SWHR Engages on Migraine and Women’s Health

By | Blog Post, Event, News

Migraine is the second leading cause of global disability, affecting 1.04 billion individuals worldwide and more than 47 million in the U.S. alone. Three times as prevalent in women compared to men, this debilitating disease continues to be under recognized.

The event’s speakers with Amy M. Miller, PhD, CEO of SWHR

On October 2, 2017, the Society for Women’s Health Research (SWHR®) convened interdisciplinary thought leaders at the George Washington University Milken School of Public Health for a panel discussion that included patients, practitioners, and the employer perspective.

“Only a fraction of individuals with migraine are appropriately diagnosed and treated,” explained panelist Jelena Pavlovic, MD, PhD, a neurologist at Albert Einstein College of Medicine. Patient advocate, Katie Golden, who experienced her first migraine when she was five years old, said she was lucky because her parents took her complaints seriously. However, her chronic migraine still resulted in her becoming disabled at age 30, causing her to drastically alter her career plans.

Despite migraine’s high prevalence, more education and deeper knowledge within the medical community is needed. The number of headache specialists in the U.S. is lacking significantly, said Dr. Pavlovic, with approximately one headache specialist for every 90,000 Americans with migraine. Five states currently have none.

The economic burden of migraine is staggering. In the U.S. alone, 113 million workdays are lost to migraine each year, costing employers more than 13 billion dollars. The costs of treating chronic migraine rise substantially when patients have one or more additional chronic conditions. Katy Spangler, senior vice president of the American Benefits Council, highlighted the role of emerging health policy concepts, such as value-based insurance design (VBID) that encourages patient utilization of high value services to drive better health and reduce costs. Spangler encouraged the migraine community to engage in benefit design and cost issues. “Let’s do a better job upfront, so people are healthier and happier, they’re more productive, and [everyone involved is] saving money.”

The public forum represents an expansion of SWHR’s successful scientific work, and enables additional, broader issues on migraine to be addressed. “SWHR looks forward to continuing to bring attention to these issues through the formation of a multi-year Migraine Network beginning this fall,” said SWHR President and CEO Amy Miller, PhD.

The goals of the future Migraine Network are to raise public awareness, change the perception of migraine, and to coordinate the diverse advocacy community with the intention of providing patients with tools to improve their healthcare. Furthermore, it will engage coverage, payment, and access policies. Such goals will be done through tangible educational materials, public forums, coalition building, publications, and advocacy activities.

SWHR is grateful for the support of the sponsors who made Migraines Matter: Beyond Burden to Value possible: Amgen, Eli Lilly, Novartis, and The Allergan Foundation.

Menopause, Memory, and Alzheimer’s Disease

When women think about menopause, they typically think about hot flashes. New research shows that memory problems are a common but under-recognized menopausal symptom.

Memory problems emerge during perimenopause, the time around the final menstrual period, before many women even realize that they are “going through the change.” Early research studies have documented an increase in memory complaints, such as forgetting names, as a woman enters the menopausal transition, while more recent studies have revealed measurable changes in verbal memory as a woman transitions through menopause [1,2].
Although decreases in memory are a normal part of aging, age does not account for the changes in memory that occur when a woman transitions through menopause. Similarly, although sleep disturbances and mood symptoms are common and can affect memory, they do not account for memory problems during this transition. Preliminary research links memory problems to hot flashes, (when hot flashes are measured objectively- using ambulatory monitors) but further research on this issue is needed [3,4]. The good news is that memory problems that can emerge during perimenopause seem to improve during the postmenopausal years [2].

Hormonal factors appear to play a role in memory changes during the menopausal transition. The ovaries are the primary source of estrogen in premenopausal women. In women who have not yet reached their final menstrual period, having their ovaries surgically removed leads to a decline in verbal memory, which is reversed when they take estrogen therapy [5]. Similarly, removing ovaries before age 48 has been associated with a 70 percent increased risk of cognitive impairment or dementia [6], but use of estrogen therapy until the typical age of menopause negates that risk.

When women are in their 50s and have transitioned through menopause, taking hormones does not seem to affect memory performance. For example, memory does not change when women begin hormone therapy within five years after their final menstrual period [6,7]. Meanwhile, initiating hormone therapy later in life – after age 65 – can actually increase the risk of memory problems and dementia [8,9]. It might be that women with hot flashes particularly benefit from hormone therapy. Initial evidence indicates that hormone therapy can improve memory and brain function in women with moderate to severe hot flashes [10], but more extensive studies are needed. Similarly, it is unknown how taking birth control pills containing estrogen can influence memory in perimenopausal women.

Women show a lifelong advantage in verbal memory compared to men. Interestingly, this advantage might make it more difficult for clinicians to detect a memory problem in women who are in the early stages of Alzheimer’s disease (AD). Before developing AD, patients transition though a stage called amnestic mild cognitive impairment, or aMCI. At this stage, memory problems exceed what is expected for age but do not reach the level of severity seen in AD. The female advantage in verbal memory persists in the aMCI stage. Consequently, women perform better than men despite showing the same level of AD disease on brain scans [11-13]. Although this could be seen as an advantage, women may be diagnosed with aMCI or AD at a later and more severe stage of the disease than men. Researchers are now exploring whether it might be useful for clinicians to use different cut-offs for memory tests in women and men, so that AD can be detected earlier in women.

Together, these studies demonstrate the important need to address how brain aging differs between women and men. By examining how menopause, estrogen, and other factors contribute to those differences, we can improve efforts to prevent, detect, and treat memory problems, and memory disorders such as AD. This is especially relevant for women, who make-up 3.2 million out of the approximately 5 million individuals in the U.S. living with AD. It is estimated that the prevalence of AD will triple by 2050 [14], and the associated costs will exceed $20 trillion U.S. dollars. For this reason, it is imperative that we continue to work together to fund AD research and support studies that recognize and address the ways in which this deadly disease can affect women and men differently.

There is still more to be done in investigating new AD risk factors and discerning how established risk factors vary by sex and gender. The Society for Women’s Health Research’s Interdisciplinary Network on Alzheimer’s Disease is committed to advocating for these goals in order to inform prevention and treatment, providing guidance for research, clinical trials, and policy.
