A new, large-scale study suggests that having sons may accelerate cognitive aging in parents more than having daughters. Published in the Journal of Psychiatric Research, the research analyzed data from more than 13,000 mothers and fathers and found that individuals with at least one son showed a significantly faster decline in cognitive functions such as memory, attention, and reasoning. Importantly, the study took into account potentially confounding factors—such as level of education, household income, and overall physical health—to isolate the effect of child gender.

The researchers, whose affiliates included Columbia University and Charles University, proposed that raising boys might create additional mental or emotional stress compared to raising girls. According to a summary on YourTango, sons tend to be more physically active and may demand more hands-on care and supervision in childhood, which over time may contribute to chronic stress. This increased demand could have long-term cognitive costs for parents, as chronic stress is known to impair memory, executive function, and other mental processes.

Moreover, the study observed a dose-response effect: the magnitude of cognitive decline appeared to scale with the number of sons a parent had. Parents with more boys showed more pronounced cognitive decline, suggesting that the effect is not simply binary (son vs. daughter), but potentially cumulative. This finding raises intriguing questions about how parental workload, resources, and mental resilience interact over decades.

Still, it’s important to clarify what “faster cognitive decline” really means. The study does not suggest that having sons causes dramatic, early-onset dementia or a sudden collapse in mental ability. Rather, the decline is gradual and measured, relative to parents with daughters. In many cases, the changes may be subtle and detectable only in large population studies—not dramatic enough for a parent to directly perceive in daily life.

Experts caution that this study shows correlation rather than direct causation. While raising sons may be associated with increased parental stress or cognitive burden, many other factors—such as social support, parenting style, genetics, and lifestyle—are almost certainly at play. Some scientists also point out that long-term mental health support, regular social engagement, and self-care in midlife could help mitigate any potential mental aging associated with parenting.

These findings also touch on broader societal issues, such as gender expectations and the unequal burden parents may face based on the gender roles of their children. If confirmed by further research, the study underscores the importance of supporting parents—especially those with multiple sons—with resources for stress reduction, parenting education, and mental well-being.

In summary, this new research provides compelling evidence that parenting boys—and particularly multiple boys—may pose unique cognitive challenges over time. While not a definitive conclusion about cause and effect, the work highlights how family dynamics, child behavior, and parental stress can intersect with long-term brain health. Awareness of these potential impacts could encourage parents, policymakers, and health professionals to prioritize interventions that reduce stress and support healthy cognitive aging.
