[Mental Disorders from the Perspective of Interoception and Allostasis]

The classical concept of allostasis is proposed as a dynamic adaptive capacity to stressors. The overload of allostasis results in adaptive disorders, and then lead to various psychiatric disorders. The recent concept of allostasis explains not only physiological adaptation but also behavioural changes. Furthermore, the relationship between interoception and the sense of self as well as emotion has attracted attention in recent years. These conceptual extensions and their abnormalities could help in understanding the symptoms of schizophrenia.
