Interictal depressive episodes/disorders are the most frequent form of depression and, by the same token, the most frequent psychiatric co-morbidity in PWE, with prevalence rates ranging from 11% to 60% . They may mimic major depression, dysthymic, minor depressive and bipolar disorders described in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). In a significant number of patients, however, depression may present with atypical clinical characteristics. In primary depressive disorders, the difference between major depression and dysthymic disorder is based largely on severity, persistence and chronicity. According to DSM-IV criteria, symptoms in both disorders may include combinations of depressed mood, anhedonia, feelings of worthlessness and guilt, decreased ability to concentrate, recurrent thoughts of death and neurovegetative symptoms (i.e. weight loss or gain, insomnia or hypersomnia, psychomotor agitation or retardation and fatigue). The diagnosis of a major depressive episode requires at least 2 weeks of either a depressed mood or anhedonia accompanied by four or more of the additional symptoms cited above occurring every day and lasting the majority of the day. In contrast, dysthymic disorder is a more chronic but less intense process, with symptoms present more days than not for at least 2 years. Minor depression is similar to major depression in duration but encompasses at least two but fewer than five of the depressive symptoms noted above.
