This study aimed to identify the specific cognitive domains associated with passive suicidal ideation (e.g. thoughts of being better off dead). A cross sectional, national based study of 1,712 individuals over the age of 50. Outcome measure, passive suicidal ideation, was evaluated by the question, in the past month, have you felt that you would rather be dead?, taken from the Euro-D. Cognitive domains assessed were time orientation, verbal learning, verbal recall, word fluency, and arithmetic. After adjusting for demographic and clinical information, those reporting passive suicidal ideation were significantly more likely to have impaired performance on the time orientation task. None of the other cognitive domains were associated with passive suicidal ideation. Clinicians working with older adults need to be aware not only of demographic and clinical information, but also of cognitive functioning and more specifically, time orientation, as a potential determinant of passive suicidal ideation. Possibly, cognitive domains that are less affected by education and prior learning (e.g. time orientation) have a unique association with passive suicidal ideation.

Cognitive functioning has been identified as a predictor of all cause mortality in several epidemiological studies. As a result, researchers have suggested the use of short cognitive screens as prognostic indicators in older adults. Little is known, however, about subjective complaints of cognitive functioning as predictors of all cause mortality. A 7-year follow-up of a national sample of 4,921 Israelis over the age of 60. Main predictors were subjective complaints of memory problems, confusion, and recognition problems. Outcome was time to death. As expected, in the fully adjusted model, age, gender, subjective health, baseline health, and ADL and IADL impairments were significant predictors of all cause mortality. In addition, complaints about difficulties recognizing familiar people also were associated with a greater risk for mortality. Subjective complaints about recognition problems serve as a risk for all cause mortality above and beyond well-known risk factors. Health care professionals can use this information about subjective cognitive functioning in conjunction with other measures in order to identify older adults at risk for an earlier death.
