This study aims to establish how perceptions regarding neurosyphilitic patients have been constructed at Göteborgs hospital and S:t Jörgens sjukhus during the time period 1918-1945. The research questions intend to identify which loaded descriptions and perceptions construct the neurosyphilitic patient, as well as how these are expressed in the various situations and meetings that define a patient's admitted time in the asylum. The source material consists of patient journals and department notes which were analyzed and categorized in accordance with the different contexts and situations, in which loaded descriptions were used to ascribe a certain behavior of the patient. Foucault's concept of disciplinary power constitutes the theoretical framework of this study. A qualitative content analysis was employed to thematize the structure of the result, as well as to enable the interpretation and analysis of the content of the source material. Accordingly, the results are structured and presented in a chronological manner that represents a patient's journey, from the first enlistment to final discharge, through the asylum's treatment process. The results display that patients were ascribed with loaded descriptions in connection to the themes derived from the different practices of the institution. Furthermore, perceptions about the patients were primarily constructed in relation to how the patient submitted to the regulations, order, and regularities of the institution.
