Polycystic ovary syndrome (PCOS) has been found to be associated with lower scores on cognitive function tests in middle-aged women, according to a cohort study published in Neurology. The study followed women with PCOS for 30 years and found that they performed significantly lower on a composite of cognitive function tests compared to women without PCOS. This difference was mainly driven by lower scores in tests measuring executive functioning, memory, and verbal fluency.
The findings of this study have important implications for public health, considering that up to 10% of women may have PCOS. The lower cognitive test scores observed in women with PCOS suggest that there may be a need for greater attention to mental health in this population. Addressing the mental health needs of women with PCOS could potentially improve cognitive health and overall well-being.
Women with PCOS were found to have higher rates of depressive symptoms and diabetes compared to those without PCOS. These comorbidities may contribute to the lower cognitive test scores observed in this population. It is important to consider the mental health needs of women with PCOS and provide appropriate support and interventions.
A subset of women with PCOS underwent MRI, and the results showed lower white matter fractional anisotropy, indicating decreased white matter integrity, in women with PCOS. The affected regions included the frontal, parietal, temporal, occipital, limbic, and corpus callosum white matter. These findings suggest potential early brain aging in women with PCOS, although further research is needed to confirm these results.
Reproductive and metabolic factors have important connections to brain health. While they are often considered separate entities, this study highlights the profound interplay between these factors. Lifestyle changes and interventions targeting reproductive and metabolic health may have the potential to improve cognitive outcomes in women with PCOS.
The study utilized data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, which included a diverse population of Black and white individuals. The cohort consisted of women aged 18-30 years at baseline, and follow-up cognitive testing was conducted approximately 30 years later. Of the women who completed the cognitive testing, 7.1% met the criteria for PCOS.
It is important to acknowledge the limitations of this study. The sample sizes were relatively small, which may limit the generalizability of the findings. Unmeasured confounders and factors not accounted for in the analysis may have influenced the results. Additionally, the study was unable to determine the clinical significance of the observed cognitive deficits. Further research with larger sample sizes and more detailed assessments is needed to confirm and expand upon these findings.
Polycystic ovary syndrome was found to be associated with lower cognitive test scores in middle-aged women. The cognitive deficits observed in women with PCOS may be influenced by depressive symptoms, diabetes, and altered white matter integrity. Addressing the mental health needs of women with PCOS and promoting lifestyle interventions targeting reproductive and metabolic health may help improve cognitive outcomes in this population. Further research is necessary to fully understand the underlying mechanisms and develop effective interventions for women with PCOS.
