The Interpersonal Context of Suicide and Self-Harm in Later Life: An Invited Commentary on "Why Do the Very Old Self-Harm? A Qualitative Study"

Static and dynamic functional connectivity of the habenula in late-life depression patient with suicidal ideation

BACKGROUND

Suicide is one of the most lethal complications of late-life depression (LLD), and habenular dysfunction may be involved in depression-related suicidality and may serve as a potential target for alleviating suicidal ideation. This study aimed to investigate abnormal functional connectivity of the habenula in LLD patients with suicidal ideation.

METHODS

One hundred twenty-seven patients with LLD (51 with suicidal ideation (LLD-S) and 76 without suicidal ideation (LLD-NS)) and 75 healthy controls (HCs) were recruited. The static functional connectivity (sFC) and dynamic functional connectivity (dFC) between the habenula and the whole brain were compared among the three groups, and correlation and moderation analyses were applied to investigate whether suicidal ideation moderated the relationships of habenular FC with depressive symptoms and cognitive impairment.

RESULTS

The dFC between the right habenula and the left orbitofrontal cortex (OFC) increased in the following order: LLD-S > LLD-NS > control. No significant difference in the habenular sFC was found among the LLD-S, LLD-NS and control groups. The dFC between the right habenula and the left OFC was positively associated with global cognitive function and visuospatial skills, and the association between this dFC and visuospatial skills was moderated by suicidal ideation in patients with LLD.

CONCLUSION

The increased variability in dFC between the right habenula and left OFC was more pronounced in the LLD-S group than in the LLD-NS group, and the association between habenular-OFC dFC and visuospatial skills was moderated by suicidal ideation in patients with LLD.

Self-harm in the very old one year later: has anything changed?

OBJECTIVES

To follow-up a cohort of older people who self-harmed, their carer, and general practitioner (GP) and examine their reflections on the self-harm, care experiences, and outcomes.

DESIGN

Qualitative in-depth interviews.

SETTING

Two teaching hospitals and associated community services.

PARTICIPANTS

Twelve-month follow-up of participants aged 80 or older who self-harmed, their nominated carers, and GPs.

MEASUREMENTS

A geriatric psychiatrist gathered data through patient and carer interviews using a narrative inquiry approach and from medical records. Interviews were audio recorded and transcribed. N-VIVO facilitated data organization for thematic analysis. Questionnaires sent to the patient's GP examined their perspectives and aspects of care relating to the self-harm.

RESULTS

Nineteen patients (63% baseline sample), 29 carers (90.6%), and 11 GPs (36.7%) were available at follow-up. Themes emerging from patients were "denial and secrets;" "endless suffering;" "more invalidation;" "being heard;" and "miserable in care." Themes from carer interviews were "denial and secrets;" "patient's persistent wish to die;" "abandonment by clinicians;" "unending burden for the carer;" and "distress regarding placement." General practitioner themes were "the problem is fixed;" "the troops have arrived;" and "I understand."

CONCLUSIONS

Factors contributing to self-harm persisted at follow-up. Positive and negative responses were identified in the older person's system, highlighting areas for potential intervention. A conceptual framework for understanding self-harm in the very old was derived that emphasized the importance of understanding individual needs, the interpersonal context of the older person, and carer burden. Interventions should improve communication, facilitate shared understanding of perspectives, and provide support at all levels.
