COVID‐19‐related loneliness, social isolation and burden in informal caregivers worldwide

Informal caregivers may experience high levels burden. Prior to COVID‐19, loneliness and social isolation, and especially the discordance between them, were recognized for rapid aging‐related cognitive decline. The COVID‐19 has significantly increased social isolation and loneliness in caregivers. Thus, we aimed to explore the variables that were associated with higher care burden among all caregivers and only among caregivers for people living with dementia, and whether the increased burden could be associated with a discrepancy between loneliness and social isolation.
