While you may experience the misery of hot flashes and mood swings as you enter menopause, one thing you can't blame on the "change" is memory loss.

In the latest study that exonerates menopause as a cause of impairing the ability to recall, Taiwanese researchers compared the memory of hundreds of women before they had any menopausal symptoms to their memory as they entered menopause.

They found the women who were going through the menopausal process scored as well or nearly as well on five different cognitive function tests. Results of the study are to be presented Oct. 4 at the American Neurological Association annual meeting in Toronto.

"When women go into perimenopause, they don't need to worry about cognitive decline," said Dr. Jong-Ling Fuh, an attending physician at Taipei Veterans General Hospital and an associate professor of Yang-Ming University School of Medicine.

The researchers said the myth of memory loss during menopause is a perception some women have because as they went through menopause, they felt their memory wasn't as sharp as it had been before. Studies suggesting that hormone replacement therapy might protect against dementia strengthened that belief. However, a large study later found that in older women, hormone replacement therapy not only didn't help protect women from dementia, but could actually increase the risk.

To try to answer the question of whether menopause did have any effect on memory, Fuh and her colleagues studied nearly 700 premenopausal women living on a group of rural islands between Taiwan and China. The Taiwanese government restricted access to these islands until the 1990s, so the authors report that the study's population was nearly homogeneous, which would help rule out other potentially causative factors of memory loss.

The women were between the ages of 40 and 54. None of them had had a hysterectomy, and none took hormone replacement therapy during the study.

All took five cognitive tests designed to assess their memory and cognitive skills at the start of the study, and then again 18 months later.

During the study period, 23 percent of the women began to have symptoms of menopause.

The researchers then compared the memory of the women who had entered menopause to those who had not, and found very little difference. In four of the five tests, there were no statistically significant differences in the two groups of women.

Only on one test was the difference statistically significant, and that difference, said Fuh, was very slight. This test was designed to assess verbal memory and involved showing the women 70 nonsensical figures. Some of the figures were repeated during the test, while most were not. The women were asked whether they had seen the figure earlier.

"For women, menopause does not mean you'll develop memory loss," said Dr. Raina Ernstoff, an attending neurologist at William Beaumont Hospital in Royal Oak, Mich. As you're going through perimenopause and experiencing symptoms like hot flashes, she said, you may feel lousy and have trouble sleeping, which might temporarily affect your cognitive skills.

"I don't think declining estrogen levels are what causes memory loss," said Dr. Steven Goldstein, an obstetrician/gynecologist at New York University Medical Center in New York City. "It's not like your memory is bopping along, doing fine and then takes this big dive during menopause, like bone density can."

Both Ernstoff and Goldstein said they weren't aware of many women who believed that menopause might cause significant memory loss. They also both felt that results from this group of women who were so homogeneous might not apply to different groups of women, such as those living in more industrialized society. And they both said that other factors that weren't studied could play a role in memory loss, such as hypertension, which can contribute to vascular dementia.

Ernstoff also pointed out that the education backgrounds can play a large role in memory loss. Fuh acknowledged the researchers did attempt to control the data for educational differences

MEMORY LOSS AT MENOPAUSE

Many women going through menopause experience the same kind of forgetfulness that new mothers do and despair, assuming mental decline has begun. The good news: It hasn't. In one issue of the American Journal Neurology reported that a study of more than 800 menopausal women over two years showed that if they're forgetful sometimes, it's more likely because they are busy, distracted and stressed-out with middle-age pressures: teenager children, elderly parents and career demands.

The researchers found no proof those hormonal changes in menopause cause forgetfulness. It may be that the brain does not need the hormones as much as we think

Along with the hot flashes, sleepless nights and mood swings, many women also report another symptom that comes along with menopause: forgetfulness.

"The researchers found no link between "forgetful" women going through menopause and Alzheimer's, but they did find something else: the forgetfulness doesn't stem from an impaired memory, it stems from stressed women with busy lives who have harder time learning, or "encoding," new information.

Not a Memory Problem After All

"This is not what most people think of traditionally when they think of memory loss," "It feels like a memory problem, but the cause is different. It feels like you can't remember, but that's because you never really learned the information in the first place."

The researchers tested several cognitive skills of 24 women who complained of memory problems. They found, as previous studies have, no evidence that the women, who were approaching menopause, had any more memory problems than the rest of the population.

What they did find, however, was that the women had harder time learning new information, which could be mistakenly perceived as a memory problem. None of the women actually had an impaired ability to learn new information, the researchers pointed out.

Hectic Lives, Stress and Hormones May All Play a Part

The team compared the problem to a doctor's visit in which a patient is told something serious is wrong, then given a lot of detailed information. Chances are that when the patient gets home he or she won't remember a lot of it, simply because they were so worried and distracted at the time of the conversation. The information wasn't forgotten, it was never really heard in the first place.

Such is the case with many middle-aged women who juggle careers, kids, home responsibilities and aging parents on a daily basis.

"When people spread their attention thin, it's difficult to encode new information. When they're worried or anxious about being late for work, or the problems of an aging parent -- that sort of stress can rob your attention resources and impact your ability to encode information properly," said Mapstone.

Ironically, not worrying about the forgetfulness could actually help to alleviate the problem,

"What characterizes these women is that they're being pulled in a lot of different directions ... Then they're going through this dramatic hormonal change ... There really is something going on. And perhaps knowing that their perceived problems with memory do not suggest early dementia might alleviate their concerns and actually improve their functioning -- it's one less thing to worry about,".

Easing Menopausal Symptoms Naturally

If you're a woman in your mid-40s or early 50s and menopause-related symptoms have you feeling tired, sweaty, achy, bloated and moody, there are some simple tricks that can help.

1. Ease Stress

As the study above found, simply putting too much on your plate can lead to increased feelings of "forgetfulness" and will also certainly make you more tired and moody. Make stress-relief a priority in your life by:

• Setting aside time to do something you like everyday.
• Learning to say "no" if you feel overwhelmed.
• Incorporating relaxation, such as taking a warm bath or doing yoga, into your daily routine.
• Surrounding you with positive-minded friends and family.

2. Try a NATURAL progesterone cream

Producing the proper levels of progesterone in your body is key to keeping you hormonally balanced, and therefore more energized. But only truly natural versions (not the synthetic Diosgenin) are recommended. Only USP progesterone powder is bio-identical to the naturally occurring progesterone in your body.

3. Exercise

"Exercise compensates nicely for declining levels of estrogen," said Wolfgang Kemmler, PhD, who led a study on the topic. The German study of 78 early postmenopausal women found that women who exercised for one hour (with both aerobic and strength training) four days a week experienced fewer:

• Migraines
• Mood swings
• Bouts of insomnia

... than women who did not exercise. They also had the added benefits of:

• Maintaining bone mass
• Losing 2 percent body fat and one inch from their waists
• Reducing cholesterol by 5 percent

On the other hand, women who did not exercise lost 8 percent of their bone mass and had increases in body fat, waist measurements and cholesterol.
