This paper summarizes the various historiographical approaches, and its approach to the subject is closest to the conceptual history carried out by German Berrios in Cambridge. The study attempts to correlate the key actors and their works with the history of different scientific ideas, its differences, and the influences of foreign authors. The diseases, syndromes, symptoms and pathologizations in this historical period were also studied, justifying a constructionist perspective. Finally, the various therapies are discussed, from institutional to pharmacological and psychotherapeutical %K Concepts %K diseases %K history %K Portugal %K psychiatry %K scientific culture %U https://journals.sagepub.com/doi/full/10.1177/0957154X18756525
