Secondary Psychosis Spectrum Disorder

Numerous clinical issues exist regarding the diagnostic criteria in psychiatry. To address these issues, this paper reconstructs depression and atypical psychosis through a symptomatic framework. From depression, self-infringement psychosis is derived, emphasizing its psychotic symptoms. From atypical psychosis, bewildered-state psychosis is derived, elucidating its characteristic pathology. Furthermore, this paper proposes a comprehensive concept of secondary psychosis spectrum disorder, demonstrating that stress reactions and depression serve as a common foundation for these disorders. Their basis transitions from minimal introversion through normal state to maximal introversion along fluctuations in introversion, i.e., introversion spectrum, and these disorders arise secondarily from this spectrum. Nevertheless, given that this concept is still in its nascent stages, further research in this area is expected to yield significant advancements in psychiatry.
