There’s new research that shows the first biological clues to why women are affected more than men when it comes to the development of the Alzheimer’s disease. It also shows that this is the most common form of dementia, which also varies depending on the sex of the person.
At the Alzheimer’s Assn. International Conference, scientists have shown pieces of evidence that the disease actually spreads differently when it comes to the brains of women and men. Some other research has shown that there are newly identified genes that have a role in this risk.
It is worth mentioning that Two-thirds of Alzheimer’s cases in the U.S make women the top of the scale, and it is certainly not because they live longer. When it comes to this disease, there’s also a biological underpinning for sex differences.
Are genes to blame for this?
Studies before this have shown that at any age, women are actually more likely to develop Alzheimer than men. Scientists also know that there is a gene variant, that’s called APOE-e4, that raises this risk more for women than for men.
Moreover, women that are in the early stages of the disease can live without a diagnosis, due to the fact that they tend to better on those verbal tests that are required – they do better than men, which is kind of a mask for the damage that Alzheimer does. This new study comes with even more pieces of evidence, and many possible explanations for this mysterious variation between how men and women develop this disease.
Researchers from the Vanderbilt University have found differences in how a specific protein that destroys nerve cells, called tau, spreads in the brains of women. Then, they compared it with how it covers in the brains of men. They found out that tau was correlated with the nerve networks.
