A strange relationship that links the total number of births with Alzheimer's disease

Al Wasat – Alzheimer's disease affects girls more than young people. Understand the underlying cause

Joint research conducted by the School of Natural Sciences at the Seoul National University has highlighted a link between the gestational history of girls and the likelihood of developing the disease. ; Alzheimer's.

The results showed that having five or more children increased the risk of Alzheimer's disease, but that the girl's exposure to one or more more incomplete had a significant protective effect against the disease.

The study included the status of pregnancy dates for more than 3,500 women, including information on total births, and the number of incomplete pregnancies due to abortion or miscarriage. spontaneous abortion.

Scientists then tested girls' memory and thinking skills to see if they develop Alzheimer's disease or signs.

The results showed that having five or more children makes girls 70 percent more likely to develop Alzheimer's disease.

Interestingly, girls who had an incomplete pregnancy were less likely to have the disease, scoring higher scores in memory and thought tests.

The researchers believe that the findings may be related to hormonal changes occurring during pregnancy, such as estrogen levels in the body of the girl in the eighth week of pregnancy, and continue to increase until 39 to about 40 times lower than normal levels.

"Modest levels of estrogen in the first trimester of pregnancy may be in the optimal range of protection for thinking skills," said Dr. Kee Wong Kim, co-author of the I & 39 ;study.
