The concepts: Disturbed state of consciousness and psychosis.
Acta psychiatrica Scandinavica February 1, 1975 A Aggernaes
The paper offers a theoretical analysis of the concepts 'disturbed state of consciousness' (DSC) and 'psychosis,' aiming to define them in ways consistent with Continental clinical psychiatric practice. For DSC, two points are emphasized: that classifying a state as pathological involves evaluating the client's ability to change it voluntarily, and that stating a DSC was present during a time interval implies all experiences during that interval were abnormal, in the broad sense including William James' 'fringe' and 'embeddedness.' For psychosis, reality testing remains central, provided a clear distinction is made between theoretical full-blown syndromes and concrete syndromes with fewer symptoms.
