統合失調症の特異的な症状

Symptoms Specific to Schizophrenia

統合失調症に特異的な症状には，自我意識の障害，妄想気分と妄想知覚，連合弛緩や滅裂思考がある。さまざまな自我意識の障害に関連する症状をsense of agencyの観点からみると，意思作用の自己への過大帰属と過小帰属とまとめることができる。妄想知覚の背景には，知覚対象のコンテクストが失われる知覚の統合障害や妄想気分が認められ，ばらばらに断片化された知覚を再組織化，あるいは変容した世界を解釈する際に妄想に至ると考えられる。知覚の統合障害は連合弛緩や滅裂思考と大きく関連する。

Abstract

Symptoms specific to schizophrenia include self-disturbances, delusional perception and loosening of associations. Self-disturbances in schizophrenia can be explained from the standpoint of an abnormal sense of agency, such as thought broadcasting as an over-attribution of agency and thought insertion as an under-attribution of agency. Delusional perception is often accompanied by impairment of perceptual organization; delusional mood and delusions might result from the reorganization of the fragmented perceptual field, as well as a loss of reality. Impairment of perceptual organization is frequently related to the loosening of associations.
