Contrary to popular belief, women do not suddenly start to lose their memory when menopause begins, according to a study presented October 4, 2004, at the 129th annual meeting of the American Neurological Association in Toronto.
Researchers in Taiwan studied women around the menopausal shift and found scant evidence for memory deficits in women during the early part of menopause.
A number of factors have contributed to the common belief that memory loss is an inevitable part of menopause, not the least of which is the perception by women themselves that they become more forgetful during or after menopause. In addition, some, but not all, studies of the effects of hormonal replacement therapy (HRT) have indicated that women who use HRT have less cognitive decline following menopause and lower rates of Alzheimer's disease. This research has been supported by a large body of experimental evidence that estrogen helps to keep brain cells healthy.
In this atmosphere, memory preservation has been viewed as a possible advantage of HRT, and many women use herbal supplements containing plant estrogens, touted as memory protective.
However, a well-publicized study released last year by researchers at Rush University in Chicago contradicted the idea of memory loss during menopause. In the present study, Jong-Ling Fuh, MD, of Taipei Veterans General Hospital in Taiwan and colleagues reveal findings that support this conclusion.
Fuh and colleagues took advantage of an ongoing study of women who live in a rural archipelago of islands called Kinmen (or Quemoy), located between Taiwan and the Chinese mainland. Until the mid 1990s, access to the island was restricted by the Taiwanese government, which maintained many military bases in Kinmen. Thus, the population remains relatively homogenous, making it attractive for epidemiological studies.
