The Largest Alzheimer's Genetics Study Yet Found 48 New Links. The Most Promising Clue Isn't About Memory
Inc.com • • health
Key Points:
- An international research team analyzed genetic data from about 2.8 million people and identified 127 DNA regions linked to Alzheimer’s disease, including 48 new associations.
- Published in Nature Neuroscience, this is the largest genetic study on Alzheimer’s to date, providing new insights into the disease's development, especially the roles of brain immune cells and certain nerve cells.
- The study combined data from 30 research groups, involving over 109,000 diagnosed individuals and 74,000 with affected parents, enabling detection of genetic links missed in smaller studies.
- Researchers highlighted the importance of immune processes and identified new genetic risk factors connected to specific biological mechanisms and other brain cell types.
- The newly discovered genetic regions may guide future research and drug development by pointing to potential biological mechanisms underlying Alzheimer’s disease.
