Inventário de Depress？o em Transtornos Neurológicos para a Epilepsia (IDTN-E): vers？o 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.
