11.6%, p = 0.034). However, no significant association was found with epilepsy-related variables. A multivariate logistic regression model indicated anxiety and a past MDE as predictive factors for seizure phobia ( R 2 = 0.43). Conclusion: Seizure phobia is a distinct psychiatric entity among PWE. Further research is required to understand its etiology, risk factors, and potential interventions for these patients.
