OBJECTIVE: Executive deficits may play an important role in late-life suicide. Yet, current evidence in this area is inconclusive and does not indicate whether these deficits are broadly associated with suicidal ideation or are specific to suicidal behavior. This study examined global cognition and specifically executive function impairments as correlates of suicidal ideation and suicidal behavior in depressed older adults, with the goal of extending an earlier preliminary study. DESIGN: Case-control study. SETTING: University-affiliated psychiatric hospital. PARTICIPANTS: All participants were age 60+: 83 depressed suicide attempters, 43 depressed individuals having suicidal ideation with a specific plan, 54 nonsuicidal depressed participants, and 48 older adults with no history of psychiatric disorders. MEASUREMENTS: Global cognitive function was assessed with Dementia Rating Scale (DRS) and executive function with Executive Interview (EXIT). RESULTS: Both suicide attempters and suicide ideators performed worse than the two comparison groups on the EXIT, with no difference between suicide attempters and suicide ideators. On the DRS total score, as well as on Memory and Attention subscales, suicide attempters and ideators and nonsuicidal depressed subjects performed similarly and were impaired relative to nonpsychiatric control subjects. Controlling for education, substance use disorders, and medication exposure did not affect group differences in performance on either the EXIT or the DRS. CONCLUSIONS: Executive deficits, captured with a brief instrument, are associated broadly with suicidal ideation in older depressed adults but do not appear to directly facilitate suicidal behavior. Our data are consistent with the idea that different vulnerabilities may operate at different stages in the suicidal process.
