Department of Psychiatry, Umeå University, Sweden.

In this paper the author highlights the importance that the classificatory work carried out by Leonhard has had for recent international developments in the classification of mental disorders. In particular, the diagnostic relevance of a distinction between bipolar and unipolar affective disorders and the separation of the cycloid psychotic disorders from other major psychoses is underscored.
