Many ladies anticipate sizzling flushes, dry pores and skin and night time sweats once they attain the menopause. However the impact the menopause can have on the mind is never talked about. That is one thing a current Channel 4 documentary introduced by Davina McCall explored.
The documentary, referred to as Intercourse, Thoughts and the Menopause, mentioned how the menopause could cause a variety of brain-related signs, together with mind fog, temper adjustments and reminiscence issues. It additionally recommended that taking hormone substitute remedy (HRT) some years earlier than the menopause stands out as the answer to those issues – alongside doubtlessly halving a girl’s danger of creating dementia.
With round 4.4 million ladies of working age going by the menopause within the UK, it’s clear that we want options to assist these affected by brain-related and different menopause signs. However HRT won’t dwell as much as what the documentary recommended it to be.
Mind adjustments
Round 23% of girls expertise measurable adjustments in mind perform throughout menopause – particularly to their reminiscence. These adjustments sometimes happen within the early levels, throughout perimenopause (the transitional interval earlier than menopause, sometimes between 40 and 44 years of age when oestrogen ranges start to drop and the frequency and depth of intervals begin altering).
That is one thing the documentary touched on, with one physician utilizing mind scans of perimenopausal ladies to indicate that mind exercise was 25% decrease in contrast with premenopausal ladies (the time earlier than perimenopause). Nevertheless, the documentary didn’t present viewers that these mind adjustments are normally non permanent – usually reversing a few years after reaching the menopause – when a girl now not has intervals. That is sometimes between 45 and 55 years of age.
These non permanent mind adjustments could also be brought on by different menopause signs that may have an effect on sleep, corresponding to night time sweats. Since sleep performs an essential position in mind perform, not sleeping correctly may result in focus and reminiscence issues. No proof thus far has conclusively proven whether or not or not the hormonal adjustments that occur throughout this era are the reason for mind adjustments in people.
Whereas there’s good proof that HRT will help cut back the severity of some menopause signs (together with sizzling flushes and night time sweats), it’s much less sure whether or not such therapies have any long-term profit on reminiscence and mind perform.
Dementia danger
One other argument the documentary makes is that taking HRT can considerably cut back a girl’s danger of creating Alzheimer’s illness – the most typical type of dementia. They drew on the outcomes of an American research of over 400,000 ladies that confirmed those that used HRT had a 50% decrease danger of dementia. This was very true in the event that they have been taking pure hormones, corresponding to oestradiol (an oestrogen steroid hormone).
However there’s one key difficulty with one of these observational research. Earlier research have proven that ladies who determine to take HRT have been higher educated, exercised frequently, had a more healthy weight and decrease blood strain and levels of cholesterol in contrast with ladies who selected to not take HRT. All of those elements are identified to lower dementia danger.
Whereas the research took these elements into consideration, having a superb training or a wholesome life-style should have had a larger affect on decreasing dementia danger than taking HRT by itself throughout the menopause did.
Girls who determine to take HRT could also be much less prone to develop dementia due to their life-style.

Whereas a big UK research confirmed that taking HRT throughout the menopause can decrease a girl’s danger of being recognized with dementia, this impact was a lot smaller (solely round 8-12% decrease) – and was solely seen in ladies taking the hormone oestradiol. It’s value noting that this research regarded a each ladies who had skilled pure menopause in addition to those that had early menopause due to surgical procedure. It’s believed that untimely surgical menopause (earlier than the age of 40) will increase dementia danger except these ladies take a substitute oestrogen therapy – corresponding to oestradiol. So whereas the research confirmed decrease dementia danger in some ladies taking this hormone remedy, this may solely have been the case for individuals who had an already elevated danger due to early menopause. It’s additionally value noting that total, there was no affiliation between taking hormones throughout the menopause and dementia within the UK research.
This UK research additionally confirmed that taking oestrogen alongside progesterone (the usual hormone therapy for the menopause prescribed to ladies who nonetheless have a womb), both eradicated the useful impact of oestrogen therapy alone – and even elevated the chance of dementia barely. Earlier research have additionally proven an elevated danger of dementia when taking a mix hormone – although this danger was sometimes seen in ladies who have been over 60 or in the event that they have been taking hormones for greater than ten years. Giving these older ladies intercourse steroids has been related to unfavorable results, accelerating harm to the mind cells.
It’s additionally value noting that taking mixed hormone therapies for greater than 5 years is linked to a larger danger of breast most cancers – although this danger is small, particularly in comparison with, say, the chance of most cancers from being chubby or smoking. As such, most medical tips recommend that taking mixed hormones for menopause signs is secure for as much as 5 years after the menopause.
Hormone substitute remedy could be efficient for a lot of ladies in assuaging a variety of menopausal signs, significantly sizzling flushes. Whether or not HRT can forestall dementia or alleviate brain-related signs as a result of menopause remains to be unclear. However luckily, any mind adjustments that occur due to the menopause are normally non permanent.
