Modern understanding of psychosis: from brain disease to stress disorder. And some other important aspects of psychosis…

ABSTRACT In this editorial we try to summarise how we, in 2021, understand mental disorders in general, and psychoses in particular. We have tried to write it in a language that is understandable for our readers, including patients, relatives, students and professionals, without reducing its scientific validity or basis. During the last decade we have gained new insight in these disorders, and most textbooks are outdated and convey an old-fashioned understanding of the causes, the possible courses and the treatments needed for serious mental suffering.
