Continuing advances in antiretroviral therapy are increasing survival and longevity for people living with HIV. However, factors related to depression and suicidal ideation associated with aging and HIV may mean that the synergistic effects of aging with HIV could place many adults at undue risk for these conditions. Such factors include ageism and stigma, loneliness/decreased social support, neurological changes, declining health, fatigue, changes in appearance, and financial distress. Potential interventions that address these factors are needed to abate depression and prevent suicidal ideation. Nurses are in key positions to identify and intervene with HIV-infected and aging patients who may be at risk for depression and suicidal ideation. © 2008 Association of Nurses in AIDS Care.
