[Relevance of using the concept of reactional psychosis]

Reactive Psychosis can be a matter of controversy with respect to its pragmatic use. This is especially true in the Scandinavian countries, where two streams of opinion clash, one satisfied with the DSMIII's notion of "Brief Reactive Psychosis", supplemented with information on other Axes, and one stressing the advantage of retaining the wider range of the Scandinavian notion, and even of linking it up with the "Cycloid Psychosis". A certain consensus has emerged to recognize that further research is absolutely necessary to close the debate.
