Acute exogenous reactive types (AERT), exogenous, somatogenic, organic and symptomatic psychoses have essentially identical or very similar symptoms. The terms can thus be used promiscue. The concept of symptomatic psychosis is according to the common convention superior to other psychoses it appears, however to be superfluous. It must involve direct or indirect brain damage. It seems therefore more useful to use for AERT the term organic psychosis. There is no reason why to derive all forms of AERT from impaired consciousness, as lucid consciousness being a global psychic function makes their diagnosis possible and episodic interpolated qualitative disorders of consciousness could not occur. The organic psychosyndrome is characterized by a reduction of psychic functions, the majority with an irreversible course. In case of a marked lesion of certain brain structures the topical characteristics may be reflected in psychic symptoms, more frequently, however, the premorbid structure of the personality and its compensating mechanisms play a part. Therefore it is justified to separate the local psychosyndrome which from the external aspect is identical with psychoendocrine psychosyndrome. For the diagnosis of symptomatic psychic disorders K. Schneider's and Weitbrechts preprequisites are essential. AERT may end by cure, death or development into organic psychosyndrome.
急性外源性反应型（AERT）、外源性、躯体性、器质性和症状性精神病具有基本相同或非常相似的症状。因此这些术语可以混用。症状性精神病的概念按照通常惯例优于其他精神病，然而它似乎是多余的。它必定涉及直接或间接的脑损伤。因此，对于AERT使用“器质性精神病”这一术语似乎更有用。没有理由认为所有形式的AERT都源于意识障碍，因为清醒意识作为一种整体心理功能使得对它们的诊断成为可能，而且意识的发作性插入性质性障碍不可能发生。器质性精神综合征的特点是心理功能减退，大多数呈不可逆病程。在某些脑结构有明显病变的情况下，局部特征可能反映在精神症状中，但更常见的是，病前人格结构及其代偿机制起作用。因此，将从外部表现与精神内分泌精神综合征相同的局部精神综合征区分开来是合理的。对于症状性精神障碍的诊断，K. 施奈德和魏特布雷希特的先决条件至关重要。AERT可能以治愈、死亡或发展为器质性精神综合征而告终。
