A research study conducted by researchers at the University of Gothenburg, Sweden revealed that women who have had childbearing periods for more than 38 years are more likely to develop dementia later in life, and the study found that the risk of developing dementia and Alzheimer’s disease increases respectively with each additional year in which the woman remains able to conceive..
According to a newspaper report neuroscience A population study from the University of Gothenburg showed that women with the longest reproductive period had a higher risk of developing dementia in Old age, Compared to women who have been fertile for a shorter period.
Among the women who studied with a shorter childbearing period (32.6 years or younger), says Gina Najjar, MD and PhD student at the University of Gothenburg, 16% (53 out of 333 individuals) developed dementia, in the group of women whose fertility period was longer ( 38 years or older), 24% (88 out of 364) had dementia, so the difference was 8 percentage points.
The study shows that the risk of developing dementia and Alzheimer’s disease increases successively with each additional year in which the woman remains fertile, the link was stronger for those with dementia that appeared after the age of 85, and the effect was more related to age at menopause..
These results continued after adjusting for other influencing factors, such as educational attainment, physical activity, body mass index, smoking, and cardiovascular disease. On the other hand, no association was found between risk of dementia, age at menstruation, number of pregnancies, duration of breastfeeding, or estrogen. External taken as hormonal replacement therapy (HRT) Or oral contraceptives.
Several studies have investigated how estrogen in the HRT form affects the risk of developing dementia. Some studies show that the risk of developing dementia decreases and others are higher, especially in women who take estrogen late in life..
In the current study, Gina Najjar, instead, investigated the long-term relationship between factors related to endogenous estrogen and dementia..
The study shows that the risk of developing dementia and Alzheimer’s disease increases successively with each additional year in which the woman remains fertile, and the study showed that most women who have delayed menopause do not develop dementia because of this factor alone, however, the study may provide evidence for why women are exposed. Men have a higher risk of developing dementia after the age of 85, which is the most common age for it to appear. On the other hand, Alzheimer’s disease begins to develop approximately 20 years before symptoms of the disorder appear..
