Aerobic exercise - the kind that raises your heart rate - appears to improve executive function, and the effect looks particularly pronounced in women after menopause. That is the finding from a Rutgers-led study published in the Journal of Alzheimer's Disease, headed by Sharon Sanz Simon, an assistant professor of psychiatry at Rutgers New Jersey Medical School and a core faculty member of the Herbert and Jacqueline Krieger Klein Alzheimer's Research Center within the Rutgers Brain Health Institute.
Executive function is the mental toolkit behind planning, shifting between tasks, holding attention and generally running your own life without assistance. Many women report that these particular skills feel harder to summon during and after the menopause transition, which makes the timing of the Rutgers result worth attention.
The stakes here are not abstract. Two-thirds of all Alzheimer's diagnoses occur in women, and the researchers frame the hormonal shift of midlife as a critical window for protecting brain health over the long run. It is also a period when many women scale back consistent physical activity, whether because of symptoms, competing stress or simply the absence of clear guidance on what kind of exercise supports thinking skills.
That gap in guidance is part of what makes this line of work useful: it points toward an accessible, non-pharmaceutical avenue at a specific moment in life when cognitive risk begins to diverge between men and women. How large and durable the benefit is, and for whom, will depend on further research.
