An JH, et al. - In this cohort study, researchers evaluated suicide and accidental death rates among patients in whom cognitive impairment was diagnosed based on a clinical case registry. The study sample consisted of 10,169 subjects with dementia or mild cognitive impairment (MCI) who were evaluated from January 2005 to December 2013 at the Clinical Research Center for Dementia of Korea (CREDOS). Findings suggested that the risk of suicide death has not increased among people with cognitive impairment whereas the risk of accidental death has increased significantly. Preventive strategies should be implemented from the early stages for premature mortality in those with cognitive impairment and should include careful assessment of individual risk factors for each type of death.
