Schizothymia is an affective disorder often associated with cyclothymia for its lessened severity as a schizophrenic affect disorder, much as cyclothymia is classed as a less severe bipolar mood disorder. A schizothymic personality consists of an affect that is cold, withdrawn or indifferent to the point of psychopathy in intimate interpersonal interactions, but is also able to achieve a relatively warm, open, receptive & sociable affect in some other specific situations. The separation of which, the personable from otherwise, is not governed by normally warranted stimuli for the change between the two temperaments, but rather is idiopathic, arising from no interpersonal source, and can be solely traced to the psychology of the individual in question.
