Depression in epilepsy: a common but often unrecognized comorbid malady.

Depressive disorders (DDs) represent the most frequent psychiatric comorbidity in epilepsy (1-5). Despite their relatively high prevalence, DDs remain unrecognized and untreated in many patients with epilepsy. The purpose of this review is to examine the reasons behind the failure to recognize and treat DDs in epilepsy. We highlight the essential epidemiologic, etiopathogenic, and clinical aspects that need to be considered in the evaluation of every epileptic patient and dedicate the last section of this paper to the review of the most relevant treatment issues. If we are successful in our goals, the reader will be impressed by the significant impact of DDs on the quality of life of these patients, and by the need to investigate treatment modalities with the same scientific rigor used in the assessment of efficacy of antiepileptic drugs in the control of seizures.
