Additional menopausal characteristics such as hot flashes and depression suggest that treatment for these conditions can help improve quality of life among this cohort during this stage of change.
The new study has been published online in Menopause, the journal of The North American Menopause Society (NAMS).
Investigators discovered other life stages — whether it was premenopause, perimenopause, or postmenopause — did not seem to be related to these women’s thinking skills.
The conclusions come from a new analysis of data on 708 HIV-infected and 278 HIV-uninfected midlife women from the Women’s Interagency HIV Study (WHIS), a national study of women with HIV at six sites across the country (Chicago, Bronx, Brooklyn, San Francisco, Los Angeles, and Washington, DC).
Today, nearly 52 percent of persons with HIV/AIDS are 40 to 54 years old.
Experts note that more women with HIV are now living to midlife and beyond — thus the importance of understanding the challenges that menopause poses for them.
Recent findings suggest that women with HIV do face a bigger menopause challenge than uninfected women because they have worse menopause symptoms.
Whether, how, and when the process of transitioning through menopause affects cognition have been debated.
Large-scale studies of healthy women indicate that the menopause-related thinking deficiencies are modest, limited to the time leading up to menopause (“perimenopause”), and rebound after menopause.
But in these women who underwent mental skills testing, menopause symptoms and mood symptoms did affect thinking skills.
Mental processing speed and verbal memory were more related to depression, anxiety, and hot flashes in both HIV-infected and healthy women than the stage of menopause.
Hot flashes in particular correlated with slightly lower mental processing speed, a skill that is also affected by the HIV virus.
Depression correlated with decreased verbal memory, processing speed, and executive function (such as planning and organizing).
Of all the symptoms measured, anxiety stood out as having the greatest impact on thinking skills, and the impact was much greater on women with HIV. Anxiety particularly affected their verbal learning skills.
“So treating anxiety may be key to improving the lives of midlife women with HIV,” concluded the investigators.
“Unfortunately, HIV infection is associated with modest deficits in multiple domains of cognitive function, even in women who regularly take their HIV medications.
“These depression and anxiety symptoms add to those cognitive vulnerabilities, but can be treated,” said senior author Pauline M. Maki, Ph.D., from the University of Illinois at Chicago.
