Abstract

The paper discusses the emergence of the concept of polarity out of the rubric of manic depressive illness. The polar types are defined and changes in polarity, frequency and similarities and the differences between them are discussed. The author ventures to suggest that a change in the polarity viz., occurrence of mania in depressive or of depressive episodes in mania to be designated "LAP Phenomenon" after Leonhard, Angst and Perris who have been mainly responsible for the concept.
