Psychiatric and intellectual comorbidities are common in patients with epilepsy. However, data on the use of antiepileptic drugs in these patients are still lacking. This study assessed the real-world effectiveness and safety/tolerability of eslicarbazepine acetate (ESL) in patients with intellectual disability and psychiatric comorbidities, including a separate analysis specifically in those with depression, using data from the Euro-Esli study. Effectiveness measures included responder and seizure freedom rates. Safety and tolerability were assessed by evaluating adverse events (AEs) and ESL discontinuation due to AEs, respectively. Of the 2058 patients initially included in the Euro-Esli study, 952 patients had intellectual disability data available, 1138 had psychiatric comorbidity data available and 1134 had depression data available. Of those who had intellectual or psychiatric comorbidity data available, 11.3% (108/952) suffered from intellectual disability, 24.9% (283/1138) had a psychiatric disorder, including depression, and 12.4% (141/1134) specifically had depression. Responder and seizure freedom rates were generally comparable between patients with psychiatric comorbidity and those without, and patients with depression and those without. However, responder and seizure freedom rates were significantly lower in patients with intellectual disability compared with those without. Overall, patients with psychiatric and intellectual comorbidities experienced more AEs and AEs leading to ESL discontinuation than patients without these comorbidities. The incidence of psychiatric AEs was not significantly different for patients with psychiatric comorbidities or depression than those without, and the incidence of cognitive AEs was not significantly different for patients with intellectual disability than those without. These findings suggest that ESL is effective in patients with psychiatric and intellectual comorbidities and that its use in these patients is unlikely to exacerbate existing psychiatric or cognitive disturbances.
