This study investigated suicide risk in older adults within 1 year of receiving a diagnosis of dementia. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> This study used National Health Insurance Service Senior Cohort data and included 36 541 older adults with newly diagnosed dementia (a Mini-Mental State Examination score \u2264 26 and a Clinical Dementia Rating score \u2265 1 or a Global Deterioration Scale score \u2265 3), including Alzheimer disease, vascular dementia and other\/unspecified dementia, from 2004 to 2012. We selected older adults without dementia through 1:1 propensity-score matching using sex, age, comorbidities and index year, with follow-up throughout 2013. We estimated adjusted hazard ratios (AHRs) of suicide deaths within 1 year after diagnosis using a time-dependent Cox proportional hazards model. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> We verified 46 suicide deaths during the first year after a dementia diagnosis. Older adults with dementia had an increased risk of suicide death compared to those without dementia (AHR 2.57; 95% confidence interval [CI] 1.49\u20134.44). Older adults with Alzheimer disease (AHR 2.50; 95% CI 1.41\u20134.44) or other\/unspecified dementia (AHR 4.32; 95% CI 2.04\u20139.15) had an increased risk of suicide death compared to those without dementia. Patients with dementia but without other mental disorders (AHR 1.96; 95% CI 1.02\u20133.77) and patients with dementia and other mental disorders (AHR 3.22; 95% CI 1.78\u20135.83) had an increased risk of suicide death compared to patients without dementia. Patients with dementia and schizophrenia (AHR 8.73; 95% CI 2.57\u201329.71), mood disorders (AHR 2.84; 95% CI 1.23\u20136.53) or anxiety or somatoform disorders (AHR 3.53; 95% CI 1.73\u20137.21), respectively, had an increased risk of suicide death compared to patients with those conditions but without dementia. <\/jats:p><\/jats:sec><jats:sec><jats:title>Limitations<\/jats:title><jats:p> This study examined only elderly patients in South Korea, a population with a substantially higher suicide rate than the global population.
