The prevalence of depression in patients with epilepsy (PWE) is high. To elucidate the nature of depression in PWE, a comparison was made between PWE and patients with idiopathic depression (PWID), applying 3 test batteries: Beck Depression Inventory II (BDI-II), Center for Epidemiologic Studies Depression Scale (CES-D) and Buss–Perry Aggression Questionnaire (BAQ). The former 2 rating scales were developed to measure depressive symptoms, while the latter was designed to detect anger and aggressive states. As a result, the group of patients with PWE showed significantly higher BAQ scores in comparison to those with PWID. Further, the BAQ and BDI scores were closely related within a group of PWE, while BAQ and BDI scores were not correlated with each other within a group of PWID. With regard to pharmaceutical therapy, the safety of antidepressants, especially SSRIs, is well established. However, there has been only one randomized controlled trial (RCT) thus far, which failed to show a significant difference in efficacy between placebo and various antidepressants. In contrast, there are two RCTs regarding the efficacy of LTG. The clinical profile of the depressiolytic effects of LTG in PWE may be different from that of antidepressants in patients with idiopathic depression, in that BAQ is more sensitive measure than BDI or CES-D. It is now widely recognized that the failure to treat depression in PWE can result in serious consequences. However, even a fundamental question, such as whether antidepressants are as effective in this population as in PWID, remains to be answered.
