A new study published in the Proceedings of the National Academy of Sciences suggests that having children may enhance brain function and combat aging. Involving 37,000 adults, it is the largest investigation into parental brain health, showing that parenting offers cognitive stimulation, social interaction, and physical activity. The research revealed that more children correlate with increased brain connectivity, particularly related to movement and sensory functions. Notably, both mothers and fathers benefit, challenging the belief that parenting is detrimental to mental health. However, researchers call for further studies globally to solidify these findings and understand parenting’s role in reducing dementia risks.
A new study published in the Proceedings of the National Academy of Sciences (PNAS) suggests that having children may enhance brain fitness and maintain a youthful state. This research, which encompasses 37,000 adults, is noted as the most extensive study of parental brain function to date.
The findings indicate that, despite the fatigue and stress that come with parenting, raising children can enrich an individual’s life over time by providing essential cognitive stimulation, physical activity, and social engagement.
“Our findings show that parenting multiple children is associated with increased brain-wide functional connectivity, particularly in networks related to movement and sensation,” the research states.
While many studies on parenthood often exclude fathers since they do not physically undergo pregnancy, the current study included over 17,000 men. The results indicated that even though fathers are not actively involved in the pregnancy process, the birth and upbringing of a child have a significant impact on their brain health.
“These networks also demonstrated reduced functional connectivity with advancing age, suggesting that parenthood may serve as a protective factor against functional brain aging. This phenomenon is observed in both men and women, highlighting the importance of the caregiving environment beyond pregnancy alone.”

‘The more the merrier’
Furthermore, it appears that having more children correlates with enhanced benefits, according to Avram Holmes, a psychiatry professor at the Rutgers Center for Advanced Human Brain Imaging Research and the study’s lead author.
“We’re identifying a consistent pattern of functional changes, where a greater number of children is linked to heightened functional connectivity, particularly in areas of the brain associated with movement, sensation, and social interaction,” stated Mr. Holmes.
This study challenges the conventional notion that raising children is solely overwhelming and detrimental to mental capacity. However, the researchers noted that since the participants were primarily from the UK, additional insights from diverse populations worldwide are necessary for conclusive findings.
They emphasized the need for further research to explore how parenting can mitigate brain aging. The outcomes could be significant, assisting scientists in addressing issues related to loneliness and dementia in an aging demographic, especially as fewer individuals are choosing to have children nowadays.
