Associations of Cardiovascular Fat Quality with Memory Performance among Midlife Women

Women with excess cardiovascular fat may be at a higher risk for memory issues such as dementia. Women are disproportionately affected by cognitive decline, and a new study suggests that changes in cardiovascular fat after menopause may be a possible cause.

Cardiovascular fat deposition is higher in postmenopausal women compared to premenopausal women and is a risk factor for cardiovascular disease. Researchers now believe that it may affect cognitive function through neuropathological pathways by changing the secretion of inflammatory cytokines and adipokines. For the study, cardiovascular fat was characterized by its radiodensity.

For the study, researchers assessed the relationship of cardiovascular fat volume and radiodensity with future cognitive performance in women during midlife. Racial differences were also studied for any differences since black people generally have lower cardiovascular fat volume but are at a higher risk for heart disease and have a higher prevalence of Alzheimer’s disease compared with white people.

The study was based on SWAN (Study of Women’s Health Across the Nation) data and included nearly 500 women of which 30.6% were postmenopausal, and 35.9% were black.

It was found that a higher perivascular adipose tissue (PVAT) radiodensity was significantly associated with worse working memory. Researchers also identified a significant interaction between PVAT radiodensity and race, suggesting that higher baseline PVAT radiodensity after menopause was associated with lower future verbal episodic memory among blacks but not white women.

The study conclusion was independent of the volume of PVAT depot, waist circumference, and other known conditions that may interfere with results.

Quality, Not Quantity

“Our study suggests that the quality, rather than the quantity, of perivascular adipose tissue at midlife may serve as a novel biomarker of cognitive function status in women later in life. We need more research to understand the underlying mechanisms of the reported association,” says Dr. Samar R. El Khoudary from the University of Pittsburgh and senior author of the study.

Every avenue is being pursued for answers as to why women are more at risk for dementia. The incidence of the disease is higher in women than in men, and this cannot simply be attributed to the higher longevity of women versus men. This study helps to understand the relationship between cardiovascular fat in women and how it may be a contributing factor to a higher risk of cognitive decline.

Researchers believe studies such as this one can be valuable in helping healthcare providers identify who may be most at risk for cognitive decline so early intervention can be taken. When caught early, the progression of dementia and Alzheimer’s disease may be delayed.

Sarah began her interest in nutritional healing at an early age. After going through health problems and becoming frustrated with the conventional ways doctors wanted to treat her illness (which were not working), she took it upon herself to find alternative treatments. This led her to revolutionize her own diet to help her get healthier and tackle her health problems. She began treating her illness by living a more balanced lifestyle through healthy food choices, exercise and other alternative medicine such as meditation. This total positive lifestyle change led her to earn a diploma in Nutritional Therapy from Health Sciences Academy in London, England. Today, Sarah enjoys helping others by teaching healthy lifestyle changes through her personal consultations and with her regular contributions to the Doctors Health Press. Also, passionate about following her dreams in life, Sarah moved to France and lived in Paris for over 5 years where she earned a certification in beadwork and embroidery from Lesage (an atelier owned by Chanel). She then went on to be a familiar face sitting front row and reporting from Paris Fashion Week. Sarah continues to practice some of the cultural ways of life she learned while in Europe. They enjoy their food, and take the time to relax and enjoy many of life’s little moments. These are life lessons she is glad to have brought back home with her.
