Older Women’s Loneliness and Depression Decreased by a Reminiscence Program in Times of COVID-19

The confinement caused by the current COVID-19 pandemic protects physical health, but in turn, has a long-lasting and far-reaching negative psychosocial impact; anxiety, stress, fear and depressive symptoms. All of these have a particular impact on vulnerable older people, putting them at serious risk of loneliness. Women report feeling lonelier than men, affecting women to a greater extent. The present study aims to analyze the efficacy of an integrative reminiscence intervention in older women living in nursing homes to reduce the effects of loneliness and depression after COVID-19. 34 older women living in nursing homes are included into study and were divided into intervention group (N = 14) and control group (N = 20). Results showed a significant reduction in perception of loneliness, depression and better positive affects, after the intervention. The pandemic has not yet finished and the most affected group has been the people living in nursing homes. These results show the need for evidence of interventions that can help the recovery of these people who have been so affected. The effects of loneliness during confinement and its psychological effects can be mitigated through such programs.

“…61 Hanaoka et al reported that olfactory stimulation for reminiscence practice, which is the volitional or non-volitional act or process of recollecting memories of individual episodes, was a useful intervention for maintaining mental health, although the effect of reminiscence on cognitive function was not shown in this study because of the ceiling effect of the Mini-Mental State Examination and the time-dependent manner reported previously. 62,63 In mild cognitive impairment and early dementia, cognitive function and psychiatric symptoms, such as motivation and depression, which are associated with frontal lobe function, often interact and accompany mutually. A recent study in rats showed that formation of permanent memories over time required the generation of new prefrontal engram cells that are formed at the same time as the initial memory cells in the hippocampus, as well as neuronal connections in the cerebral cortex, particularly the prefrontal cortex.…”

Geriatric syndromes are symptoms and signs, such as falls, incontinence, delirium, pressure ulcers, dysphagia and so on, that often threaten the independence of older adults, rather than the disease itself. Although the syndromes are very common in older people, it is difficult to treat those by modern medicine due to their complexity. To mitigate the intractable geriatric symptoms, we review the efficacy of aromatherapy, especially for dysphagia, dyspnea, cognitive dysfunction and falls in geriatric syndrome. Olfactory stimulation using a volatile black pepper oil on institutional residents improved the swallowing reflex, which is a crucial risk factor of aspiration pneumonia. Brain imaging study showed that olfactory stimulation using volatile black pepper oil activated cerebral regions of the anterior cingulate and the insular cortex, which play a role in controlling appetite and swallowing. Also, aromatherapy with volatile l-menthol decreased the sense of dyspnea and improved the efficacy of exercise therapy. The fragrance of the combination of rosemary and lemon oils in the morning, and the combination of lavender and orange oils in the night-time were reported to improve cognition and behavioural and psychological symptoms of dementia, respectively. Also, the combination of lavender and lemon balm oils was reported to be effective for irritability-related agitation in older adults. Furthermore, aromatherapy with lavender fragrance could improve both static and dynamic balance, resulting in a reduction in the number of fallers and the incidence rate in older people. Thus, aromatherapy is a promising remedy for geriatric syndrome.

“…At this moment, whether the neural correlates of nostalgia differ depending on the memory content (e.g., people, object, and places) and memory type (e.g., episodic and semantic AM) is still not fully understood. Investigation of the mechanisms underlying individual differences in nostalgia functions would provide neuroscientific evidence for applications, especially in clinical settings such as reminiscence therapy for individuals with dementia (Hanaoka et al, 2018;Istvandity, 2017;Yasuda et al, 2009), depression (Hsieh & Wang, 2003), or terminal illness (Wholihan, 1992). Because the neuroimaging studies have largely focused on young populations, it is also important to validate the multilevel memory-reward coactivation framework in elderly people.…”

Nostalgia, a sentimental longing for the past, has attracted attention in the fields of psychology and marketing in recent years. Although these studies have identified what nostalgia is, including its triggers and functions, the question of how nostalgia is induced remains unanswered. In this article, we review existing psychological models and recent neuroimaging studies that have investigated the neural correlates of nostalgia and propose a provisional framework of nostalgia induction. The multilevel memory‒reward coactivation framework expects that different types of autobiographical memory (AM), such as episodic AM and semantic AM, activate the associated mesolimbic reward system. This framework also assumes a working self, a complex set of active goals and associated self-images, which enables us to explain individual differences in nostalgia experience by influencing what is remembered and how the retrieved information is evaluated. This framework is advantageous in that it can integrate existing psychological models into one model and can explain individual differences in nostalgia that are important for the use of nostalgia, especially in clinical situations.
