Whereas perinatal depression is well documented, there is still little research on the full range of perinatal psychiatric disorders and their clinical evolution across this whole period. The present study investigated the susceptibility to psychiatric illness during pregnancy and up to one year postpartum. We aimed to identify the most frequent disorders and comorbidities arising in each perinatal period. We outlined the clinical trajectories of these disorders in terms of evolution across past history, pregnancy and postpartum.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>Through a retrospective longitudinal design, data were collected in 2019\u20132020 from the medical records of the cohort of 964 women who required care in a tertiary perinatal psychiatry clinic located in Quebec City (Canada) between 2004 and 2020.

For most disorders, rates were significantly higher in postpartum than in pregnancy. A woman could develop multiple disorders during a given perinatal period: this comorbidity involved various combinations of diagnoses in 28% of women during pregnancy and 38% during postpartum. We outlined 52 different clinical trajectories from past history to postpartum, underlining the heterogeneity of the perinatal course.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Pregnancy is a susceptible period for women with past psychiatric histories whereas postpartum could trigger a new illness in women without a past history or pregnancy-onset psychiatric disorder.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/07067437251328347","type":"journal-article","created":{"date-parts":[[2025,6,24]],"date-time":"2025-06-24T00:13:51Z","timestamp":1750724031000},"page":"499-510","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["The Complex Journey of Women in Perinatal Psychiatric Care: Susceptibility to Illness Onset, Comorbidity and Clinical Trajectories: Le parcours complexe des femmes en psychiatrie p\u00e9rinatale : vuln\u00e9rabilit\u00e9, comorbidit\u00e9s et trajectoires cliniques"],"prefix":"10.1177","volume":"70","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7341-0545","authenticated-orcid":false,"given":"Alexandra","family":"Painchaud","sequence":"first","affiliation":[{"name":"Centre de recherche CERVO, Qu\u00e9bec City, QC, Canada"},{"name":"Universit\u00e9 Laval"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie-Jos\u00e9e","family":"Poulin","sequence":"additional","affiliation":[{"name":"Centre de recherche CERVO, Qu\u00e9bec City, QC, Canada"},{"name":"Institut universitaire en sant\u00e9 mentale de Qu\u00e9bec"},{"name":"Universit\u00e9 Laval"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5999-2129","authenticated-orcid":false,"given":"C\u00e9lia","family":"Matte-Gagn\u00e9","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Laval"},{"name":"Groupe de recherche sur l\u2019inadaptation psychosociale chez l\u2019enfant (GRIP), Quebec City, QC, Canada"},{"name":"Centre de recherche universitaire sur les jeunes et les familles (CRUJeF), Quebec City, QC, Canada"},{"name":"Universit\u00e9 Laval"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4033-0576","authenticated-orcid":false,"given":"Chantal","family":"M\u00e9rette","sequence":"additional","affiliation":[{"name":"Centre de recherche CERVO, Qu\u00e9bec City, QC, Canada"},{"name":"Universit\u00e9 Laval"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,4,16]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00737-013-0408-1"},{"key":"e_1_3_2_3_2","first-page":"207","volume-title":"Biomarkers of postpartum psychiatric disorders","author":"Osborne LM","year":"2019","unstructured":"Osborne LM, Payne JL.
