The COVID-19 pandemic entailed restrictions that hampered face-to-face interactions and social gatherings. In this paper, we examine whether loneliness increased to different extents among age groups due to these restrictions, and if these differences were mediated by specific life course conditions. Based on longitudinal data from the Swiss Household Panel, our results show that loneliness increased disproportionately among younger individuals during the pandemic. This finding aligns with the social convoy model and the socioemotional selectivity theory, which postulate a decline of social network size over the life course. It also corresponds to findings indicating a decrease in contact frequency with increasing age. Individuals aged 30 years and above experienced a lower increase in loneliness when they lived in shared households; however, this protective effect was not observed for younger individuals. Living together with a partner, being male, and not anticipating health complications in case of a COVID-19 infection moderated the increases of loneliness, but they were independent of age.

Background: Gut microbiota modulation of the brain function may present an opportunity to devise preventive or treatment strategies to manage impairments such as cognitive frailty (CF). This study aims to uncover the relationship between CF, gut microbiota, intestinal permeability and proteome.
Method: A total of 137 fecal samples of the elderly were collected, and subjected to DNA analysis, and enzyme-linked immunosorbent assays (ELISA).

Background: Loneliness has been linked to cognitive decline and an elevated risk of Alzheimer's disease (AD). Previous studies measured loneliness at a single point time, which may not accurately capture the longitudinal changes of different loneliness types (e.g.

Background: Loneliness and depression among older adults are linked to a higher likelihood of chronic diseases, deterioration of physical function, and compromised quality of life. LGBTQ older adults are known to experience social isolation and mental distress at higher rates than their heterosexual counterparts, and those with cognitive impairment may be particularly susceptible to loneliness and depression. However, there is limited knowledge regarding the risk and protective factors for loneliness and depression among LGBTQ older adults living with cognitive impairment.

Background: The effects of the COVID-19 pandemic extend beyond the viral impact and include social and psychological effects of the ensuing lockdowns and restrictions. Australia's lengthy lockdowns present an opportunity to study changes in the physical and mental wellbeing of older adults resulting from extended social isolation, a known risk factor for dementia, in the absence of high infection or mortality rates.
Method: Sydney Memory and Ageing Study, Sydney Centenarian Study, and CogSCAN study participants were mailed questionnaires about in-person and remote social contact and access to resources during the 2020 Sydney lockdown.

Background: Loneliness, dementia, and mortality are interconnected. Thus, understanding the pathways, along with their potential interaction provides a relevant area of research to be developed.
Method: The study tested bi-directional relationships between dementia, loneliness and mortality, while examining both interactions and mediating effects in a large sample of older US adults participating in the nationally representative Health and Retirement Study.
