New study suggests menopause not linked to memory decline

23.09.2003


Transitioning through menopause is not accompanied by a decline in working memory and perceptual speed, according to a study appearing in the Sept. 23 issue of Neurology Journal. In the study, led by researchers at the Department of Preventive Medicine, Rush-Presbyterian-St. Luke’s Medical Center in Chicago, 803 randomly selected Chicago-area African American and white women aged 40 to 55 were tested annually for loss of brain function over the course of six years. The study, begun in 1996, is the first longitudinal study to track cognitive performance during menopause.



Participant scores were compared annually for women in premenopausal, during menopause, and postmenopausal groups. According to a "Patient Page" on menopause and brain function that appears in the Neurology Journal issue, "If menopause harms brain function, the test scores should have gone down the most for the postmenopause group, less for the group in menopause and not at all for the group not yet in menopause. The study did not find that pattern of decline. In fact, most groups improved their scores over time. In those groups that did go down, the size of the decline was so small that it could not be linked to menopause."

"The study is important because it shows that there is little or no risk for immediate memory loss during perimenopause," said Sam Gandy, M.D., Ph.D., vice chair of the Alzheimer’s Association’s Medical and Scientific Advisory Council, and director, Farber Institute for the Neurosciences of Thomas Jefferson University. "The issue for Alzheimer’s disease is that it begins a decade or more before clinical cognitive or psychological changes are apparent. There remains an issue of whether perimenopausal hormone replacement therapy (HRT) would be useful in preventing AD later on, and this study does not answer that question."


The study concludes that further analyses of other measures from the Study of Women Across the Nation (SWAN) may provide additional insight into factors associated with cognitive change during menopause. It may be, as some researchers have found, that cognitive functioning is related more to psychosocial predictors such as depression, stress, marital status, work, activity level, smoking status, overall health and obesity.

SWAN is an NIA-sponsored study of the natural history of the menopausal transition in a cohort of about 3,300 women from five ethnic groups who are assessed annually.


The Alzheimer’s Association is the world leader in Alzheimer research and support. To date, the Association has funded more than $150 million in Alzheimer research. Through a national network of advocates and chapters, the association advances research, improves services and care, creates awareness of Alzheimer’s disease and mobilizes support.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
