Impaired spatial information processing in aged monkeys with preserved recognition memory

Spatial information processing was examined in a non-human primate model of cognitive aging, using procedures formally similar to tasks designed for rats. The test apparatus was a large open field containing eight reward locations. Monkeys rapidly learned to visit each location once per trial, and probe manipulations confirmed that young animals navigated according to the distribution of cues surrounding the maze. In contrast, aged monkeys solved the task using a response sequencing strategy, independent of extramaze spatial information. Object recognition memory was normal in the aged group. The results reveal substantial correspondence in the cognitive effects of aging across rat and primate models, and they establish appropriate procedures for testing the long-standing proposal that the role of the hippocampus in normal spatial learning is similarly conserved.     

Age and sex differences in cerebral hemodynamics: a transcranial Doppler study

BACKGROUND AND PURPOSE: Hemodynamic factors seem to play an important role in the pathogenesis of cerebral ischemic events. The aim of this study was to evaluate whether changes in cerebrovascular reactivity occur in women after menopause. METHODS: Using transcranial Doppler ultrasonography, we studied the changes of flow velocity after hypercapnia in the middle cerebral arteries of 45 healthy premenopausal women (mean age, 32.3 years; range, 20 to 47 years) and 40 postmenopausal women (mean age, 54.4 years; range, 48 to 64 years). The same measurements were recorded in two groups of healthy male subjects age matched with premenopausal (45 subjects) and postmenopausal women (40 subjects). Moreover, a subgroup of postmenopausal women aged 48 to 53 years (15 subjects) were compared with a group of 15 premenopausal women of the same age. We obtained hypercapnia with breath holding and evaluated cerebrovascular reactivity with the breath-holding index (BHI). RESULTS: BHI was significantly lower in postmenopausal women (0.89+/-0.3) than in premenopausal women (1.59+/-0.3; P<0.0001) and in young (1.34+/-0.5; P<0.001) and old men (1.20+/-0.4; P<0.04). In the latter group, BHI was significantly lower than in premenopausal women (P<.0001). BHI values were also significantly lower in postmenopausal than in premenopausal women of the same age (0.81+/-0.1 versus 1.34+/-0.1; P<0.0001). CONCLUSIONS: These findings suggest that the large reduction of cerebrovascular reactivity in postmenopausal women cannot be considered a simple factor related to aging but is probably influenced by hormonal changes. The alteration in cerebrovascular regulation could be involved in the increase of cerebrovascular disease in postmenopausal women.     

Thalamic NMDA transmission in a genetic model of absence epilepsy in rats

OBJECTIVES: Whether menopause per se influences fat distribution independently of the effect of aging remains controversial. The lack of consistency in the menopause related changes in body fat distribution may be the result of differences in the methods for measuring fat distribution or in the characteristics of the women studied. The aim of this cross sectional study in obese women was to compare total body composition and regional fat and lean distribution, in premenopausal, perimenopausal and postmenopausal women. METHODS: Body composition was assessed by dual energy X-ray absorptiometry (DEXA) in premenopausal (n = 26), perimenopausal (n = 24) and postmenopausal (n = 73) obese women with no intercurrent diseases. RESULTS: It was shown that postmenopausal obese (n = 73) women had a higher proportion of total fat mass in the trunk and a lower proportion of total fat and lean mass in the femoral and leg regions than premenopausal women after adjustment for age and total fat mass. In the same analysis, perimenopausal women had a lower proportion of total fat in the leg and femoral regions and of total lean in the femoral region than premenopausal women; they had a regional body composition similar to that of postmenopausal women. CONCLUSION: The present data indicate that in obese women, post menopause and perimenopause are associated with differences in fat and lean distribution, independently of age and total fat.     

Object discrimination learning in aged Japanese monkeys.

The authors investigated the behavioral aging effects of Japanese macaques in 3-object discrimination learning tasks: learning-set (LS) formation, go/no-go discrimination learning, and multiple discrimination reversals. Aged monkeys showed deteriorated performance in these tasks compared with younger controls. Hypothesis analysis of LS showed that aged monkeys had difficulty learning the lose-shift component of the hypothesis win-stay-lose-shift with respect to object. Deficits in go/no-go successive discrimination were clear in no-go trials only in the first 2 pairs of 5 tasks. Performance of aged monkeys was severely disturbed from a chance to criterion level in discrimination reversals. These results are attributed not only to increased tendency for perseveration but also to difficulty in associating the reward and the object in aged monkeys and may be related to the decline in the functions of the ventral frontal cortex.

Is there a means for cost reduction in intensive care fluid therapy without a loss of quality?

The objective of this study was to examine the value of NTx, a urinary cross-linked N-telopeptides of type I collagen, as a marker of bone resorption. We assessed changes in pre- and postmenopausal bone resorption by evaluating the correlation of NTx with L2-4 bone mineral density (BMD) in a total of 1100 Japanese women, aged 19-80 years [272 premenopausal (45.2 +/- 6.2 years) and 828 postmenopausal (59.5 +/- 6.2 years)]. Postmenopausal women were divided into three groups based on the range of BMD (normal, osteopenic, and osteoporotic). Within each group, subjects were further segregated according to years since menopause (YSM). NTx values were then evaluated for each group. Our results showed that BMD was significantly decreased (P < 0.05) and NTx was significantly increased (P < 0.01) after menopause in age-matched analysis. Consistent with a previous report, NTx was inversely correlated with BMD for the entire cohort of study subjects (r = -0.299), although NTx correlated better with premenopausal than postmenopausal BMD (r = -0.240 versus r = -0.086). This may have been due to the fact that elevated values of NTx were exhibited over the entire range of BMD present in the postmenopausal women, suggesting that NTx might respond faster to the estrogen withdrawal than BMD. In all postmenopausal women, regardless of the range of BMD, the increase in NTx reached a peak within 5 YSM. After 11 YSM, however, NTx remained elevated in the osteoporotic group but it decreased in the osteopenic group, and showed no significant change in the group of postmenopausal women with normal BMD. These findings suggest that bone resorption is dramatically increased within 5 years after menopause but remains increased only in osteoporotic women.     

Spatial orienting of attention in adult and aged rhesus monkeys.

Aging produces changes in a variety of neural systems that result in a distinct neuropsychological profile of cognitive deficits. To determine the extent of functional decline in cognition with aging, the authors assessed attentional ability in adult (10–15 yr old) and aged (28–33 yr old) rhesus monkeys (Macaca mulatta) in 3 experiments, using a paradigm adapted from M. I. Posner et al (1984), in which a peripheral cue indicates the probable location of a target. Orienting of attention was not disrupted in aged monkeys. Response times of aged monkeys were comparable with adult monkeys' both in the attention task and in a simple reaction time task. These results suggest that the neural systems that subserve spatial orienting of attention remain intact in aged nonhuman primates. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cognitive function in aged ovariectomized female rhesus monkeys.

To determine whether ovariectomy exacerbates age-related cognitive decline, the performance of 6 aged monkeys that had been ovariectomized early in life (OVX-Aged) was compared to that of 8 age-matched controls with intact ovaries (INT-Aged) and that of 5 young controls with intact ovaries (INT-Young) in tasks of visual recognition memory, object and spatial memory, and executive function. The OVX-Aged monkeys were marginally more impaired than the INT-Aged monkeys on the delayed nonmatching-to-sample with a 600-s delay. In contrast, they performed significantly better than the INT-Aged controls on the spatial condition of the delayed recognition span test. The hypothesis that prolonged estrogenic deprivation may exaggerate the age-related decline in visual recognition memory will require additional support. However, the findings suggest that long-term ovariectomy may protect against the development with aging of spatial memory deficits. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Regional distribution of 5alpha-reductase type 1 and type 2 mRNA along the human epididymis

BACKGROUND AND PURPOSE: In women, symptoms of coronary artery disease are delayed by 10 to 15 years in comparison with men, most likely because of the protective effect of ovarian hormones. This report compares the prevalence and degree of carotid atherosclerosis between 292 premenopausal women and 294 women at 5 to 8 years after menopause. METHODS: Scans were performed in the same laboratory over the same time period for both groups. Intima-media thickness (IMT) was averaged across the common, bulb, and internal carotids. The plaque index summarized degree of focal plaque based on the size and number of plaques throughout both carotid systems. RESULTS: Mean IMT was 0.69 mm for premenopausal women and 0.77 mm for postmenopausal women (P < 0.001). Prevalence of plaque was 25% among premenopausal women and 54% among postmenopausal women (P < 0.001). In both premenopausal and postmenopausal women, risk factors measured before menopause were associated with carotid atherosclerosis. Premenopausal risk factors independently associated with IMT were higher pulse pressure (P < 0.001), triglycerides (P = 0.002), body mass index (P < 0.001), and study group (a surrogate for both age and menopausal status; P < 0.001). Premenopausal risk factors independently associated with focal plaque were ever smoking (P = 0.002), higher pulse pressure (P = 0.028), higher LDL (P = 0.003), age at baseline (P = 0.050), and study group (P < 0.001). CONCLUSIONS: Subclinical carotid atherosclerosis can be observed in middle-aged women. Risk factors measured before menopause are clearly associated with subclinical disease measured both concurrently and at 5 to 8 years after menopause.     

Adenovirus-mediated in vivo gene transfer and expression in normal rat pancreas

Growth hormone (GH) secretion declines during normal aging along with reproductive activity in mammalian species. Various behavioral changes also occur in aged animals. In these experiments we have studied the effects of GH administration on behavioral and endocrine alterations exhibited by aged (18 months old) female rats of the Sprague-Dawley strain. Animals were selected showing at least 2 weeks of cornified vaginal smears (constant estrous) and treated with GH (0.1 mg/kg SC) daily for 8 weeks. Vaginal smears performed during the drug treatment revealed a recovery of estrous cycle in 60% of animals. GH treatment was also followed by an increased acquisition of shuttle-box active avoidance behavior and a facilitated retention of passive avoidance response. Compared to saline-injected controls, female rats treated with GH also exhibited a decrease of novelty-induced excessive grooming. The endocrine pattern of GH-treated aged female rats revealed a decrease in plasma prolactin levels and an increase in luteinizing hormone and 17 beta-estradiol levels as compared to those of control animals. These results support the concept that behavioral and endocrine alterations occurring in aging are not irreversible and that GH may interfere with these changes probably by means of its trophic action on different target organs.     

Ultrasound velocity of the tibia in normal German women and hip fracture patients

One of the latest developments in quantitative ultrasound (QUS) is the measurement of the speed of sound (SOS) of cortical bone of the midtibia. To determine the diagnostic validity of this method we measured 150 healthy women aged 22-94 years. Additionally, we report on first results of patients with hip fracture. Precision in vivo of the tibial QUS expressed as the percentage coefficient of variation (CV) was 0.39% for the first day and 0.45% after repositioning the second day (mean CV = 0.42%). No significant dependency of tibial SOS was found with weight, height, and body mass index in pre- and postmenopausal women. There was a significant decline of SOS with age in postmenopausal women (SOS = 4225 - 5.3 age, r = -0.46, P < 0. 001), whereas premenopausal women showed no decline (SOS = 3906 + 1. 3 age, r = 0.13, ns) Mean SOS values of premenopausal women were significantly higher than those of postmenopausal women (3960 +/- 78.7 m/second and 3898 +/- 120 m/second, respectively, P < 0.001). Postmenopausal women on estrogen substitution had significantly higher mean tibial SOS values than age-comparable postmenopausal women without estrogen substitution (3980 +/- 99 m/second and 3869 +/- 100 m/second, respectively, P < 0.001). Significant difference between age-matched healthy women, n = 11, and hip fracture patients, n = 13, expressed as z-score of -1.4 SD was found. In conclusion, tibial QUS declines with age and detects higher values in premenopausal women and postmenopausal women on estrogen substitution and lower values in hip fracture patients. Further prospective studies are needed to clarify its role in fracture risk assessment.     

Posture, age, menopause, and osteopenia do not influence the circadian variation in the urinary excretion of pyridinium crosslinks

This study was performed to investigate whether the circadian variation in urinary pyridinium crosslinks is related to physical activity, age, the menopause, and asymptomatic osteopenia. We measured urinary pyridinoline/creatinine (Pyr/Cr) and deoxypyridinoline/creatinine (D-Pyr/Cr) in 9 healthy premenopausal women in two 27 h studies, before and at the end of 5 days of total bed rest. Both Pyr/Cr and D-Pyr/Cr showed highly significant circadian variations, with the peak at night and the nadir during the day (p < 0.001). The 5 days of complete bed rest produced no changes in the circadian pattern, but a general increase of 28% was observed in pyridinium crosslinks. A group of 12 healthy, early postmenopausal women (aged 55 +/- 2 years), 12 healthy, elderly postmenopausal women (aged 73 +/- 1 years), and 12 elderly osteopenic but otherwise healthy women (aged 73 +/- 1 years) were also studied for 27 h. All three groups showed highly significant (p < or = 0.001) circadian variations in the urinary excretion of pyridinium crosslinks. As expected, both Pyr/Cr (p < 0.05) and D-Pyr/Cr (p < 0.001) increased at the time of menopause, but the circadian variations in Pyr/Cr and D-Pyr/Cr were similar in all groups studied. We conclude that the circadian variation in the urinary excretion of pyridinium crosslinks is independent of physical factors. Furthermore, the circadian variation in pyridinium crosslinks was not related to age, menopausal status, or asymptomatic osteopenia.     

Hormone replacement and menopausal symptoms following hysterectomy

Hormone replacement therapy (HRT) is recommended for most women who experience surgical menopause following hysterectomy/oophorectomy for noncancerous conditions; it is also commonly prescribed for postmenopausal women. Beginning in 1992, 1,299 women undergoing hysterectomy in 28 hospitals throughout Maryland were interviewed prior to hysterectomy and were subsequently followed over a 2-year period. Interviews included questions about HRT use and symptoms associated with menopause. The majority of the women (66 percent) were white, 55 percent had a high school education or better, 49 percent were obese (body mass index > or =27.3), and 11 percent were postmenopausal. Over 40 percent of premenopausal women underwent bilateral oophorectomy. At 3 months posthysterectomy, 89 percent of these women were on HRT; this figure dropped to 85 percent at 24 months. Among postmenopausal women, 50 percent were on HRT both at 3 months and at 24 months posthysterectomy. Among premenopausal women who had unilateral oophorectomy, 21 percent were on HRT at 3 months, increasing to 35 percent at 24 months. Among premenopausal women who had no ovaries removed, 5 percent were on HRT at 3 months, increasing to 13 percent at 24 months. There were few within-group differences between HRT users and nonusers, except that among postmenopausal women, HRT users were younger and more likely to be white and had higher income and educational levels. Women who were postmenopausal or who underwent bilateral oophorectomy were less likely to have hot flashes if they were on HRT, but women with 0-1 ovary removed who were on HRT were more likely to have hot flashes than those not on HRT. Black women were significantly more likely to experience hot flashes than were white women, independent of HRT status and weight. Obese women were on HRT at approximately the same rates as nonobese women but were significantly more likely to have hot flashes, even when analyses controlled for HRT and race.     

Cell surface binding and cellular internalization properties of suramin, a novel antineoplastic agent

BACKGROUND: A number of factors contribute to increased risk of coronary heart disease (CHD) among postmenopausal women, including atherogenic changes in serum cholesterol profiles, weight gain, and decreases in physical activity during the menopause. To date, no study has attempted to prevent elevations in primary CHD risk factors as women experience menopause. METHODS: A sample of 535 healthy premenopausal women, ages 44-50, were recruited for an ongoing 5-year randomized prevention trial testing whether increases in low-density lipoprotein cholesterol (LDL-C) and body weight can be prevented during the menopause with a dietary and behavioral intervention. The aim was to reduce total dietary and saturated fat and cholesterol, prevent weight gain, and increase physical activity levels. Changes in CHD risk factors after the first 6 months of treatment were analyzed comparing 253 intervention and 267 assessment-only control participants. RESULTS: The intervention group showed significant reductions in total cholesterol (-0.34 mmol/liter), LDL-C (-0.28 mmol/liter), triglycerides (-0.04 mmol/liter), weight (-4.8 kg), waist-hip ratio (-0.008), systolic blood pressure (-3.5 mm Hg), diastolic blood pressure (-2.2 mm Hg), serum glucose levels (-0.06 mmol/liter), and HDL-C (-0.06 mmol/liter) and significant increases in physical activity (+383 kcal). No significant changes were observed in the control group. CONCLUSION: Six-month results suggested that participants were receptive to the preventive approach to CHD risk reduction and were successful in making initial positive lifestyle changes. Follow-up data will evaluate long-term adherence to the intervention and the interaction between adherence and physiological changes during menopause.     

Severe manifestations in carrier females in X linked retinitis pigmentosa

The aim of this study was to assess the effect of menopause on circadian profile of blood pressure (BP) and heart rate (HR) in the normotensive pre- and postmenopausal women. Systolic BP (SBP), diagnostic BP (DBP) and HR were monitored every 30 min for 48 hrs using noninvasive ambulatory BP monitoring in 24 premenopausal and 40 postmenopausal women. Mean 48-hours, daytime (awake), and nighttime (sleeping) SBP, DBP and HR values were analyzed by reviewing the patients' diaries, and the nocturnal reduction rate (NRR) of SBP, DBP and HR were calculated according to the following formula. NRR (%9 = [(daytime mean-nighttime mean)/daytime mean] x 100. The study subjects were then divided into two groups according to the presence (dipper) or absence (nondipper) of a significant reduction in nocturnal BP (> 10%). Mean SBP, DBP and HR measured over 48 hours were similar between the premenopausal and the postmenopausal group. The NRR of DBP and HR in the postmenopausal group were significantly smaller than those in the premenopausal group (17.1 +/- 6.0% vs. 13.5 +/- 7.0%, 241.1 +/- 6.0% vs. 19.8 +/- 9.0%: p < 0.05). There tended to be higher prevalence of nondipper in the postmenopausal (37%) than in the premenopausal group (29%).     

Mood and symptom reporting among middle-aged women: The relationship between menopausal status, hormone replacement therapy, and exercise participation.

Vasomotor, somatic, and psychological symptoms associated with menopause are often treated with hormone replacement therapy (HRT), but the role of nonpharmacological interventions has received little attention. Two studies used the Profile of Mood States (POMS) and Women's Health Questionnaire (WHQ) to examine the effects of exercise among 4 groups of Australian women: premenopausal, perimenopausal, postmenopausal without HRT, and postmenopausal with HRT. Study 1, a comparison of exercisers and nonexercisers, showed that exercisers' moods were significantly more positive than sedentary women's moods, regardless of menopausal state. Exercising women also scored lower on somatic symptoms and memory-concentration difficulties. Study 2 examined the acute effects of aerobic exercise (premenopausal, postmenopausal without HRT, and postmenopausal with HRT) and found significant enhancements in mood and reductions in reported somatic and vasomotor symptoms immediately following an aerobic class. Exercise may assist in the alleviation of some menopausal symptoms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Long-term clinical follow-up after directional coronary atherectomy

We designed a prospective observational trial to study the relationship of thyroid function to cholesterol and weight changes at menopause. Subjects were participants in the ongoing Healthy Women Study, a prospective study of cardiovascular risk factor change through menopause. Healthy premenopausal women were recruited from a random sample of licensed drivers in selected ZIP codes of Allegheny County, Pennsylvania. Participants had to be 42-50 years of age, have menstruated within the last 3 months, not have had surgical menopause, have diastolic blood pressure < 100 mm Hg, and not be taking medications (including insulin, estrogen, lipid-lowering drugs, or thyroid or antihypertensive medications) at the baseline examination. The substudy included three groups of women who were premenopausal at baseline and were categorized according to change noted at follow-up regarding menopausal status and use of hormone replacement therapy (HRT). The groups comprised 95 women who remained premenopausal, 96 postmenopausal women not on HRT, and 61 postmenopausal women using HRT. The main outcome measures were baseline and follow-up measurements for serum levels of thyroid-stimulating hormone (TSH), thyroid peroxidase, and thyroglobulin, as well as serum cholesterol, total high-density lipoprotein (HDL) cholesterol, triglycerides, and calculated low-density lipoprotein (LDL) cholesterol, height, and weight. Covariates included cigarette smoking and alcohol intake. The prevalence of thyroid antibodies in this healthy population was high at both time points (range 27%-31%) and did not differ by menopausal status. The presence of thyroid antibodies was associated with increased TSH concentration. Women with antibodies at both time points had lower levels of total and LDL cholesterol compared with those with no antibodies, significant only for those women who remained premenopausal during the follow-up period. Thyroid function during menopause in this healthy population is unlikely to account for the observed changes in levels of serum lipoprotein and body weight. The presence of thyroid antibodies may be associated with lower total and LDL cholesterol, possibly through an underlying inflammatory disorder.     

Hormones and sexuality in postmenopausal women: a psychophysiological study

Sexual function, including vaginal atrophy, and hormonal status, were studied in 42 naturally postmenopausal women. Vaginal pulse amplitude and subjective sexual responses during self-induced erotic fantasy and during erotic films were compared with responses of a small number of premenopausal women. As predicted, vaginal atrophy was related to estrogens but not to complaints of vaginal dryness and dyspareunia. No significant relationship was found between hormones and sexual function. Unexpectedly, most of the few correlations that did reach significance involved prolactin. The fact that prolactin was negatively associated with sexual desire, sexual arousal and vaginal lubrication during sexual activity, suggests that psychosocial factors are more important than hormone levels in postmenopausal sexual function. Comparisons with a number of premenopausal women revealed that although postmenopausal women displayed lower vaginal pulse amplitude responses prior to erotic stimulation than the premenopausal women, this difference disappeared during subsequent erotic stimulation. We argued that this finding can be interpreted as being supportive of the notion that complaints of vaginal dryness and dyspareunia should not be attributed to vaginal atrophy associated with menopause. Rather, vaginal dryness and dyspareunia seem to reflect sexual arousal problems.     

Effects of AF102B and tacrine on delayed match-to-sample in monkeys

1. Object working memory, a function which declines in aging and dementia, was tested in young and aged pretrained monkeys using a delayed match-to-sample task. 2. During drug treatment, monkeys were given the m 1 muscarinic agonist AF102B (0.1-2.1 mg/kg i.m.), the cholinesterase inhibitor tacrine (0.5-2.0 mg/kg p.o.), or vehicle controls in a repeated measures design to assess putative cognitive enhancement. 3. Both agents improved task performance in both young and aged monkeys, AF102B yielding equivalent or greater, and less variable, improvement than tacrine. 4. AF102B may represent a low-toxicity alternative to tacrine for the treatment of age-related memory disorders.     

Biobehavioral aspects of menopause: lessons from the Healthy Women Study

The Healthy Women Study is an ongoing natural history study of the menopause in a sample of relatively healthy women. We report data from this paper on the behavioral and biological changes that occur during the transition from pre- to postmenopausal status and argue for the importance of behavioral change interventions to prevent or attenuate some of the adverse changes due to the menopause.     

Influence of the perimenopause on cardiovascular risk factors and symptoms of middle-aged healthy women

OBJECTIVE: To determine the changes in cardiovascular risk factors and psychological and physical symptoms that occur during the perimenopause. DESIGN: Cohort study of 541 healthy middle-aged premenopausal women followed up through the menopause. SETTING: General community. PARTICIPANTS: After a baseline evaluation taken at study entry, 152 women ceased menstruating for 3 months (not due to surgery) and were not using hormone replacement therapy, and were reevaluated in a similar protocol (perimenopausal examination); 105 of the 152 were evaluated a third time when they had ceased menstruating for 12 months and were not using hormone replacement therapy (postmenopausal examination). One hundred nine premenopausal women who were repeatedly tested constituted a comparison group. MAIN OUTCOME MEASURES: Levels of lipids and lipoproteins, triglycerides, fasting glucose and insulin, blood pressure, weight, height, and standardized measures of psychological symptoms. RESULTS: Women who became perimenopausal showed increased levels of cardiovascular risk factors, which were similar in magnitude to those experienced by the comparison group of premenopausal women. Perimenopausal women reported a greater number of symptoms, especially hot flashes, cold sweats, joint pain, aches in the skull and/or neck, and being forgetful; reports of hot flashes at the perimenopausal examination were associated with low concentrations of serum estrogens. Menopausal status was not associated with depressive symptoms. Perimenopausal women who became postmenopausal showed a decline in the level of high-density lipoprotein-2-cholesterol (means, 0.53 to 0.43 mmol/L [20.6 to 16.7 mg/dL]) and a gradual increase in the level of low-density lipoprotein cholesterol (means, 3.14 to 3.33 mmol/L [121.3 to 128.8 mg/dL]), whereas symptom reporting declined. CONCLUSIONS: During mid-life, women experience adverse changes in cardiovascular risk factors and a temporary increase in total number of reported symptoms, with no change in depression. Preventive efforts to reduce the menopause-induced increase in cardiovascular risk factors should begin early in the menopausal transition.
