Loss of the Y chromosome can now be linked to a higher risk of Alzheimer’s disease. This is shown in a new study by a research team that includes Swedish Brain Power researchers published today in the American Journal of Human Genetics.
Loss of the Y chromosome in a proportion of blood cells occurs in approximately 20 percent of all men over 80 years of age and has previously been linked to increased risk of cancer. Now, an international research group, where the Swedish Brain Power researchers Lars Lannfelt and Martin Ingelsson at Uppsala University are included, noted that this also applies to Alzheimer’s disease.
The result could lead to the development of a test to find out which ones are at risk of Alzheimer’s.
