Definition

A disorder in which there is an insidious but progressive development of oddities of conduct, inability to meet the demands of society, and decline in total performance. The characteristic negative features of residual schizophrenia (e.g. blunting of affect and loss of volition) develop without being preceded by any overt psychotic symptoms.

F20.6 in national editions

Countries report with their own edition of ICD-10. Most keep the WHO code and add more specific codes beneath it.
