Background and Purpose: The elderly living alone feel lonelier and more isolated than do those live with others, and they are at higher risk for cognitive decline and depression. This study aimed to assess whether a home-visiting cognitive intervention (HCI) can have positive effects on cognitive improvement for the elderly who living alone. Methods: HCI was conducted from April 2016 to November 2019. Every elder who lived alone and 2 matched partners met for 8 weeks once a week. The partners visited participants' home and did the HCI which composed of cognitive training and cognitive stimulation activities. The Mini-Mental State Examination-dementia screening (MMSE), Geriatric Depression Scale (GDS), the Korean version of instrumental activities of daily living (K-IADL), and the Social Support Scale (SSS) were evaluated before and after HCI to compare the effect of HCI. Results: A total of 258 participants showed significant improvements in MMSE, GDS, K-IADL, and SSS. The MMSE and GDS scores were significantly improved after HCI in both the normal cognition (NC, n=210) and cognitive impairment (CI, n=48) groups. The cognitive effect of HCI for CI was higher than for NC. Among the NC, the magnitude of cognitive improvement was greater in the higher educated group (above 7 years) than in the other groups. Conclusions: Active cognitive interventions could provide possible benefits to improve cognition, emotion, and functional abilities. Regular cognitive-care services like HCI are necessary to reduce dementia risk for the elderly who live alone in the community.
