However, few articles detail the themes and mechanisms underlying those patients\u2019 delusions. To help bridge that gap, the authors conducted this retrospective descriptive study, including two samples of delusional homicidal patients, one from near present day and one from nearly a century ago. This study considered similarities observed in the literature (such as patients\u2019 sociodemographic profile, clinical data, and acting\u2010out dynamics), but also explored the characteristics of delusion. In the 2015\u20132019 sample, the typical patient profile was: single male (31.5\u00a0years old on average), without child, unemployed, and with psychiatric history (56.6%). Most patients suffered from schizophrenic disease (83%) with non\u2010systematized delusions exhibiting multiple themes in 80% of cases. Four principal types of delusion were observed: persecutive (100%), mystical (43.3%), megalomaniac (30%), and bodily (30%). The mechanisms were interpretative, hallucinatory, and intuitive. There was a societal influence in 23.3% of the cases (most often terrorist acts). The 1910\u20131914 historical sample revealed several differences: patients were older, more often married and employed. There were more diagnoses of chronic delusional disorder (30%). Persecutory delusion was constant (100%), and the other delusional themes were the \u201cintimate relationship\u201d type (50%)\u2014jealousy, erotomanic\u2014and the bodily type (40%). Additional studies are useful in order to reinforce our findings, and to further investigate the possibilities of prevention.<\/jats:p>","DOI":"10.1111\/1556-4029.14892","type":"journal-article","created":{"date-parts":[[2021,10,15]],"date-time":"2021-10-15T04:01:38Z","timestamp":1634270498000},"page":"265-274","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Homicides committed by delusional patients in the early 20th and 21st centuries: A study conducted in a French secure unit"],"prefix":"10.1111","volume":"67","author":[{"given":"Elo\u00efse","family":"Provoost","sequence":"first","affiliation":[{"name":"UMD Henri Colin GH Paul Guiraud Villejuif France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Raymond","sequence":"additional","affiliation":[{"name":"SMPR La Sant\u00e9 GHU Paris Psychiatrie et Neuroscience Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ivan","family":"Gasman","sequence":"additional","affiliation":[{"name":"UMD Henri Colin GH Paul Guiraud Villejuif France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,10,11]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","first-page":"87","DOI":"10.1176\/appi.books.9780890425596","volume-title":"Diagnostic and statistical manual of mental disorders","author":"American Psychiatric Association","year":"2013"},{"key":"e_1_2_7_3_1","first-page":"83","volume-title":"La folie \u00e0 Paris [Madness in Paris], 1890","author":"Garnier P","year":"2018"},{"key":"e_1_2_7_4_1","first-page":"512","volume-title":"Manuel de psychiatrie [Handbook of psychiatry]","author":"Ey H","year":"1978"},{"key":"e_1_2_7_5_1","first-page":"134","volume-title":"Le d\u00e9lire d\u2019interpr\u00e9tation.
