Panobinostat ic50 depression is graded by severity into mild, moderate, severe, and psychotic. DSM-IV-TR lists a series of cross-sectional specifiers of the major depressive episode (catatonic, melancholic, atypical, postpartum), and longitudinal course specifiers (chronic, ie, full criteria for a major depressive episode met for at least 2 years; full interepisode recovery present or absent; seasonal; Inhibitors,research,lifescience,medical rapid cycling). The DSM-IV-TR diagnostic criteria for depression, based on the categorical distinction between bipolar disorders and depressive

disorders, are the opposite of Kraepelin’s unitary view of mood disorders. According to Kraepelin,2 mania, hypomania, depression, mixed states, and mood temperaments were variants of the same disorder, manic-depressive insanity (illness). Manic mixed states (mixed mania/hypomania) and depressive mixed states (mixed depression) were one of the main building blocks supporting Kraepelin’s unitary view of mood disorders. Mixed states are different Inhibitors,research,lifescience,medical combinations of manic, hypomanic, Inhibitors,research,lifescience,medical and depressive symptoms in the same mood episode. A logical conclusion was that if symptoms

of opposite polarity could be present in the same episode, manic/hypomanic states and depressive states could not be distinct disorders. Also, recurrent depression (no history of mania or hypomania) was included in manicdepressive insanity by Kraepelin (i) because of its recurrent course; (ii) because manic episodes could have a later onset in its course; and Inhibitors,research,lifescience,medical (iii) because manic or hypomanic symptoms often co-occurred during depressions. In Kraepelin’s view, severe and less severe mood disorders were “without sharp boundaries,” and had “a common root with gradual transitions Inhibitors,research,lifescience,medical between the Individual forms.” Kraepelin’s view is the basis of the current continuity or spectrum view of mood disorders, based on

a dimensional approach which is the opposite of the DSM-IV-TR categorical approach (ie, clear boundaries among mood disorders). The focus of this review will be on the new advances in the classification and description of several forms of depression. The mood spectrum According to the 17-DMAG (Alvespimycin) HCl spectrum view of mood disorders,3-17 depression is not divided into independent categories as in DSM-IV-TR. Instead, several types of depression lie along a continuum, which does not have sharp boundaries between the categories, following a dimensional approach. The dimensional view of depression describes depression mainly by the grading of its severity and by associated features. Angst3-5 described bipolar I depression (history of mania) and several subtypes of bipolar II depression (history of hypomania) on the basis of the severity of hypomania (hypomania with and without functional impairment) and on the severity of depression (major depressive episode, dysthymia, minor depression, recurrent brief depression).
