Women who underwent earlier menopause were more likely to develop a greater amount of damaged white matter in the brain decades later, a new study led by UC San Francisco found.\u00a0<\/p>\n
This damaged white matter, visible on MRI, has been associated with difficulties in attention, focus, executive functioning, and information processing.\u00a0<\/p>\n
The study is the first to identify a significant effect of earlier menopause many years later. It was published in JAMA Network Open<\/a>on Aug. 25 and funded by the National Institutes of Health.\u00a0<\/p>\n Researchers analyzed data from about 2,600 women who were followed from an average age of 78 for up to 18 years. They estimated that over a 10-year period, a woman whose menopause occurred earlier might accumulate a 15% higher volume of damaged white matter than a woman whose menopause occurred five years later.\u00a0<\/p>\n The researchers did not set a specific age cutoff for \u201cearlier\u201d menopause. In this study, they meant menopause occurring earlier than other participants. Among women who experienced natural menopause, the average age was 50. Among the roughly one-third who experienced surgical menopause, the average age was 43.\u00a0<\/p>\n \u201cInjury in the white matter becomes increasingly common as we age,\u201d said senior author Riley Bove<\/a>, MD, director of the UCSF Sex and Gender Enriched Program and Rosenberg Ach Family Endowed Professor in Neuroimmunology in the Weill Institute for Neurosciences<\/a>.\u00a0<\/p>\n \u201cAlong with aging itself, other conditions like hypertension, elevated blood sugar and cholesterol, and obesity can also contribute to this risk. Estrogen appears to provide some protection against these conditions, or against underlying brain vulnerability to injury, until it declines with menopause,\u201d said Bove.\u00a0<\/p>\n Earlier menopause was associated with a slightly faster decline in overall thinking ability and episodic memory, the brain\u2019s ability to recall specific personal events and experiences. The researchers also found an association between earlier menopause and earlier onset of Alzheimer\u2019s disease.\u00a0<\/p>\n \u201cThese findings show that timing of menopause can influence how the brain ages, even decades later,\u201d said first author M. Pia Campagna<\/a>, PhD, postdoctoral fellow in the UCSF Department of Neurology and the Weill Institute for Neurosciences. \u201cThere is a major effort to study the menopause window to identify interventions that could optimize brain health as women age.\u201d\u00a0<\/p>\n The participants were enrolled from two long-term studies, the Rush Memory and Aging Study and the Religious Orders Study, led by co-author David A. Bennett, MD, at Rush University. In their analyses, researchers drew from MRIs, autopsy data, and cognitive testing.\u00a0<\/p>\n Additional authors: Julie A. Schneider, MD, Lisa L.
