[Epidemiological Findings on the Influence of Social Isolation and Loneliness on Dementia Risk].

Abstract

As Japan is becoming a super-aged society, addressing the rising prevalence of dementia has become an urgent public health priority. Epidemiological studies, both domestic and international, have identified social isolation and loneliness as significant risk factors for dementia onset. Long-term reductions in cognitive stimulation due to social isolation and persistent subjective feelings of disconnection are associated with an increased risk of dementia. Therefore, providing social support to older adults and mitigating loneliness are essential measures to reduce the risk of dementia.
