Inventário de depressão em transtornos neurológicos para a epilepsia (IDTN-E): Versão Brasileira de um instrumento de rastreamento

Introduction: Depression is the most common psychiatric comorbidity in epilepsy, being its identification frequently neglected in most epilepsy centers. Objective: To evaluate the performance of the Brazilian version of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) in a group of patients from a specialized center. Methods: The recently validated Brazilian version of the NDDI-E was applied to a group of 142 outpatients with epilepsy. We used the MINI-Plus as a gold standard to diagnosis major depressive episode. Results: Forty patients (28.2%) were depressed at the time of evaluation. The ROC curve analysis indicated that the cutoff at 15 (>15) represented the greatest dichotomy between depressed and nondepressed (sensitivity 70.0%, specificity of 87.3%, positive predictive value of 68.3% and negative predictive value of 88.1%). The use of lower cutoff points may eventually be adopted to provide greater sensitivity to the instrument. Conclusion: The Brazilian version of NDDI-E is a sensitive and practical tool that can help in tracking depression in epilepsy in order to reduce its underdiagnosis.
