A study led by faculty members Martina Luchetti, Ph.D., and Angelina Sutin, Ph.D., alongside their collaborators, has shed new light on the global relationship between loneliness and cognitive decline. This comprehensive research analyzed data from over 20,000 participants across seven countries: the U.S., England, India, China, South Africa, Mexico, and Chile.

Notably, this study underscores that the link between loneliness and cognitive function is not confined to Western cultures. The findings indicate that loneliness impacts cognitive health across a broad spectrum of global populations.
