Childhood loneliness linked to increased dementia risk

Publicly released:

Frequently feeling lonely as a kid is associated with faster cognitive decline and an increased risk of dementia in adulthood, according to a Chinese study. Researchers looked at memory health and dementia in over 13,000 adults who also shared how lonely they felt both as kids and as adults. The team found this link existed even if participants no longer experienced loneliness as adults. They argue public health initiatives aimed at preventing loneliness should begin in early life.

In this cohort study, childhood loneliness was associated with cognitive decline and dementia risk in middle and later adulthood, even in the absence of adult loneliness. Early interventions aimed at reducing childhood loneliness may help promote lifelong cognitive health and reducing dementia risk.
