Suicidal behavior in the nursing home and a postsuicide intervention

Accelerated brain aging predicts impulsivity and symptom severity in depression

Multiple structural and functional neuroimaging measures vary over the course of the lifespan and can be used to predict chronological age. Accelerated brain aging, as quantified by deviations in the MRI-based predicted age with respect to chronological age, is associated with risk for neurodegenerative conditions, bipolar disorder, and mortality. Whether age-related changes in resting-state functional connectivity are accelerated in major depressive disorder (MDD) is unknown, and, if so, it is unclear if these changes contribute to specific cognitive weaknesses that often occur in MDD. Here, we delineated age-related functional connectivity changes in a large sample of normal control subjects and tested whether brain aging is accelerated in MDD. Furthermore, we tested whether accelerated brain aging predicts individual differences in cognitive function. We trained a support vector regression model predicting age using resting-state functional connectivity in 710 healthy adults aged 18-89. We applied this model trained on normal aging subjects to a sample of actively depressed MDD participants (n = 109). The difference between predicted brain age and chronological age was 2.11 years greater (p = 0.015) in MDD patients compared to control participants. An older MDD brain age was significantly associated with increased impulsivity and, in males, increased depressive severity. Unexpectedly, accelerated brain aging was also associated with increased placebo response in a sham-controlled trial of high-frequency repetitive transcranial magnetic stimulation targeting the dorsomedial prefrontal cortex. Our results indicate that MDD is associated with accelerated brain aging, and that accelerated aging is selectively associated with greater impulsivity and depression severity.

Preventing Suicide and Depression: A Training Program for Long-Term Care Staff

Approximately 5 percent of those sixty-five and older live in long-term care facilities (1.5 million). Neither suicide and depression among the elderly who reside in long-term care facilities nor prevention techniques are well-understood by staff. This article discusses the development of a curriculum designed to train long-term care staff in preventing suicide among the elderly and the results of a pilot test of a training program based on that curriculum. The participants ( N=43) significantly improved their scores from pre- to post-test on the knowledge, attitudes, and practices subtests. The knowledge areas in which staff performed the most poorly at pre-test were related to identifying appropriate primary and secondary interventions, the relationship between dementia and suicide, methods of self-destruction used by the elderly, and understanding of depression in the elderly. There was a significant relationship between pre-test and post-test scores on all subtests. Staff with higher levels of education had significantly higher pre- and post-test scores on the knowledge and attitudes subtests. More experienced staff had significantly higher post-test scores on the practices subtest. A large majority of the participants had highly positive attitudes toward the program and thought the program had been very useful or useful to them as caregivers. The study demonstrated the need for staff training related to suicide prevention in long-term care as well as the usefulness of even a brief training.

Survivors of Suicide: A Comprehensive Bibliography Update, 1986–1995

An update of a 1985–86 Omega bibliography of the literature on survivors of suicide is presented. Following brief introductory comments, including the identification of research and therapy needs and unresolved issues, the bibliography listings are organized by the following subtopics: general references on family members and friends as suicide survivors; children, adolescents, youth, and parents as survivors; school and educational settings; parental suicide; elderly suicide survivors; mental health professionals and clinicians in training as survivors; survivors of professionals' suicides; and research on attitudes toward survivors. Published works in professional journals, books, book chapters, and doctoral dissertations on the topic of survivor-victims are included.

Suicide in elderly South Tyroleans in various residential settings at the time of death: a psychological autopsy study

BACKGROUND

Completed suicide is more frequent among older adults than any other age group. Data on suicide in nursing homes and other residential facilities are inconsistent. This work aims to describe the characteristics of elderly suicide victims in different residential settings compared to young suicide victims.

METHODS

Data on people who died by suicide in the South Tyrol (Alto Adige) region of Italy between 2000 and 2009 were gathered from the local Provincial Mortality Register. Further detailed information was collected via questionnaires to mental health departments and psychological services, family physicians and relatives of the deceased.

RESULTS

A total of 525 cases of suicide were recorded, with a linearly decreasing trend during the study period. About one-third of the suicides occurred in those aged 60 years and over. Suicide in the elderly was associated with low education level (odds ratio (OR) = 7.1, P < 0.001), living in a one-person household (OR = 2.4, P < 0.01), not having economic troubles (OR = 6.1, P < 0.01), having seen a doctor in the past month (OR = 2.4, P < 0.01) and living in a residential facility (OR = 2.6, P < 0.05). Twenty-four (17.9%) suicide victims aged 60 years and over were in a residential facility/hospital at the time of the death. They were more likely to be women, not married, and to die by jumping from a height.

CONCLUSIONS

The suicide risk should be carefully assessed in the elderly who live alone or are institutionalized or hospitalized. Efforts are warranted to reduce seniors' access to high places in hospitals and facilities.

Impulsivity and hopelessness as predictors of suicide-related ideation among older adults

OBJECTIVE

Research has demonstrated that impulsivity is strongly associated with suicide-related ideation and behaviour among young adults. However, to date, the potential importance of impulsivity as a predictor of suicide-related ideation in later life has yet to be determined. Our study examined impulsivity, hopelessness, depressive symptomatology, and sociodemographic factors vis-à-vis suicide-related ideation among older adults at risk of self-harm.

METHOD

A sample (n = 117) of older adults was recruited from multiple sources for this study over a 1-year period. Suicide-related ideation was measured with the Geriatric Suicide Ideation Scale, a multidimensional measure of suicide-related ideation developed for use with older adults.

RESULTS

Canonical correlation identified 2 pairings of linear composites in which impulsivity emerged along both as significantly associated with facets of suicide-related ideation. Of note, the greater proportion of variance in impulsivity was subsumed along the second set of vectors with somatic depressive symptoms.

CONCLUSION

Our findings suggest that the impulse to self-harm may be even more pronounced among older adults less likely to present as typically depressed. It is further suggested that impulsivity is more broadly associated with suicide-related ideation than hopelessness, and that screening for impulsivity as well as hopelessness may increase clinicians' ability to identify older adults at greatest risk of self-harm.

Suicide and the elderly

Impending demographic changes mean that the proportion of the elderly in the population will increase. Suicide rates increase with age. The literature on elderly suicide, with emphasis on methodology, cross-national rates and trends, correlates, cultural factors, location and method, attempted suicides and prevention, is critically reviewed in this paper.
