Summary
Mixed state (MS) refers to an affective condition in which depressive and manic symptoms are simultaneously present. It may manifest as a transitional condition, bridging one phase of the illness with another, or may exist as an independent clinical attack. In the latter case, along with mania and depression, MS represents a major phase of manic-depressive illness; however, it is often misdiagnosed because of its pleomorphic symptomatological presentation, as well as underdiagnosed because of inadequate diagnostic delimitation. There is no terminological uniformity in the literature, and there is a regrettable tendency to use terms such as “mixed state,” “mixed mania,” “depression during mania,” and “dysphoric mania” interchangeably. In this chapter, we critically review the empirical literature on different definitions of MS, focusing on their clinical validity. In doing so, we devote special attention to the evolution of MS in the overall course of manic-depressive illness.
Definition of bipolar mixed states
In the original description of MS given by Kraepelin (1899) and by his pupil Weygandt (1899), one or more of the main psychopathological features of mania (mood, cognition, psychomotor activity) were replaced by one or more of the main features of depression, and vice versa. This approach led Kraepelin to postulate six putative subtypes: (1) depression with flight of ideas; (2) excited depression; (3) depressive-anxious mania; (4) unproductive mania; (5) inhibited mania; and (6) manic stupor.
