Abstract

A new diagnostic system for organic psychiatry is presented. We first define "organic psychiatry", and then give the theoretical basis for conceiving organic psychiatric disorders in terms of hypothetical psychopathogenetic processes, HPP:s. Such hypothetical disorders are not strictly identical to the clusters of symptoms in which they typically manifest themselves, since the symptoms may be concealed or modified by intervening factors in non typical circumstances and/or in the simultaneous presence of several disorders. The six basic disorders in our system are Astheno Emotional Disorder (AED), Somnolence Sopor Coma Disorder (SSCD), Hallucination Coenestopathy Depersonalisation Disorder (HCDD), Confusional Disorder (CD), Emotional Motivational Blunting Disorder (EMD) and Korsakoff's Amnestic Disorder (KAD). We describe their usual etiologies, their typical symptoms and course, and some forms of interaction between them
