Abstract: Episodic or cyclical nonaffective psychosis with rapid, full recovery between episodes does not fit into any clear diagnostic category. Patients exhibiting this pattern would clinically be assigned to DSM-5’s unspecified psychosis category or brief psychotic disorders. In the psychiatric literature, this type of illness is frequently referred to as “cycloid psychosis.” Most researchers see this category of psychotic illness as a distinct diagnosis from the schizophrenic or affective disorders.
