Social concepts such as loneliness and social isolation are fairly new factors that have been recently gaining attention to their involvement in changes cognitive function association with dementia. The primary aim of this narrative review was describe the current understanding how influence aging they linked Studies shown there is an between loneliness, isolation, reduced function, older adults, across multiple domains, well a heightened risk Numerous underlying neural biomechanisms including cortisol secretion brain volume alterations (e.g., white/grey matter, hippocampus) may contribute these relationships. However, due poor quality research, mixed inconclusive findings, issues accurately defining measuring more consistent high-quality interventions needed determine whether studies addressing can impact longer term This especially important given long-term COVID-19 pandemic on people yet be fully understood.

BackgroundAlthough the long-term health effects of COVID-19 are increasingly recognised, societal restrictions during pandemic hold potential for considerable detriment to cognitive and mental health, particularly because major dementia risk factors—such as those related exercise dietary habits—were affected this period. We used longitudinal data from PROTECT study evaluate effect on cognition in older adults UK.MethodsFor analysis, we computerised neuropsychology individuals aged 50 years participating UK. Data were collected same participants before (March 1, 2019–Feb 29, 2020) its first 2020–Feb 28, 2021) second 2021–Feb 2022) years. compared across three time periods using a linear mixed-effects model. Subgroup analyses conducted people with mild impairment who reported history COVID-19, an exploratory regression analysis identified factors associated changes trajectory.FindingsPre-pandemic included 3142 participants, whom 1696 (54·0%) women 1446 (46·0%) men, mean age 67·5 (SD 9·6, range 50–96).

Loneliness and social isolation can occur at any stage of life, but some predictors may be more common among older adults. Due to growing population ageing, loneliness are relevant issues.
