"A nosological nuisance, but a clinical reality", that is how psychiatrists Andreas Marneros and Hagop Akiskal once described schizoaffective disorder (SAD), aptly expressing a widely held view in the field and arguing for the necessity of the diagnosis. On the other hand, critics have emphasized weaknesses in the conception of schizoaffective disorder. Gin S. Malhi, to name only one of the most outspoken experts, called it "a total fabrication". The authors of DSM-5 and ICD-11, however, see a clinical need for they retained the diagnosis in their manuals, although in modified form, hoping to improve its supposedly low reliability.

坚持精神分裂症的诊断概念合理吗？

精神病医生Andreas Marneros和Hagop Akiskal曾经描述过精神分裂症（SAD），这在精神病学家中是一种听上去很麻烦的事情，但实际上是一种临床现实，恰当地表达了这一领域的广泛观点并提出了诊断的必要性。另一方面，批评家们强调了情感分裂性障碍概念的弱点。金·马里（Gin S. Malhi）仅是最直言不讳的专家之一，称之为“完全捏造”。然而，DSM-5和ICD-11的作者看到了临床需求，尽管修改后的形式仍保留了手册中的诊断内容，以期改善其所谓的低可靠性。
