P.322 Progression of dopaminergic and serotonergic dysfunction related to neuropsychiatric signs in Parkinson's disease
European Neuropsychopharmacology(2020)
摘要
Evidence shows that schizophrenia is associated with increased incidence of stroke. However, relationship between schizophrenia and short-term mortality risk is understudied, and mixed findings were observed. In this retrospective population-based cohort study, we identified individuals admitted for incident ischemic stroke between 2006 and 2016 using a territory-wide electronic medical record database of public healthcare system in Hong Kong to examine 30-day and 1-year mortality rates in 817 schizophrenia patients compared with 8170 patients without psychotic disorder (10:1 matched to schizophrenia patients on demographics, treatment sites and calendar-period for index admission). Multivariate regression analyses adjusting for medical comorbidities revealed that schizophrenia patients experienced elevated 1-year (16.9% vs 12.1%; p < 0.001) and 30-day mortality (7.2% vs 5.3%; p = 0.053) relative to control group. Additional age- and gender-stratified analyses revealed even more pronounced effect of schizophrenia on raised mortality risk, as indicated by higher odds, in younger-age (<65 years) group and men. Our results indicate that schizophrenia is associated with heightened short-term mortality following incident ischemic stroke. Further research is warranted to identify factors contributing to excess post-stroke deaths among schizophrenia patients to facilitate development of effective interventions for mortality risk reduction.
