However, there are few data on the prevalence after transient ischemic attack (TIA), and it is unclear whether TIA can trigger depression and, if so, what factors might suggest susceptibility in an individual.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We completed a systematic review (Medline\/PsycINFO\/EMBASE searched to 20 March 2025) of published cross-sectional or cohort studies that reported the prevalence of depression at any time point after a TIA and validated the findings in a population-based cohort (Oxford Vascular Study; OXVASC).

However, among studies with serial assessments (196 patients from four published longitudinal studies and 478 from OXVASC) there was less heterogeneity and the pooled prevalence of depression fell from 20.1% (16.9%\u201323.4%;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      <jats:sub>het<\/jats:sub>\n                      \u2009=\u20090.35) at 0\u20131\u2009month to 14.1% (11.5%\u201316.7%;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      <jats:sub>het<\/jats:sub>\n                      \u2009=\u20090.40) at 3\u201312\u2009months (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      <jats:sub>diff<\/jats:sub>\n                      \u2009=\u20090.004). In the few studies that reported risk factors for depression after a TIA, younger age was the only consistent predictor, but this was similarly validated in the OXVASC population. On regression analysis for heterogeneity, 83% of the variance in prevalence rates between studies was explained by assessment method (postal questionnaire: 5.6%, 95% CI 3.1\u20138.1 vs face-to-face interview 17.7%, 13.7\u201321.7;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.001), the screening tool used, TIA definition and exclusion criteria. A model, based on these study methods in published studies, predicted a prevalence rate of 22.1% in OXVASC, which was close to the observed rate of 20.7% at 1\u2009month validating the findings.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Depression affects about 1-in-5 patients early after a TIA but prevalence falls with time, suggesting that it may be triggered by the event in some cases, but further work is required to identify risk factors. In addition, when planning future research, investigators must remain cognizant of the significant influence that study design has on the observed prevalence rates.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17474930261432616","type":"journal-article","created":{"date-parts":[[2026,3,11]],"date-time":"2026-03-11T10:15:32Z","timestamp":1773224132000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Prevalence, time-course and predictors of depression after transient ischemic attack: A systematic review, meta-analysis, and validation"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5426-5344","authenticated-orcid":false,"given":"Aubretia J","family":"McColl","sequence":"first","affiliation":[{"name":"Wolfson Centre for the Prevention of Stroke and Dementia, Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Pendlebury","sequence":"additional","affiliation":[{"name":"Wolfson Centre for the Prevention of Stroke and Dementia, Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter M","family":"Rothwell","sequence":"additional","affiliation":[{"name":"Wolfson Centre for the Prevention of Stroke and Dementia, Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,3,3]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.bp.111.107664"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.2015.15030363"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/ene.12469"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-021-10597-4"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(24)01296-0"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.160.14.2101"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.bp.114.153494"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.2013.13030325"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jstrokecerebrovasdis.2017.07.006"},{"key":"e_1_3_3_11_2","doi-asserted-by":"crossref","unstructured":"McColl A Rothwell P Pendlebury S.
