Unipolar mania

Unipolar mania is an unrecognized mental illness characterized by episodes of mania and normal mood, with the absence of depressive symptoms. The concept has its origins as far back as the year 1889, when the German psychiatrist Emil Kraepelin first used the term of "periodic mania" to refer to people with recurrent manic episodes and no depression. One year later, Carl Wernicke proposed that mania and depression should be viewed as separate disorders. As the time went on, unipolar mania became an invalid diagnosis due to its variations across different patients.[1] Currently patients with symptoms of mania, even in the absence of any depressive symptoms, would get the bipolar 1 diagnosis.[2]
