“Hormonal status can affect cognitive function
and over the years there has been conflicting evidence
regarding the risk of dementia and HRT use”.1

Umbrella

What may the Hormone Therapy and Dementia Umbrella include?

Depending on the Source (DotS) this Umbrella may include:

  • Hormone (Replacement) Therapy H(R)T
  • Hormone Medicines
  • Hormone Replacement Therapy (HRT)
  • Hormone Therapy (HT)
  • Hormones
  • Medicines for Hormone Replacement Therapy
  • Menopausal Hormone Therapy (MHT)

  • Menopause Medicines

Date

What can it be important to be clear about with hormone therapy (HT) information?

It can be important to be clear about the date of all information including the date of HT information, because this information may have been updated.

Symptoms or Chronic Conditions

What can it also be important to be clear about with HT information?

It can also be important to be clear about whether HT information is about the use of HT for the management of menopausal symptoms such as hot flushes, night sweats and vaginal dryness or for the prevention of chronic conditions such as dementia, cardiovascular disease, cancer and osteoporosis.

Menopausal Hormone Therapy and Dementia Study, 28 June 2023

What is the Conclusions of the Menopausal Hormone Therapy and Dementia: Nationwide, Nested Case-Control Study, published 28 June 2023?

The Conclusions of the Menopausal Hormone Therapy and Dementia: Nationwide, Nested Case-Control Study is:

Conclusions Menopausal hormone therapy was positively associated with development of all cause dementia and Alzheimer’s disease, even in women who received treatment at the age of 55 years or younger. The increased rate of dementia was similar between continuous and cyclic treatment. Further studies are warranted to determine whether these findings represent an actual effect of menopausal hormone therapy on dementia risk, or whether they reflect an underlying predisposition in women in need of these treatments”.2

In Menopausal Hormone Therapy and Dementia [Editorials], published 28 June 2023, in response to the above study Menopausal Hormone Therapy and Dementia: Nationwide, Nested Case-Control Study, what do the authors note:

In Menopausal Hormone Therapy and Dementia [Editorials], the authors note:

“Pourhadi and colleagues’ new study reported an association with increased risk of dementia even in women using menopausal hormone therapy before the age of 55 years for less than or equal to five years, which is within the age range recommended by the North American Menopause Society. Their findings contradict those of the WHIMS-Y trial and other trials that reported no effect on cognitive function among women who were randomly assigned to hormone therapy in early menopause. Although, longer follow-up is needed to determine participants’ dementia risk later in life”.3

Dementia Risk Under the Age of 60 Years

Under the age of 60 years, can starting hormone therapy (HT) increase the risk of dementia?

On page two in HRT Benefits and Risks, published November 2020, the (British) Women’s Health Concern note:

“Hormonal status can affect cognitive function and over the years there has been conflicting evidence regarding the risk of dementia and HRT use. Based on the current evidence, women can be reassured that HRT is unlikely to increase the risk of dementia or be detrimental to cognitive function in women initiating HRT under the age of 60 years”.4

Dementia Risk Older than 65 Years

Older than 65 years, can starting HT increase the risk of dementia?

On page one in Deciding About Hormone Therapy Use: Potential Risks, published July 2022, the North American Menopause Society (NAMS) note:

“If started in women aged older than 65 years, HT might increase the risk of dementia”.5

Reducing Dementia Risk With HT

Is HT recommended to reduce the risk of dementia in women experiencing the menopause?

No. On page three in the Joint Position Statement By the British Menopause Society, Royal College of Obstetricians and Gynaecologists and Society for Endocrinology on Best Practice Recommendations for the Care of Women Experiencing the Menopause, first published online 10 June 2022, one of the recommendations is:

Hormone Therapy and Dementia

  • “Women should be reassured that HRT is unlikely to increase the risk of dementia or to have a detrimental effect on cognitive function in women initiating HRT before the age of 65. However, HRT should not be initiated for the purpose of reducing the risk of dementia in women experiencing the menopause. National as well as international recommendations do not support the use of HRT for the primary or secondary prevention of dementia”.6

In Hormones and Dementia: Does Hormone Replacement Therapy Reduce Dementia Risk? the (British) Alzheimer’s Society elaborate on:

“The research into whether taking oestrogen (as part of HRT) can reduce women’s risk of dementia has been mixed. Some studies suggest that oestrogen may reduce dementia risk whilst others say it increases it”.7

Documentary: Sex, Mind and the Menopause

What did the Channel 4 documentary Davina McCall: Sex, Mind and the Menopause discuss about HT and dementia?

In Menopause: HRT’s Brain-Protecting Effect May Be Overstated, published 11 May 2022, the authors note:

“The documentary, called Sex, Mind and the Menopause, discussed how the menopause can cause a range of brain-related symptoms, including brain fog, mood changes and memory problems. It also suggested that taking hormone replacement therapy (HRT) some years before the menopause may be the solution to these problems – alongside potentially halving a woman’s risk of developing dementia”.8

In Menopause: HRT’s Brain-Protecting Effect May Be Overstated the authors response to the Documentary also includes:

“Hormone replacement therapy can be effective for many women in alleviating a range of menopausal symptoms, particularly hot flushes. Whether HRT can prevent dementia or alleviate brain-related symptoms due to the menopause is still unclear. But fortunately, any brain changes that happen because of the menopause are usually temporary”.9

Health Care Provider

What if I would like to start HT?

If you would like to start HT, it may be in your best interest to also choose to talk to your health care provider about this.

On page one in Deciding About Hormone Therapy Use the NAMS elaborate on:

“Every woman is different, and you will decide about whether to use HT based on the severity of your symptoms, your personal and family health history, and your own beliefs about menopause treatments. Your healthcare professional will be able to help you with your decision”.10
