Welcome!

 

This is your host Ralph Sanchez, and this is episode #21, I am expanding on the last episode, #20, titled: “Estrogen Deficiency and Cardiometabolic Disease Underlies a Woman's Greater Risk for Alzheimer's Disease”.

 This episode—part two of this two-part episode series—on the linkages between perimenopausal and postmenopausal estrogen declines in women and the risk for age-related disorders— will focus primarily on three types of estrogen:

  • Endogenous estrogen (the kind you make).
  • Estrogen replacement therapies (the kind you take), and
  • Phytoestrogens (the kind you eat and supplement with),

and what they potentially represent in a woman’s risk for dementia and late-onset Alzheimer's disease (LOAD).

The role of  endogenous estrogen is not often inserted into the discussion with regard to a woman’s risk for LOAD and it may be an important risk factor to weigh into a risk evaluation.

Note that today’s overview on the estrogen a woman naturally produces throughout her reproductive lifespan—endogenous estrogen—was not part of a previous episode, # 10, that focused on the importance of estrogen replacement therapy in women at midlife.

Plus, I’ll revisit estrogen replacement therapy (ERT) and some very important and more recent studies findings on that topic to be aware of, and how plant estrogens, or phytoestrogens, may substitute for ERT.

Since this will be a lengthy and dense overview on all of this here today, this summary will be a very abbreviated review of what I covered.

 First, I’ll reiterate that the discussion and overview on postmenopausal estrogen deficiency as a risk factor for dementia and LOAD should not be a compartmentalized overview on estrogen’s role solely on neurological health.

 As I detailed in the last episode, the role of estrogen in cardiometabolic health is a significant component that connects a woman’s vascular health, blood flow to the brain and atherosclerosis, in the risk for brain lesions known as white matter hyperintensities (WMHs).

 And the brain damage associated with said brain lesions (WMHs) are a significant biomarker linked to the risk for cerebrovascular disease and stroke, vascular dementia, and LOAD.

Uncontrolled hypertension and atherosclerotic vascular disease restrict blood flow to the brain, and the vital nutrients and oxygen needed to fuel brain function.

Please listen in to episode #19 here in which I leverage recent studies on Viagra to make a point about several structure and function aspects of vascular health in aging individuals—both women and men—that are vital and modifiable risk factors for LOAD and vascular dementia.

Estrogen Exposure Throughout a Woman’s Lifetime

For decades, the research centered around the role of estrogen and estrogen replacement therapy in the risk for late-onset Alzheimer's disease (LOAD) has yielded conflicting results that ranged from:

  • harmful, to
  • no benefit to,
  • protective.

In the last episode I explained why there is the seemingly conflicting outcomes that are associated with ERT, so please do listen in to that episode, #20.

Regardless, the preponderance of that research on estrogen therapy in the potential risk for LOAD has dealt with exogenous estrogen therapies.

 However, there is another significant group of studies that must also be noted, and those are the ones that examined the link between the length of a woman’s reproductive years and the endogenous estrogen exposure during those years.

Endogenous Estrogen—Please listen in for the rest of this story!

Ralph Sanchez, MTCM, CNS, D.Hom.

Ruthie's Table 4

Ruthie's Table 4

For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
