The question we all want answered is: Does HRT raise dementia risk? In simple terms, a huge review has just found <b>no evidence<\/b> that menopause hormone therapy (HRT) either increases <i>or<\/i> decreases the risk of dementia in postmenopausal women.<\/p>\n<p class=\"p1\">If you\u2019d like a simple overview of symptoms and treatment options, you can also read my\u00a0<a href=\"https:\/\/www.silverlocks.org\/en\/menopause-the-complete-guide-for-women-over-45\/\"><b>Menopause Guide for Women Over 45<\/b>.<\/a><\/p>\n<h2>Does HRT Raise Dementia Risk? What did the new research actually do?<\/h2>\n<p>The World Health Organization asked an international team of researchers (based at <a href=\"https:\/\/www.ucl.ac.uk\/news\/2025\/dec\/menopause-hormone-therapy-does-not-appear-impact-dementia-risk\" target=\"_blank\" rel=\"noopener\">UCL<\/a>, <a href=\"https:\/\/news.exeter.ac.uk\/faculty-of-health-and-life-sciences\/menopause-hormone-therapy-does-not-appear-to-impact-dementia-risk\/\" target=\"_blank\" rel=\"noopener\">Exeter<\/a> and others) to go through the best available studies on HRT and brain health. They wanted to answer one big question:<\/p>\n<p>Does taking menopause hormone therapy change a woman\u2019s risk of developing dementia or mild cognitive impairment later in life?<\/p>\n<p>To do this, they carried out a <b>systematic review and meta-analysis<\/b> \u2013 which basically means they:<\/p>\n<ul>\n<li>searched all major medical databases for relevant studies from 2000 onwards,<\/li>\n<li>picked out the higher-quality ones,<\/li>\n<li>and then combined the results to see the overall pattern.<\/li>\n<\/ul>\n<p>In total, they included <b>10 studies<\/b> (1 randomised controlled trial and 9 observational studies) with <b>over one million women<\/b>. They looked at different types of menopause hormone therapy (oestrogen-only, combined oestrogen\u2013progestogen, tibolone) and asked whether using HRT was linked to a higher or lower risk of:<\/p>\n<ul>\n<li>dementia (including Alzheimer\u2019s disease), or<\/li>\n<li>mild cognitive impairment (MCI), which is like an in-between stage of thinking problems that aren\u2019t yet dementia.<\/li>\n<\/ul>\n<h2>The main finding: HRT doesn\u2019t seem to change dementia risk<\/h2>\n<p>The headline is very straightforward:<\/p>\n<ul>\n<li>The review found no evidence that HRT use either increases or decreases the risk of dementia in post-menopausal women.<\/li>\n<li>This was true even when they looked at timing (when you start HRT), how long women used it, and what type of HRT they took.<\/li>\n<\/ul>\n<p>In other words, in the studies we have so far, women on HRT did <b>not<\/b> have a higher risk of dementia than women who didn\u2019t take it \u2013 but they also didn\u2019t have a lower risk either.<\/p>\n<p>This is important because:<\/p>\n<ul>\n<li>In the past, some warnings suggested HRT might <b>increase<\/b> dementia risk.<\/li>\n<li>More recently, some headlines suggested HRT might <b>protect<\/b> against Alzheimer\u2019s.<\/li>\n<\/ul>\n<p>This big WHO-commissioned review basically says: based on current evidence, <b>neither of those claims is supported<\/b>.<\/p>\n<h2>What about early menopause or different types of HRT?<\/h2>\n<p>The researchers also looked at:<\/p>\n<ul>\n<li><b>Age at menopause<\/b>, including early menopause and premature ovarian insufficiency.<\/li>\n<li><b>Timing<\/b> (starting HRT close to the menopause vs much later).<\/li>\n<li><b>Duration<\/b> (how many years women used HRT).<\/li>\n<li><b>Type<\/b> of HRT (oestrogen-only vs combined, etc.).<\/li>\n<\/ul>\n<p>Even with all those subgroup analyses, they <b>still didn\u2019t find clear evidence<\/b> that HRT changed dementia risk in either direction.

HRT decisions should focus on your symptoms, overall health and personal risk factors, discussed with a healthcare professional.<\/p>\n<h3>If HRT doesn\u2019t change dementia risk, how can I protect my brain?<\/h3>\n<p>Look after blood pressure, cholesterol, movement, sleep, social connection, alcohol and smoking. These lifestyle and medical factors matter more for long-term brain health.<\/p>\n<h2>My experience<\/h2>\n<p>Hearing the news about this research felt very positive to me. I lost my mother to Alzheimer\u2019s at a very young age \u2013 she was only 69 \u2013 so that fear is always sitting quietly at the back of my mind. I decided to use HRT because my menopause symptoms were affecting my daily life far too much, but like many women, I\u2019ve often questioned that choice. Should I take HRT and feel better now, while worrying I might increase my chances of Alzheimer\u2019s later? Or should I just \u201cput up\u201d with the symptoms and hope they pass? It\u2019s a painful dilemma, and one each of us has to answer in our own way.<\/p>\n<p>That\u2019s why I felt genuinely relieved when this new research showed that standard menopause hormone therapy does not appear to increase or reduce dementia risk. It doesn\u2019t magically remove all the other questions around HRT, but it does take one very heavy worry off my shoulders. Among all the potential \u201cwhat ifs\u201d we live with, it\u2019s comforting to know that, based on current evidence, Alzheimer\u2019s is not on the list of things HRT is likely to cause.<\/p>\n<p><em>Disclaimer \u2013 This article is for general information only and doesn\u2019t replace personalised medical advice, diagnosis or treatment.
