Abstract Psychiatric disorders are frequent among patients with epilepsy. Data in the literature have shown a heterogeneous clinical presentation of psychiatric disorders in patients with epilepsy. Interictal dysphoric disorder could be a specific psychiatric comorbidity associated with epilepsy, primarily in patients treated in tertiary centers.Objective The present study aimed to determine the prevalence of interictal dysphoric disorder among patients with epilepsy who were followed in two tertiary epilepsy services in Brazil. Method Sixty-five patients with epilepsy completed the Portuguese version of the Interictal Dysphoric Disorder Inventory. Results Thirty-three (50.7%) patients fulfilled the diagnostic criteria for interictal dysphoric disorder, although all participants answered positively to having at least one key symptom. Conclusion The high rate of patients with epilepsy who fulfilled the diagnosis of interictal dysphoric disorder confirms an association between epilepsy and psychiatric disorders. However, there is clearly a need to improve diagnostic tools to allow better differentiation between interictal dysphoric disorder and other psychiatric disorders.

Transtornos psiquiátricos são frequentes entre pacientes com epilepsia. Estudos evidenciam apresentações clínicas heterogêneas neste grupo. O transtorno disfórico interictal pode um transtorno específico destes pacientes, particularmente naqueles acompanhados em centros terciários.Objetivo Determinar a prevalência de transtorno disfórico interictal entre pacientes com epilepsia atendidos em dois serviços terciários de epilepsia do Brasil. Método Sessenta e cinco pacientes foram convidados a responder a versão brasileira do Interictal Dysphoric Disorder Inventory adaptado e validado para o Português. Resultados Trinta e três pacientes (50,7%) preencheram critérios para transtorno disfórico interictal, embora todos os entrevistados tenham afirmado que são acometidos por ao menos um dos sintomas-chave. Conclusão A alta prevalência de transtorno disfórico interictal em pacientes com epilepsia pode ser um indício da associação entre epilepsia e transtornos psiquiátricos. No entanto, é necessário melhorar a acurácia dos instrumentos de diagnóstico para poder diferenciar casos de transtorno disfórico interictal de outros transtornos psiquiátricos.
