Staying socially connected may be one of the most effective ways to protect brain health after leaving the workforce, according to a new study led by researchers at the International Institute for Applied Systems Analysis (IIASA). Drawing on data from more than 145,000 observations across 27 European countries, the researchers found that strong social networks can help offset the loss of mentally stimulating interactions that often come with retirement or other forms of non-employment. The findings also reveal that men and women benefit from different types of social relationships, highlighting the need for tailored approaches to healthy ageing.
As Europe’s population continues to age, preserving cognitive health has become an increasingly important public health priority. Previous studies have shown that both employment and social engagement contribute to better mental functioning. Still, little research has examined how these factors work together or whether their effects differ between men and women. To address this gap, the researchers analysed data from adults aged 50 and older who participated in the Survey of Health, Ageing and Retirement in Europe (SHARE) between 2011 and 2020. Participants included those who were employed, retired, unemployed, or homemakers.
The research focused on two important measures of cognitive health: episodic memory, which involves recalling past experiences and information, and verbal fluency, or the ability to generate words quickly. Researchers then examined how different levels of social connectedness influenced cognitive performance among people with different employment statuses. The results showed that social relationships can provide valuable mental stimulation, especially for individuals who are no longer working.
The study also uncovered important gender differences. Among women, having a broad and diverse social network appeared to compensate for the cognitive stimulation that employment often provides. Women who maintained connections with family members, friends, neighbours, and community groups generally performed better on cognitive tests after leaving the workforce. For men, however, the quality of close personal relationships appeared to matter more than the size of their social circle. Strong bonds with a spouse or partner were particularly important, while men with few or no social connections experienced significantly poorer episodic memory, underscoring the risks associated with social isolation.
These findings have important implications for policymakers and healthcare professionals seeking to promote healthy ageing. Rather than adopting a one-size-fits-all approach, programmes designed to support older adults should recognise that men and women may benefit from different forms of social engagement. Encouraging older women to maintain diverse social networks and helping older men build and preserve close personal relationships could both play a meaningful role in protecting cognitive health. Preventing loneliness and social isolation should therefore be considered a key component of public health strategies in ageing societies.
The researchers conclude that social networks can serve as an important source of cognitive stimulation when employment is no longer part of daily life. While retirement often marks the end of regular workplace interactions, maintaining meaningful social connections may help preserve memory, communication skills, and overall cognitive resilience. As populations continue to age around the world, fostering stronger social relationships may prove just as valuable as promoting physical health in helping older adults enjoy fulfilling, independent lives.
