Late-life depression is a disorder specific to the elderly population with very specific characteristics and prognosis (1, 2). In recent years, depressive disorders have been considered a public health concern due to its high prevalence and wide range of disabilities (3–6) Particularly, evidence from research have reported an association between depressive disorders, cognitive impairment, dementia, and suicide in elderly people. Moreover, research findings support the relationship between depressive disorders, low functionality, and poor quality of life within this population (2, 3, 7–9). Incidence of late-life depression varies across countries. Rates often vary depending on the setting where this syndrome is evaluated. Djernes (10) has reported that in Canadian communities, the recurrence rate of depression in elderly people was <1%, which contrasts from the 42% reported among American nursing home patients. In a survey administered in both urban and rural locations throughout Peru, Mexico, and Venezuela (11), the prevalence of major depressive reported in older adults ranged from 26 to 31%. Lastly, the “Health, Wellbeing, and Aging” survey in Chile (12) found a prevalence of depression at 27% in older adults. Depression among the geriatric population often goes undetected and undiagnosed. The main reason for this pertains to how dissimilar the clinical presentation is in the elderly population compared to the adult population (13–17). This implies that the elderly often do not meet criteria for a diagnosis of major depression. As a consequence, they often do not receive the appropriate or timely health treatment for their symptoms. This is further complicated by the fact that older people diagnosed with depression usually do not use mental health services. According to the Global Action on Aging report (18), only half of the seniors population who are diagnosed with a mental illness receive treatment from health-care services (which is principally primary care), and only a fraction of those actually receive specific interventions from these services. Because older adults typically consult, assist, and prefer primary care; these settings are often the most convenient places to diagnosis and treat late-life depression. However, it is often the case that the health-care staff is not properly trained to treat this population. On the other hand, there is consensus regarding the strategies to properly address late-life depression. According to researchers, first-line treatment for both mild and severe geriatric depression should be a combination of both antidepressants (especially ISRS) and psychotherapy (7, 17, 19) in order to be effective. Recent studies have reported improvement rates with antidepressants to be about 33% responses to treatment varied between 44 and 48% (20, 21). Nevertheless, even though medical treatment contributes significantly to the treatment of depression, only 30–40% of depressed older adults actually adhere to their medication (18). Aside from psychopharmacological treatments, psychological treatments have also proven. In a meta-analysis by Cuijpers et al. (22), results indicated that having at least 6 months of psychotherapy were effective in reducing late-life depression. Specifically, some useful approaches to psychotherapy include cognitive behavioral therapy, life review therapy, and problem-solving therapy. The current implementations of these treatments are far from ideal. This is especially in low-and-middle-income countries (LMICs), where there exists a “gap of treatment” concerning mental health. This refers to the discrepancy between the amounts of people who need healthcare with those who actually receive care (23). The World Health Organization (WHO) has reported that the treatment gap involves 76–90% of adult population in developing countries. Considering the complex and unique characteristics of late-life depression, this gap might be even larger in elderly population. Consequently, collaborative and community care models have been developed to bridge the gaps and to improve the quality of depression care for older people in high-income countries (HICs). These kinds of interventions have been effective in improving treatment adherence and depressive outcomes in HICs (24). These have been particularly constructive for minority populations and individuals living below poverty levels. As such, receiving valuable input and lessons from there members may prove useful for the implementation of future programs in contexts with limited resources.
