Weight gain, mood swings, hot flashes, vaginal dryness – these are symptoms that most women associate with menopause. Another less talked about symptom that can be caused by menopause is: head foga term commonly used by menopausal women to describe a sudden clouding of memory and concentration.
Brain fog can be a warning sign for dementia and other serious illnesses. Especially since research has linked menopause to dementia. But just because menopause causes hormonal changes that cause occasional problems with memory or concentration doesn’t necessarily mean there’s something wrong.
Why is menopause related to dementia?
Currently, 65% of people with dementia are women. The biggest risk factor for dementia is age, and although women have a longer life expectancy than men, age alone does not completely explain this difference.
Scientists currently do not fully understand why women develop dementia at higher rates than men, but one leading theory supported by recent research is that it may be related to the hormone estrogen. Both men and women produce estrogen, but women have significantly higher amounts of it because it is the primary female hormone.
During menopause, estrogen levels drop, triggering a series of reactions in the body. Men, on the other hand, produce testosterone at a more stable rate throughout their lives. A certain amount of testosterone circulating in the body is converted to estrogen in the brain through a process called aromatase.
Women who go through menopause have lower estrogen levels in their brains than men of the same age because men usually don’t have testosterone levels that drop as dramatically as women lose estrogen during menopause.
This theory correlates with recent research linking early menopause and dementia. a 2022 survey The researchers looked at health data for 154,291 postmenopausal women in the UK and found that women who went through menopause around age 45, which is considered early menopause, were 30% more likely to be diagnosed with the disease before age 65 than women who went through menopause at age 50 (the average age for women in the US and UK).
Brain fog and dementia – is there a difference?
Brain fog is a temporary loss of memory and concentration, whereas dementia is a progressive chronic disease. But even the slightest change in cognitive function can cause panic about Alzheimer’s disease, the most common form of dementia. There’s no need to panic if your memory deteriorates a little as you get older. It is very common for women after the age of 40 to experience brain fog, and it can be exacerbated by menopause.
If you’ve always had a good memory and had no trouble multitasking or remembering to-do lists, it can be unpleasant to walk into a room and then realize you’ve forgotten why you entered it. However, it may be normal memory loss associated with aging.
According to alzheimer’s disease associationnormal brain fog symptoms are:
- May need help remembering things like using new technology
- sometimes make mistakes when balancing numbers
- Difficult to place the right words
- make decisions you wouldn’t normally make
- Losing frequently used items
- I have a certain way of doing things and get irritated when something interrupts my daily routine.
- Feeling tired from work, family, and regular social obligations
However, if you’re experiencing any of the following 10 warning signs, the Alzheimer’s Association recommends talking to your doctor.
- Finding it very difficult to solve problems or plans, such as paying bills or following simple steps
- Persistent memory loss that interferes with daily life
- confusion of time and place
- You have trouble doing familiar tasks, such as driving to places you always go.
- Have problems understanding spatial relationships and visual images
- Leaving or finding things in places you wouldn’t normally put them, such as leaving your TV remote in your car.
- Poor or impaired judgment when handling daily tasks such as finances or personal hygiene
- Changes in mood or personality (such as turning on hair triggers when something is out of your comfort zone)
- Increased withdrawal from social activities and work
Is hormone replacement therapy effective?
Although more research is needed to investigate the relationship between hormones and dementia, some recent studies raise the possibility that hormone replacement therapy may help prevent Alzheimer’s disease. hormone replacement therapy (HRT) is a common treatment for menopausal symptoms.
THere we introduce two types of HRT (also known as combination therapy): estrogen therapy and estrogen-progesterone therapy (EPT). As the name suggests, estrogen therapy simply involves ingesting estrogen. Estrogens may be administered by your health care provider in a variety of forms, including topical creams or gels, oral tablets, suppositories, and vaginal rings.
Combination therapy combines doses of estrogen and progesterone (also known as progestin). Progestin helps lower the risk of uterine cancer. In women whose uterus is intact and whose periods have stopped, the incidence of uterine cancer is higher when treated with estrogen alone. When menstruation stops and the endometrium stops shedding, the effects of estrogen cause cells in the uterus to overgrow, which can lead to cancer.
a 2023 survey A study published in Frontiers in Aging Neuroscience found that women who took hormones to treat menopausal symptoms in midlife were less likely to develop dementia than women who did not take estrogen. However, this was not the case for women over 65 and taking estrogen.
Although clinical trials have generally not found that estrogen prevents dementia, the new study suggests that supplementing with estrogen early in midlife, when menopause begins, may prevent or slow the progression of Alzheimer’s disease.
Additionally, while estrogen monotherapy is typically only used in women who have had a hysterectomy, this analysis showed that progestins used in combination therapy may blunt the protective effects of estrogen (although the researchers note that the data are highly variable and further research is needed).
If you’re approaching menopause and are concerned about the possibility of dementia, discuss your options with your health care provider who can advise you on the best course of action.
