Near Menopause, Women's Memory May Seem Worse Than It Really Is

Feb. 3, 2006 -- As menopause nears, some women blame their shifting hormones for memory problems. But it's not quite that simple, a new study shows.
The study included 24 women aged 40-60 who were approaching menopause. They took tests of memory, mood, mental skills, and estrogen blood levels.
The women's memories were largely fine, regardless of estrogen level or the women's sense that their memory used to be sharper. However, women showing signs of depression or anxiety scored lower on tests of mental skills, and blood tests showed lower estrogen levels in anxious women.
Miriam Webster, PhD, and Mark Mapstone, PhD, from the University of Rochester's Memory Disorders Clinic conducted the study. Their findings were presented in Boston at the International Neuropsychological Society's annual meeting.
Menopause is a natural process in which women's sex hormones diminish, signaling the end of women's childbearing years.
Menopause is not a disease. However, many women report physical, emotional, and memory-related symptoms related to menopause.
The women studied by Weber and Mapstone were from Rochester, N.Y. They hadn't finished menopause, but they reported at least one change in their menstrual cycle in the past year. Based on those changes and the women's age, participants were "perimenopausal," or approaching menopause, the researchers note.
None of the women was taking hormone replacement therapy or had major neurological or psychological problems.
No Memory Problems
Most women in the study stated that their memories had declined. But in a memory test, only one woman showed memory impairment. In short, most women gave their memories too little credit.
Fifteen of the women had symptoms of mild-to-moderate anxiety or depression, though none was found to have a mood disorder.
"While most women reported memory loss and mood disruption, there was little evidence of memory impairment or formal mood disorder on objective testing," the researchers write.
"Overall, the group did not score in the impaired range on any cognitive test," they note. "However, several women performed lower than expected on cognitive measures." Those cognitive tests included attention, organization, and visual skills.
