Summary

This study collected blood samples from over 2,200 people with Alzheimer's or other dementias, plus healthy volunteers, to search for genes linked to these diseases. Researchers aimed to identify new genetic causes and better understand how genes affect disease risk and progression. No treatment or cure was tested; the goal was purely to gather knowledge for future research.
