[The time-structure of a manic-depressive psychosis (author's transl)]

Some ideas about the desynchronisation and the restabilisation of the diurnal time-structure in the mood-and-drive system are the background for some hypotheses about the determination of the course and the theory of mixed states of manic-depressive psychoses. A model given in graphs is compared with empiric material from a typical casus, which could be shown with its prodrom and some weeks of its course. The structure of dimensionality was studied by factor-analysis, the time structure was studied by autocorrelation technique. A development of the chronobiological theory seems to be of interest.
