Acute stress in pri- and postmenopausal women is associated with more depressive symptoms, while chronic stress showed greater association with memory and concentration problems, according to research presented at the annual meeting of the Menopause Society (formerly the North American Menopause Society).
“This work suggests that markers of hypothalami-pituitary-axis activation that capture total cortisol secretion over multiple months, [such as] hair cortisol, strongly correlate with cognitive performance on attention and working memory tasks, whereas measures of more acute cortisol, [such as] salivary cortisol, may be more strongly associated with depression symptom severity and verbal learning,” Christina Metcalf, PhD, an assistant professor of psychiatry in the Colorado Center for Women’s Behavioral Health and Wellness at the University of Colorado at Denver, Aurora, told attendees. “Given the associations with chronic stress, there’s a lot of potential here to increase our knowledge about how women are doing and managing stress and life stressors during this life transition,” she said.
The study involved collecting hair and saliva samples from 43 healthy women in late perimenopause or early postmenopause with an average age of 51. The participants were predominantly white and college educated. The hair sample was taken within 2 cm of the scalp, and the saliva samples were collected the day after the hair sample collection, at the start and end of a 30-minute rest period that took place between 2:00 and 3:00 p.m. local time.
All the participants had an intact uterus and at least one ovary. None of the participants were current smokers or had recent alcohol or drug dependence, and none had used hormones within the previous 6 months. The study also excluded women who were pregnant or breastfeeding, who had bleached hair or no hair, who were taking steroids, beta blockers or opioid medication, and who had recently taken NSAIDS.
Measuring hair cortisol more feasible
The study was conducted remotely, with participants using video conferencing to communicate with the study personnel and then completing study procedures at home, including 2 days of cognitive testing with the California Verbal Learning Test – Third Edition and the n-back and continuous performance tasks. The participants also completed the Center for Epidemiologic Studies Depression Scale (CES-D).
Participants with higher levels of hair cortisol and salivary cortisol also had more severe depression symptoms (P < .001). Hair cortisol was also significantly associated with attention and working memory: Women with higher levels had fewer correct answers on the 0-back and 1-back trials (P < .01) and made more mistakes on the 2-back trial (P < .001). They also scored with less specificity on the continuous performance tasks (P = .022).
Although no association existed between hair cortisol levels and verbal learning or verbal memory (P > .05), participants with higher hair cortisol did score worse on the immediate recall trials (P = .034). Salivary cortisol levels, on the other hand, showed no association with memory recall trials, attention or working memory (P > .05).
Measuring cortisol from hair samples is more feasible than using saliva samples and may offer valuable insights regarding hypothalamic-pituitary-axis activity “to consider alongside the cognitive and mental health of late peri-/early postmenopausal women,” Dr. Metcalf told attendees. The next step is to find out whether the hypothalamic-pituitary-axis axis is a modifiable biomarker that can be used to improve executive function.
The study was limited by its small population, its cross-sectional design, and the lack of covariates in the current analyses.
Monitor symptoms in midlife
Hadine Joffe, MD, MSc, a professor of psychiatry and executive director of the Mary Horrigan Connors Center for Women’s Health and Gender Biology at Brigham and Women’s Hospital and Harvard Medical School, both in Boston, said the study findings were not surprising given how common the complaints of stress and depressive symptoms are.
“Mood changes are linked with acute, immediate cortisol levels at the same point in time, and cognitive symptoms were linked to more chronically elevated cortisol levels,” Dr. Joffe said in an interview. “Women and their providers should monitor for these challenging brain symptoms in midlife as they affect performance and quality of life and are linked with changes in the HPA axis as stress biomarkers.”
Because the study is small and has a cross-sectional design, it’s not possible to determine the direction of the associations or to make any inferences about causation, Dr. Joffe said.
“We cannot make the conclusion that stress is adversely affecting mood and cognitive performance given the design limitations. It is possible that mood and cognitive issues contributed to these stress markers,” Dr. Joffe said.”However, it is known that the experience of stress is linked with vulnerability to mood and cognitive symptoms, and also that mood and cognitive symptoms induce significant stress.”
The research was funded by the Menopause Society, Colorado University, the Ludeman Family Center for Women’s Health Research, the National Institute of Mental Health, and the National Institute of Aging. Dr. Metcalf had no disclosures. Dr. Joffe has received grant support from Merck, Pfizer and Sage, and has been a consultant or advisor for Bayer, Merck and Hello Therapeutics.
