Abstract: | Background and PurposeObsessive-compulsive symptoms (OCS) in people with epilepsy (PWE) have not been studied systematically. We evaluated the severity, predictors, and psychosocial impact of OCS in PWE.MethodsWe recruited PWE who visited our epilepsy clinic and age-, gender-, and education-matched healthy controls. Both PWE and healthy controls completed the Maudsley Obsessional-Compulsive Inventory (MOCI), which measures OCS. PWE also completed the Beck Depression Inventory (BDI) and the Quality of Life in Epilepsy Inventory-31 (QOLIE-31). We examined the severity of OCS in PWE relative to healthy controls. Predictors of OCS and the QOLIE-31 score were measured by regression analyses. A path analysis model was constructed to verify interrelations between the variables.ResultsThe MOCI total score was significantly higher in PWE than in healthy controls (p=0.002). OCS were found in 20% of eligible patients. The strongest predictor of the MOCI total score was the BDI score (β=0.417, p<0.001), followed by EEG abnormality (β=0.194, p<0.001) and etiology (β=0.107, p=0.031). Epileptic syndrome, the side of the epileptic focus, and action mechanisms of antiepileptic drugs did not affect the MOCI total score. The strongest predictor of the QOLIE-31 overall score was the BDI score (β=-0.569, p<0.001), followed by seizure control (β=-0.163, p<0.001) and the MOCI total score (β=-0.148, p=0.001). The MOCI total score directly affected the QOLIE-31 overall score and also exerted indirect effects on the QOLIE-31 overall score through seizure control and the BDI score.ConclusionsOCS are more likely to develop in PWE than in healthy people. The development of OCS appears to elicit psychosocial problems directly or indirectly by provoking depression or uncontrolled seizures. |
